Reducing the amount of fatigue and its subsequent effect on form is valuable for improving running performance. It is unknown what effects compressive clothing has on musculature; however, there have been claims that it may reduce fatigue. The aim of this study was to determine whether compressive tights or running shorts are more beneficial for improving performance when running to exhaustion. Eleven runners ran at their current five-kilometre race pace on a treadmill to voluntary exhaustion in a repeated measures design wearing both compression tights and running shorts while their biomechanics, heart rate and rate of perceived exertion were recorded. Fatigue effects showed a less extended knee angle (p = 0.03) and a smaller ankle dorsiflexion angle (p = 0.04) at initial contact, and increased loading rate (p = 0.02) and vertical impact peak (p = 0.05). Condition effects included a shorter stride length (p = 0.01), faster stride rate (p = 0.01), and decreased hip range of motion (p = 0.02) with compression tights. There was no significant difference in time to exhaustion between conditions (p = 0.88). Thus, the length of time to fatigue was unaffected by condition, however, the altered mechanics when running in compression tights may reduce potential injury.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-11"},"PeriodicalIF":2.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first case study, we present and use a novel metric, the velocity variation score, to maximise breaststroke technical performance for an athlete with Achondroplasia Dwarfism, by comparing their normal technique to two alternates, focused on 1) fast arm sculling and 2) high stroke rate (HSR). We observed lower velocity variation scores using the adapted breaststroke techniques (p < 0.001), the HSR technique had the lowest velocity variation score (p < 0.001). In the second case, we determine the optimal breathing strategy, breathing to the impaired or unimpaired side, for an athlete with a unilateral hand impairment performing freestyle swimming. Results showed that the forward velocity was significantly lower in the left-to-right stroke cycle transition and right (arm pull) when breathing to the impaired (left) side. To varying degrees, these cases demonstrate that wearable-based intra-stroke analyses can provide individualised technique recommendations that benefit competitive race peformance.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-14"},"PeriodicalIF":2.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five different filter settings (from 0_0 to 4_4) were used with the OJ to detect the contact event, based on the number of LEDs (from 1 to 5). No significant differences (p > 0.05) were found between the two devices in any of the stride variables when the 4_4 filter was implemented using the OJ. The agreement was good for contact time (CT) and flight time (FT) [r = 0.81-0.93; Typical error of the estimate (TEE%) = 3.2-7.5%], whereas for stride frequency (SF), stride length (SL) and stride time (ST) the agreement was almost perfect (r = 0.91-0.99; TEE% = 0.2-1.7%).

While loading in each individual plane of the knee can contribute to injury, combined loading seems to be the most likely mechanism. This study investigated if knee joint moments are related to the foot strike angle in pre-planned and unplanned handball-specific sidestep cuts performed by n = 51 female handball players. Canonical correlation analysis (CCA) with the foot strike angle at initial ground contact serving as the predictor variable was performed on the knee joint moment vector field (Mxyz). In both conditions, the foot strike angle was related to Mxyz. Subsequently, post-hoc tests were conducted using CCA for moment couples (Mxy, Mxz, Myz) and linear regression for individual moment components. Results revealed that traditional analyses focusing on individual planes only partially explain the observed relationships, particularly during the unplanned cutting condition. Given the time periods in which correlations exist, this study shows that manipulating the foot strike angle has the potential to reduce multi-plane knee loading associated with ACL injury, while limiting analyses to individual planes might underestimate the potential to mitigate ACL injury risk.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-11"},"PeriodicalIF":2.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144095498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten highly skilled and 10 less skilled judokas performed uchimata, with movement data recorded using a Mac3D motion analysis system (250 hz). The peak values of the body centre of mass velocity in the anterior-posterior and vertical directions were significantly greater in highly skilled judokas compared to their less skilled counterparts. Furthermore, the peak angular velocity of the hips, shoulders and arms, as well as the peak angular momentum of the technique recipient (uke), were significantly greater in highly skilled judokas than in less skilled ones. This suggests that judokas with advanced skills may execute throws more efficiently during throwing movements. Furthermore, a larger forward propulsion during the turning phase may be crucial in generating angular velocity in the hips, shoulders and arms during the throwing phase. Judo coaches should be aware of the accelerated body rotation during throwing that can be achieved by increasing the whole-body forward velocity. This insight can guide in enhancing the training protocol design when teaching uchimata and assist judokas in mastering the technique more efficiently.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-16"},"PeriodicalIF":2.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144047219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eighteen male athletes performed 96 pole-vaulting attempts in outdoor competitions. Bland-Altman plots indicated that only the peak approach-run velocity obtained by the body-only method had negligible bias, while other parameters obtained by body-only digitising and laser methods contained several errors. Since such bias could cause problems, using conventional digitising and laser methods requires careful handling. The association between maximal COM height during the clearance and peak approach-run velocity was extremely large for all three methods. In contrast, although the relationship between the maximal COM height and the decrease in approach-run velocity was large for both digitising methods, it was weakened for laser method. Consequently, based on the approach-run velocity parameters, different calculation methods for approach-run velocity parameters resulted in varying relationships with jumping performance.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-16"},"PeriodicalIF":2.0,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
