Y-intercepts for the IFR and MFR vs. RT relationships and N-EMGRMS increased during BFR (p < 0.05) collapsed across sex. The slopes for the IFR and MFR vs. RT relationships decreased during BFR (p < 0.05) collapsed across sex. The y-intercepts and slopes for the MUAPAMP vs. RT relationships were not different (p > 0.05) between treatments or sex. BFR during the 40% MVC increased IFRs, MFRs, and N-EMGRMS.

Data from 72 German national STSS athletes (33 female, 39 male) were analysed retrospectively. The statistical analyses included descriptive procedures as well as linear mixed-model analyses. The results showed significant correlations between WAnT outcomes and 500 -m performance of STSS athletes. In male athletes, the coefficients were -0.40 for relative Mean Power (rMP) and -0.32 for relative Peak Power (rPP) (p < 0.001). For female athletes, the rMP showed no significant correlation whereas rPP was significantly correlated with a coefficient of -0.41 (p < 0.001). Marginal R2 values ranged between 0% and 12%. Conditional R2 reached up to 76% depending on sex and WAnT parameter investigated. In conclusion while WAnT can be regarded as a potential predictor of time in 500-m STSS races, it should be used in conjunction with other performance metrics and individualized assessments to better predict performance.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1875-1879"},"PeriodicalIF":2.3,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142468485","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}

Using results from the 2016 and 2020 Paralympic Games, players' sport classes and in-competition key performance statistics (minutes played, throws per minute, goals per minute, penalties conceded per minute, blocks per minute, and goals per throw) were extracted. Players' visual acuity and visual field results were obtained through the IBSA Sport Administration System. Results showed no statistically significant differences in performance between classes. Further, there were no significant relationships between vision and performance for all six variables for female players. A small but significant positive correlation was found between visual acuity and the number of penalties conceded for male players. Collectively, the results suggest that currently eligible players compete fairly against one another during competitive goalball matches.

The results revealed greater RAE prevalence in youth compared to the senior group. RAE was more prominent in males compared to females, with the female group showing an inverse RAE trend. Odds ratio (OR) showed an overrepresentation of male boxers born in Q1 compared to Q4 (OR > 1.19-1.33), while senior female boxers presented an inverse trend (OR < 0.95). Odds Ratios for medallists within the youth group were greater than 1.07 (except Q3 × Q4 = 0.93) highlighting an overrepresentation of boxers born earlier in the year. A shift in strategy to reduce the RAE in young boxers whereby coaches focus less on the short-term pursuit of sporting success is encouraged.
