Acute effects of static stretching (SS) and proprioceptive neuromuscular facilitation (PNF) on local and non-local range of motion (ROM) were assessed in 29 participants. Three evaluations were performed one week apart: week-1 Control session (CS); weeks 2–3 either SS or PNF interventions (randomized). Dominant and non-dominant limbs, local (hamstring extensibility) and non-local ROMs (Shoulder extension-ShE) were collected at baseline (T0), immediately after (T1), and fifteen minutes post-intervention (T2). No differences were found between time-points during the CS. Local-ROM significantly increased (p=0.0002, ES=0.74 and 0.0079, 0.56, for dominant and non-dominant lower limbs, respectively) after both SS and PNF. No interaction between time and treatment was detected for ShE in both limbs. However, post-hoc analysis revealed a significant increase in dominant upper limb ShE between T0 and T1 only after SS (p=0.002; +6.5%). Acute bouts of SS and PNF can increase local-ROM, however, no clear effects were observed for non-local ROM. [ABSTRACT FROM AUTHOR]

Introduction: While pedaling, cyclists rest their pelvis on the saddle, generating pressures on it. The pressures generated on the saddle are influenced by several factors. This study aimed to evaluate whether the flexibility of hamstring and lower back muscles could be considered a predictor of pressures in the anterior region (PAR) on the saddle. Methods: For this study, 15 young off-road Italian cyclists (11m, 4f) aged 13–16 (Italian Federation categories: ES1, ES2, AL1, AL2) were recruited. Each participant was administered the V sit-and-reach (VSR) to measure the hamstring and lower back muscles flexibility. Subsequently, after performing a bike fitting, the saddle pressures during pedaling at three different intensities (100, 140, 180 W), with participants on their own bike installed on specific bike roller, were recorded. The parameters considered for statistical analysis were front pressure (%) and back pressure (%). Results: The hamstring and lower back muscles flexibility, as result of the VSR test, was a predictor of saddle PAR at 100 W (R² = 0.362, p = 0.018), at 140 W (R2 = 0.291, p = 0.038), and at 180 W (R² = 0.349, p = 0.020) of pedaling intensity. Conclusion: Higher values of the VSR could predict lower values of the pressures exerted in the front region of the saddle. The hamstring and lower back muscles flexibility may be considered a predictor of PAR on the saddle. [ABSTRACT FROM AUTHOR]

Practicing physical activities or sports that involve frequent jumping and landing can strain the muscles and joints of the lower limbs, especially in those who do not have adequate physical preparation. The objective of this study was to (a) determine the correlation between ankle range of motion (ROM) and landing stability following jumps; (b) assess the association between the jump height in a counter-movement jump (CMJ) test and ankle ROM; and (c) examine the connection between stabilometry during specific jumps movements present in many sports and in ankle stabilization. Sixty-two healthy amateur volleyball players participated in the study (age: thirty-seven females and twenty-five males; age (years): 16.5 ± 4.25; height (cm): 166 ± 11.4; weight (Kg): 61.6 ± 13.7). Participants were recruited for the study in collaboration with student sports associations. The evaluations encompassed the measurement of ankle joint mobility for both lower limbs using an inertial sensor, a static baropodometric and stabilometric analysis using a pressure platform, and the CMJ test using the Microgate system. After the assessments, participants performed a "specific jump landing task". Significant correlations were found between foot range of motion (ROM) and counter-movement jump (CMJ) performance. Specifically, the ROM of the right foot had a strong correlation with the CMJ (r = 0.81, p < 0.001), while the left foot ROM showed a moderate correlation (r = 0.46, p < 0.001). The specific jump task revealed substantial changes in stabilometry parameters, particularly during forward hops compared to lateral jumps. Dorsiflexion ROM significantly impacts jumping ability. Evaluating landing patterns and stabilometry during targeted activities can help optimize training, improve dynamic balance, and reduce ankle injury risk. [ABSTRACT FROM AUTHOR]

Background: The movement of the barbell has been detected as success factor for the snatch and the clean and jerk events. As the barbell's movement has been shown to be related to the athlete's body movement, we hypothesized that the latter could be a success factor also for the back squat (BS) event. Hence, this study aimed to investigate postural control during the execution of the BS at different load intensities in powerlifters and weightlifters. Methods: Seventeen powerlifters and weightlifters were enrolled and the one-repetition maximum (1-RM) of the BS of each participant was measured. Afterwards, the assessment of postural control during the execution of the BS at different load intensities (i.e. 60%, 70%, 80%, 90%, 100%) of the 1-RM of each participant was carried out through a posturographic platform to measure the displacement of the centre of pressure (CoP). The following parameters were considered: sway path length (SPL), sway ellipse surface (SES), length/surface (LFS ratio), sway mean speed (SMS), CoP coordinates along X and Y planes. Results: We found a significant increase in SPL and LFS ratio, and a significant decrease in SMS as the load intensity increased. In detail, we detected a significant difference in: (a) SPL between the BS at 60% and 80%, 60% and 90%, 60% and 100%; between the BS at 70% and 90%, 70% and 100%; between the BS at 80% and 100%; and between the BS at 90% and 100%; (b) SMS between the BS at 60% and 80%, 60% and 90%; (c) LFS ratio between the BS at 60% and 90%, 60% and 100%. Conclusions: These results suggest that powerlifters and weightlifters adopt different postural control strategies depending on the load intensity when performing the BS. Our findings showed that higher effort could affect postural control during the BS. Thus, postural control could be considered a success factor for the BS. [ABSTRACT FROM AUTHOR]

Low back pain is the most frequently reported musculoskeletal disorder and represents one of the highest patient burdens in healthcare. This systematic review and meta-analysis aimed to investigate the effectiveness of Pilates exercise on pain intensity and functional disability caused by low back pain (LBP). A Systematic review with meta-analysis was conducted. Data sources: MEDLINE-NLM and MEDLINE-EBSCO. We also searched on Scopus Elsevier, Cochrane, DOAJ, SciELO, PEDro, and PLOS ONE databases. Eligibility criteria: randomized controlled trials (RCTs) evaluating LBP in which the primary treatment was based on Pilates exercise compared with no exercise, or non-specific exercise. The search returned 1566 records of which 36 articles were included in the systematic review and 19 in the meta-analysis. Twenty-two studies compared the effects of Pilates exercise vs no exercise and 13 studies examined the effects of Pilates exercise vs non-specific exercise. Analysis showed that Pilates had a positive effect on the perception of LBP vs no exercise. A similar trend occurred with non-specific exercise. Pilates exercise can decrease LBP compared to no exercise and non-specific exercise. General practitioners should consider Pilates exercise as an effective strategy to manage LBP and counteract the growing health. PROSPERO registration number: CRD42022308387. Pilates is a good strategy for improving low back pain and is more effective than other exercise programs or no exercise. Pilates is a safe tool to apply to most of the population with low back pain. Pilates is a non-pharmacological strategy useful for counteracting low back pain. [ABSTRACT FROM AUTHOR]

To investigate differences in the game demands of top-level professional basketball players based on their position and the quarter of the game. Thirteen elite male players were assessed on their positions (point guard, guard, forward, and centre) over different quarters (Q1-Q4) during 15 home games. A multivariate analysis of variance was performed using role and quarters as predictors to assess distances, speeds, and accelerations. The guard and point guard covered more distance than the centre and forwards (p > 0.001). The average distance covered was higher (p < 0.01) in Q4 than in the other quarters. Both speed and the percentage of time spent in the jogging to max speed range decreased significantly from Q1 to Q4, while time spent standing and walking tended to increase from Q1 to Q4. The point guard spent the highest percentage of total time performing major accelerations followed by the guard, while the forwards and centre spent less time performing accelerations. Overall, 22.8 ± 0.7% of total playing time was spent performing major accelerations, which decreased from Q1 to Q4. These findings suggest that the positions of elite basketball players vary in terms of the activities demands they place on players, underscoring the need for individualised role-based conditioning.

Background: Padel has spread rapidly in several countries around the world. Although this racket sport seems to have several health benefits, the number of scientific papers on this sport is still very few. This scoping review aimed to systematically map the evidence regarding injuries in Padel players by identifying, synthesizing, and assessing the studies currently existing in the scientific literature. Methods: This scoping review was conducted following the guidelines provided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews and the Population, Concept, Context framework was adopted. Articles were collected from PubMed, Web of Science, and Scopus. Results: A total of seven studies were included in this review. The most frequent injury location is in the elbow, followed by shoulder, and low back. As for lower limbs, knee represents the most affected body region. Although not all the studies included described the type of injuries, tendon, joint, and muscle are the body structure most injured. Conclusion: This scoping review can aid in a better comprehension of the location and type of injuries that occur in Padel players. However, it is worth noting that all the studies existing concerns nonprofessional athletes. Hence, these findings could be useful to coaches as they add knowledge on the risk of injury in padel that can allow the planning of suitable training programs for amateur and recreational players in order to prevent injuries.
