A return to gymnastics framework, consisting of seven skill progression pathways, was developed. Twelve gymnasts were instrumented with mouthpiece sensors and performed two trials of each skill, if able. Sensors recorded data at 100 Hz and skill segments were extracted using time-synchronised video. Peak resultant linear (PLA) and rotational acceleration (PRA), rotational velocity change index (ΔRV) and peak resultant rotational velocity (PRV) of 1 Hz low pass filtered data were computed from skills. A mixed effects model evaluated differences in kinematic metrics across skills within pathways while adjusting for random effects of the participant. Stepwise increases in kinematic metrics occurred along backward and forward tumbling (floor) pathways but did not occur in other pathways. For instance, gymnasts experienced greater PLA and PRV during clear hip and back hip circle compared to giant. Moreover, skills performed early along respective pathways (e.g, Yurchenko timer (to back), Tsukahara timer (to back), handstand forward roll) were among the skills with the greatest PRA and ΔRV. Head kinematics associated with skill performance should be considered when developing return to gymnastics protocols.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-21"},"PeriodicalIF":2.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143711901","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 examines the impact of skill level, sex, and defender conditions on joint kinematics during unanticipated cutting in soccer players. Kinematic data were captured using a three-dimensional motion capture system for 14 competitive and 14 recreational players performing unanticipated sidesteps (45 ± 10 degrees) under three conditions: no obstacle (NO), static-defender obstacle (SO) and dynamic-defender obstacle (DO). Principal component (PC) analysis and hierarchical linear models examined joint kinematics against sex, skill and defender conditions. For the first component of PC, skill effects revealed greater ankle dorsiflexion angles throughout cutting in competitive players (p = 0.01) than recreational players. DO trials showed lower hip flexion (p = 0.001) and ankle dorsiflexion angles (p = 0.01) than NO. SO trials showed greater hip adduction (p < 0.001) and knee abduction angles (p = 0.04), but lower ankle dorsiflexion angles (p < 0.001) than NO. For PC2, SO trials showed greater hip flexion excursions (p = 0.005) than NO. No sex effects were found. Clearance (participant's distance to the defender) was examined using a three-way analysis of covariance. Greater distances were found in DO by 0.59 m than SO. Differences in cutting patterns highlight potential adaptations to varying defender pressures, providing insights for coaching and prevention programmes.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-18"},"PeriodicalIF":2.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143701865","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}

A convolutional neural network was trained on data from 7 inertial measuring units (feet, shanks, thighs, sacrum) and a pair of pressure insoles. We assessed performance over continuous time windows (CONT) and during stance phases (PHSS) by intraclass-correlation (ICC), normalised root mean squared error (nRMSE), and statistical parametric mapping. The agreement levels in the sagittal plane were good to excellent (ICC: 0.84-0.98), with low errors (nRMSE: 0.05-0.11). However, accuracy was lower for non-sagittal estimations (frontal ICC: 0.19-0.90, nRMSE: 0.08-0.23; transverse ICC: 0.72-0.94, nRMSE: 0.07-0.17). Accuracy decreased across all planes during PHSS.

We compared stiffness and spatiotemporal parameters between runners with different experience levels, including a group with no previous running experience. Healthy physically active participants (22.1 ± 3.6y) were divided into three groups, according to experience: experienced (running >1-year, 14-48 km/week; n = 23, 9F), novice (running <1-year, 5-21 km/week; n = 15, 4F) and non-runners (no running for the past 5 years; n = 17, 7F). Three-dimensional motion capture and force plates measured gait mechanics during overground running at 3.35 m·s-1. Knee, ankle and three-dimensional leg stiffness, contact time, flight time and step length were compared between groups using independent-measures ANCOVA (covariate = sex). No biomechanical variable was significantly different between the groups (leg: p = 0.652, Hedges' g = 0.09-0.17; ankle: p = 0.439, g = 0.07-0.19; knee: p = 0.153, g = 0.13-0.29; contact time: p = 0.592, g = 0.06-0.24; flight time: p = 0.513, g = 0.03-0.40; step length: p = 0.107, g = 0.26-0.61).

This study aimed to clarify the association of muscle fascicle length and antagonist muscle flexibility on muscle power output and velocity variables. Fascicle length and muscle thickness, pennation angle of vastus lateralis, knee flexor stiffness, and range of motion (ROM) were measured in American football players. Moreover, knee extension torque measurements were taken at five angular velocities (60 deg·s-1 - 300 deg·s-1), and theoretical maximum power (Pmax), maximum force (F0), and maximum angular velocity (V0) were calculated. Pearson's product-moment or Spearman's rank correlation coefficients were calculated for each variable. ROM showed a significant moderate positive correlation with Pmax. This suggests that the flexibility of antagonist muscles may influence the power output of agonist muscles. However, although muscle thickness showed a moderate correlation with F0, V0 did not significantly correlate with any of the variables. This finding suggests that other factors, such as rapid recruitment of motor units and muscle fibre composition, may play a more substantial role in torque at very high angular velocities than muscle morphology and mechanical properties.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-12"},"PeriodicalIF":2.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587805","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}

Fourteen athletes performed both forward running and sidestepping tasks. Head-trunk coordination and range of motion were assessed during the flight and stance phases in the transverse and sagittal planes. The sidestepping task resulted in greater in-phase head-trunk coordination during stance in the transverse plane (p < .001, ES = -1.71) and in reduced anti-phase coordination between head and trunk in the sagittal plane (p < .001, ES = 1.52). Statistical non-parametric mapping revealed that during sidestepping the sagittal plane coupling angle shifted away from anti-phase earlier during midstance. The sidestepping task resulted in greater transverse and sagittal plane head and trunk range of motion and greater vertical trunk centre of mass displacement. Sidestepping modified the intrinsic coordination dynamics that are present during forward running, with greater transverse plane head contributions and reductions in compensatory sagittal plane head motion, which may occur during the transition from weight acceptance to propulsion during the stance phase.

To verify the effect of the spin rate on speed decay by drag, the translational speed was measured at 0.15 s after passing the baseline (23 m/s); the balls with topspin ≥110 rps, close to participants' average (117 ± 29 rps) were 1.4 m/s faster than those with topspin ≤80 rps. The horizontal ball speed changed in the range of -3.1 to 2.6 m/s owing to table bounce.

The relationship between spin rate and travel time was non-linear with boundaries at 80 and 110 rps.

International-level compound archers executed 72 shots each in a competition-like environment. During both the aiming and shooting phases, bow displacement and tremor index were measured with a motion capture system, while postural sway indices, such as centre of pressure (COP) displacement and speed, were derived using a force platform. Two-dimensional arrow impact coordinates on the target were transformed into an accuracy index, calculated as the Euclidean distance from the target centre. In the aiming phase, smaller bow displacement and tremor, along with reduced COP displacement and speed, were associated with higher accuracy. This suggests that stable posture and bow orientation during aiming enhance shooting outcomes in compound archery. In the shooting phase after the release, bow and postural sway exhibited no differences depending on the shooting accuracy but correlated with the spatial distribution of arrow impacts. This result, combined with the reduced bow tremor in high-accuracy shots, suggests that strategies involving moderate, smooth, and consistent movement after release are more crucial for enhancing shooting accuracy in compound archery rather than simply minimising or restricting motion.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-14"},"PeriodicalIF":2.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494505","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}
