This sport has particular balls that require different hitting styles, like hitting dinks. This study focuses on introducing pickleball players' kinematic analysis through a MediaPipe-based deep learning (DL) tool and analyzes the dominant leg's femur angle, knee angle, and wrist motion of pickleball players during the hitting dink shots, comparing pickleball players with high-level and beginner levels. Fourteen male pickleball players (aged 46.5 ± 10.5) participated in performing a dink shot during warm-up while being recorded by a GoPro camera and analysed by the DL tool. Statistical analysis, including T-tests and One-way ANOVA, showed significant differences between athletes and non-athletes in femur angle during the dink shot (p < 0.001), where high-level athletes demonstrated more femur flexion. Knee angles did not differ significantly, but advanced athletes maintained continuous wrist motion after the ball hit (p < 0.001). The MediaPipe-based DL tool estimated joint angles and motion patterns, offering an approximate alternative to visual analysis by coaches. With the developed DL tool, the coaches and players can rapidly monitor kinematics parameters and identify improvement areas. Future studies should further investigate foot positioning and trunk rotations in different shot types to assess pickleball biomechanical behaviours.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1860-1870"},"PeriodicalIF":2.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144497401","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}

This study aimed to develop and validate a multidimensional prediction model for overtraining risk in youth soccer players by integrating physiological, psychological, and performance parameters through advanced machine learning. A longitudinal study tracked 120 male youth players (aged 12-18) from six elite South Korean academies over one competitive season (August 2023-May 2024). Data included bi-weekly blood sampling (testosterone, cortisol, creatine kinase, IL-6, TNF-α), weekly psychological assessments (RESTQ-Sport, POMS), continuous GPS-based training load monitoring, and monthly performance tests. A random forest model with SMOTE to address class imbalance achieved an AUC-ROC of 0.94 (internal validation), with sensitivity and specificity of 0.87 and 0.92, respectively. Key predictors included testosterone-to-cortisol ratio (0.89), RESTQ-Sport balance (0.83), and acute:chronic workload ratio (0.78). A simplified, non-invasive model excluding blood markers achieved an AUC-ROC of 0.89. A three-tier risk stratification system identified 85% of high-risk cases a week before performance declined. These findings underscore the model's superior predictive power and practical utility, offering a foundation for evidence-based, proactive overtraining risk management in elite youth soccer development.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1819-1834"},"PeriodicalIF":2.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144369014","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}

We observed larger performance gaps in upper-body dominant disciplines (KAY ~14%, CAN ~ 20%) than in the lower-body dominant CYC (~11%). Notably, in CAN - where women's elite-level inclusion has been more recent - performance gaps were both larger and continued to narrow over time. In contrast, KAY and CYC showed relatively stable differences, aligning with longer histories of women's participation. These findings suggest that observed size and stability of performance gaps reflect both physiological sex differences and the influence of sport-specific development pathways and access. Monitoring performance trajectories across both sexes may provide insight into whether sex differences reflect biological ceilings or are shaped by contextual inequities in opportunity and support.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1885-1894"},"PeriodicalIF":2.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144591523","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}

Findings indicate that key facilitators included social support from parents, friends, and support staff within rugby, as well as participants' enjoyment of the game, underpinned by the inclusivity of the sport, all of which contributed to both initial and continued participation. In contrast, barriers included stereotypes associated with the sport, time constraints, limited access at school, and challenges surrounding access to rugby opportunities linked with geographical location and education.

Stability and variability were represented by total displacement and the standard deviation respectively of translational motion of pistol endpoint in the mediolateral, anteroposterior, and vertical directions. Independent t-tests compared trigger pull force and motion characteristics between groups, while Pearson's correlation assessed their relationship. Sub-elite shooters showed a significant drop in Normalized Trigger Pull Force 0.15s after firing, while elite shooters maintained their force level, indicating follow-through of the trigger pull as a high-level technique. Total Normalized Trigger Pull Force Variation was moderately to highly correlated with pistol stability in the three directions (r = 0.56 ~ 0.70) and vertical variability (r = 0.72) during the total-shot period.
