KT was applied using an inhibition technique on rectus femoris, vastus medialis, biceps femoris, and lateral gastrocnemius muscles of the dominant leg. A single-leg CMJ test and sEMG activity were recorded at baseline (no tape), as well as at 1 hour, 24 hours, and 48 hours after taping. To induce acute neuromuscular fatigue, a 30-second repetitive CMJ test was used to evaluate KT in fatigued states. In the resting states, both groups exhibited improvements in jump height, power, mean velocity, and sEMG activity (%EMGmax) over time, with no significant between-group differences. The single-leg CMJ performance was similarly decreased after the muscle fatigue protocol in both groups, showing no between-group differences.

This study sought to explore this relationship. Kinematic data were collected for 77 collegiate pitchers. Fifty-seven kinematic parameters were included in path analyses for horizontal and vertical plate locations. Release angles were set as mediating variables (MED) between independent and dependent variables. Eleven kinematic variables directly (13 indirectly) affected the vertical plate location, while 23 kinematic variables directly affected the horizontal plate location (10 indirectly). Linear mixed models revealed that lateral trunk flexion at ball release (R 2=0.908, BIC=-598, ICC=0.528) best explained vertical plate location. Trunk flexion at foot contact (R 2=0.944, BIC=-607, ICC=0.776), mediolateral center of mass displacement at foot contact (R 2=0.974, BIC=-573, ICC=0.918) and ball release (R 2=0.967, BIC=-593, ICC=0.865), and pelvis rotation at ball release (R 2=0.965, BIC=-588, ICC=0.895) models were identified for the horizontal plate location. Results indicate that the relationship between pitching kinematics, release conditions, and throw location is complex. Biomechanics can influence release parameters, which in turn impacts the throw location. This work may serve to understand better how biomechanics influence performance.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142620681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incremental load tests were conducted to assess the symptomatic limit on separate days under normoxic and hypoxic conditions (oxygen concentration 15.4±0.8%) using an ergometer. The initial test environment was randomized. The peak oxygen uptake and blood lactate were monitored every minute, and Δ peak oxygen uptake (peak oxygen uptake under hypoxia - peak oxygen uptake under normoxia) was calculated. Sixteen genotypes linked to exercise tolerance (such as angiotensin-converting enzyme [ACE]) were examined. Peak oxygen uptake significantly decreased under hypoxia (p<0.01). Δ peak oxygen uptake varied among individuals (minimum: 0.7 and maximum: - 18.9). Among analyzed genetic polymorphisms, ACE-II genotypes showed significantly greater Δ peak oxygen uptake than ACE-ID/ACE-DD genotypes (p=0.02). ACE-II genotypes exhibited lower blood lactate elevation at peak exercise in normoxic (p=0.01) and hypoxic (p=0.03) conditions.

Sports and exercise science research have investigated the effects of experimentally induced mental fatigue on cognitive performance, with mixed results. It has been suggested that negative effects of mental fatigue on cognition performance in laboratory studies could translate to impaired sport performance. However, it remains unclear if impairments in sport performance are due to mental fatigue and how mental fatigue may differ from physical fatigue. Fatigue is well understood as a complex multifactorial construct involving interactions between physiological and neuropsychological responses across brain regions. It may be prudent for researchers to return to the origins of fatigue and cognition before attempting to connect mental fatigue and sport cognition. This article reviews the concept of mental fatigue, its mechanisms and neuroanatomical basis, models of cognition relevant to sports science, how mental fatigue may influence cognition, and suggests future research directions. Mental fatigue as a construct separate from fatigue could be an oversight that has hindered the development of our understanding of mental fatigue. Future sports science research could work to enhance our knowledge of our definitions of fatigue.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
