Fourteen adults (eight females, six males) completed three sprints, with mean activation for the deltoid, trapezius, biceps, triceps, latissimus dorsi, erector spinae, external oblique and rectus abdominus measured for each 10 m phase of the sprints, along with velocity, acceleration, net horizontal force (FH) and the ratio of FH to net sagittal ground reaction force (RF%). Overall, activation of the deltoid, trapezius, biceps and triceps declined during the later phases of the spint, while latissimus dorsi, erector spinae and external oblique activation increased after 0-10 m. From 10 to 20 m, activation of the latissimus dorsi and erector spinae were positively correlated with velocity, acceleration, FH and RF% (p-values 0.003-0.04). Erector spinae activity was also positively correlated with velocity (p = 0.01) and acceleration (p = 0.03) from 20 to 30 m. It seems that activation of the shoulder and arm musculature declines as runners near peak velocity, while trunk musculature activation increases. Erector spinae and latissimus dorsi activity may also be critical during the transition from peak acceleration to peak velocity while sprinting.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-10"},"PeriodicalIF":2.0,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148431330","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}

Two trials per athlete were analysed from 0 to 10 m using high-speed video (240 fps) to obtain 2D spatiotemporal kinematics. Our first hypothesis, using group mean data, was that males would accelerate faster and have longer step lengths, but that there would be no significant male vs. female differences for the temporal variables. Our second hypothesis, focusing on individual data, was that although there would be similar times to 10 m within male and female groups, individual combinations of contact time, flight time, step rate, and step length would be used. Both hypotheses were confirmed. The results of this study indicated that from a group mean perspective, males and females displayed different acceleration performance (~7% difference, p < 0.001) but similar temporal variables (|Δ| ≤0.003 s difference, all p > 0.369).

Extensive research and commentary exist on the measurement of technique, including the wide range of technology available and the many diverse forms, structures and domains of the variables quantified. The analytical methods used to understand the interactions between these measures of technique and performance outcomes have also received considerable attention. However, the process of selecting the performance outcome measure rarely receives explicit focus, even though it can bias the conclusions reached for a variety of reasons. We therefore present a seven-step procedural framework to guide the selection or development of appropriate performance outcome measures for sports biomechanics investigations. Three published examples from our previous work, supported by other hypothetical scenarios, illustrate how the framework can be applied from different perspectives and across different sports. The framework will better enable biomechanists to identify, evaluate, and mitigate conceptual and measurement-related biases in established and novel performance measures. Ultimately, it supports the selection of outcome measures that best suit the given question, enhancing the validity and impact of biomechanical investigations designed to support sports performance.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-15"},"PeriodicalIF":2.0,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148377695","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 rearfoot-strike soldiers performed running tests under three load conditions (0, 10, and 20 kg) while wearing either minimalist shoes or combat boots. The coordinates of the body landmarks and ground reaction force data were simultaneously collected using the infrared high-speed motion capture system and force plates. The musculoskeletal model was established to calculate AT biomechanical parameters. Results showed that AT force impulse and stance duration increased with higher load magnitudes. Load carriage increased AT force during the midstance phase but decreased it during the early stance phase. Compared with combat boots, running in minimalist shoes decreased AT force during the terminal stance phase and shortened stance duration but increased AT force during the early stance phase. However, no main effect of footwear on AT force impulse was found. Additionally, no interaction effect between footwear and load carriage magnitude was observed for any biomechanical parameter. These findings suggest that minimalist shoes provide limited acute benefits in reducing cumulative AT loading and therefore are not recommended for soldiers during load carriage.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-23"},"PeriodicalIF":2.0,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148377703","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 investigated the effects of wrist height relative to the shoulder at FC on the joint moments and pitching kinematics in high school and collegiate pitchers using a motion capture system. Peak elbow varus and shoulder internal rotation moments, along with upper extremity, pelvis, and upper torso kinematics, were compared among pitchers with the wrist positioned below, at, or above the shoulder at FC. Compared with pitchers whose wrist remained below the shoulder, those with the wrist above the shoulder demonstrated greater elbow varus and shoulder internal rotation moments, greater shoulder external rotation and upper torso rotation throughout most of the arm-cocking phase, a shorter arm-cocking phase, and earlier timing of key pitching events. Delaying the throwing arm motion during the stride by having a wrist below the shoulder at FC may help elongate the arm-cocking phase and minimize joint moments. Wrist height at lead foot contact may provide a simple and practical method for identifying pitchers who may be experiencing elevated joint loading. The findings also support the concept that pitching mechanics at lead foot contact influence kinematics throughout the subsequent phases of the pitching motion.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-16"},"PeriodicalIF":2.0,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148377658","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}

Concerns exist that full assistance may reduce active muscle engagement due to passive contributions. Thirteen male athletes from various sports performed 30-m sprints under three conditions: unassisted, partially assisted, and fully assisted, using a motorised towing device. Surface electromyography recorded activity of five lower limb muscles (rectus femoris, vastus lateralis, semitendinosus, biceps femoris, and gluteus maximus), while spatiotemporal parameters were measured over the final 10 m using Optojump. Sprint times were significantly improved in both assisted conditions compared to unassisted sprints (partial: -3.4%, full: -2.8%; p < 0.01), primarily due to increased stride length (p < 0.001), longer flight time, and shorter contact time (p < 0.05 for both), while stride frequency remained unchanged. Contrary to hypothesis, EMG analyses revealed no statistically significant differences in muscle activity between conditions, despite improved performance and the potential contribution of passive propulsion. Large effect sizes (d > 0.8) were briefly observed, in a muscle-dependent manner, at discrete points of the gait cycle. These findings suggest that assisted sprinting enhances performance without reducing neuromuscular demands, although the results should be interpreted in light of the athletes' inexperience with assisted running.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-14"},"PeriodicalIF":2.0,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148377684","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}

All analyses focused on the contact phase of the second hand. Elbow and Wrist joint flexion/extension (EF/E-WF/E) and rotation (EROT-WROT) couplings were assessed using modified vector coding to determine coupling angle (CA) and variability (CAV). Elbow joint adduction/abduction moments (Melbow) and joint power (JPelbow) were calculated using inverse dynamics. Joint kinetics and CA were overlaid on the same plots to visualise how kinetic patterns corresponded with coordination dynamics. Results showed decreased Melbow using the T-shape technique (p < 0.001) with EROT-WROT in-phase, while Reverse and Parallel techniques exhibited anti-phase with increased Melbow (p < 0.001) and lower CAV using Reverse technique. Furthermore, EF/E-WF/E coupling revealed technique-specific control strategies; notably, the T-shape technique exhibited a different transition from anti-phase to in-phase motion, indicating a potentially more effective transfer from JPelbow absorption to generation.

Postural stabilisation during landing was assessed using an inertial sensor placed on the lumbar spine, from which data was used to determine the dynamic stability index and time to stabilisation. Muscle activity was assessed using surface electromyography in six lower limb muscles. The results showed that the muscle activity of the lower limbs differs according to the difficulty and direction of the motor task preceding the landing. The activity of the knee flexors and plantar flexors during landing after forward and backward motor tasks proved to be more beneficial for improving postural stabilisation.
