Yet, the impact of iron deficiency on physical capacities beyond endurance is not clear.Purpose: The purpose of this study was to assess variations in seasonal micronutrient concentrations and how iron deficiency impacts external-load measures in elite female rugby league players.Methods: Iron and vitamin D status were measured in 28 players (age 24 [4] y, body mass 76 [11] kg) across 3 time points of the 17-week National Rugby League Women's season. Physical demands were evaluated using external-load measures (eg, total distance, PlayerLoad) for training and competition. Linear mixed-effects models were employed to assess the effect of change in serum ferritin concentration on external-load measures. Effect sizes with 95% CIs were calculated to interpret the magnitude of difference in change in indices and performance outcomes between iron-deficient and iron-sufficient players.Results: Iron-deficiency prevalence ranged from 26% to 57% across the season, and <22% of players were vitamin D deficient at each time point. Weak to strong positive associations (R2 = .3-.6) were observed between all external-load measures and moderating variables (serum ferritin, week, position, and athlete). However, these associations were largely attributable to the contribution of week and position. Differences in load measures between iron-deficient and iron-sufficient players were mostly trivial to small.Conclusions: Iron status of elite female rugby league players had little effect on most workload measures within this cohort. However, longitudinal monitoring is warranted to identify how external-load measures are affected individually in response to fluctuations in serum ferritin.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"411-419"},"PeriodicalIF":3.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to evaluate the reliability of countermovement-jump (CMJ) velocity-load testing and assess the relationship between CMJ velocity-load kinetics and concentric-isometric-eccentric multijoint leg-extension strength tested on a robotic servomotor leg press in trained athletes.Methods: University athletes (N = 203; 52% female) completed 3 concentric, isometric, and eccentric maximum voluntary leg-extension contractions on the robotic leg press, followed by CMJ velocity-load testing with an additional external load of 0% (CMJBW), 30% (CMJ30), and 60% (CMJ60) of body mass. A linear model was fit for the CMJ takeoff velocity-load relationship to obtain the load intercept. Force-velocity parameters were obtained for the CMJ eccentric deceleration and concentric phases. Linear mixed-effects models were constructed to predict concentric, isometric, and eccentric leg-press force using the CMJ takeoff velocity-load relationship and CMJ kinetics.Results: Isometric leg-press strength was predicted by load intercept and sex (P < .001, R2 = .565, prediction error = 14%). Concentric leg-press strength was predicted by load intercept, CMJ60 concentric impulse, and sex (P < .001, R2 = .657, prediction error = 10%).

This study assessed the impact of a WC episode on dietary and appetitive profiles in athletes, considering sex and sport type.Methods: Athletes (28 male, 20 female) from combat (n = 23), strength (n = 12), and endurance (n = 13) sports participated in 3 conditions during a WC episode (baseline, WL, WG). Measurements included body composition (dual-energy X-ray absorptiometry), energy intake (48-h food record), appetite (visual analog scale), dietary profile (questionnaires), and food reward (computer task).Results: Overall, athletes lost 4.4% (2.3%) of their body weight and regained 4.5% (2.9%) (P < .001). Energy intake decreased during WL (P < .001) with a higher protein intake (% of energy intake) before returning to baseline in WG (P > .05). WL increased hunger, prospective food consumption, and desire to eat compared with the baseline condition, but these changes were not seen in WG. Liking and wanting for fat and sweet foods were higher during WL and remained elevated in WG (P < .05). No eating disorders were found during the WC episode, but combat-sport athletes and females had a higher binge-eating risk than others, independent of the condition.Conclusions: Moderate WC episodes do not seem to impair appetite responses in athletes experienced with WC, likely due to their maintaining high physical activity levels. However, their long-term eating-behavior traits, especially in combat and female athletes, seem negatively affected. Practitioners should consider the long-term impacts of these WC practices on nutritional health.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"372-384"},"PeriodicalIF":3.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental groups followed a PT program twice weekly for 6 weeks, with BG and UG performing 2- and 1-legged jumps, respectively. Both groups completed the same number of vertical, horizontal, cyclic, and acyclic jumps. Pretraining and posttraining measurements included (1) countermovement jump (CMJ), (2) unilateral CMJ (CMJL and CMJR), (3) horizontal jump (HJ), (4) unilateral HJ (HJL and HJR), (5) straight-line sprint in 20 m (T20), and (6) V-Cut COD test (V-Cut).Results: CMJ, CMJL, and CMJR were significantly improved by BG and UG (P < .001), while CG did not change. Both the BG and the UG improved their performance significantly (P < .01) in HJL and HJR, but only BG significantly increased (P < .05) HJ and showed significantly greater improvements than CG. Furthermore, only BG improved V-Cut performance (P = .03). Neither group increased T20.

Percentage of critical swimming speed (CSS), stroke rate, stroke length, jerk cost, stroke index, and mechanical proficiency score were computed by lap. Athletes were divided into groups of pacing effectiveness based on optimal potential performance level (OPPL)-optimal (nearOPPL) and suboptimal (farOPPL)-using functional clustering of percentage of the CSS. Race sections were analyzed with a change-in-slope detection method. Common stroke-regulation abilities and deviations by pacing groups were profiled by fitting hierarchical generalized additive models between mechanical variables and laps.Results: The 2 clusters were discriminated by percentage of the CSS sustainment (P < .01). Optimal performers showed a +41.4% more stable pacing (2 race sections vs 3 for farOPPL) and a +36.7% higher end spurt, with a trend combining higher overall stroke rate (P = .08) with lower jerk cost (P = .17). Functional profiles showed that maintaining a higher stroke length and stroke index in a fatigued state, rather than overall values, allows the swinner to reach OPPL (P < .001). High regulation of mechanical proficiency score across the race, in line with pacing expectations of particular race sections, is a game changer to sustain CSS (P < .001).Conclusions: Specific profiles of stroke regulations, regarding tradeoff between stroke smoothness and resultant speed, lead to optimal pacing during the 5000-m.

The demanding nature of squash results in substantial metabolic heat production, with consequential heat strain exacerbated by the indoor environment of squash courts, where low to moderate evaporative potential limits effective cooling. Players often experience increased body-heat storage and thermal strain, with muscle cramps (an early warning sign of more severe heat-related illnesses) commonly observed during tournaments. Despite these challenges, there are limited data on the thermoregulatory responses of elite squash players during match play.Purpose: We discuss the thermoregulatory challenges faced by squash players and highlight key areas for research. Additionally, practical guidelines are provided for practitioners preparing squash players for the Los Angeles 2028 Olympics.Evidence: Preliminary findings from international squash tournaments reveal that elite players endure significant physiological strain, with core temperatures rising to 39.0 °C to 40.1 °C, despite matches being played in mild wet-bulb globe temperatures of 19.4 °C (0.9 °C). Sustained heart rates exceeding 90% of maximal heart rate further compound this thermal strain. However, research on how thermal strain affects squash-specific fitness, recovery, and stroke mechanics are lacking. Such information is crucial for evaluating the need and effectiveness of tailored mitigation strategies such as heat training/exposures and precooling and midcooling during warm-up and match play.Conclusion: Systematic research into the thermal demands of squash and their impact on fitness and skills is needed. These insights can inform evidence-based strategies to safeguard athlete well-being and optimize performance at Los Angeles 2028.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-4"},"PeriodicalIF":3.5,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to determine the impact of the maximal unilateral isometric strength of the ankle PF muscle and reactive strength on sprint acceleration performance.Material and methods: Thirty-two male floorball players (mean [SD] age 20.3 [3.0] y, height 181.5 [8.5] cm, body mass 77.4 [12.2] kg, and body mass index 22.3 [2.8]) from 2 clubs in the highest division in Latvia performed 20-m linear sprint, unilateral 10/5 repeated jump (reactive strength index [RSI]), ankle-dorsiflexion range of motion, and isometric seated plantar-flexion strength tests, where all data were used for correlational analysis.Results: Unilateral RSI was associated with 20-m sprint time (r = -.52, P < .01) and average speed from 10 to 20 m (r = .72, P < .01). Relative PF strength was associated with unilateral RSI (r = .35, P < .05) and 20-m sprint time (r = -.36, P < .05), whereas ankle-dorsiflexion range of motion was associated with unilateral RSI jump height (r = .47, P < .05).Conclusions: Floorball athletes with higher unilateral RSI and isometric PF muscle strength tend to accelerate faster, but subjects with better ankle-dorsiflexion range of motion jump higher in vertical repeated jumps. These findings suggest that both reactive and isometric strength are key indicators for sprint acceleration performance in floorball athletes, providing coaches with tools to monitor and improve performance.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"393-398"},"PeriodicalIF":3.5,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While laboratory studies have provided valuable insights into the acute effects of MF, their ecological validity in real-world sport settings remains limited. Recent research indicates that MF can naturally arise during sport activities, leading to chronic effects on endurance and perceptual-cognitive skills. These effects may persist beyond individual sessions, potentially increasing the risk of injury due to their cumulative nature.Purpose: This commentary aims to guide future research by emphasizing the need to investigate the natural occurrence and chronic effects of MF in applied sport settings.Conclusions: Understanding how MF develops and manifests in real-world settings, particularly individual differences in perception and response, is crucial for creating more effective management strategies. Addressing these factors will enable better support for athletes who may experience prolonged periods of MF that could affect their training and competitive performance. Future research should prioritize studying MF in natural sport settings to enhance the ecological validity of findings. By focusing on the chronic and cumulative nature of MF, as well as individual variability, researchers can develop more tailored and effective strategies for managing MF. This research will not only bridge the gap between laboratory studies and real-world applications but also contribute to more precise monitoring and intervention techniques. Ultimately, these advancements will improve athletes' ability to maintain peak performance and reduce the risk of injury, thereby enhancing overall athletic well-being.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-5"},"PeriodicalIF":3.5,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One study showed significant agility improvements after an intervention including core training for athletes with groin pain. However, it is unclear if these improvements resulted specifically from the core exercises or the entire program. Additionally, the study lacked a control group, making the findings inconclusive.Purpose: The current study aimed to explore the effect of core training, previously reported in the context of groin-pain rehabilitation, on agility performance in soccer players with groin pain.Methods: Twenty soccer players with groin pain volunteered to participate. They were randomly assigned to a core training group (n = 10) and a control group (n = 10). Before and immediately after that period, agility performance (T test and Edgren Side Step Test) and self-reported outcomes (Copenhagen Hip and Groin Outcome Score) were assessed in both groups.Results: No significant session × group interaction was observed in agility T test (F = 2.55; P = .12; ηp2=.12) and Edgren Side Step Test (F = 3.18; P = .09; ηp2=.15) performances.
