However, little is known about how coach behaviors that span the full range leadership model (i.e. FRLM) impact development. In this study, we asked whether FRLM coaching behaviors promote positive development outcomes and mitigate negative experiences in the university sport context and whether these effects are mediated by perceptions of a quality coach-athlete relationship. In total, 605 Canadian university athletes (<i>M_age</i> = 20.09 <i>SD</i> = 1.74) completed the Multifactor Leadership Questionnaire, the University Sport Experience Survey, and the Coach-Athlete Relationship Questionnaire. Mediation analyses assessed the explanatory role of athletes' perceived coach-athlete relationship in associations between coaches' leadership behaviors and athletes' reports of personal developmental outcomes and negative experiences. The coach-athlete relationship was positively associated with positive development outcomes in university athletes (i.e. initiative, basic skills, interpersonal relationships, teamwork and social skills, and adult network and social capital) and inversely associated with negative experiences (i.e. stress, negative peer interactions, social exclusion, and negative leadership). Findings only partially supported the assertion that transformational leadership promotes positive development and reduces negative experiences by enhancing the coach-athlete relationship. The results support benefits of transformational coaching when targeting positive development, similar to youth sport, but suggest the coach-athlete relationship has little explanatory value when examining associations between coach leadership and positive development outcomes in university sport. Instead, the coach-athlete relationship does help account for the mitigation of negative experiences in the university sport context.</p>","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-11"},"PeriodicalIF":1.6,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify the most important predictors of daily and match-day fatigue in six Italian professional soccer teams during a competitive season using a framework of big data analytics. Every morning, the players rated fatigue, sleep quality, muscle soreness, stress, and mood. After each training session or match, the session Rating of Perceived Exertion was obtained and multiplied by duration to calculate the training load (TL). A framework of four machine learning models (Decision Tree classifier, XGBoost classifier, Random Forest Classifier, and Logistic regression) was trained and tested on 30.211 examples (one full season of six teams) to assess their ability to predict the players' match-day fatigue. The machine learning models accurately predicted the players' subjective fatigue (models' range accuracy 70-82%). Specifically, in the prediction of match-day fatigue, stress, and mood of the previous day were the most influential factors. Mediation analysis unveils the relationship between TL of the day before the match and the perception of match-day fatigue, also mediated by mood and muscle soreness.

Latent profile analysis (LPA) categorized preschoolers into distinct profiles based on their AMC and PMC. The analysis included 571 children aged 3-6 years from a large rural, publicly funded early childhood center in the southeastern United States. Data on AMC were collected using the Test of Gross Motor Development-3 (TGMD-3), while PMC was assessed through a modified Pictorial Scale of Perceived Movement Skill Competence (PMSC). EF was evaluated using the NIH-Toolbox Cognition Battery, focusing on inhibitory control and cognitive flexibility. Auxiliary variable methods were used to examine the relationships between the profiles and covariates, including age, gender, race/ethnicity, and EF. Five distinct profiles were identified, revealing varying levels of alignment between AMC and PMC. Significant associations were found between these profiles and EF components. Children with more accurate self-perceptions of their motor competence exhibited higher EF levels, particularly in cognitive flexibility and inhibitory attention. Results from this study underscore the importance of fostering accurate self-assessment in young children to support both motor and cognitive development. Thus, early childhood education programs should integrate activities that promote realistic self-evaluation of motor skills, which may enhance EF and contribute to healthier developmental trajectories.</p>","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-11"},"PeriodicalIF":1.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145042867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One hundred thirty-two male elite academy soccer players between 13 and 20 years old (16.3 ± 2.2 years; body mass (BM): 68.8 ± 6.5 kg; height: 174 ± 7 cm) competing in the Argentinian Football League participated.

This idea means that, in sports like soccer, the playing area encapsulates an ecological niche, replete with affordances inviting collective and individual technical-tactical actions, contextualized with associated psychological and physical demands. To examine the co-adaptive relationships framing players' actions in their ecological niche, the present study employed a crossover design with repeated measures to compare the players' transactions within 11 vs. 11 training games across four different field dimensions (from official size to a small-sided game). Player transactions with the performance environment were analyzed across 40 game sequences, using 10Hz GPS positional data. Metrics such as convex hull dimensions, field occupancy, and proximity to opponents were derived. Repeated-measures ANOVA revealed significant differences between tendencies for forming synergies constrained by field dimensions scaling. When field size was reduced, the convex hull dimension significantly decreased. Additionally, relative field occupancy and distance to nearest opponent exhibited significant changes, especially when contrasted with performance transactions emerging on the official size field. These observations underline the essential functional relationship between the playing field dimension and emergent player actions. Such findings underscore the need for soccer coaches and training designers to integrate the specificity of field dimension scaling in training designs to represent competitive performance contexts.
