This study included 14 elite male volleyball players who participated in 95 training sessions and 18 matches. The session rating of perceived exertion and inertial measurement units were utilized to measure internal and external training loads, respectively. Biological recovery was assessed using the countermovement jump test, while social and psychological recoveries were measured through the RESTQ-Sport. Relationships were examined using linear mixed-effect models to account for repeated measures across players and time points. The results revealed that chronic external training loads negatively influenced the biological recovery, with increases in chronic external training loads associated with a longer time to take-off (β=- 0.008, p=0.03) and a reduced modified reactive strength index (β=- 0.008, p=0.047). Social recovery was influenced by internal training load metrics, with acute internal training loads increasing social stress (β=- 3.512, p=0.034). For psychological recovery, chronic internal training loads and the acute:chronic internal training load ratio were linked to higher emotional exhaustion (β=- 0.013, p=0.029; β=0.021, p<0.001, respectively). These findings highlight the critical role of external load management in the biological recovery and the relevance of subjective internal load measures in monitoring social and psychological recovery dimensions. Coaches are encouraged to integrate time-based neuromuscular metrics and perceptual load assessments into their recovery monitoring protocols to optimize athletes' well-being and performance.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"356-365"},"PeriodicalIF":2.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414080","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}

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.

CAI affects movement strategy during side-cutting maneuvers, with inconsistent results in many studies. This study aimed to clarify the characteristics of movement strategies during side-cutting maneuvers in female soccer players with and without CAI. Thirteen female soccer players with CAI and twelve healthy controls performed 10 successful trials of side-cutting maneuvers in three directions (anterolateral, lateral, and posterolateral) under unanticipated conditions. Compared to the control group, the CAI group displayed an increased stance time in the lateral and posterolateral side-cutting maneuvers (lateral: p=0.021, effect size=0.97, posterolateral: p=0.014, effect size=1.00). In posterolateral side-cutting maneuvers, the CAI group displayed a decreased posterior ground reaction force at 19-30% and 42-54% of the entire stance phase compared with the control group (p=0.001, effect size=1.30-1.42). Female soccer players with CAI may display increased stance time to compensate for self-reported ankle instability and may also exhibit decreased braking and propulsive force when side-cutting to sharper angles. These observations suggest a hypothesis that could help in the assessment of cutting maneuvers under unanticipated conditions after ankle sprains.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"217-223"},"PeriodicalIF":2.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142716185","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}
