However, its generation mechanism in the triple loop (T-LP) remain underexplored. The aim of this study was to address this gap by analysing the segmental contributions to angular momentum generation. Ten female skaters performed the T-LP while undergoing three-dimensional motion analysis. Although the AM increased first due to the contribution of the upper limbs during the glide phase, the AM of the lower limbs increased more significantly during the transition phase, with a particularly notable contribution from the non-supporting leg. A slight reduction in AM was observed during the Pivot phase just before take-off. These findings suggest that, unlike off-ice jumps where AM is typically generated by the arms and trunk, T-LP on ice involves a different strategy. Furthermore, no significant correlation was found between AM at take-off and key jump performance parameter such as jump height, rotational velocity, or flight time. This suggests that optimal jump execution requires coordinated integration of other biomechanical factors, including take-off mechanics and aerial posture control. These insights may aid in refining training strategies and optimising jump mechanics in figure skating.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"827-840"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145543627","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}

However, how such exposure influences the coordination dynamics underlying head stability control, and thus visual perception, is not well understood. The purpose of this study was to assess whether contact sport participation affects coordination variability and stability during locomotion as a function of different levels of visual task constraints. Ice hockey (contact) and baseball (noncontact) athletes completed treadmill walking tasks with varying levels of visual task constraints. Head and trunk local dynamic stability and whole-body coordination variability were assessed at preferred and fast speeds with and without a dynamic visual acuity task. While no group differences in dynamic visual acuity were present, contact athletes displayed reduced vertical head local dynamic stability compared to non-contact athletes while walking at a fast speed without the visual task. Contact athletes also displayed lower whole-body coordination variability compared to noncontact athletes. These findings suggest that contact sport participation may lead to changes in head stability control and lower levels of coordination variability, suggestive of reductions in movement flexibility and adaptability.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"872-893"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145901494","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}

Eleven participants (age: 25.9 ± 3.1 years, height: 180.4 ± 5.4 cm, body mass: 87.0 ± 7.9 kg) performed eight repetitions to failure with a narrow, medium and wide grip width. Statistical parametric mapping was used to analyse kinematics and kinetics during the entire concentric phase of the last repetition. The main findings revealed that narrower grips increased both load lifted, and shoulder, and elbow range of motion. Moreover, grip width influenced horizontal barbell forces throughout 100% of the lift, and joint kinetics during the initial 64% of the lift. Wider grips increased lateral barbell forces and reduced elbow net joint moments (NJMs), while narrower grips increased medial forces and reduced shoulder NJMs. These findings suggest that grip width modulates joint kinematics, NJMs and lateral barbell forces during the shoulder press.

Before and after 8 weeks of training, the drop jump (DJ) and isometric mid-thigh pull (IMTP) tests were performed to evaluate force-time measures. The optimal drop height was determined as the height that provided the highest reactive strength index (RSI).

Lastly, differentiation factors were identified for each group. It was observed that a low initial velocity during Turn 1 was common in both men's and women's categories.

Fifteen young, 15 middle-aged and 15 older adults participated in this study and were invited to perform the following conditions: single-task running; motor dual-task, involving grasping a cup of water while running and cognitive dual-task, consisting of solving subtraction problems while running. Dependent variables included stride length, width, duration and velocity, as well as knee and ankle joint angles. Older adults exhibited shorter stride length and duration and reduced knee and ankle range of motion compared with younger and middle-aged groups, who did not differ from each other. Both motor and cognitive dual-tasking significantly interfered with most kinematic variables, particularly reducing stride length and joint motion, and increasing stride width. Motor dual-tasking tended to induce greater disruption than cognitive dual-tasking. These results indicate that older runners present distinct kinematic patterns compared to younger and middle-aged adults, and dual-tasking adversely affects running performance. The observed alterations suggest reduced adaptability of running in older adults when simultaneous tasks are introduced.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-22"},"PeriodicalIF":2.0,"publicationDate":"2026-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147965023","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}

Twelve national level I male table tennis athletes participated in a within-subject design, performing both foot support patterns. Compared with ASP, FSP showed significantly lower peak hip power generation (10.38 ± 1.42 W/kg), lower ankle power generation and absorption, with reduced ankle rates of change. In addition, the relative contribution of ankle power generation (1.25 ± 1.60%) decreased, leading to a higher combined contribution of the hip (93.62 ± 3.76%) and ankle (4.96 ± 4.46%) joints. The peak time of ankle power absorption was significantly delayed. By contrast, the relative contributions of hip and knee power generation were higher in FSP than in ASP.

Four international coaches and two international judges assessed animations of the optimal techniques and of an elite athlete's technique, providing insights into the acceptability of the optimal techniques. For the most complex acrobatics, coaches found all optimal techniques more efficient for aerial twist creation. However, they perceived them as less safe, less realistic, similarly aesthetic, and similarly appropriate for visual information intake compared with the athlete's technique. Judges assigned fewer deductions to the simulated techniques than to the athlete's performance.
