Purpose: This study investigated the effect of summer camp session context on Russian girls' physical activity (PA). Method: Girls (n = 32, M[subscript age] = 10.7 years, SD = 0.6 years) from a resident summer camp taking place in the Vologda Region of Russia were exposed to 1 session context/day (i.e., free play, organized with no choice, organized with choice) on Wednesday, Thursday, and Friday for 3 weeks, with the context order counterbalanced across the 3 weeks. The organized session sport/game changed weekly. The primary outcome was accelerometer-assessed PA. Repeated-measures mixed models were used to analyze all outcome data. Results: Findings showed that girls spent a greater percentage of session time (%time) in moderate-to-vigorous PA (p < 0.001; effect sizes between free play and organized with no choice and organized with choice, respectively = 0.60, 0.42) and moderate PA (p < 0.001; effect size = 0.57, 0.39) and a lower %time in light PA (p < 0.001; effect size = 0.55, 0.52) in organized PA contexts compared with free play. Conclusions: This study provides novel findings in a Russian setting, suggesting that a well-planned, organized camp session can elicit higher PA levels in girls, relative to a free-play session.

Purpose: We studied whether physical activity (PA) counseling for parents influenced the level of parental support of children's PA and leisure-time PA in children of different levels of initial parental support. We hypothesized that the initial level of parental support would moderate the intervention efficacy. Method: Children (n = 44, M[subscript age] = 6.09 ± 1.17 years) and their parents (n = 61) randomly assigned to an intervention group received counseling for 6 months. Children in the control group (n = 47, M[subscript age] = 6.12 ± 1.11 years) and their parents (n = 63) did not receive any counseling. Parental support was assessed using the Family Physical Activity Environment Questionnaire, and children's leisure-time PA was recorded using triaxial accelerometers at baseline, at 6 months, and at 12 months. The efficacy of the intervention was tested by linear mixed-effects modeling adjusted for confounding variables (Model 1) and additionally for children's participation in organized PA or sports (Model 2). Results: Parents within the lowest initial parental support intervention tertile significantly increased their support, and their children's mean level of leisure-time PA significantly improved compared with the corresponding controls during the counseling period. On the other hand, intervention was found to have an unfavorable influence especially in the PA of children of initially highly supportive parents. Conclusion: Targeting PA counseling for parents with low support of their children's PA could contribute to better family-based PA counseling efficacy.

Background: The World Health Organization recognizes that physical activity (PA) during childhood is crucial for healthy development, aligning well with the achievement of several United Nations (UN) Sustainable Development Goals (SDGs). This study aimed to explore the associations between 10 key indicators of PA for children and adolescents assessed in the Global Matrix 4.0 project, and the UN SDGs. Methods: Data from 57 countries/jurisdictions of the Global Matrix 4.0 project were used. The UN SDG indicators were sourced from the SDG Transformation Center, which publishes each country's performance on each of the 17 SDGs. Given the robust evidence supporting plausible links between PA and SDGs 3 (good health and well-being), 9 (industry, innovation, and infrastructure), 11 (sustainable cities and communities), 13 (climate action), and 16 (peace, justice, and strong institutions), these SDGs were investigated. Results: Countries/jurisdictions with good and moderate performance in achieving SDG 3, SDG 9, SDG 11, and SDG 16 had higher grades than countries/jurisdictions with fair performance in achieving these SDGs for the following indicators: Organized Sports and PA, Community and Environment, and Government Investments and Strategies. However, countries/jurisdictions with good performance in achieving SDG 13 had lower grades than countries/jurisdictions with fair performance in achieving SDG 13 for the following indicators: Organized Sports and PA, Community and Environment, and Government Investments and Strategies. Conclusions:Organized Sports and PA, Community and Environment, and Government Investments and Strategies were the indicators that demonstrated differences between countries/jurisdictions with good and poor performance in achieving the SDGs.

Background: Physical activity is crucial for maintaining health and preventing chronic diseases. However, climate conditions can impact physical activity patterns, and conversely, physical activity can impact climate change. This umbrella review aims to summarize the existing evidence regarding the relationships between physical activity and climate change, as revealed in previous reviews. Methods: Systematic reviews and meta-analyses were analyzed. Searches were conducted across GreenFILE, PubMed, and Web of Science databases for peer-reviewed articles published in English. A 2-stage independent screening process was conducted, and methodological quality was assessed using the JBI framework. Standardized data extraction methods were then applied. Results: Out of 1292 articles retrieved, 7 met all eligibility criteria and were included in the review. Three articles examined physical activity as a primary exposure, 3 focused on the impacts of climate change, and one considered both physical activity and climate change as primary exposures. Conclusions: Findings reveal an interplay between climate change and physical activity. While rising temperatures may prompt outdoor activities up to a certain temperature threshold, air pollution and extreme heat can have harmful effects. Active transportation and improved logistics around large-scale sporting events can mitigate climate change by reducing greenhouse gas emissions, but transportation systems linked to sports venues may increase emissions. Research on the reciprocal relationship between climate change and physical activity domains, and integrating the community into climate discussions, is crucial for equity, especially for marginalized communities. Incorporating climate adaptation and mitigation strategies in physical activity infrastructure to minimize environmental impacts is critical. [ABSTRACT FROM AUTHOR]

Physical activity program interventions often lack sensitivity to the needs of older immigrant adults. The objective of this systematic realist review is to explain how, why, for whom, and under which circumstances community group-based physical activity programs work for immigrant older adults. The initial program theory was developed using prior research, team expertise, social cognitive theory, and knowledge user consultations. The program theory was tested and refined via a systematic review of the literature. Database searches were conducted in MEDLINE, EMBASE, CINAHL, Scopus, Cochrane Library, Sports Medicine and Education Index, and SPORTDiscus. A total of 22 sources of evidence met inclusion criteria and included intervention studies, systematic reviews, and a discussion paper. Intervention studies were appraised using the Mixed Methods Appraisal Tool. The final program theory constituted eight context–mechanism–outcome configurations that highlight the importance of facilitator characteristics, access to safe spaces, group dynamics, and social support. A limitation was the small number and variable quality of included evidence. Physical activity programs that target immigrant older adults must strengthen physical and psychological safety and maximize opportunities for role modeling and socialization. This research was supported by the Alberta Health Services Seniors Health Strategic Clinical Network and is registered in PROSPERO (ID#258179). [ABSTRACT FROM AUTHOR]

The author reflects on the discomfort of engaging with relational practices in academia, particularly within sport history, and the need for critical self-reflection on positionality. Topics include Japanese gift-giving and the cultural significance of "wrapping," the challenge of unwrapping discomfort in academic practices, and the role of positionality in shaping research and teaching in sport history.

Strength is a central element of sport and therefore an equally central topic in sports science. In sports science, strength is dealt with primarily in biomechanics. Biomechanics reduces strength – legitimately – to a scientific subject. As a result, it loses sight of strength as a lifeworld phenomenon. The discipline that allows us to grasp strength as an everyday experience is phenomenology. This essay undertakes a phenomenological analysis of strength to uncover the diversity of strength phenomena in the lifeworld of sport. The theoretical and methodological basis for this is Hermann Schmitz's 'new phenomenology' (Neue Phänomenologie). With the help of new phenomenology, I first develop a real definition of strength ('strength is an intrusive effect through one-sided incorporation'). Second, I work out the general structures of the phenomenon of 'strength', that is, a system comprising ten categories ('pulling, pushing, centripetal, centrifugal, lifting, lowering, strong, weak, heavy, light'). Third, I use this system of categories for a phenomenology of sport-immanent strength phenomena. The paper thus makes a contribution to a pure phenomenology of sport. [ABSTRACT FROM AUTHOR]

Sport categorization is often justified by benefits such as increased fairness or inclusion. Taking inspiration from John Rawls, Sigmund Loland's fair equality of opportunity principle in sport (FEOPs) is a tool for determining whether the existence of an inequality ethically justifies the institution of a new category in any given sport. It is an elegant ethical normative framework, but since FEOPs does not account explicitly for athlete safety (i.e. athlete physical and mental wellbeing), we are left in an ethically dubious situation where the risk of harm associated with a categorization regime might in fact prove to be greater than the risk of harm present within the sport before its introduction. To address this critical gap, I propose the 'scales of ignorance' ethical normative framework to weigh the relative risk of harm within a sport, crucially inserting athlete safety into the discourse surrounding ethical justification for categorization in sport. The current paper is the first explicit formulation of assessment and ethical justification of risk of harm in the familiar logic of FEOPs. The scales of ignorance framework can also be used independently of Loland's approach. Two new concepts are also proposed: 'insidious risk of harm' and 'pernicious risk of harm'.

In this paper, we explore the lived experiences of mother-coaches who, while coaching, navigate policy and programs aimed at promoting gender equity. Specifically, this study took place within the context of an amateur national, 10-day multisport games event in Canada. Using critical feminist narrative inquiry, 14 mother-coaches (apprentice, assistant, or head coach), representing eight different provinces, and 10 different sports, participated in this study. Three themes were constructed that call attention to the Canadian sport system broadly, as well as the 10-day multisport games event specifically: (a) performative policies and gendered assumptions, (b) programs that are band-aids for a "shitty culture," and (c) a pathway to nowhere for mother-coaches. The findings complicate the hegemonic work–family conflict narrative, suggesting that mother-coaches' advancement, opportunities, and quality experiences are impacted by the current heteropatriarchal culture and structure of sport that these programs and policy are rooted in.

Background: The benefits of oral caffeine intake to enhance several aspects of physical performance, such as aerobic endurance, strength, power, and muscle endurance performance, are well supported. However, how the physical performance benefits of caffeine supplementation are translated into better specific actions in intermittent sports during real or simulated competition has been the topic of fewer investigations, and their results need to be appropriately reviewed and meta-analyzed. Objective: The aim of the study was to investigate the effects of acute caffeine intake on specific actions in intermittent sports involving decision making and high-intensity efforts (eg, team, racket, and combat sports) during real or simulated competitions. Methods: All studies included had blinded and crossover experimental designs, and we conducted a risk-of-bias analysis. In total, we included 24 studies. A meta-analysis was performed using the random-effects model to calculate the standardized mean difference (SMD) estimated by Hedges g and 95% CIs. Results: Caffeine ingestion increased high-intensity sport-specific actions during competition, such as the number of sprints (SMD: 0.48; 95% CI, 0.23–0.74), body impacts (SMD: 0.28; 95% CI, 0.08–0.49), accelerations (SMD: 0.35; 95% CI, 0.06–0.63), decelerations (SMD: 0.63; 95% CI, 0.12–1.14), and high-intensity offensive efforts (SMD: 0.36; 95% CI, 0.11–0.61). Additionally, caffeine ingestion induced a higher positive or success rate of actions during real or simulated competition (SMD: 0.44; 95% CI, 0.19–0.69). Conclusion: The current meta-analysis provides evidence of caffeine supplementation in increasing high-intensity efforts and the success rate of sport-specific actions during real or simulated competition.

Purpose: To gather information on practices and perceptions of high-performance experts regarding their athletes' muscle fiber-type composition (MFTC) and its estimation. Methods: A questionnaire on the noninvasive versus invasive estimation of MFTC was completed by 446 experts including coaches and sport-science/sports-medicine staff. Moreover, the perceived importance of MFTC for training and performance optimization was assessed. Differences between sport types (individual and team sports) were analyzed using chi-square tests. Results: Forty percent of the experts implemented MFTC assessment in pursuit of performance optimization, while 50% did not know their athletes' MFTC but expressed a desire to implement it if they would be able to assess MFTC. Ten percent did not perceive value in MFTC assessment. Only 18% of experts believed that their athletes would undergo a muscle biopsy, leading to the adoption of alternative noninvasive techniques. Experts primarily relied on their experience to estimate MFTC (65%), with experts working in individual sports using their experience more frequently than those working in team sports (68% vs 51%; P =.009). Jump tests emerged as the second-most commonly employed method for estimating MFTC (56%). When only considering experts who are currently using MFTC, 87% use MFTC to individualize training volume and 84% to individualize training intensity. Conclusions: Experts value MFTC assessment primarily to individualize training but mainly rely on noninvasive methods to estimate MFTC. Some of these methods lack scientific validity, suggesting a continuing need for education and further research in this area. [ABSTRACT FROM AUTHOR]

I offer a modified definition of sport. Some have claimed that it is impossible to define sport. I believe it is possible to give a definition, understood as articulating intuitive views about what correct usage of the word is. Through an examination of competitive cooking and Esports, I argue that a common definition of sport as a game of physical skill needs to be modified to account for why these should not be considered sports. Although cooking involves physical skill, what is judged in a cooking competition is a product, not physical skill itself. Esports do involve physical skill, but I claim that the common use of sport requires gross motor activity that uses most of the body, whereas the popular Esports only require hand and arm movement. My modified definition is that sports are games of gross motor skill which do not produce a product distinct from the skill itself. I conclude with consideration of some borderline cases.

Background: We aimed to evaluate the effectiveness of the combination of protein supplementation and resistance training (RT), compared with RT alone or combined with a placebo, in improving gait speed. Methods: We searched PubMed, Web of Science, Cochrane Library, and SPORTDiscus databases, and 18 randomized controlled trials with 1,147 older participants were included for meta-analysis. Data were pooled as the effect sizes (Hedges' g) with 95% confidence interval (CI) of the gait speed (in meters per second). The random-effect meta-analysis, subgroup analyses, meta-regression, and sensitivity analysis were conducted. Results: The combination of protein supplementation and RT significantly improved gait speed (Hedges' g: 0.52 m/s, 95% confidence interval [0.17, 0.86], p =.005; I2 = 86.5%) compared with the RT alone. The subgroup analyses revealed that the significant improvement in gait speed postprotein intervention plus RT was observed only in participants who consumed protein after RT (Hedges' g: 0.90 m/s, 95% confidence interval [0.46, 1.33], p =.001; I2 = 79.6%). The pooled result did not significantly change after excluding any single study at one time or excluding smaller studies with large effect sizes. Conclusions: Protein supplementation combined with RT could significantly improve the gait speed of older adults compared with RT alone. This positive effect is more pronounced in people who consume protein after RT. [ABSTRACT FROM AUTHOR]

Objective: To analyze the influence of congested and noncongested fixture periods during 2 seasons in a professional male football team on soft-tissue injury incidence and external load. Methods: Thirty-three professional football players from a Portuguese Liga I team participated in this study. Weekly external load and soft-tissue injury rate and burden of 2 consecutive seasons (2021–22 and 2022–23) were analyzed. Results: Total soft-tissue injury rate and burden for the 2 seasons were 3.9 and 3.2 injuries per 1000 hours and 71.8 and 60.5 days per 1000 hours for congested and noncongested periods, respectively. No significant differences were observed between congested and noncongested periods. Total high-speed running, sprint distance, distance above 80% and 90% of maximal velocity, and meters accelerating and decelerating above 2 m/s2 were significantly higher for noncongested weeks. Match accelerations and decelerations above 3 m/s2 were higher during congested periods and training during noncongested periods. No differences between the 2 periods were observed for the total number of accelerations and decelerations above 3 m/s2. Overall, physical outputs per week were higher for training during noncongested weeks, whereas matches during congested periods registered higher external load. Conclusions: No effect of a congested schedule was observed on soft-tissue injury rates and injury burden. Higher match exposure during congested periods increased external load performed per week, and during noncongested periods, training load was superior to congested weeks. [ABSTRACT FROM AUTHOR]

Purpose: Travel fatigue impacts cognitive and physiologic systems, but its association with elite soccer match performance is unclear. In this retrospective observational study, we aimed to explore the association between travel and match outcomes in elite North American soccer. Methods: Travel data and match outcomes (team points or goals scored and conceded) and physical performance outcomes from 26 elite professional soccer teams and their players were analyzed (148 matches [team-based data] and 1252 player matches from 297 players; age 22.7 [4.5] y). Player- and match-level correlations between performance measures and both acute and cumulated travel metrics were analyzed. Results: Cumulative travel metrics were positively associated with team (travel distance [r =.20; 95% CI,.03–.25], travel time [r =.20;.06–.37], and time away [r =.20;.06–.37]) and individual player (travel distance, [r =.14;.08–.19], travel time [r =.17–.23], and time away [r =.13;.07–.18]) high-intensity running. Cumulative time away was negatively associated with team points (r = −.14; −.28 to −.001) and positively associated with goals conceded (r =.14;.01–.27); no clear association between acute travel metrics and match outcomes or physical performance was observed. Conclusions: As travel cumulated, away teams and their players ran more but for less reward (team points), although the magnitude of these associations was small. These data are exploratory and do not imply a causal relationship; however, further research should consider cumulation of travel. [ABSTRACT FROM AUTHOR]

Challenge and threat (C/T) states have been shown to predict sport performance under pressure. Nevertheless, only one study has examined whether preseason C/T states are associated with season-long performance, yielding promising findings. Despite promising findings, this work is not without limitations that warrant addressing. We aimed to address these limitations and contribute to the scarce literature which tests the effect of anticipatory C/T states on longer term performance. Thirty-eight amateur cricketers prepared and delivered two counterbalanced speeches: a control speech and a speech about an important cricket batting situation approximately 16 weeks prior to the start of their competitive season. Regression analysis showed that cardiovascular reactivity in anticipation of delivering a speech about an important cricket batting scenario the next season did not predict season-long batting performance. The findings have potential to challenge the role C/T states play in predicting longer term performance in the sport domain. [ABSTRACT FROM AUTHOR]

Context: We designed this study to investigate the effects of 2 myofascial release techniques, Instrument-Assisted Soft Tissue Mobilization (IASTM) and Foam Roller (FR), on pain, joint range of motion, and muscle strength in athletes suffering from iliotibial band (ITB) tightness. Design: A total of 39 male soccer players were enrolled in this randomized controlled trial, aged between 18 and 23 years who were divided into 3 groups: Only Exercise, IASTM, and FR. Methods: All participants performed daily strengthening and stretching exercises, while 1 group added IASTM, and the other added FR to the exercise program. We evaluated ITB tightness with the Ober test and an inclinometer, pressure pain threshold, using an algometer, and we evaluated muscle strength with the Cybex Norm Isokinetic device. Results: We found that all 3 groups exhibited an increase in the Ober inclination angle after the interventions (P =.001), but the increase was greater for participants in the IASTM and FR groups, compared with exercise alone. Additionally, both the IASTM and FR groups displayed an increased pressure pain threshold (P =.001), whereas there was no change in the control group. Moreover, while all 3 groups experienced an increase in hip muscle strength (P =.001), the IASTM and FR groups exhibited a greater increase compared with exercise alone (P =.001). Conclusions: Based on these findings, exercise improves pain, range of motion, and muscle strength in athletes with ITB tightness, and IASTM, and FR techniques enhanced exercise effects but did not differ from one another. While our study demonstrated that both IASTM and FR techniques significantly enhance the benefits of exercise for athletes with ITB tightness, further research could delve into the long-term effects of these interventions.

Context: The best current evidence supports the effectiveness of neuromuscular training in reducing the risk of injury; however, the rate of anterior cruciate ligament (ACL) injuries is still high. Neurocognitive training (NT) has successfully improved biomechanical risk factors, but they have been considered in only a few studies. Objective: To review the literature to determine the effect of NT on biomechanical risk factors related to ACL injury in athletes. Evidence Acquisition: We searched PubMed, Google Scholar, Scopus, Science Direct, and the Physiotherapy Evidence Database from inception to August 2011. We included randomized controlled trials that used motor learning approaches and injury prevention programs to investigate kinematic and kinetic risk factors related to ACL injury. The quality of each clinical trial study was evaluated by the Physiotherapy Evidence Database scale. The eligibility criteria were checked based on the PICOS (population, intervention, comparison, outcome, and study type) framework. Evidence Synthesis: A total of 9 studies were included in the final analysis. Motor learning approaches include internal and external focus of attention, dual tasks, visual motor training, self-control feedback, differential learning, and linear and nonlinear pedagogy, combined with exercise programs. In most of the studies that used NT, a significant decrease in knee valgus; tibial abduction and external rotation; ground reaction force; and an increase in knee-, trunk-, hip-, and knee-flexion moment was observed. Conclusion: In classical NT, deviation from the ideal movement pattern especially emphasizing variability and self-discovery processes is functional in injury prevention and may mitigate biomechanical risk factors of ACL injuries in athletes. Practitioners are advised to use sport-specific cognitive tasks in combination with neuromuscular training to simulate loads of the competitive environment. This may improve ACL injury risk reduction and rehabilitation programs. [ABSTRACT FROM AUTHOR]

Sport retirement is a major life transition that student-athletes must navigate successfully to achieve adaptation to post-sport life. Numerous factors dictate the likelihood of successful adaptation, one of which is athletic identity. Based on thorough review of the occupational retirement literature, it has been determined that adaptation can be measured by life satisfaction. Therefore, the purpose of this study was to determine how athletic identity impacts present-day life satisfaction and if meaning in life mediates that effect. Meaning in life can be separated into two categories, the presence of and search for meaning in life. Through a quantitative survey of 104 former Division I student-athletes, we discovered significant relationships between the search for and presence of meaning in life and life satisfaction. No relationship was found between athletic identity and life satisfaction. Thus, retrospective athletic identity does not predict present-day life satisfaction unless the mediating effect of the search for meaning in life is present. Additionally, group differences were measured between sexes, type of sport played (e.g., draft eligible or non-draft eligible), and predictability of retirement. There were significant differences on the Athletic Identity Measurement Scale between males (M = 36.1, SD = 7.9) and females (M = 32.1, SD = 7.8), t(100) = 2.55, p = .01. [ABSTRACT FROM AUTHOR]

Context: The Hip Stability Isometric Test (HipSIT) is commonly employed in clinical settings for evaluating the hip posterolateral muscle strength. In this study, we introduced the "Field Hip Stability Isometric Test" (F-HipSIT) and assessed the intrarater and interrater reliability of this strength assessment specifically designed for sports settings. Design: Reliability study. Methods: Two independent raters (A and B) went to athletes' training facilities to conduct 2 sessions of F-HipSIT spaced at least 1 week apart. The average peak force value from 3 valid attempts of each leg was recorded and normalized by the participant's body mass for statistical analysis. Results: Thirty male and 30 female amateur athletes took part in this study. Rater A obtained similar values in the first (0.39 [0.05] and 0.44 [0.07] kg·f/kg) and second (0.39 [0.06] and 0.45 [0.07] kg·f/kg) testing days for men and women, respectively. Rater B also found similar values in the first (0.35 [0.06] and 0.42 [0.08] kg·f/kg) and second (0.36 [0.06] and 0.45 [0.08] kg·f/kg) testing days for men and women, respectively. Excellent intrarater intraclass correlation coefficient (ICC) values were found for men (ICC =.922) and women (ICC =.930), with coefficient of variation of 6% to 8% and minimal detectable change of 0.06 to 0.10 kg·f/kg. The F-HipSIT presented good interrater reliability for men (ICC =.857) and women (ICC =.868), with coefficient of variation of 5% and minimal detectable change of 0.05 to 0.06 kg·f/kg. Conclusion: The F-HipSIT intrarater and interrater reliability among male and female recreational athletes supports this field test as a quick and convenient screening tool to monitor hip posterolateral muscle strength in sports settings.

Clinical Scenario: Individuals with chronic ankle instability (CAI) typically complete balance training protocols to improve postural control and reduce recurrent injury risk. However, the presence of CAI persists after traditional balance training protocols suggesting that such programs may be missing elements that could be beneficial to patients. Visual occlusion modalities, such as stroboscopic goggles, may be able to augment balance training exercises to further enhance postural control gains in those with CAI. However, a cumulative review of the existing evidence has yet to be conducted. Focused Clinical Question: Does wearing stroboscopic goggles during balance training result in greater improvements to postural control than balance training alone in those with CAI? Summary of Key Findings: All 3 studies indicated that the stroboscopic goggles group had statistically significant improvements in either a measure of static or dynamic postural control relative to the standard balance training group. However, significant improvements were not consistent across all postural control outcomes assessed in the included studies. Clinical Bottom Line: Postural control may improve more in those with CAI when stroboscopic goggles were worn while completing balance training exercises relative to completing balance training exercises alone. Strength of Recommendation: Overall, consistent moderate- to high-quality evidence was present in the 3 studies, suggesting grade C evidence for the use of stroboscopic goggles during balance training in those with CAI.

Context and Objectives: Respiratory muscle training (RMT) is considered an effective tool to improve cardiorespiratory limitations in athletes. The goals of this systematic review were to explore the role of RMT and its implementation within sport rehabilitation programs in para-athletes. Evidence Acquisition: Several databases were searched until January 2024. Eligible studies were independently reviewed by 2 reviewers. Quality assessment was made using the PEDro scale and version 2 of the Cochrane Risk-of-Bias Tool for Randomized Trials. Eight studies (a total of 108 participants) were selected for the analysis. Evidence Synthesis: Five studies preferred using resistive loading, while 2 studies used normocapnic hyperpnea, and 1 study used threshold inspiratory muscle training. Respiratory functions (respiratory muscle strength and endurance, spirometry measures) and exercise performance were assessed as the main outcomes. Significant increases in respiratory muscle strength were reported in 5 studies. Two studies observed improvement in respiratory muscle endurance and 3 studies reported increased exercise capacity. Conclusions: This review suggests that although RMT can enhance respiratory muscle strength and endurance, it should not be considered the primary method for boosting the exercise performance of para-athletes. Additional research is necessary to explore the impact of various RMT techniques on different outcomes from the perspective of sport rehabilitation in para-athletes. [ABSTRACT FROM AUTHOR]

Assessment of player's postural control following a lower limb injury is of interest to sports medicine practitioners due to its fundamental role in daily tasks and sporting activities. The aim was to longitudinally monitor professional rugby union players' postural control during each phase of the rehabilitation program (acute, middle, and late) following a lower limb injury. Seven male rugby union players (height 1.80 [0.02] m; mass 100.3 [11.4] kg; age 24 [4] y) sustained a time loss, noncontact lower limb injury. Static postural control was assessed via sway path (in meters), and dynamic postural control was assessed via vertical postural stability index. Group differences (P <.05) were reported across the acute, middle, and late phase. Smaller magnitudes of sway path were observed for eyes-open sway path, and for the middle and late phase smaller magnitudes of vertical postural stability index (P <.05) at the end session compared with first session. Whereas larger magnitudes of vertical postural stability index were found between baseline and the last session (P <.05). Large interindividual and intraindividual variation was apparent across the 3 phases of rehabilitation. Postural control improvements were identified during rehabilitation. However, postural control did not return to baseline, with altered kinetics throughout each rehabilitation phase. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this review was to evaluate the effects of physical activity on children's free recall, cued recall, and recognition episodic memory and to explore potential moderating factors. Methods: The following databases were searched: PubMed, ERIC, APA Psych Info, CINHAL, SPORTDiscus, and Google Scholar. Studies were included if: (1) participants were aged 4–18 years, (2) participants were typically developed, (3) participants were randomized to groups, (4) interventions employed gross movements, (5) sedentary group was used for control, (6) memory tests were quantitative, and (7) employed acute or chronic intervention. Results: 14 studies met inclusion criteria resulting in the analysis of data from 7 free recall, 7 cued recall, and 8 recognition memory tests. Physical activity was found to have a positive influence on tests free (g = 0.56), cued recall (g = 0.67), and no influence on tests of recognition (g = 0.06). While some moderator analyses were significant, the authors do not consider these results to be meaningful in application. Conclusions: The effects of acute and chronic physical activity enhance specific aspects of long-term episodic memory. These findings suggest physical activity interventions developed for children may be expected to benefit some, but not all, types of memory processing. [ABSTRACT FROM AUTHOR]

Purpose: This meta-analysis aimed to (1) provide a comparison of peak changes in indirect markers of exercise-induced muscle damage (EIMD) in youths versus adults and (2) determine if the involved limb moderated this effect. Method: Studies were eligible for inclusion if they (1) provided a human youth versus adult comparison; (2) provided data on muscle strength, soreness, or creatine kinase markers beyond ≥24 hours; and (3) did not provide a recovery treatment. Effect sizes (ES) were presented alongside 95% confidence intervals. Results: EIMD exhibited larger effects on adults than in youths for muscle strength (ES = −2.01; P <.001), muscle soreness (ES = −1.52; P <.001), and creatine kinase (ES = −1.98; P <.001). The random effects meta-regression indicated that the effects of upper- and lower-limb exercise in youths and adults were significant for muscle soreness (coefficient estimate = 1.11; P <.001) but not for muscle strength or creatine kinase (P >.05). As such, the between-group effects for muscle soreness (ES = −2.10 vs −1.03; P <.05) were greater in the upper than lower limbs. Conclusion: The magnitude of EIMD in youths is substantially less than in their adult counterparts, and this effect is greater in upper than lower limbs for muscle soreness. These findings help guide practitioners who may be concerned about the potential impact of EIMD when training youth athletes. [ABSTRACT FROM AUTHOR]

Purpose: To compare the standard Yo-Yo intermittent recovery (IR) test and an agility Yo-Yo IR test with a higher number of change-of-direction movements to cardiorespiratory match performance. Methods: The study included 11 professional male handball players (age 24.5 [4.6] y) of a German second-league team. The performance parameters of the players of the seasons 2016–17 to 2018–19 were analyzed. The Yo-Yo IR test was compared to a Yo-Yo IR test with multiple multidirectional changes of direction in response to visual stimuli, which was conducted on a SpeedCourt (Yo-Yo SC IR). Peak oxygen uptake (VO2peak) and maximum heart rate (HRmax) were measured. Between-methods differences of individual athletes were quantified with Bland–Altman plots. Results: HRmax was not statistically different during the Yo-Yo SC IR test compared to the Yo-Yo IR test (181 [10] vs 188 [8] beats·min−1; P =.16). Agreement between the 2 tests was moderate for HRmax and good for heart rates >180 beats·min−1. Mean average VO2peak was 51.7 (3.9) and 50.9 (2.8) mL·min–1·kg–1 for the Yo-Yo SC IR test and the Yo-Yo IR test (P =.693), respectively. Conclusions: A Yo-Yo test with multidirectional changes of direction in response to visual stimuli yielded good agreement with the frequently used linear running tests and can be used to assess players' VO2peak. The HRmax achieved during this test should be used with caution. [ABSTRACT FROM AUTHOR]

This study evaluated physical activity interventions designed for individuals with visual impairments and sought to guide health intervention scientists aiming to promote physical activity in this demographic. We delved into the specifics of participants' visual impairments, intervention features, accommodation approaches, and replicability prospects. The search spanned four databases, namely PubMed, CINAHL, SportDiscus, and Scopus, providing a wide scope and diversity of potential studies. There were no restrictions on publication years. We reviewed 13 studies, totaling 15 interventions. A consensus on visual-impairment definitions remains elusive, and the intervention dosages displayed variability. Notably, 66.7% (n = 7) integrated behavior-change techniques to amplify physical activity levels. Multiple studies employed audio descriptions as an accommodation method. While most studies provided adequate information for potential replication, detailed study protocols were frequently absent. It is essential for developed interventions to be persistently evaluated and fine-tuned to optimize results. [ABSTRACT FROM AUTHOR]

In this paper, we analyze the subjective inclusion experiences of visually impaired (VI) adult tennis players from an ableism-critical perspective. The primary focus of this research is the inclusive potential of blind tennis from the perspective of VI individuals. Episodic interviews were conducted to capture subjective perspectives. A qualitative text analysis revealed that the interviewees were confronted with multiple ability assumptions by sighted people in their everyday lives. Deficit notions on the performance of VI people included sports, work, and general activities. Participation in blind tennis helped the interviewees build a "competent identity" and acquire various skills useful for their everyday lives as participation in blind tennis was a pathway for competence in sports. Further research is needed to identify exclusion experiences from the perspective of disabled people to recognize the potential of different sports in reducing barriers to participation.

The article focuses on surfing to consider the attractiveness of using the sublime to describe experiences and emotions in nature sports. The sublime is shown to be a red herring in scholarship as it fails to account for many of the valuable experiences available to nature sports enthusiasts. The article draws on the work of Genevieve Lloyd to propose that wonder is a more suitable concept that gets to the heart not only of the terror and awe that nature can inspire, but also to the orientation towards our finitude, difference, and the stimulation of growth and practical knowledge that nature sports also inspire (and that are not accounted for in the sublime).

Since the 1970's there has been a major increase in adventure sports participation but it seems that engagement in such sports comes with a stigma: adventure sports participants are often regarded as reckless 'daredevils'. We approach the questions about people's perception of risk and recklessness in adventure sports by combining empirical research with philosophical analysis. First, we provide empirical evidence that suggests that laypeople tend to assess the danger of adventure sports as greater than more mundane sports and judge adventure sports participants as more reckless than participants in non-adventure sports. We contextualise these findings within existing psychological risk perception paradigms and outline new philosophical explanations of the identified pattern in laypeople's risk perception.

Where sporting games may be said to epitomize our species' unique agential capacity for playful movement, sports played in nature differ from their equivalent played indoors in that they envelop the human agent within the living physical environment from which our agency originates. In this paper, we draw attention to how sporting sites differ according to origin by pursuing a biosemiotic line of reasoning. Here, the story of a meaningful human life begins with the eukaryotic cell, even though the human subject itself arises much later. As such, the story of nature in relation to our agency, here, in sports, changes too. We present key concepts from biosemiotics, including its continuum life-as-semiotic-agency view, Umwelt, metasemiosis, and semiotic scaffolding to advance our argument that naturogenic sporting sites provide continuity to the macro processes that have generated our semiotic ability to play. Meanwhile, secluded anthropogenic environments constitute yet another discontinuity for the modern sportsperson where the moving body steps into an anthroposemiotic loop and its restricted signscapes from centralized agency. We conclude on the primacy of naturogenic sporting sites as they preserve the quality and complexity of animal ludens' constitutive relations and therefrom semiotic freedom, on which current and future gameplaying depends.

Nature sports include pursuits such as paragliding, white-water kayaking, free diving, mountaineering, and surfing. Participants in nature sports interact with geographical features (e.g. mountains, rivers, oceans, snow fields, ice sheets, caves, rock faces) as well as the dynamic forces that produce them (e.g. gravity, waves, thermal currents, flowing water, wind, rain, sun). In this article, I engage a representational approach to analyze how participants in nature sports interact with nature. Anthropocentric representations privilege participants' interests, wants, desires, and ends; they typically refer to claims of conquest/achievement in nature, or praise nature for its therapeutic qualities. In contradistinction, ecocentric representations recognize humankind as one entity in an interdependent world that comprises all living organisms and the geological processes and geomorphological features that sustain them. Ecocentric representations of nature sports highlight networks of participants and landforms that help preserve a balance between people and the environment. Yet, notwithstanding the allure of ecocentric representations, especially in the wake of evidence that human-induced greenhouse gases are predisposing environmental calamities, there is a substantial gap between the ontological concepts and categories of ecocentrism and lived sporting experiences and practices in nature.

This paper deals with the question of whether nature sports are to be counted among the (traditional) sports and Kevin Krein's recent argument, based on sporting excellence, as to why they should. Krein argues that sports as such are ultimately about sporting excellence and because both so-called traditional sports and nature sports fulfil that criterion, nature sports belong in the sport domain. Here, I show that Krein's argument rests on an equivocation between two concepts of sporting excellence. Sporting excellence in traditional sports is connected to sporting success. Here agon (contest or competition) dictates or frames areté (striving for excellence). This is not the case for sporting excellence in nature sports, as these are not competitions. We are dealing with two different concepts of sporting excellence and Krein's argument, based on sporting excellence, must be rejected. It gives no basis for including nature sports in the sport domain. [ABSTRACT FROM AUTHOR]

Ethical questions normally arise in sport because its participants are human moral agents and because its practice community entails the observance of rules and responsibilities that humans generally owe one another in a social practice of voluntary competition. Since nature sports are not defined by this kind of inter-agential activity, it would appear that there are no comparable ethical constraints on their pursuit. This paper considers conflicts of preference versus right between humans, how these are resolved, and whether these rights are relevant in assessment of nature sport activity vis-à-vis nonhuman creatures. Relying on a goods perspective instead of a rights framework, via Korsgaard, I argue against an assumption that human preference is sufficient to override consideration of nonhuman animals' functional goods.

The term 'nature sports' can be understood in different ways, depending on how the words 'sport' and 'nature' are explained. Since 'nature' is usually understood as 'ungroomed', 'nature sports' may be interpreted either as non-competitive practices in ungroomed nature (as discussed by Krein), with examples such as backcountry skiing, climbing or surfing; or as competitive sports in ungroomed nature. This paper argues that those ultra sports that take place in ungroomed nature, such as ultra swimming and ultra running, are better candidates for being called 'nature sports' than those non-competitive ones suggested by Krein; and that this is also more in line with the contemporary common use of the term 'sport'. This paper discusses these 'ultra/nature' sports, mainly from the point of view of their relationship to nature, the values that they offer to athletes, and their specific temporality.

In this article, I will examine the role of risk in the risky nature sports. Risky nature sports are identified as nature sports where participants may reckon with the possibility of severe injury or death if things go wrong. The first part of the article identifies some evolutionary, historical, and conceptual characteristics of nature sports and risk. In the second part of the article, I discuss the concept of risk and its meaning in risky nature sports. Additionally, I address questions concerning the moral tone and context of risk-taking. In most academic disciplines, risk is typically understood as something negative that should always be avoided. But risk also includes positive possibilities, which may, such as in risk sports, outweigh the negative or can even be inherently positive and a value in itself. In the third part, I discuss how important risk is in nature sports. Is it a defining core or more peripheral? This leads to the question of the value. Does the risk element add to the value of the sport? I finally discuss how risk sports can be meaningful parts of the participants' lives. [ABSTRACT FROM AUTHOR]

Athletes, both amateur and professional, often resort to the consumption of nutritional supplements without professional supervision and without being aware of the risks they may entail. We conducted an exhaustive literature search to determine the most common substances found as contaminants in dietary supplements. For each substance, we analyzed its mechanism of action, clinical indication, health risk, and putative use as doping agent. In addition, we evaluated the current regulation of these supplements. Contamination of nutritional supplements (accidental or intentional), especially with steroids and stimulants, is a hazardous situation. The prolonged consumption of these products without being aware of their composition can cause serious health risks and, in the case of professional athletes, a possible sanction for doping.

An extensive literature base has investigated women's underrepresentation in decision-making positions with sport organizations, yet women's access to these positions remains limited. Diversification strategies, based on distributive justice, have failed to create further opportunities. A new approach is needed to address this latent issue. The concept of gender allyship is presented to address the limitations of distributive justice paradigms that involves men and women to work as members of a coalition to improve gender equity in sport organizations. Utilizing grounded theory, this paper presents the core category of awareness and related subcategories self-awareness, organizational awareness, and industry awareness, as a means of informing the performance of gender allyship. The findings provide interesting theoretical and empirical implications for understanding the development of awareness, its subcategories, and how it contributes to change. [ABSTRACT FROM AUTHOR]

Background: LGBTQ+ youth engage in organized physical activity to a lesser degree than their cisgender and heterosexual counterparts. Existing literature on this organized physical activity disparity is limited, particularly with LGBTQ+ youth samples. The current analysis examined individual and systemic barriers to organized physical activity for LGBTQ+ youth across sexual, gender, and racial identities. Methods: A subsample of LGBTQ+ students (N = 4566) from the 2021 Dane County Youth Assessment completed items that measured barriers to organized physical activity and systemic factors (ie, family money problems and bias-based bullying) associated with access to organized physical activity. Latent class analysis discerned patterns of individual and systemic barriers to organized physical activity. Latent class regression modeling tested gender, sexual, and racial identities as correlates of latent class membership. Results: More than half of the sample did not participate in organized physical activity. Four profiles of LGBTQ+ youth were discerned based on self-reported barriers: high barrier (8%), bullied (16%), low interest or perceived skills (28%), and low barrier (48%). The low-barrier class included a greater proportion of LGBTQ+ youth who identified as White, or cisgender, or heterosexual as well as youth self-reporting higher organized physical activity. The high-barrier and bullied classes comprised more marginalized gender and sexual identities. Conclusions: LGBTQ+ youth experience individual and systemic barriers to organized physical activity, including inequitable access and bullying, and barriers are uniquely experienced across sexual, gender, and racial identities. Physical activity promotion among LGBTQ+ youth would be strengthened by policies that address inequitable access to opportunities and bias-based bullying. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to examine whether, drawing on the perception of their coaches, the application of the pedagogical model of sport education could be associated with satisfying the basic psychological needs of children from socially vulnerable backgrounds. Method: A 36-session sport education season was implemented within a community program for youths from disadvantaged environments. Three coaches, one researcher, and 31 children aged 9–11 years (17 boys and 14 girls) of diverse ethnicities participated. Qualitative data were obtained through four focus groups conducted during the program in addition to the research diary of the researcher, who played the role of participant observer. Results: The coaches observed a progressive evolution in the satisfaction of the basic psychological needs of competence, autonomy, relatedness, and the need referred to as novelty. Discussion/Conclusion: We may conclude that sport education can be a valuable tool to improve the satisfaction of these needs in children from socially vulnerable backgrounds. [ABSTRACT FROM AUTHOR]

In consideration of sport mediatization, mobile media, and fandom, this work introduces and outlines the phenomenon of parasocial pretend play. This is achieved by examining the popular television show Ted Lasso, which chronicles the activities surrounding fictional English football club AFC Richmond. Viewer involvement with the show, parasocial interaction with its characters, and social media use by connected fans combine to facilitate this new opportunity for playful collective engagement. By connecting concepts from parasocial interaction and play, the assessment theorizes about and documents how parasocial pretend play transpires. It also identifies factors that may disrupt parasocial pretend play, discusses the potential for its misuse, and details apparent variations of the practice. [ABSTRACT FROM AUTHOR]

This study analyzed media framing of athletes who have suffered mental ill health. The mass media play a crucial role in shaping public attitudes and perceptions surrounding mental health, and the present study aimed to examine the media reporting of athletes' mental ill health and to further explore how this reporting has changed over time. We examined the reporting of elite athletes in three U.K. media outlets between January 2000 and December 2019, identifying 75 athletes from 26 different sports. From analysis, four themes were developed to consider the content of media reporting and how it has changed over three time phases. The analysis revealed that media reporting of mental ill health has increased over time, and changes were observed in terms of the specific terminology used, with greater depth in the articles, such as journalists speaking to other professionals to construct the articles. This study contributes toward our growing understanding of the reporting of mental ill health by providing empirical evidence of the increased attention to the topic and increasingly responsible reporting in the media.

Purpose: This study aimed to cross-validate a recently proposed equation for the prediction of maximal oxygen uptake ( V ˙ O 2 max) in cycling exercise by using the average power output normalized by the body mass from a 5-minute time trial (RPO5-min) as the independent variable. Further, the study aimed to update the predictive equation using Bayesian informative prior distributions and meta-analysis. Methods: On different days, 49 male cyclists performed an incremental graded exercise test until exhaustion and a 5-minute time trial on a stationary cycle ergometer. We compared the actual V ˙ O 2 max with the predicted value obtained from the RPO5-min, using a modified Bayesian Bland–Altman agreement analysis. In addition, this study updated the data on the linear regression between V ˙ O 2 max and RPO5-min, by incorporating information from a previous study as a Bayesian informative prior distribution or via meta-analysis. Results: On average, the predicted V ˙ O 2 max using RPO5-min underestimated the actual V ˙ O 2 max by −6.6 mL·kg–1·min–1 (95% credible interval, −8.6 to −4.7 mL·kg–1·min–1). The lower and upper 95% limits of agreement were −17.2 (−22.7 to −12.3) and 3.8 (−1.0 to 9.5) mL·kg–1·min–1, respectively. When the current study's data were analyzed using the previously published data as a Bayesian informative prior distribution, the accuracy of predicting sample means was found to be better when compared with the data combined via meta-analyses. Conclusions: The proposed equation presented systematic bias in our sample, in which the prediction underestimated the actual V ˙ O 2 max. We provide an updated equation using the previous one as the prior distribution, which could be generalized to a greater audience of cyclists. [ABSTRACT FROM AUTHOR]

Context : In March 2020, public health concerns resulted in school closure throughout the United States . The prolonged sport cessation may affect knee injury risk in high school athletes. The purpose of this study was to describe and compare risk of knee injuries in high school athletes during 2019-2020 and 2020-2021 academic years, and stratify by gender, severity, mechanism of injury, injury type, and knee anatomic region . Design : Historical-prospective cohort study . Methods : This historical- prospective cohort study included 176 schools in 6 states matched by sport participation in control and COVID years from July 1, 2019 to June 30,2021. Injury rates per 1000 athletes per year were calculated with 95% confidence intervals. A negative binomial regression was performed to assess potential differences in knee injuries between academic years . Results: 94, 847 and 72,521 high school athletes participated in the 2019-2020(19-20) and 2020-2021 (20-21) seasons. Knee injury risk was higher in the 20-21 season (19-20: 28.89% [27.82-29.96-]; 20-21: 33.82% [32.50-35.14]). Risk increased for male athletes from 2019- 2020 to 2020-2021 (19-20: 29.42% [28.01-30.83]; 20-21 : 40.32% [38.89-41.75]). Female knee injury risk was similar between years (19-20: 25.78% [24.29-27.27]; 20-21: 26.03% [24.31-27.75]). Knee injuries increased by a ratio of 1.2 ([95% CI, 1.1- 1.3], P <.001) during 2020-2021. Conclusions,· Knee injury risk and relative risk increased among males in 2020-2021. Results indicate changes in knee injury risk following return from COVID shelter in place among high school athletes and implicate potential negative downstream effects of interrupted sports training and participation on high school injury risk.

Traditional games are often situated in counter distinction to modern sport forms and are not well understood in Western society or scholarship. However, from these games, we have the opportunity to learn much about local play and physical culture. This article focuses on traditional Indigenous games in Oceania and how they can be used as a lens for the development of environmental stewardship or ecological sensibilities. The aims of this study are twofold: (1) to lay a foundation for future research in this area and (2) to situate traditional games within the broader sport ecology conversation. By deconstructing the embodied nature of traditional games and overviewing the histories of environmentalism in Oceania, a more grounded claim can be made for the relevance of traditional games within sport and leisure studies scholarship, including sport history, sport sociology, sport anthropology, and sport ecology. The nature games of Oceania yield diverse insights into Indigenous epistemologies, ecological sensibilities, and how outdoor play can be understood as a form of climate action.

Sports associations have a special relationship with natural landscapes. In the second half of the twentieth century, a number of organizations positioned themselves as defenders of the natural environment against the development of tourism and sports leisure facilities. They attempted to tackle the problem of over-equipment of natural areas. This research is based on a study of two outdoor institutions, the Centre Nautique des Glénans (CNG) and the Club Alpin Français (CAF). Despite their different pasts and proposed activities, both have been involved in landscape and environmental protection throughout their history. This can be seen in the way both associations integrate their facilities into the landscape, as well as in the work they do to raise their members' awareness of environmental preservation as part of their sporting activities.

Purpose: The aim of this systematic review is to reveal the social, personal, and contextual factors that influence physical activity (PA) in children and adolescents during and after cancer treatment. Method: SPORTDiscus, Cochrane, Web of Science, PubMed, and FIS Education electronic database were systematically searched. Results: The 13 included studies show that social support (parents, siblings, and friends) in particular is rated as important by cancer survivors; for example, doing PA together. Depending on the treatment status and state of health, particularities arise. During the acute treatment phase, parents issued more prohibitions regarding PA than after treatment. The state of health and concern about infections are described as inhibiting factors. Not all hospitals generally offer special exercise programs for cancer patients, and in some cases, only sporadic exercise sessions were conducted by specialized staff. In addition, the hospital atmosphere, such as cramped rooms, tends to be associated with demotivating effects. Conclusions: Both inhibiting and promoting factors in the area of social, personal, and contextual factors could be identified. The most fundamental factor for PA is the physical condition. Social factors, such as parents or friends, often have a motivating effect and can promote PA. Inhibiting factors are mainly context-related, such as an environment unsuitable for PA. Although the review highlights interesting aspects, further treatment-related and longitudinal studies could provide deeper insights. [ABSTRACT FROM AUTHOR]

Purpose: The monitoring of training loads and quantification of physical performance are common practices in youth soccer academies to support coaches in prescribing and programming training for individuals. The interaction between training load and physical performance is unknown during a preseason period in youth soccer players. The current study assessed changes in training load and physical assessments across a 4-week preseason period. The relationship between physical performance and match playing time in youth male soccer players was also investigated. Methods: The training loads of 25 professional youth academy male soccer players were monitored throughout a 4-week preseason period. Assessments of power, agility, speed, and aerobic capacity were undertaken in the first training session. Session ratings of perceived exertion (sRPE) and well-being questionnaires were collected during all training sessions and preseason matches. Playing time during subsequent competitive matches was recorded. Results: T test and 30-m-sprint assessments, conducted on the first day of preseason, were predictors of sRPE throughout preseason (t test χ2/df = 2.895, poor adjustment; 30-m sprint χ2/df = 1.608, good adjustment). YoYo Test performance was related with changes in perceived fatigue (χ2/df = 0.534, very good adjustment). Faster players reported higher values of sRPE, and players with higher aerobic capacity reported higher levels of fatigue across preseason. Well-being, perceived fatigue and soreness, and sRPE decreased across preseason. Greater match durations were related to higher levels of fatigue during preseason (P <.05). Conclusion: The current study highlights the relationship between training load, physical assessments, and playing time. Coaches and practitioners can use physical test data at the start of preseason as an indication of players that report higher sRPE, perceived fatigue, and reduced well-being across preseason, supporting decisions around individualized training prescriptions.

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]

Researchers have studied human perception-action systems during interceptive tasks in real or virtual situations. Training and practice may enhance perception and action in dynamic gap interception tasks like crossing a road. For relevant studies, we thoroughly searched PubMed, PsycINFO, ScienceDirect, ResearchGate, and SPORTDiscus. We reviewed and summarized research to determine how task-specific practice, exercise, and sports experience affect perception-action capacities when intercepting a moving gap. Specifically, we examined how sports experience influences perception-action coupling in street crossing. Task-specific and sports skills may improve perception-action in everyday activities. Hence, task-specific practice and perception-action coupling in sports may increase perceptual-motor skills for dynamic gap interception tasks. [ABSTRACT FROM AUTHOR]
