However, it is unclear whether this relationship extends to adults. A two-phase cross-sectional study was conducted to examine whether physical literacy relates to physical activity in adults. In phase one, 225 participants reported their perceived levels of physical literacy using the Physical Literacy in Adults Scale (PLAS) and their physical activity behaviours using the International Physical Activity Questionnaire. In phase two, 59 participants wore an accelerometer to provide a device-based assessment of physical activity before completing the PLAS. A series of bivariate regressions were conducted to assess the relationship between physical literacy and physical activity. Physical literacy was a significant predictor of self-reported moderate to vigorous physical activity (MVPA) and total physical activity. However, scores on the PLAS did not predict light intensity self-reported physical activity. For device-based assessment of physical activity, physical literacy was a significant predictor of MVPA, but did not predict light or total physical activity. These findings indicate that physical literacy relates to physical activity, particularly MVPA. Differences in findings between self-report and device-based assessment warrant further consideration. Future research should continue to assess the role of physical literacy across physical activity types (e.g. leisure time, work related) and intensities.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"593-599"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143468327","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 aimed to explore potential determinants of subjective recovery in 101 male professional soccer players of 4 Italian Serie C teams and to further investigate whether the relationship between training load and subjective recovery is mediated by fatigue, sleep quality, muscle soreness, stress and mood. A complete season for each of the four teams was recorded for a total of 16,989 training sessions and matches. Every morning, players rated their perceived fatigue, sleep quality, muscle soreness, stress and mood, and judged their recovery using the Total Quality Recovery (TQR) questionnaire. Training load was obtained after each training session or match. A framework of data analytics of time series was employed to detect the factors associated with subjective recovery. Machine learning and mediation analyses suggest that TQR is primarily associated with ratings of fatigue and muscle soreness at the judgements time, and that these factors mediate most of the relationship between training load of the previous day and subjective recovery. These findings suggest that, to maximize subjective recovery, strategies minimizing fatigue and muscle soreness should be implemented. Reducing the training load of the previous day seems the most effective strategy.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"448-455"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143256102","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}

Organised sports participation and non-organised PA (outdoor time) were investigated via guardian questionnaire (T1, T2).

A linear regression model demonstrated that children's multisport participation at T1 predicted higher performance in LMS, OCS, FMS, and JS (p < 0.001 to p = 0.003; R2 = 16.4% to 23.5%) at T2. Outdoor time on weekdays at T1 predicted higher JS (p = 0.009, 8.4%), OCS (p = 0.006, 14.5%) and FMS (p = 0.003, 10.0%) scores for girls.

Fifteen elite youth players (16.7 ± 0.6 years) participated in a crossover study comparing four re-warm-up protocols following a standardized warm-up. Performance was measured immediately after warm-up and 15-min post re-warm-up using the counter-movement jump (CMJ), drop jump (DJ), and 5-0-5 change of direction test (CODs). Prolonged inactivity (CON) significantly decreased CMJ and DJ height (p < 0.001) and slowed CODs times (p = 0.019). Plyometric re-warm-up (PLY) preserved CMJ, DJ, and CODs performance (p > 0.05), while dynamic stretching (DYN) and passive heat maintenance (TOW) maintained DJ and CODs (p > 0.05) but reduced CMJ (p < 0.001). ANCOVA revealed a significant effect of re-warm-up strategies on CMJ (F = 20.71, p < 0.001, ηp2 = 0.54), with post hoc tests showing PLY was superior to other protocols (p < 0.001). These findings emphasize the effectiveness of plyometric strategies in maintaining physical performance during inactivity. Tailored protocols considering individual needs and basketball-specific demands can enhance player readiness and team success.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"536-543"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143441252","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}

The study investigated the relationship between strength, proprioception, endurance and range of motion of the cervical spine and impacts associated with heading the ball in adolescent male soccer players. The participants were 20 skilled players aged 15-18 years. Outcome measures included questionnaires, assessments of cervical spine function (range of motion, joint position error, isometric muscle strength and endurance) and the ratio of maximum head acceleration to maximum T3 acceleration (impact ratio) during each ball impact when heading the ball. Results showed that increased range of motion of extension of the cervical spine and lower joint position error in flexion of the cervical spine were associated with higher impact ratios. Greater isometric strength of the lateral flexors was associated with lower impact ratios. Endurance of the deep neck flexors was not associated with impact ratios. Strength training may be beneficial to decrease head impacts during soccer ball heading, especially in those with increased range of motion of extension of the cervical spine.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"512-522"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143468330","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}
