The present study sought to investigate the effects of a self-talk intervention on free-throw performance under pressure. The experimental manipulation was designed using a video from a social media platform. Thirty male college basketball players were randomly assigned into two groups (i.e., control and experimental). The experimental protocol incorporated three trials of three free throws each. Psychophysiological stress was assessed by use of heart rate variability. The illusion of pressure was created using arena recordings of large crowds along with instructions for participants to visualize a high-pressure scenario. The results indicate that the self-talk intervention was sufficient to improve free throw shooting accuracy during the postintervention phase. Short-term heart rate variability reduced significantly for the control group and remained relatively stable for the experimental group. Self-talk appears to influence free throw accuracy during situations of psychosocial stress by inhibiting the influence of negative thoughts on peripheral physiological reactions and movement automaticity.

Purpose: To quantify and compare loads encountered in individual training sessions and games during noncongested and congested weeks in semiprofessional women basketball players. Methods: Using an observational, longitudinal design, 12 players from the same team had their external (PlayerLoad, relative PlayerLoad, and total and high-intensity inertial movement analysis variables) and internal load (session rating of perceived exertion [sRPE], sRPE-load, percentage of heart rate peak, and modified summated-heart-rate-zones load) monitored across a regular season. Training and game data were categorized into noncongested (0–1 game) and congested weeks (2–3 games). Linear mixed models and Cohen d effect sizes were used for analyses. Results: Comparisons between training sessions revealed higher (P <.05, d = 1.35–5.33) PlayerLoad, total inertial movement analysis, sRPE, and sRPE-load during training session 1 than training session 2 in congested weeks. Comparisons between training sessions and games revealed higher (P ≤.001, d = 1.10–1.66) sRPE and sRPE-load during games than training sessions 1 and 2 in noncongested weeks, alongside higher (P ≤.001, d = 1.87–3.55) sRPE during game 1 than training sessions 1 and 2 in congested weeks. Comparisons between games revealed higher (P <.05, d = 0.57–2.82) loads in game 3 during congested weeks compared with all other games. Conclusions: Training appeared to be tapered in congested weeks, likely to account for upcoming increases in game loading, but remained relatively consistent across sessions during noncongested weeks. Individual game loads remained relatively consistent but were noticeably increased when a third game was played in the week. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to assess the effect of playing different pick-and-roll (PnR) defensive tactical options during small-sided games (SSGs) on external and internal loads in female basketball players. Methods: Twelve female basketball players (age 28 [2] y; stature 175 [6] cm; body mass 65 [7] kg; playing experience 18 [4] y) belonging to a team competing in the Lithuanian second division were recruited for this study. Across 3 experimental sessions and in a randomized order, players performed 3 SSGs sharing the same features but using 3 defensive strategies on the middle PnR action: Switch, Trap, and Drop. External load was measured using PlayerLoad (PL); the number of accelerations, decelerations, and changes of direction, classified based on their intensities as low (<2.5 m·s−2), medium (2.5–3.5 m·s−2), and high (>3.5 m·s−2); and jumps categorized as low (<40 cm) and high (≥40 cm). Internal load was measured via rating of perceived exertion (RPE). Results: Higher PL values in SSGs including Trap defense were found compared with Drop (P <.001, ES = 0.69, moderate) and Switch (P =.001, ES = 0.60, moderate). Additionally, a higher number of accelerations was registered in Trap defense compared with Drop defense (P =.027, ES = 0.99, moderate). Trap defense also led to higher RPE compared with Switch (P =.003, ES = 1.49, large) and Drop (P =.004, ES = 1.42, large) defense. Conclusions: Different defensive strategies on the middle PnR can influence the external and internal loads during SSGs, and female basketball coaches should consider the high demand of the Trap defense when designing SSGs.

Purpose: The aim of this study was to explore the interday reliability of mechanical variables obtained from the horizontal and vertical force–velocity (FV) profiles in adolescent female basketball players. If found to be reliable, the associations between FV parameters (theoretical maximal force, velocity, and power), squat jump (SJ) height, 30-m sprint, and change of direction (COD) times were evaluated. Methods: After familiarization, SJ against incremental loads, 30-m sprint, and 505-COD tests were obtained twice in 36 adolescent female basketball players (age = 15.4 [1.2] y). Results: Reliability for vertical FV parameters was unacceptable, whereas 505-COD times and FV horizontal parameters (except for theoretical maximal power) showed a moderate to high reliability. 505-COD time was correlated with FV horizontal parameters (range: r = −.821, −.451), and a large association was observed with both SJ height (r = −.678, −.600) and 30-m sprint time (r =.813,.858). Conclusions: Due to low levels of strength, our athletes were not adequately prepared to obtain a reliable vertical FV profile. Practitioners can expect acceptable reliability of the horizontal FV profile. Given the association between COD performance and SJ height and 30-m sprint time, we encouraged practitioners with limited equipment at their disposal to use COD and/or 30-m sprint tests.

Humans are fascinated by the bipedal locomotor capacities at both ends of the athletic spectrum—sprinting speed and endurance. Some of the more popular field (eg, soccer, rugby, and lacrosse) and court (eg, basketball, tennis, and netball) sports utilize mixed energy systems requiring an interplay of both maximal sprinting speed (MSS) and maximal aerobic speed (MAS) to meet the high-intensity running demands of varying frequency, duration, intensity, and recovery. Recently, these locomotor capacities have been considered in combination to produce what is called the anaerobic speed reserve (ASR) as part of the locomotor profile concept (MSS, MAS, and ASR). The purpose of this narrative review is to (1) provide an overview of the locomotor profile concept; (2) review the assessment methods for estimating MSS, MAS, and ASR; (3) examine the age-, sex-, and maturity-associated variations in MSS, MAS, and ASR; (4) examine the trainability of MSS, MAS, and ASR in youth athletes; and (5) conclude with the practical applications using principles of long-term athlete development for training the locomotor profile in youth field and court sport athletes. Based on the available data in young male athletes, MSS, MAS, and ASR generally increase with age and across maturity groups and are trainable. Overall, decisions on training need to consider the sport demands, current fitness and maturity status, and targeted training adaptation sought. [ABSTRACT FROM AUTHOR]

Purpose: To assess the effect of whole-body cryotherapy (WBC) on postmatch recovery in basketball. Methods: Using a crossover design, 17 youth male players (age 16.2 [1.2] y, stature 190.5 [9.4] cm, body mass 79.2 [9.6] kg, experience 9.9 [3.9] y) completed 2 simulated matches, followed by WBC (4 min, −75 to − 85 °C) or a placebo intervention (CON). Countermovement-jump height, change-of-direction performance, 10- and 20-m sprint times, heart-rate variability (log-transformed squared root of the mean sum of the squared differences between R-R intervals [Ln-rMSSD]), muscle soreness, and perceived recovery (Perceived Recovery Status Scale [PRS]) were recorded at prematch, postmatch, postrecovery, and 24 hours postmatch. Additionally, Ln-rMSSD was recorded upon awakening on match day and the following morning. Results: Compared with CON, higher PRS values were reported in WBC at prematch and postrecovery (P ≤.026), while no significant between-interventions differences were found for any other measure (P >.05). Regarding the effect of time, our findings revealed that 20-m sprint times, Ln-rMSSD, and PRS deteriorated in both interventions from prematch to postmatch (ie, acute changes, P ≤.045), while muscle soreness worsened in WBC only (P ≤.003). Conversely, countermovement-jump height, change-of-direction, and 10-m sprint performance were unaffected by match play in the acute phase (P >.05), while none of the investigated measures showed impairments at 24 hours postmatch, compared with prematch (P >.05). Conclusions: Overall, these findings suggest that WBC was mostly ineffective for improving postexercise recovery in the investigated sample, with benefits observed for perceived recovery being potentially influenced by the participants' status at baseline (ie, higher prematch PRS scores in WBC compared with CON).

This study sought to understand the lived experiences of wheelchair basketball athletes from low- and middle-income countries of recent or current armed conflict and the meaning that they ascribed to their participation. Wheelchair basketball athletes (N = 108) from eight national teams participated in semistructured focus-group interviews. Study data were analyzed thematically using an interpretive descriptive approach. Three themes were developed: "I can do anything I want; not only basketball," self-concept changes through sport participation; "Now they see me as a respectable person," societal belonging through sport; and "I have motivated other disabled people," influence on nonparticipating disabled persons. The findings indicated that participation in wheelchair sports may help disabled persons see themselves as capable individuals on the court and in aspects of daily living, perhaps even peer role models for other disabled persons in their communities and countries.

This paper analyzes the strategic decision of basket choice in the National Basketball Association. Before games start, the away team chooses whether to play on offense in front of their bench in the first or second half. Based on eight regular seasons and 9,308 games, we identify the standard strategy for away teams to play on offense at their own benches in the first half. Results indicate that both home and away teams score more points when they play on offense in front of their bench. More importantly, there is a strategic advantage for the away team to play with the offense in front of the bench in the second half, deviating from the standard strategy in the league. Finally, we demonstrate that the choice of the basket for the away team can partially offset the home advantage under normal spectator conditions and entirely nullify it in ghost games.

In October 2021, National Basketball Association player Kyrie Irving was banned from competing for the Brooklyn Nets because of his resistance to being vaccinated for COVID-19. Two months later, the Nets softened that stance and allowed Irving to participate in road games. This study examines two prongs of the social media response to Irving's vaccination status. A total of 12,000 posts were collected from the U.S.-based Twitter (now known as X; 6,000) and the Chinese-based Weibo (6,000), covering the first week of coverage of Irving and the Nets' announcement. Results showed that Hofstede's cultural dimensions help explain the theme differences, with Twitter's comments reflecting more individualistic notions and lower power distance than Weibo. Moreover, Twitter users focused more on opinion-based expression themes, while Weibo users avoided commenting on the COVID-19 policy. These findings contribute to the literature by identifying the role culture plays in people's response to a social issue. [ABSTRACT FROM AUTHOR]

Purpose: Performing back squats with elastic bands has been widely used in resistance training. Although research demonstrated greater training effects obtained from adding elastic bands to the back squat, little is known regarding the optimal elastic resistance and how it affects neuromuscular performance. This study aimed to compare the force, velocity, power, and muscle activity during back squats with different contributions of elastic resistance. Methods: Thirteen basketball players performed 3 repetitions of the back squat at 85% of 1-repetition maximum across 4 conditions: (1) total load from free weight and (2) 20%, (3) 30%, and (4) 40% of the total load from elastic band and the remaining load from free weight. The eccentric and concentric phases of the back squat were divided into upper, middle, and bottom phases. Results: In the eccentric phase, mean velocity progressively increased with increasing elastic resistance, and muscle activity of the vastus medialis and rectus femoris significantly increased with the largest elastic resistance in the upper phase (P ≤.036). In the concentric phase, mean power (P ≤.021) and rate of force development (P ≤.002) significantly increased with increasing elastic resistance. Furthermore, muscle activity of the vastus lateralis and vastus medialis significantly improved with the largest elastic resistance in the upper phases (P ≤.021). Conclusion: Velocity, power, rate of force development, and selective muscle activity increased as the elastic resistance increased in different phases during the back-squat exercise.

Purpose: The study aimed to conduct a comparative analysis of physical performance indicators and assess the levels of performance monotony and strain experienced by basketball referees. Methods: The study involved the participation of 12 basketball referees (mean age: 40.0 [4.9] y) affiliated with the International Basketball Federation. The investigation was carried out throughout 2 density tournaments, wherein the maximum heart rate, average heart rate, performance monotony, and performance strain were documented for 3 variables. Results: The findings indicated significant variations in the mean heart rate, maximum heart rate, total distance monotony, total distance strain, the total number of sprints monotony, the total number of sprints strain, calories monotony, and calories strain (P <.05). Decreasing the density of elite-level basketball competitions has been observed to reduce the monotony and strain experienced by referees. However, this action does not increase motion distance or speed zones. Conclusions: The environmental stressors experienced by senior-level athletes (World Cup) differ from those encountered by younger athletes (World Cup Under 19). Further investigation is required to ascertain the potential effects of competition monotony and strain on decision-making processes and the overall quality of refereeing. [ABSTRACT FROM AUTHOR]

This study investigated the effects of the timing of caffeine (3 mg/kg body mass) ingestion on three-point shooting accuracy and other performance parameters during a basketball exercise simulation test (BEST). Eighteen college basketball players (mean ± SD: age = 24.4 ± 1.5 years, height = 181.7 ± 9.5 cm, body mass = 80.9 ± 13.2 kg) underwent one familiarization trial and three main conditions in a randomized order: (a) placebo (maltodextrin) and placebo, (b) caffeine and placebo, and (c) placebo and caffeine. Participants ingested either the placebo or caffeine pill 75 and 15 min before performing four quarters of the BEST and a three-point shooting protocol. During each quarter, participants completed 16 rounds of the BEST and ten three-point shots. Vertical jump height, 6 m sprint timing, BEST completion timing, three-point shooting accuracy, heart rate, rate of perceived exertion, blood glucose, blood lactate, and psychological measures pertaining to performance were measured. The BEST completion timing differed among conditions (placebo and placebo = 26.4 ± 2.0 s, caffeine and placebo = 25.8 ± 2.0 s, placebo and caffeine = 25.9 ± 2.1 s; p =.031) but not three-point shooting accuracy (placebo and placebo = 12.33 ± 4.10; caffeine and placebo = 12.61 ± 2.81; placebo and caffeine = 11.67 ± 3.77; p =.648), vertical jump height, or sprint times. Manipulating ingestion timing of caffeine did not improve three-point shooting accuracy, vertical jump height, or 6 m sprint timings, but caffeine can improve performance times during simulated basketball exercise irrespective of ingestion timing.

Context: The purpose of the study was to develop normative ranges and standards for knee and shoulder isokinetic and anthropometric values. These standards can be qualitatively interpreted and allow practitioners to classify isokinetic and anthropometric values more objectively for university-level netball players. Design: Posttest only observational study design. All players were only evaluated once during the in-season to generate normative ranges. Methods: A total of 51 female players volunteered. Participants were evaluated on an isokinetic dynamometer at 60° per second to obtain knee-extensor and knee-flexor values as well as shoulder-flexor and shoulder-extensor values. A total of 16 anthropometric variables were collected including stature, body mass, 8 skinfolds, and 6 circumferences. Between-group differences were calculated to determine whether playing level was a differentiating factor in data. Results: Normative standards were developed for isokinetic parameters associated with the knee and shoulder joints as well as skinfolds and circumference measures. No statistically significant between-group differences were evident (χKruskal-Wallis²[2] = 3.96, P = .140). Conclusion: These standards can be used by coaches and practitioners to set attainable goals for individual players or those from secondary leagues, classify individual and team-based performances, and facilitate decision-making processes.

Objective: To investigate whether transcranial direct-current stimulation (tDCS) optimizes the performance of a wheelchair basketball player on precision tasks. Methods: A right-handed wheelchair basketball player (1.5 points functional class) with myelomeningocele (low lumbar level) participated in this case study. The tDCS neuromodulation protocol was applied throughout 10 interventions of 20 minutes with a current intensity of 2 mA, simultaneously with sport-specific training, 3 times a week for 4 weeks. Anodic stimulation was performed on the right cerebellar hemisphere (CB2) and cathodic stimulation in the left dorsolateral prefrontal cortex. A control participant was submitted to a sham-tDCS stimulation protocol for the same period. Functional performance was assessed before the intervention and after the 5th and 10th interventions using "pass accuracy," "free-throw shooting," and "spot shot" tests. Outcome measures were compared using percentage differences between preintervention, intermediate intervention, and postintervention values. Results: There was a gradual increase in the athlete's total and average scores in all tests performed, with an overall improvement of 78% between the baseline and final assessments, while the control participant had an overall improvement of 6.5%. Conclusion: The tDCS protocol was effective in improving performance in precision activities in a wheelchair basketball player. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine whether subgroups of disability-sport athletes exist on morality- and norm-based doping cognitions and whether these groups differ in anticipated guilt or doping intentions. A survey was completed by 186 athletes (Mage = 37.5 years, 78.0% male, 45.1% wheelchair basketball) assessing norms, doping moral disengagement, anticipated guilt, and intentions to dope. Cluster analysis revealed four distinct subgroups of athletes, including one potentially high-risk subgroup characterized by relatively high scores on doping moral disengagement, subjective norms, and descriptive norms. One-way analysis of variance revealed significantly lower anticipated guilt in two athlete subgroups characterized by relatively higher doping moral disengagement than the other two subgroups. Moreover, the potentially high-risk group had a greater proportion of athletes showing some presence of intention to dope. This study suggests there is a small subgroup of disability-sport athletes at elevated risk of doping who might benefit from targeted antidoping interventions. [ABSTRACT FROM AUTHOR]

Purpose: We compared the adaptive responses to supramaximal high-intensity interval training (HIIT) individualized according to anaerobic speed reserve (ASR), the 30-15 Intermittent Fitness Test (VIFT), and velocity associated with maximum oxygen uptake (MAS) to determine which approach facilitates more identical adaptations across athletes with different profiles. Methods: Thirty national-level basketball players (age = 28.4 [5] y; body mass = 88.9 [6.3] kg; height = 190 [4.8] cm) were randomly assigned to 3 training groups performing 2 sets of 4, 6, 8, 6, 8, and 10-minute runs (from first to sixth week, respectively), consisting of 15-second running at Δ%20ASR (MAS + 0.2 × ASR), 95%VIFT, and 120%MAS, with 15 seconds recovery between efforts and a 3-minute relief between sets. Results: All 3 interval interventions significantly (P <.05) enhanced maximum oxygen uptake ( V ˙ O 2 max), oxygen pulse ( V ˙ O 2 / HR), first and second ventilatory threshold (VT1 and VT2), cardiac output ( Q ˙ max ), stroke volume, peak and average power output, testosterone levels, and testosterone-to-cortisol ratio following the training period. Different values of interindividual variability (coefficient of variation) for the percentage changes of the measured variables were observed in response to HIITASR, HIITvIFT, and HIITMAS for V ˙ O 2 max (8.7%, 18.8%, 34.6%, respectively), V ˙ O 2 / HR (9.5%, 15.0%, 28.6%), VT1 (9.6%, 19.6%, 34.6%), VT2 (21.8%, 32.4%, 56.7%), Q ˙ max (8.2%, 16.9%, 28.8%), stroke volume (7.9%, 15.2%, 23.5%), peak power output (20%, 22%, 37.3%), average power output (21.1%, 21.3%, 32.5%), testosterone (52.9%, 61.6%, 59.9%), and testosterone-to-cortisol ratio (55.1%, 59.5%, 57.8%). Conclusions: Supramaximal HIIT performed at Δ%20ASR resulted in more uniform physiological adaptations than HIIT interventions prescribed using VIFT or MAS. Although hormonal changes do not follow this approach, all the approaches induced an anabolic effect. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to comprehensively investigate the global implementation of flywheel training (FT) by basketball strength and conditioning (S&C) coaches in various contexts, encompassing daily practice, games, and sessions. Methods: Survey data were collected from 117 basketball S&C coaches who participated in a 24-question online survey. The survey was structured into 6 key areas, including country and competition, S&C coach context, training methodology, flywheel and competition, postactivation performance enhancement, and recovery. Results: Notably, all respondents emphasized the necessity of a familiarization period with flywheel technology, with a substantial 96% indicating that FT yielded improved player performance on the court. The predominant mention was the conical pulley system. During the season, the prevalent approach involved integrating FT into training twice a week, allocating <15 minutes per session, often in conjunction with traditional strength training. A diverse array of lower-body closed kinetic chain exercises were reported, encompassing squats, decelerations, and backward lunges. Intriguingly, FT implementation on match days was unlikely (77%), with the primary aims cited as injury prevention (34%) and enhancing players' strength levels during various phases of the regular season (27%). Conclusions: Recognizing its inherent limitations, this descriptive study provides valuable contextual insights and practical applications for professional basketball practitioners grappling with the utilization of FT.

Objectives: This study sought to report the reliability (intrasession) values of initial maximum push-rim propulsion (IMPRP) and sprint performance in elite wheelchair basketball (WB) players and to assess the involvement of strength in sprint capacity. Methods: Fifteen Spanish international WB male players participated in this study. The maximum single wheelchair push from a stationary position (IMPRP) and the sprint performance (ie, 3, 5, and 12 m) of WB players were measured in this study. Results: IMPRP mechanical outputs V, Vmax, P, Rel. P, F, and Rel. F variables presented high reliability values (intraclass correlation coefficient [ICC] ≥.92; coefficient of variation [CV] ≤ 8.04 ± 7.37; standard error of measurement [SEM] ≤ 29.92), but the maximum strength variables Pmax, Rel. Pmax, Fmax, and Rel. Fmax (ICC ≥.63; CV ≤ 13.19 ± 16.63; SEM ≤ 203.76) showed lower ICC values and by contrast higher CV and SEM values. The most substantial correlations were identified between maximum IMPRP values (ie, V, Vmax, P, Rel. P, F, and Rel. F) and sprint performance in 3 m (r ± confidence limits ≥ −0.74 ± 0.22, very large; R2 ≥.55), 5 m (r ± confidence limits ≥ −0.72 ± 0.24, very large; R2 ≥.51), and 12 m (r ± confidence limits ≥ −0.67 ± 0.27, large; R2 ≥.44). Conclusions: The IMPRP test and sprint tests (3, 5, and 12 m) are practical and reliable for measuring strength and speed in WB players. In addition, there were large to very large associations among strength variables (ie, P, Rel. P, F, and Rel. F) and all sprint variables. This could indicate a need to implement specific strength exercises in WB players to improve sprint capacity. [ABSTRACT FROM AUTHOR]

Most people with intellectual disabilities have comorbid health conditions, which will impact optimization of sporting performance. Classification is used in Paralympic events to ensure that those with similar levels of functional ability compete fairly against each other. An evidence-based approach needs to be developed for athletes with intellectual disabilities to be classified in relation to their overall functional capacity into competition groups of similar ability. This research builds on previous work using the taxonomy of The International Classification of Functioning, Disability and Health (ICF) to group athletes with intellectual disabilities into comparable competition groups as an approach to Paralympic classification. Three groups of athletes—Virtus, Special Olympics, and Down syndrome—are compared using the ICF questionnaire indicating functional health status in relation to sporting performance. The questionnaire was found to discriminate between athletes with Down syndrome and other athletes, and an approach to using a cutoff score to develop competition classes is explored.

Introduction: Obesity in adolescents is associated with reduced physical activity and athletic engagement, highlighting the need for tailored physical education programs. This study evaluated the effects of a 7-week adapted basketball program on the performance and athletic engagement of students with obesity. Methods: Sixty-two students with obesity (23 boys, 39 girls, aged 15-17) were randomly assigned to an experimental group (EG, n = 30; 11 boys, 19 girls) participating in adapted basketball sessions or a control group (CG, n = 32; 12 boys, 20 girls) attending standard basketball lessons. Both groups completed 52-minute sessions twice weekly. Pre- and post-intervention assessments included a questionnaire evaluating perceptions of physical education and athletic performance during final matches. Results: The EG showed significant improvements in interest, motivation (p < 0.05), perceived competence (p < 0.001), and reduced exercise difficulty (p < 0.001). Perceived fitness levels increased significantly only in EG girls (p = 0.013). In contrast, no significant changes were observed in the CG before and after the intervention for any of the parameters. During matches, the EG outperformed the CG, with more successful shots (girls: p = 0.0004; boys: p = 0.012), fewer missed shots (girls: p = 0.033; boys: p = 0.046), and more successful passes (p = 0.032, η ² = 0.042). Discussion: These results demonstrate that adapted physical education programs can serve as effective interventions for improving physical activity and promoting inclusion among adolescents with obesity while also serving as a preventive measure against obesity.

Background: Previous studies have shown that athletes accustomed to higher chronic workloads are less susceptible to injury than those exposed to lower chronic workloads. However, few studies have evaluated whether previous injury influences them. Therefore, this study investigated the impact of previous injuries on subsequent training loads, physical fitness, and injury rates in female youth basketball players. Methods: Training load, physical fitness, and injuries of 18 young female basketball players (age 16.8 ± 1.4 years) were monitored. Previous injury status was clustered using the K-means clustering algorithm to separate players into high-risk and low-risk groups. Linear mixed models were used to analyze the effects of previous injury status on subsequent training load and physical fitness. Meanwhile, the differences between the players' injury groups were analyzed. Results: Previous injury status can significantly impact a player's subsequent training loads, including acute loads, chronic loads, skill-based training loads, training monotony, and training strain (all p < 0.05). The two groups had no significant differences in physical fitness (all p > 0.05). Furthermore, the incidence of non-contact injuries was significantly higher in the high-risk group than low-risk group, which would result in more training time lost (all p < 0.05). Conclusion: This study identified the impact of previous injury status on subsequent training load, physical fitness, and injuries in youth female basketball players. These findings provide valuable insight for coaches to optimize training loads according to previous injury status, aiming to minimize the likelihood of subsequent injuries. [ABSTRACT FROM AUTHOR]

AbstractThis study interrogates the motivations and impacts of China’s state-sponsored political boycotting on the behaviour of multi-national corporations (MNCs). In 2016–2021, Lancome, Cathay Pacific, H&M, and the National Basketball Association (NBA) were exposed to political boycotts due to their stance on human rights and political issues in China. In these incidents, the state media’s censure and consumers’ political boycotting jointly generated a spiral of outrage. Lancome and Cathay Pacific reversed their positions in accordance with China’s demands. Conversely, H&M and NBA stood by their stance. Drawing on the four case studies, this article argues that the tug of war between China’s markets and the liberal world’s values influenced an MNC response. It contributes to the political consumerism literature in three ways. First, it examines political consumerism in non-democratic contexts. Second, it offers nuances of political boycotts by pinpointing the dynamics between the state’s mobilisation and consumers’ motivation. Third, it underlines the conditions that make MNCs susceptible to political boycotts. Meanwhile, the article also speaks to the economic statecraft literature. Political boycotting is an underexplored instrument in China’s economic statecraft. By pressuring MNCs to conform to the Chinese rules, state-sponsored political boycotts gradually contest norms in the liberal international order. [ABSTRACT FROM AUTHOR]

The study aimed to analyse and comprehend the variability in training load periodisation among elite basketball coaches, identifying specific strategies employed during different stages preceding matches. The external workload was monitored during the three practices prior to the first match of the week using wearable microtechnology over six seasons (2016–17 to 2021–22). Eight variables were collected for analysis during all sessions and across the six coaches: total duration, Player Load (PL), accelerations (ACC), decelerations (DEC) and number of JUMPS in both total (t) and high intensity bands (h). The study revealed significant variations in training load variables across pre-match sessions, with MD-1 showing distinct differences compared to MD-3 and MD-2. Coaches exhibited diverse approaches in managing external load variables, particularly evident in MD-3 where Co1 imposed the lowest load and Co3 the highest. Results showed significant variability in training load variables across pre-match sessions, with MD-1 exhibiting distinct differences compared to MD-3 and MD-2. Significant variability was observed among coaches for each MD. While there was a general trend that all coaches followed to some extent, each coach still had their unique methods or strategies, and these differences were most apparent during the MD-3.

Economic research on racial discrimination frequently employs data from sports. We analyze admission decisions for the Naismith Basketball Hall of Fame (HOF) for evidence of discrimination against Black National Basketball Association (NBA) players from the 1950s to the 2010s. Our results suggest that, holding career performance constant, the average Black former All-Star, who is not currently in the HOF, is about five percentage points less likely to be admitted into the HOF compared to similar non-Black All-Stars. This represents about a 50% reduction in the probability of admission into the HOF. The anonymous electors to the HOF appear to act on discriminatory preferences. Like the results in the NBA salary discrimination literature, this effect disappeared in the 1980s and 1990s and reappeared in the 2000s. [ABSTRACT FROM AUTHOR]

Timeouts are a widely supported strategy in the literature, recognized for directly influencing team performance during basketball games. This study aimed to analyze and define the successful patterns of actions after timeouts (ATOs) during critical moments in the 2022/23 EuroLeague season. The sample was drawn from the last two minutes and overtime of 169 games with a final point difference of 10 points or fewer, totaling 365 ATOs. An observational methodology was used, applying the LINCE PLUS software version 2.1.0 and an ad hoc observational instrument. Descriptive analysis and chi-square tests (χ2) were conducted using SPSS 25.0, and T-pattern analysis was performed with Theme 6 software. Statistical significance was set at p < 0.05. Teams in the lead often concluded successful plays through free throws following opponent fouls, while teams trailing behind attempted to close the gap by committing fouls to force free throws in defense and scoring two-point baskets on offense. The findings offer insights into ATOs strategies that can support coaches and technical staff in training and adapting these actions to meet competition demands during critical game moments. These results may assist in enhancing team performance and decision-making under high-stakes conditions. [ABSTRACT FROM AUTHOR]

Objectives: This study describes the effects of patellar fracture on return to play (RTP) and functional outcomes among athletes in American professional sports. Methods: Professional athletes from the National Football League (NFL), National Basketball Association (NBA), Major League Baseball (MLB), and National Hockey League (NHL) who suffered a patellar fracture between January 1965 and December 2021 were identified through injury reports and public archives. Performance scores, play time, and games played were collected for the season preceding patellar fracture and 2 seasons after RTP, and differences in recorded metrics compared to pre-injury levels and matched controls were analyzed. Results: Twenty-nine of 41 (71%) injured athletes returned to play at an average of 217 days. Among all players, play volume decreased in year 1 compared to baseline but recovered to pre-injury levels in year 2. Athletes treated operatively experienced an initial decline in performance (p < 0.01) but recovered to pre-injury performance level in year 2. Nonoperative management resulted in a decline in performance in year 2 of RTP (p = 0.02). Athletes treated operatively performed significantly worse than matched controls in year 1 of RTP (64% vs. 99%; p = 0.04) but recovered to a similar level of performance as controls in year 2 (87% vs. 91%; p = 0.90). Conclusion: A 71% rate of RTP was demonstrated among this limited cohort of 29 athletes in American professional sports after isolated patellar fracture. Although details regarding fracture characteristics and operative reports were not available for analysis, operative management was not associated with longer absence from play compared to nonoperative treatment. Despite the limitations of this study, the findings suggesting operative management may improve prospects of maintaining elite performance following RTP warrant further investigation. Level of evidence: Case-control cohort analysis; Level of evidence, 3. [ABSTRACT FROM AUTHOR]

When considering that athletes are becoming more vocal about their beliefs related to social justice initiatives, the role of an athlete's gender could have an impact on how sports fans view that athlete. When deciding to support or oppose a corporate social advocacy initiative, it can be argued that an individual's perception of an athlete's or team's stance towards social justice can be influenced by elements of one's social identity. Therefore, the current study expands on this idea by exploring how gender affects the perception of the credibility of an athlete as an endorser of CSA initiatives, considering both the gender of the participant and the gender of the athlete. Using both NBA and WNBA athletes, this experiment manipulates a league CSA initiative and players' endorsements of the initiative to determine if (a) the participant's reported gender and (b) the athlete's gender will impact the perception of the athlete's credibility. Results provided evidence that gender plays a significant role in that evaluation, such that the NBA player was perceived as more credible regardless of respondent gender, and while female respondents recorded no difference, male participants perceived the NBA player as more credible than his WNBA counterpart.

Introduction: This study aims to investigate age-related differences in physical performance metrics, specifically vertical jumping and sprinting capabilities, between young (average age 12.5) and senior (average age 23.2) male basketball players. Methods: Performance metrics were assessed through standardised tests measuring jump height and sprint times, alongside force production during eccentric and concentric phases of jumping movement. Results: Key findings show that senior players outperform younger athletes in both sprint times and jump heights, attributed to greater physical maturation and neuromuscular development. However, contraction times and phase durations were similar across both age groups, indicating that strength improvements do not affect fundamental movement timing. Discussion: These results highlight the importance of age-specific training programs that focus on developing explosive power for younger players and optimising performance while minimising injury risk for seniors. The study provides valuable insights and recommendations for tailoring training strategies to athletes' developmental stages and suggests that further research is needed to explore effective interventions for enhancing physical performance across the lifespan.

Objective: This study aimed to evaluate the effectiveness of combining basketball training with a traditional sensory integration therapy (SIT) vs. a SIT alone in enhancing sensory integration capability among Chinese children diagnosed with mild challenges in sensory integration and sensory processing (CSISP). Methods: This study comprised a Control group and an Experimental group, both undergoing a 10-week intervention (4 sessions/week, 45 min/session). The Control group exclusively participated in traditional SIT for all sessions. In contrast, the Experimental group engaged in traditional SIT for two sessions per week and Basketball training for the remaining two sessions weekly. Three sensory integration measures (vestibular sensation, tactile perception, proprioception) and five gross motor performance measures (balance beam walking speed, single-leg standing with eyes closed, tennis ball throw, two-legged jump speed, 10-m shuttle run) were assessed before and after the 10-week training period. Separate 2 (Group) × 2 (Test Phases) Analysis of Variance (ANOVA) with repeated measures on the second factor were conducted for each measure. Interaction effects were further explored using Tukey's HSD test to clarify their nature. Results: Both groups demonstrated significant improvements in all sensory integration and gross motor performance measures following the 10-week training sessions (p < 0.001). Importantly, the group receiving the combination of basketball training and traditional SIT significantly outperformed the group undergoing SIT alone in all assessed areas. Conclusion: These results indicate that combining basketball training with traditional SIT enhances sensory integration capabilities more effectively among Chinese children aged 4–6 years with moderate CSISP compared to utilizing SIT alone.

Study Design.: Systematic review. Objective.: The primary purpose of this article was to survey the present literature and report on return-to-play (RTP) outcomes in elite athletes after undergoing motion preservation spinal surgery (MPSS). Background.: For elite performance, athletes require adequate mobility throughout the trunk, torso, and spine to achieve maximal force production. Therefore, elite athletes who have failed conservative treatment may seek to undergo motion-preserving surgical options, such as total disc arthroplasty and lumbar microdiscectomy. Individual studies have reported on RTP outcomes following individual motion preservation surgical procedures, but no systematic reviews have formally reported on RTP outcomes, postoperative performance, and reoperation rates on these procedures in elite athletes. Materials and Methods.: A systematic review was conducted from inception until February 2024 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. One reviewer queried PubMed for relevant studies that reported on RTP outcomes in elite athletes after MPSS based on title and abstract (n = 1404). After the original search query, an additional reviewer screened full-length articles. A total of 11 studies met the inclusion criteria. Special consideration was given to RTP rates, postoperative performance, and reoperation rates. Results.: A total of 612 elite athletes from the National Basketball Association, Major League Baseball, National Football League, National Hockey League, and other professional sporting organizations underwent cervical and lumbar MPSS to treat various spinal pathologies. Various motion-sparing techniques were used to treat various pathologies. After undergoing MPSS, RTP rates ranged from 75% to 100% for lumbar cases and 83.3% to 100% for cervical cases. Postoperative performance varied with some athletes performing at the same level before surgery and some performing at a decreased level. Conclusions.: MPSS is a feasible option when properly indicated. Future studies are needed to compare return to sport rates, postoperative performance, and reoperation rates between MPSS to spinal arthrodesis. [ABSTRACT FROM AUTHOR]

The aim of this study was to understand and describe the physiological and biomechanical demands of various tasks used in basketball training and, subsequently, to provide a practical application of these tasks in a typical training week. Twelve basketball players had their external load variables monitored across 179 training sessions (2896 samples) using local positioning system technology. These variables included total distance covered, distance covered at various intensity levels, accelerations, decelerations, PlayerLoad™, and explosive efforts. The analysis revealed significant differences in both physiological and biomechanical loads across various drills. Specifically, tasks with more space and fewer defenders, such as 3v0 full court, impose higher physiological loads compared to tasks with less space and more defenders, like 5v5 full court. The difference in physiological load between these tasks was statistically significant (p < 0.05) with a moderate effect size (ES: −0.60, 95% CI: [−0.99, −0.22]). In terms of biomechanical load, drills with increased defensive pressure, such as 5v5 full court, exhibited significantly higher values compared to less specific drills, such as 5v0 full court, with a very large effect size (ES: 1.37, 95% CI: [1.04, 1.70], p < 0.01). Additionally, comparisons between 5v5 full court and 3v0 full court for biomechanical load produced a very large effect size (ES: 1.67, 95% CI: [1.37, 1.97], p < 0.01), indicating a substantial difference in load demands. The results indicate that tasks with more space and fewer defenders impose higher physiological loads, while those with less space and more defenders increase the biomechanical load. For training design, it is recommended to schedule tasks with a higher biomechanical load at the beginning of the session and those with a physiological orientation toward the end. Understanding the distinct demands of different drills can help coaches structure training sessions more effectively to optimize player load and performance development throughout the week.

Background: Regular epidemiological investigations are needed to investigate factors associated with low back injuries (LBIs) in National Collegiate Athletic Association (NCAA) sports and to inform injury prevention and rehabilitation. Purpose: To describe the epidemiology of LBIs in NCAA sports. Study Design: Descriptive epidemiology study. Methods: Exposure and LBI data collected in the NCAA Injury Surveillance Program during the 2009-10 through 2018-19 academic years were analyzed. Injury counts, rates, and proportions were described by sport, sex, event type (competition, practice), season segment, time loss (>1 day), history (recurrent, new), chronicity, injury mechanism, diagnosis, and activity. Injury rate ratios (IRRs) were used to evaluate differential injury rates, and injury proportion ratios (IPRs) were used to assess differential injury distributions. Effect estimates (IRRs, IPRs) with 95% CIs excluding 1.0 were deemed statistically significant. Results: During the study period, 2629 LBIs from 12,213,285 athlete-exposures (AEs) were reported to the NCAA Injury Surveillance Program (2.15 LBIs per 10,000 AEs). Rates were highest in women's gymnastics (5.39 per 10,000 AEs), men's tennis (3.39 per 10,000 AEs), and women's volleyball (3.38 per 10,000 AEs). Among sex-comparable sports, rates were higher in men's (compared with women's) basketball and cross country. Competition injury rates were >2 times as high as practice rates in men's sports; no difference was found in injury rates by event type in women's sports. Chronic LBIs were more prevalent in women's sports (compared with men's) (IPR = 1.51; 95% CI, 1.29-1.76), as were recurrent injuries (IPR = 1.24; 95% CI, 1.05-1.46). Conclusion: Overall, LBI rates were similar in men's sports and women's sports; injuries were most often attributed to noncontact and overuse. LBI rates across event type varied by sport, with notable differences in women's sports. Future research into LBI risk factors and prevention programs that emphasize proper technique, training, and recovery, especially in practice settings, could be beneficial to reducing the burden of lumbar spine injuries in NCAA athletes.

Background: Current research relates jaw clenching to athletic performance, in terms of force and agility. However, the impact of jaw clenching on sports accuracy is unclear. Objectives: To analyse the impact of jaw position and chewing type on free‐throw accuracy and electromyographic (EMG) activity of masticatory muscles during free‐throws. Methods: Cross‐sectional study with 25 female basketball players aged 18–44. Each participant executed 18 free‐throws under three different jaw conditions: mandibular rest, maximum intercuspation, and with interdental cotton rolls, in randomised order. Results: Chewing type and jaw position were not associated with shooting accuracy (p = 0.106; p = 0.778). There was a positive correlation between EMG activity of the right masseter and free‐throw accuracy at maximum intercuspation (rs = 0.402; p = 0.046). In contrast, negative correlations were found with other muscles when the occlusal vertical dimension was altered (rs = −0.619, p = 0.001; rs = −0.490; p = 0.013; rs = −0.534; p = 0.006). The chewing type affected the EMG of the left masseter in the altered occlusal vertical dimension (H = 6.969; p = 0.031). Significant differences in EMG recordings were observed across different mandibular positions during free‐throws (p < 0.001). Conclusions: While jaw positioning and chewing type do not impact free‐throw accuracy in amateur female basketball players, the EMG activity of masticatory muscles is linked to shooting performance. This highlights the need for further research on motor behaviour of masticatory muscles in precision sports, especially for athletes using intraoral devices. [ABSTRACT FROM AUTHOR]

The intricacies of our world often lead to nuanced data, which has significant implications for data analysis. Data analysts must be wary of moving too quickly to final conclusions. Behind an insight might lurk initially misleading results. In the context of sports analytics, specifically basketball, this article demonstrates the intrinsic need for the sports analyst to pose a question and then prod and investigate the insights offered by the data. The article analyzes public datasets with less than a dozen data points and more than 400,000 rows of data. Further, the article offers an entryway to the field of data analytics via sports.

The aim of the study was to determine whether acute changes in neuromuscular performance can be detected through countermovement jumps (CMJs) conducted pre- and postpractice sessions in conditions of high or low intensity measured by microsensors technology. Using an observational repeated measures design, data were collected from 10 male collegiate basketball players. Countermovement jump data were collected before and after practice exposures over 4 weeks of preseason. Select CMJ kinetics were compared in conditions of high and low training load intensity to detect neuromuscular performance changes in displacement of the center of mass and kinetics. Kinetic measures were categorized as output, underpinning, and strategy-related variables. We investigated "output" defined as displacement (jump height [JH]), "underpinning" defined as force-related (mean eccentric force, mean concentric force, force at zero velocity), and "strategy" defined as time-related (countermovement depth [CMD], eccentric duration (EccDur), concentric duration [ConcDur]) variables. There were significant condition3time interactions in CMJ variables namely eccentric mean force (EccForce), force at zero velocity (Force@0), CMDepth, EccDur, and ConcDur. In conditions of high intensity, players had significant, but small decreases in EccForce and Force@0, with small increases in CMD, EccDur, and ConDur, respectively. However, there were no significant decreases in JH. High-intensity practice exposures did not impact neuromuscular performance specific to "output," suggesting that collegiate basketball athletes can maintain JH despite alterations in "underpinning" and "strategy-related" variables. This could have relevance in understanding how fatigue associated with higher-intensity training exposures may potentially alter jump strategy and force production capacities due to external load intensity in collegiate basketball athletes.

This study investigated the effects of half-time re-warm-up (RW) comprising core strength exercise (CSE) on basketball players' subsequent power and change of direction (COD) performance. Twelve male collegiate basketball players were recruited to perform 3 conditions--CSE RW on a stable platform (STA) or an unstable platform (USTA) and passive rest (control, CON)--in randomized, counter-balanced order after a modified Loughborough intermittent shuttle test (LIST). The COD and power performance tests were administered before the LIST and after the interventions. Heart rate (HR) was continuously measured during each trial. Results showed significantly lower changes in T-test time in STA compared with CON (p, 0.05). Changes in countermovement jump height in STA were significantly higher than those in CON (p, 0.05). During the isometric midthigh pull test, changes in the maximum rate of force development (RFD) (p,0.05), RFD in the range of 0-90 milliseconds (p,0.05), 0-150 milliseconds (p,0.05), 0-200 milliseconds (p, 0.05), and 0-250 milliseconds (p, 0.05), in STA were significantly higher than those in CON. In addition, RFD in the range of 0-150 milliseconds (p, 0.05) and 0-250 milliseconds (p, 0.05) in USTA was significantly higher than that in CON. The mean HR during USTA was significantly higher than that in STA and CON (p, 0.05). These findings indicated that CSE RW during halftime might prevent power and COD performance decline in the second half of a game, with practical implications for coaches and players.

Background: The foam roller is considered a versatile tool. Along with an active warm-up, it appears to positively affect range of motion, stability, muscle stiffness, and perceived exertion with no reductions in performance. Hypothesis/Purpose: The main purpose of the study was to observe the effects of the utilization of a foam roller during the warm-up on ankle mobility and lower limb stability, and secondarily, to assess if any induced effects were sustained over time. Study design: Randomized controlled trial. Methods: Twenty-two healthy male subjects were randomly assigned to two groups: the control group, which only carried out a general warm-up over a period of four months, and the foam roller group, which followed a specific warm-up routine using a foam roller for a period of three months plus one month of follow-up in which no foam rolling was performed. Two outcome measurements were taken pre- and post- intervention to assess ankle mobility: the Dorsi-Flexion Lunge test and the Y-Balance test (YBT) for the lower quarter. Outcomes were measured at three time points: before the protocol was initiated, at the end of the protocol (at 12 weeks), and after a one-month follow-up period (at 16 weeks). Results: A significant increase was observed in the dorsiflexion of the right (p < 0.001) and left (p < 0.001) ankles in the experimental group. Significant increases were also noticed in the anterior (p < 0.003), posteromedial (p < 0.050), and posterolateral (p < 0.050) reach distances of the right leg and in the anterior (p < 0.002), posteromedial (p < 0.010), and posterolateral (p < 0.030) reach distances of the left leg during the YBT in the experimental group. The control group also showed significant differences in the right (p < 0.007) and left (p < 0.010) anterior reach distances on the YBT. At the one-month follow-up period, the improvements that had been obtained in both groups were lost, except for the dorsiflexion of the right ankle (p < 0.050) and right (p < 0.010) and left (p < 0.030) anterior reach distance on the YBT in the experimental group. Conclusions: The foam roller can be used as a part of a pre-training warm-up routine to enhance the dorsiflexion range of motion and performance on the YBT. Level of Evidence: 3.
