This study aimed to investigate the feasibility of a 10-week community-based program using the WalkWithMe (WWM) application in people with late sub-acute and chronic stroke in Benin. An interventional pilot study with mixed methods research design was used examining the application of an unsupervised individualized mobile Health (mHealth) instructed training program. Main outcome included the application usage, safety, adherence, perceived enjoyment, mHealth quality, patient experiences and pre-post efficacy measures. Nine adults, five males, median age of 60 years and time since stroke of 12 months participated in this study. For most participants adherence with the application was over 70%. However, some usability problems were observed due to incorrect understanding and use by participants and technical problems. The application was very fun, stimulating and enjoyable. Significant improvements were found with median (pre/post measures) of locomotors skill (1.4/3.4); impairments (38/40), Barthel Index (85/95), activity limitation (2.1/3.1), and quality of life (194/218). A trend towards significant improvement was found with 6 minutes walking test (181/220, p = 0.06). The WWM application is perceived as a potential approach to increase physical activity and functioning among people with stroke in Benin.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142468473","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}

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.

The 30-metre sprint time showed a small curvature but an accelerated increase around 12‒13 years old. However, the ball speed, swing velocity, and modified SEBT demonstrated a slower or less accelerated change in the developmental pattern starting around 12‒13 years old. Multivariate longitudinal analysis revealed that developmental change in athletic performance was positively associated with age and MB back throw.

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.

Current approaches, however, are narrow in scope by focusing on an inter-team allocation of space to measure space control. The present work extends this widespread perspective with an intra-team application of the Voronoi diagram and its dual Delaunay triangulation to measure space management. Both models are leveraged to derive novel performance metrics, which assess how teams use triangular positioning and how players tie up defenders during attacks. The outcome of N = 128,187 attacking sequences from 306 elite men's football matches is analysed using linear mixed-effects models to validate the proposed performance metrics. Results show that attacking success is characterized by player positioning which promotes forming of large triangles especially in ball proximity, whereas the overall number of triangles is of no relevance. Furthermore, players tie up more defenders and thus create free teammates more often during successful attacks. The results demonstrate that a new perspective on space is helpful to better quantify and understand the effect of space management and player positioning on attacking performance in football.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142468484","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}

Current literature suggests that RSH promotes metabolic modifications in muscle cells, especially driven by reactive oxygen species production, HIF-1α stabilization, and changes in metabolism. Training with BFR promotes metabolite accumulation in working muscles due to limited blood flow, however, cellular mechanisms affected by BFR during RST are less explored. Data highlight that RSH improves repeated sprint ability (RSA) in several sport disciplines (e.g. rugby, tennis, soccer, cross-country skiing). However, recent studies showed that addition of hypoxia or BFR during RST did not promote supplementary benefits on aerobic performance, force-velocity power profile, and <math><mrow><mover><mi>V</mi><mo>˙</mo></mover></mrow><mrow><msub><mrow><mrow><mi>O</mi></mrow></mrow><mrow><mrow><mn>2</mn></mrow></mrow></msub></mrow><mi>max</mi></math>.

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.

Comparing Inertial Measurement Units (IMUs) worn at five body locations (feet, shorts for thighs and pelvis, waist strap, and thorax in a standard GPS vest) with a force plate as a reference, we enlisted 19 amateur football players who performed a series of 10 maximal 30 m sprints (initiated every minute). Maximal jumps were executed immediately before and after each sprint, with the latter jumps recorded on a force plate integrated into the field. Bland Altman's bias (-0.49 cm) and limits of agreement (1.01 cm) were minimal for the feet IMUs. The thorax IMU had the highest bias (-6.35 cm), but the limits of agreement (2.73 cm) were similar to the other locations. Repeated measures correlations (rmcorr) between force plate and IMUs were excellent for the feet (rmcorr = 0.98) and good for the thorax (rmcorr = 0.86) and other locations except for the waist strap. In the fatigued state, within-session coefficients of variation ranged from 4.0% (pelvis in shorts) to 6.5% (waist strap).
