Eighty-one male university-level football players were equipped with helmet accelerometers to capture peak linear acceleration (PLA), impact frequency, and helmet impact location. Impacts with PLA ≥ 60 g were included in this analysis. Video footage from 15 games over three seasons was analysed to characterise aspects of play including play type, position, closing distance, tackling versus blocking, and impact. Impacts occurring at the left outside boundary of the field resulted in significantly higher linear accelerations. Impacts with a closing distance of ≥10 yards resulted in higher PLA compared to <10 yards and occurred most frequently in run plays. Helmet-to-body impacts generated significantly higher PLA compared to helmet-to-helmet, though helmet-to-helmet occurred more often. Players being tackled sustained significantly higher PLAs than those blocking. The results of this work suggest that the left outside boundary is an area of importance for spotters looking to identify high-risk impacts. Further, rules regarding offensive backfield running starts could be adjusted to decrease the risk of impact after a larger closing distance.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-21"},"PeriodicalIF":2.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796902","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}

The second objective of this study was to clarify the relationship between the approach-run velocity obtained by different three methods and the maximal height of the athlete's centre of mass (COM) during the clearance. 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}

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. The proposed approach yields similar or better accuracy compared to previous work while requiring less preprocessing. It provides a viable method for wearable-based assessment of running kinetics in near real-time.

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).

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}

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}

No differences in supraspinatus MT, stiffness and shoulder ROM were found. Our study found that Brazilian professional padel players have asymmetrical shoulder ER/IR peak torques ratio.
