SQ training was found to significantly improve vertical jump height (VJH) but greater than the HT. Neither SQ nor HT training had a significant impact on horizontal jump distance (HJD), short sprint time (SST), short sprint performance (SSP) or change of direction (COD) performance. In 12 to 16 sessions subgroup, SQ training significantly improved VJH, showing a medium ES. However, in other subgroups, neither SQ nor HT exercises produced significant improvements in HJD, SSP, SST, or COD performance. Subgroup analyses corroborated these findings. Squat exercises are more effective in developing VJH, while alternatively, no conclusive preference can be made between the exercises for enhancing HJD, SSP, and SST markers. Neither exercise had a discernible impact on COD performance.

Nine professional female cricketers (19.9 ± 2.8 years, 166.6 ± 4.8 cm, 68.7 ± 8.6 kg) performed 40 swings across four shot types (Cut, Drive, Pull, Slog-Sweep). Bat speed from a bat-mounted sensor was compared to optical motion capture (MoCap). Bat speed differed between shot types and ranged from 52.8 to 87.9 km/h. Device accuracy was determined by Bland-Altman bias and precision. The Drive shot had the smallest bias (-1.0 km/h; 1.4%), followed by the Slog-Sweep (2.0 km/h; 2.7%), Pull (2.0 km/h; 2.8%) then Cut shot, (2.5 km/h; 3.9%). The Cut shot had the greatest precision (2.7 km/h; 4.1%), followed by Pull (3.4 km/h; 4.7%), Slog-Sweep (4.0 km/h; 5.3%) and Drive (4.4 km/h; 6.3%). Kendall's tau analysis showed that proportional errors increased with higher bat speeds for all shots except Pull, (p < 0.05). The evidence supports use of the sensor for bat speed among female cricket players for all shots between speeds of 52.8-87.9 km/h.

This study investigates neuromechanical differences in single-leg jumps for maximum height and distance regarding propulsion and landing phases to identify joint- and muscle-specific deficits. Nineteen healthy women performed both jump types, with assessments including 3D kinematics, ground reaction forces, and electromyography (EMG). Joint kinematics and torques were calculated using OpenSim, and muscle synergies derived from EMG data using Non-Negative Matrix Factorization guided by Variability Accounted For (VAF) metrics. Statistical parametric mapping compared the centre of mass displacement, angular trajectories, joint moments, and neural commands between jump types. Maximal height jumps require greater hip joint effort and emphasise knee mechanics and pelvic misalignments in the frontal plane. During landing, height jumps impose higher demands on eccentric knee extension and pelvis list, whereas distance jumps necessitate increased lumbar extension torques. The reduced knee extension torque and increased knee, trunk, and hip flexion angles in distance jumps may protect the knee. Landing from height jumps promotes anterior pelvic tilt in the sagittal plane. The analysis shows that two muscle synergies reconstruct propulsion EMGs, while landing requires three, indicating increased complexity. These findings highlight the need for customised assessments targeting specific neuromuscular and biomechanical aspects of lower-limb function.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-17"},"PeriodicalIF":2.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145114771","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}

This study aims to identify short-track speed skating performance factors and quantify their impacts on athletes' performances. Twenty-nine short-track speed skaters (16 males and 13 females), with two different skill levels (National Elite and Junior Elite athletes), participated in this study. Movella IMU Link suits and Python scripts were employed to record and analyse one on-ice high-speed trial per athlete, focusing on lower body kinematics. From an initial pool of 535 tested factors, Pearson's product moment correlations and stepwise multiple linear regression identified seven significantly associated with lap time, with notable differences between sex and skill levels. Results revealed that inter-foot spacing and pelvic height, which are actionable by athletes, could each contribute to a gain of up to 0.51 seconds per lap if improved by 10 cm. For an average lap on a 500 m race, this means a 5.2%-time improvement. This research enhances the understanding of short-track speed skating performances by identifying factors that can improve lap times, offering practical implications for coaching strategies and athlete training programs.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-14"},"PeriodicalIF":2.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145114787","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}

It was hypothesised that training would significantly affect the magnitude and temporal structure of stride-to-stride variability during running. Twelve competitive adolescent runners (age: 16.3 ± 0.81) performed two 8-minute all-out running tests on a 400-m track, once at the start of the off-season (R1) and again after 6 weeks of structured training (R2). The study measured stride variability using the coefficient of variation (CV), monofractal analysis (DFA-α), and multifractal spectrum metrics (W and WAsym). No significant differences in CV and DFA-α between the two tests, suggesting stable magnitude and temporal structure of stride-to-stride variability in terms of monofractality. However, significant changes were observed in the multifractal spectrum, with a reduction in W and a shift in WAsym towards more symmetrical values after training. These results indicate that multifractal dynamics are a more sensitive metric to evaluate the effects of training on stride-to-stride variations in adolescent runners. The reduction of both W and WAsym leads to the assumption that alterations in neuromuscular control and adaptability in adolescent runners occurred due to training. Future research should further explore the utility of multifractal metrics in monitoring training progress and optimising performance in young athletes.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-17"},"PeriodicalIF":2.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145076458","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}

Current research is limited and inconclusive regarding the influence that transitioning between surfaces has on impact forces. Adult runners (n = 18) ran outdoors over a 50 m pathway that was half concrete and half grass at a self-selected speed. We recorded tibial acceleration from inertial measurements units and calculated resultant tibial acceleration for each step. We performed a three-way repeated measures ANOVA with Cohen's d effect sizes to compare resultant tibial acceleration among surface type (concrete, grass), transition step (preparation, response), and period (transition, steady state). We observed no significant interactions among surface type, transition step, and period for resultant tibial acceleration. We observed no significant main effect for transition step but observed that resultant tibial acceleration was significantly greater on concrete than grass and when transitioning compared to steady state, with small effect sizes. The increase in tibial acceleration during the transition period likely occurs across multiple steps when preparing or responding to a new surface. Runners that are concerned about experiencing higher tibial accelerations may want to consider running on softer surfaces and limiting the number of surface transitions during a training session.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-10"},"PeriodicalIF":2.0,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030704","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}

Split times (5-, 10-, and 15-m), stroke count, stroke rate, stroke length, and stroke phase distances (glide, pull, push, recovery) during acceleration and speed maintenance periods over the 15-m were measured. Regression analyses determined multiple spatiotemporal variables that strongly contributed to faster split times at all distances, including a sex interaction effect (r2 = 0.749, 0.791, and 0.794 respectively). For all surfers, push distance during acceleration and pull distance during speed maintenance were indicative of faster split times. For male surfers, the pull distance during the full sprint-paddle effort was indicative of faster split times. No variables were indicative of faster times for female surfers. This indicated that the development of a technique which promotes longer propulsive distances (i.e. pull and push distance) and an additional investigation of the female surfer should be encouraged to further afford optimal sprint-paddling success in both sexes.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-17"},"PeriodicalIF":2.0,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144976559","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}
