The OptoGait system recorded speed, cadence and step length (variables that were also normalized in relation to height), running rate, contact phase, and flight phase. No significant sex-age interactions were found, and no significant differences were found between the sexes. Age significantly influenced all the parameters analysed. Children aged 3-6 years show the lowest values of contact time, particularly in initial contact time and toe-off time, compared to the other age groups, which additionally exhibited a higher cadence and shorter step length, even after normalization, in comparison with older children. Participants aged 13-17 years show the highest CV values for cadence and step length. In conclusion, age and running speed had a significant influence on spatiotemporal running parameters.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"544-554"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143557051","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}

Publication bias was assessed using funnel plots and statistical indices. Results showed that cognitively enriched PA and combined interventions had statistically significant but trivial effects on EF, with considerable variability. Specific PA subtypes, such as high-frequency, high-intensity activities and coordination games, resulted in small to moderate improvements in EF. PA interventions had a small significant impact on working memory, a trivial effect on cognitive flexibility, and no effect on inhibitory control. While both qualitative and quantitative elements in PA interventions produced statistically significant effects on EF, their practical significance was limited. This limitation persisted across specific PA subtypes. The study suggests future research focus on cognitively enriched activities to explore the various qualitative elements influencing cognitive function in these subtypes.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"565-579"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143449440","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 compared sleep quantity, quality, and architecture during home (no travel; HOME) and away (eastbound travel across three time zones; AWAY) matches in professional male rugby union. The sleep of twenty athletes was assessed using home-based polysomnography over three nights per condition: two nights preceding the match (MD-2), match night (MD), and the following night after (MD + 1). Sleep duration, efficiency, onset/offset, latency, wake after sleep onset, awakenings, and sleep stages (as light, deep and rapid eye movement [REM] sleep, evaluated as proportion [%] and time [min]) were monitored. Compared to HOME, AWAY increased sleep onset latency (+12 ± 23 min; p < 0.01) and reduced light sleep (-6.2 ± 7.1%; p < 0.01). Match days (MD) incurred delayed bedtime (+71 ± 135 min; p < 0.001), reduced sleep duration (-94 ± 120 min; p < 0.05), and altered sleep architecture (deep: +9.8 ± 10.0%; REM: -6.9 ± 8.3%; both p < 0.05) compared to MD-2.

Ground reaction forces and high-density EMG signals were collected from 19 males when leaning forward at 25%, 50%, and 75% of maximal forward leaning force. EMG amplitude increased with percent of leaning and was greater for SOL than FDB, but there were no differences in force fluctuations across tasks. Differences in motor unit activity indicated that the relative contribution of the two muscles to the control of balance varied across tasks as confirmed by the association between the fluctuations in neural drive [standard deviation of the filtered cumulative spike train (SD of fCST)] and force [coefficient of variation (CoV) for force]. Specifically, the correlation values were greater for FDB at the lower target forces. Correlation analyses revealed that synaptic noise (CoV for interspike interval) was weakly correlated with the CoV for force, whereas the variability in shared synaptic input (SD of fCST) was strongly correlated with the CoV for force. This finding suggests that the relative influence of the two muscles on the fluctuations in force during forward leaning varied with task requirements.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"468-476"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143256101","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}

Measurements were tissue hardness, pain pressure threshold (PPT) of knee extensors, knee flexion ROM, maximal voluntary isometric and concentric contraction before and after the intervention. PPT and knee flexion ROM were significantly increased in the FR_rolling and FR_KM groups, with no significant differences between the two groups. No significant changes were observed in tissue hardness, and muscle strength in all groups. Long-term interventions with FR_rolling and FR_KM could effectively increase knee flexion ROM and PPT similarly. Therefore, if difficulties from trunk stabilization or rolling during the FR-rolling occur, a simpler approach could be sustained through the FR_KM.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1-8"},"PeriodicalIF":2.3,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143523830","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}

Offensive metrics, such as shots on target (β = 0.21 WhoScored, β = 0.16 Sofascore, β = 0.17 FotMob, all p < 0.001), key passes, and successful take-ons had the highest impact, while defensive metrics like clearances (β = 0.12 WhoScored, β = 0.06 Sofascore, β = 0.12 FotMob, all p < 0.001) played a smaller but consistent role. Comparisons across rating systems revealed systematic differences, with WhoScored ratings significantly lower overall (β = -0.20, p < 0.001). These findings underscore that rating systems capture different aspects of player performance and are not directly interchangeable. The study highlights their potential for more systematic player evaluations in scouting and development while raising questions about transparency and biases.

Seven players (age: 23.1 ± 5.7 years; height: 1.82 ± 0.05 m; weight: 77.6 ± 10 kg) were evaluated. EMG outcomes included EMG amplitude, intensity distribution, and usual bout duration for dominant (D) and non-dominant (N.D) muscles. Hamstring activity averaged 47% (D) and 43% (N.D) of %EMGMVC, while quadriceps averaged 32% (D) and 27% (N.D). Most time was spent at the lowest EMG intensity and 13% at the highest intensity. Bout amplitudes (37-54%EMGMVC) and durations (14-17s) varied between muscle groups and limbs. The hamstrings' usual EMG bout amplitude (N.D) was the most sensitive, showing a 12% reduction (effect size [ES] = 0.64, p = 0,01).
