Pre-professional identity (PPI) aims to provide an understanding of, and connection to, the skills and knowledge contained in a degree and the intended profession of the student. Investigation into PPI is of importance to higher-education institutions as it provides a means of understanding a student's orientation and motivation behind degree and career selection. Developing learning activities that capitalise on these motivations is proposed to increase student engagement, reduce attrition, and enhance employability. Using the growing, but relatively new profession of Exercise Science as an example, this study describes a workshop based on theoretical models relating to the concept of PPI, adult learning and self-reflective practices that can be integrated into programs to enhance students' understanding of their professional identity. One hundred and seventy-three final year Exercise Science students participated in and evaluated the workshop. The workshop was evaluated using a theoretical framework specifically designed for the evaluation of training activities. The combination of the evaluation and feedback from students were synthesised to develop a model for the application of PPI activities across a three-year undergraduate degree.

Purpose: To determine whether menstrual-cycle symptoms are associated with sleep in elite female athletes. Methods: Sleep was assessed for a minimum of 25 nights (range = 25–31) using activity monitoring and sleep diaries. Menstrual-cycle symptoms were collected over the same duration in 12 elite female professional soccer players. Generalized estimating equations were used to examine the relationship between the day of the menstrual cycle (from day 1) and total menstrual-cycle symptoms on sleep characteristics. Results: There was a significant relationship between sleep duration and the day of the menstrual cycle (P =.042) and total symptoms reported that day (P <.001), with sleep duration increasing by 21 minutes for every symptom reported. There was a negative day × symptom interaction on sleep duration (P =.004), indicating that with increased symptoms, the day of the menstrual cycle had a smaller relationship with sleep duration. Sleep efficiency (P =.950), wake after sleep onset (P =.217), and subjective sleep quality (P =.080) were not related to the day of the menstrual cycle. The total symptoms reported had no relationship with sleep efficiency (P =.220), subjective sleep quality (P =.502), or sleep latency (P =.740) but did significantly relate to wake after sleep onset (P <.001), with a significant day × symptom interaction (P <.001). Conclusions: Sleep duration increased from day 1 of the menstrual cycle and was associated with the number of menstrual-cycle symptoms reported. All other sleep metrics remained unchanged; however, total symptoms reported were related to wake after sleep onset. Monitoring and managing menstrual-cycle symptoms should be encouraged due to a potential relationship with sleep characteristics. [ABSTRACT FROM AUTHOR]

The cyclical changes in sex hormones across the menstrual cycle (MC) are associated with various biological changes that may alter resting metabolic rate (RMR) and body composition estimates. Hormonal contraceptive (HC) use must also be considered given their impact on endogenous sex hormone concentrations and synchronous exogenous profiles. The purpose of this study was to determine if RMR and dual-energy X-ray absorptiometry body composition estimates change across the MC and differ compared with HC users. This was accomplished during a 5-week training camp involving naturally cycling athletes (n = 11) and HC users (n = 7 subdermal progestin implant, n = 4 combined monophasic oral contraceptive pill, n = 1 injection) from the National Rugby League Indigenous Women's Academy. MC phase was retrospectively confirmed via serum estradiol and progesterone concentrations and a positive ovulation test. HC users had serum estradiol and progesterone concentrations assessed at the time point of testing. Results were analyzed using general linear mixed model. There was no effect of MC phase on absolute RMR (p =.877), relative RMR (p =.957), or dual-energy X-ray absorptiometry body composition estimates (p >.05). There was no effect of HC use on absolute RMR (p =.069), relative RMR (p =.679), or fat mass estimates (p =.766), but HC users had a greater fat-free mass and lean body mass than naturally cycling athletes (p =.028). Our findings suggest that RMR and dual-energy X-ray absorptiometry body composition estimates do not significantly differ due to changes in sex hormones in a group of athletes, and measurements can be compared between MC phases or with HC usage without variations in sex hormones causing additional noise.

Pre-professional identity (PPI) is an understanding of the skills, qualities, conduct, culture and ideology of a students' intended profession. Understanding PPI is valuable for students and higher-education providers to provide insight into motivation for- and to promote engagement in- learning. Describing PPI is challenging, particularly for evolving health professions. This paper describes a process undertaken to understand PPI, using exercise science (ES), a new and evolving health profession, as a case study. Mixed methods were used to describe three aspects of PPI: 1) student cohort characteristics; 2) personal factors influencing PPI; and 3) perceived career direction. Final year ES students participated in an online survey and a focus group (n=305; 59% male; 75% age range of 20-24 years). Factors contributing to the development of PPI included the desire to help others; interest and experience in sports/exercise. Students had the strongest understanding of the PI domains of affiliation, money and structure and limited understanding of the role of scientist and researcher. Two outcomes were derived from the study findings to advance the theoretical understanding of PPI: 1) a 3-item framework that describes factors specific to students' PPI; and 2) a worked case study demonstrating how this framework was applied to gain a nuanced understanding of PPI in ES. Our framework can be applied to increase student and higher education providers understanding of PPI and the motivations underpinning student decision-making in higher education.

We examined performance across one menstrual cycle (MC) and 3 weeks of hormonal contraceptives (HC) use to identify whether known fluctuations in estrogen and progesterone/progestin are associated with functional performance changes. National Rugby League Indigenous Women's Academy athletes [n = 11 naturally menstruating (NM), n = 13 using HC] completed performance tests [countermovement jump (CMJ), squat jump (SJ), isometric mid‐thigh pull, 20 m sprint, power pass and Stroop test] during three phases of a MC or three weeks of HC usage, confirmed through ovulation tests alongside serum estrogen and progesterone concentrations. MC phase or HC use did not influence jump height, peak force, sprint time, distance thrown or Stroop effect. However, there were small variations in kinetic and kinematic CMJ/SJ outputs. NM athletes produced greater mean concentric power in MC phase four than one [+0.41 W·kg−1 (+16.8%), p = 0.021] during the CMJ, alongside greater impulse at 50 ms at phase one than four [+1.7 N·s (+4.7%), p = 0.031] during the SJ, without differences between tests for HC users. Among NM athletes, estradiol negatively correlated with mean velocity and power (r = −0.44 to −0.50, p < 0.047), progesterone positively correlated with contraction time (r = 0.45, p = 0.045), and both negatively correlated with the rate of force development and impulse (r = −0.45 to −0.64, p < 0.043) during the SJ. During the CMJ, estradiol positively correlated to 200 ms impulse (r = 0.45, p = 0.049) and progesterone to mean power (r = 0.51, p = 0.021). Evidence of changes in testing performance across a MC, or during active HC use, is insufficient to justify "phase‐based testing"; however, kinetic or kinematic outputs may be altered in NM athletes. Highlights: Evidence of changes in testing performance across a menstrual cycle, or during active hormonal contraceptives use, is insufficient to justify "phase‐based testing" at a group or team‐based level among female rugby league athletes.Kinetic or kinematic outputs in jumping movements may be altered in naturally menstruating athletes; however it could not be determined if the observed alterations exceeded between‐day variability.

Purpose: The aim of this systematic review was to (1) determine the muscle fiber-type composition (or muscle fiber typology [MFT]) of team-sport athletes and (2) examine associations between MFT and the physical characteristics and performance tasks in team-sport athletes. Methods: Searches were conducted across numerous databases—PubMed, SPORTDiscus, MEDLINE, and Google Scholar—using consistent search terms. Studies were included if they examined the MFT of team-sport athletes. Included studies underwent critical appraisal using the McMasters University critical appraisal tool for quantitative research. Results: A total of 10 studies were included in the present review, wherein the MFT of athletes was measured from 5 different team sports (soccer, rugby union, rugby league, handball, and volleyball). There was large variability in the MFT of team-sport athletes both within (up to 27.5%) and between sports (24.0% relative difference). Male football players with a higher proportion of type II fibers had faster 10- and 30-m sprint times, achieved a greater total distance sprinting (distance at >6.67 m·s−1), and a greater peak 1-minute sprint distance. Conclusions: MFT varies considerably between athletes both within and between different team sports. The results from some studies suggest that variation in MFT is associated with high-intensity running performance in a football match, as well as 10- and 30-m sprint times. Further experimental studies should focus on how determination of the MFT of team-sport athletes could be utilized to influence talent identification, team selection, and the individualization of training.

Sport psychology consulting services are commonly used by elite athletes in developed countries, but little is known about the athlete's perceptions of such services in developing countries. The present study examined the accessibility, receptivity, and perceived benefit of sport psychology services (via a sport psychology services questionnaire) through a cross-sectional survey of elite athletes (N = 32; M age = 23.06 years, SD = 5.81) from 12 nations of the Oceania region who participated in the Gather, Adjust, Prepare, Sustain programme. These nations were Vanuatu, Fiji, Tuvalu, Tonga, Solomon Islands, Cook Islands, Norfolk Island, Niue, Nauru, Kiribati, Samoa, and Papua New Guinea. The results revealed that only a quarter of the athletes had ongoing access to sport psychology consulting services. Over half reported that they were receptive to sport psychology services and perceived that these types of services would be beneficial. The most desired services related to performance enhancement (e.g. performance under pressure). The athletes reported mixed levels of knowledge regarding mental skills, and most knowledge concerned the use of mental skills in competition. Specifically, most athletes rated their knowledge of mental skills at either the low (e.g. imagery) or high (e.g. goal setting, focus, and self-talk) range, and relatively fewer athletes rated their knowledge in the mid-range. The athletes demonstrated interest in learning more mental skills to enhance their performance. These findings indicate that a need exists for sport psychology service providers among athletes in the Oceania region. Existing non-local providers may also consider supplying services through digital modalities. [ABSTRACT FROM AUTHOR]

Purpose: To examine whether the muscle typology of elite and world-class swimmers could discriminate between their best distance event, swimming stroke style, or performance level. Methodology: The muscle carnosine content of 43 male (860 [76] FINA [Fédération Internationale de Natation] points) and 30 female (881 [63] FINA points) swimmers was measured in the soleus and gastrocnemius by proton magnetic resonance spectroscopy and expressed as a carnosine aggregate Z score (CAZ score) to estimate muscle typology. A higher CAZ score is associated with a higher estimated proportion of type II fibers. Swimmers were categorized by their best stroke, distance category (sprinters, 50–100 m; middle distance, 200–400 m; or long distance, 800 m–open water), and performance level (world-class, world top 10, or elite and world top 100 swimmers outside of the world top 10). Results: There was no significant difference in the CAZ score of sprint- (−0.08 [0.55]), middle- (−0.17 [0.70]), or long-distance swimmers (−0.30 [0.75], P =.693). World-class sprint swimmers (all strokes included) had a significantly higher CAZ score (0.37 [0.70]) when compared to elite sprint swimmers (−0.25 [0.61], P =.024, d = 0.94). Breaststroke swimmers (0.69 [0.73]) had a significantly higher CAZ score compared to freestyle (−0.24 [0.54], P <.001, d = 1.46), backstroke (−0.16 [0.47], P =.006, d = 1.42), and butterfly swimmers (−0.39 [0.53], P <.001, d = 1.70). Furthermore, within the cohort of breaststroke swimmers, there was a significant positive correlation between FINA points and CAZ score (r =.728, P =.011); however, this association was not evident in other strokes. Conclusion: While there was no clear association between muscle typology and event distance specialization, world-class sprint swimmers possess a greater estimated proportion of type II fibers compared to elite sprint swimmers, as well as breaststroke swimmers compared to freestyle, backstroke, and butterfly swimmers.

Purpose: The ability of elite breaststroke swimmers to maximize average velocity maintained throughout a race is reportedly mediated by a number of range-of-motion, dryland strength–power, and anthropometric characteristics. The present study aimed to develop a physical profile and evaluate the relationship between dryland strength–power and stroke kinematic variables in elite breaststroke swimmers. Methods: A series of range-of-motion, dryland strength–power, and anthropometric measures were assessed in 11 elite-level breaststroke specialists and used to establish group-based averages and expected variance within an elite breaststroke population. Results: Analysis of the relationships between dryland strength–power parameters and breaststroke kinematics revealed strong associations (r >.7, minimum 95% confidence range of g > 0.80 or < −0.80) most frequently at 100-m and maximal paces. From further analysis of these associations, a series of second-order models of best fit were calculated to describe the relationship between dryland strength–power parameters and propulsive velocity. Five models strongly described the relationship between countermovement jump height, mean pull-up velocity, and average propulsive velocity. Conclusions: These models can be used to assess propulsion effectiveness and act as a catalyst for technique evaluation. It is also recommended that strength and conditioning coaches consider the inclusion of explosive movements, such as countermovement jumps and maximal velocity pull-ups, in dryland training programs designed for sprint breaststroke swimmers.

Purpose: Sport-science research consistently contains repeated measures and imbalanced data sets. This study calls for further adoption of mixed models when analyzing longitudinal sport-science data sets. Mixed models were used to understand whether the level of competition affected the intensity of women's rugby league match play. Methods: A total of 472 observations were used to compare the mean speed of female rugby league athletes recorded during club-, state-, and international-level competition. As athletes featured in all 3 levels of competition and there were multiple matches within each competition (ie, repeated measures), the authors demonstrated that mixed models are the appropriate statistical approach for these data. Results: The authors determined that if a repeated-measures analysis of variance (ANOVA) were used for the statistical analysis in the present study, at least 48.7% of the data would have been omitted to meet ANOVA assumptions. Using a mixed model, the authors determined that mean speed recorded during Trans-Tasman Test matches was 73.4 m·min−1, while the mean speeds for National Rugby League Women and State of Origin matches were 77.6 and 81.6 m·min−1, respectively. Random effects of team, athlete, and match all accounted for variations in mean speed, which otherwise could have concealed the main effects of position and level of competition had less flexible ANOVAs been used. Conclusion: These data clearly demonstrate the appropriateness of applying mixed models to typical data sets acquired in the professional sport setting. Mixed models should be more readily used within sport science, especially in observational, longitudinal data sets such as movement pattern analyses. [ABSTRACT FROM AUTHOR]

In this paper, the authors explore how athletes from the Global South interact with the material environment of an international training camp program in the lead up to a major event. Set within the context of Pasifika nations with colonial and missionary legacies, they examine the material, affective, sensory, and rhythmic forces at work to produce enabling or constraining capacities for emplaced physical capital in athletes. Driven by a desire to improve their performance, athletes resisted, appropriated, and adopted various high-performance practices to develop their emplaced physical capital capacities.

Purpose: To determine the influence of muscle fiber typology (MFT) on the pacing strategy of elite swimmers competing in the 200-m freestyle event. Method: The top 3 career-best performances from 25 elite 200-m freestyle swimmers were analyzed—12 women (1:58.0 [0:01.3] min:s) and 13 men (1:48.4 [0:02.5]). Muscle carnosine concentration was quantified by proton magnetic resonance spectroscopy in the gastrocnemius and soleus muscles and expressed as a carnosine aggregate z score (CAZ score) relative to an age- and gender-matched nonathlete control group to estimate MFT. Linear regression models were employed to examine the influence of MFT on the percentage of overall race time spent in each 50-m lap. Results: Swimmers with a higher CAZ score spent a greater percentage of race time in lap 3 compared with swimmers with a lower CAZ score (0.1%, 0.0% to 0.2%; mean, 90% confidence interval, P =.02). For every 1% increase in the percentage of race time spent in lap 1, the percentage of race time spent in lap 3 decreased by 0.4% for swimmers with a higher CAZ score (0.2% to −0.5%, P =.00, r = −.51), but not for swimmers with a lower CAZ score (−0.1%, −0.3% to 0.1%, P =.28, r = −.18). The percentage of race time spent in lap 4 decreased by 0.8% for higher-CAZ-score swimmers (−0.5% to −1.0%, P =.00, r = −.66) and by 0.9% for lower-CAZ-score swimmers (−0.6% to −1.3%, P =.00, r = −.65) when lap 1 percentage increased by 1%. Conclusion: MFT may influence the pacing strategy of swimmers in the 200-m freestyle event, which provides an avenue for maximizing individualized pacing strategies of elite swimmers.

We provide a novel analysis of the locomotor movements of athletes in the National Rugby League Women's (NRLW) competition by presenting the data of opposing teams expressed as a relative (%) difference and explore the association with match outcome. 117 rugby league athletes from the four NRLW clubs participated in this study. Mean speed (m·min−1), mean high-speed running (>12 km·h−1; m·min−1), and mean acceleration (m·s−2) were measured in 12 matches (370 individual match files) using the Global Navigation Satellite System (GNSS). Individual GNSS-derived data from each match-half were summed across each team and the association with total points and the points differential in each match-half was determined using linear mixed models. Greater high-speed running and lower mean acceleration were associated with more points being scored. A greater relative difference in mean high-speed running between competing teams was associated with a higher points differential. That is, if a team completed 10% more high-speed running than their opposition, they were likely to score an average of 3.2 points more during a given match-half. This unique analysis of GNSS-derived data may assist coaches and performance support staff to interpret the locomotor movements of female rugby league players with the appropriate considerations for the opposition team.

Purpose: To determine the association between estimated muscle fiber typology and the start and turn phases of elite swimmers during competition. Methods: International and national competition racing performance was analyzed from 21 female (FINA points = 894 ± 39: 104.5 ± 1.8% world record ratio [WRR]) and 25 male (FINA points = 885 ± 54: 104.8 ± 2.1% WRR) elite swimmers. The start, turn, and turn out times were determined from each of the swimmers' career best performance times (FINA points = 889 ± 48: 104.7 ± 2.0% WRR). Muscle carnosine concentration was quantified by proton magnetic resonance spectroscopy in the gastrocnemius and soleus and was expressed as a carnosine aggregate z score relative to an age- and gender-matched nonathlete control group to estimate muscle fiber typology. Linear mixed models were employed to determine the association between muscle fiber typology and the start and turn times. Results: While there was no significant influence of carnosine aggregate z score on the start and turn times when all strokes and distance events were entered into the model, the swimmers with a higher carnosine aggregate z score (ie, faster muscle typology) had a significantly faster start time in 100-m events compared with the swimmers with a lower carnosine aggregate z score (P =.02, F = 5.825). The start and turn times were significantly faster in the male compared with the female swimmers in the 100-m events compared with other distances, and between the 4 different swimming strokes (P <.001). Conclusion: This study suggests that start times in sprint events are partly determined (and limited) by muscle fiber typology, which is highly relevant when ∼12% of the overall performance time is determined from the start time.

Purpose: To determine whether there is an association between external match load and contextual factors on subjective wellness in the days before and after Australian Rules football match play. Methods: A total of 34 elite male Australian football players completed a subjective wellness questionnaire in the days leading into the match (-3, -2, and -1 d), the day of (match day), and the days after each match (+3, +2, and +1 d). Players subjectively rated each item (mood, energy, stress, leg heaviness, muscle soreness, sleep quality, hours slept, and total wellness [a sum of the total response score]) on a visual analog scale ranging from 1 to 10, with 1 representing the negative end of the continuum. External load during competitive matches was quantified using accelerometer-derived PlayerLoad, and running activity was quantified using global positioning system technology across 2 competitive seasons. The relationships between perceptions of wellness (within-individual z score), external match load, and contextual factors (match result, match location, and between-matches recovery duration) were analyzed using linear mixed models. Results: Mixed-effect linear models revealed trivial effects of match-day wellness z score on subsequent external match load metrics. Match result (win) and PlayerLoad in the anteroposterior vector (au-min-1) were associated with an increased (estimate ± SE: 0.30 ± 0.13 z score) and reduced subjective wellness (-0.15 ± 0.06 z score), respectively. Conclusion: The results of this study suggest that prematch perceived wellness does not relate to external match load in elite Australian football players. The between-matches microcycle length appears to be sufficient to restore perceived wellness to values that do not affect the subsequent external match loads. [ABSTRACT FROM AUTHOR]

Purpose: To compare the training-intensity distribution (TID) across an 8-week training period in a group of highly trained middle-distance runners employing 3 different methods of training-intensity quantification. Methods: A total of 14 highly trained middle-distance runners performed an incremental treadmill test to exhaustion to determine the heart rate (HR) and running speed corresponding to the ventilatory thresholds (gas-exchange threshold and respiratory-compensation threshold), as well as fixed rating of perceived exertion (RPE) values, which were used to demarcate 3 training-intensity zones. During the following 8 weeks, the TID (total and percentage of time spent in each training zone) of all running training sessions (N = 695) was quantified using continuous running speed, HR monitoring, and RPE. Results: Compared with the running-speed-derived TID (zone 1, 79.9% [7.3%]; zone 2, 5.3% [4.9%]; and zone 3, 14.7% [7.3%]), HR-demarcated TID (zone 1, 79.6% [7.2%]; zone 2, 17.0% [6.3%]; and zone 3, 3.4% [2.0%]) resulted in a substantially higher training time in zone 2 (effect size ± 95% confidence interval: −1.64 ± 0.53; P <.001) and lower training time in zone 3 (−1.59 ± 0.51; P <.001). RPE-derived TID (zone 1, 39.6% [8.4%]; zone 2, 31.9% [8.7%]; and zone 3, 28.5% [11.6%]) reduced time in zone 1 compared with both HR (−5.64 ± 1.40; P <.001) and running speed (−5.69 ± 1.9; P <.001), whereas time in RPE training zones 2 and 3 was substantially higher than both HR- and running-speed-derived zones. Conclusion: The results show that the method of training-intensity quantification substantially affects computation of TID. [ABSTRACT FROM AUTHOR]

The mental health of elite athletes is reportedly similar to that of the general community, but there could be important differences across geographic regions and cultures. This study investigated the mental health and levels of psychological distress of elite athletes from developing nations in the Oceania region via a cross-sectional survey. The survey assessed the mental health status, psychological distress, and help-seeking behaviours of athletes from 12 nations of the Oceania region who participated in the Gather, Adjust, Prepare, Sustain (GAPS) program. A high proportion of athletes (84%) met cut-off criteria for at least one of the investigated mental health symptoms. Athletes reported being most likely to seek help from their mother, father, or coach. Furthermore, athletes who reported high psychological distress did not differ in anticipated help-seeking behaviour from athletes who reported low psychological distress. The findings suggest that mental health symptoms are prevalent among elite athletes from developing nations in the Oceania region. Psychological distress did not predict willingness to seek help, suggesting that education and support frameworks are needed to assist this vulnerable group. Piloting support programs in collaborative aid with nearby developed nations may be warranted and interventions may consider targeted mental health literacy resources and education. What is already known about this topic: The demands athletes face increases their susceptibility to elevated mental health symptoms. Athletes may not seek help for mental health symptoms due to psychological (i.e., stigma) and physical (i.e., geographical) barriers. There is limited research on mental health symptoms and outcomes for athletes, especially among those from developing nations. What this topic adds: A high proportion of athletes (84%) exceeded cut-off scores for elevated psychological distress or a mental health symptom related to depression, anxiety, or eating. Athletes were more likely to seek help from their parents or coach than a mental health professional. Higher psychological distress did not predict help-seeking behaviour thus identifying a need for support programs and collaborative aid. [ABSTRACT FROM AUTHOR]
