Unilateral surface EMG data were collected from 16 muscle groups in the trunk and lower limbs during both SLH30 and SLH100 in 10 healthy males. Nonnegative matrix factorization was used to extract muscle synergies. The number of muscle synergies in SLH100 was significantly higher than in SLH30 (P = .0078, effect size = 1.28), with median values of 4.0 (3.0-5.0) for SLH30 and 5.0 (4.0-6.0) for SLH100. We identified 4 shared muscle synergies between SLH30 and SLH100, signifying a foundational neuromuscular control strategy. In addition, muscle synergies specific to SLH100 demonstrated the involvement of abdominal muscles and hip and ankle extensor muscles, highlighting their contributions to achieving longer hopping distances. Interventions aimed at enhancing SLH performance for return to sport may benefit from incorporating exercises targeting these synergy patterns. However, it should be noted that SLH100 synergies primarily involved nonknee muscles, warranting caution when using SLH as an indicator of knee function as improvements in hop distance may not directly reflect knee-specific recovery.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-9"},"PeriodicalIF":1.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Musculoskeletal model estimation of this variable is time-consuming, expensive, requires trained researchers, and is restricted to lab settings. We aimed to simplify the measurement of the medial knee joint contact force during walking and running using custom instrumented insoles and deep learning methods. Motion capture, force plate, and insoles instrumented with triaxial piezoresistive force sensors recorded data while 9 young healthy female individuals walked and ran at varying speeds. Two task-specific convolutional neural networks were developed for walking and running using piezoresistive force sensors as inputs during the stance phase. Results showed that both models were able to estimate total medial joint contact force with strong correlation coefficients (r > .98) and moderate mean absolute error (<0.36 body weight). These methods show the possibility of collecting medial knee joint contact force during walking and running in a clinical setting. Future research with this framework can be used to provide biofeedback to reduce medial knee joint contact force in high-risk knee osteoarthritis groups in clinical settings and daily life.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-7"},"PeriodicalIF":1.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute changes to these properties in response to submaximal running have been noted but not yet tested in maximal effort bouts. This study assessed the acute effects of high-intensity interval running on PF thickness and stiffness in healthy adults. Sixteen participants completed 5 maximal effort 400-m sprints with a 1:1 work-to-rest ratio, followed by additional maximal effort trials until fatigue. Thickness and stiffness at the calcaneal origin were measured prerun, postrun, and 30 minutes postrun via ultrasonography and shear wave elastography, respectively. PF thickness and stiffness did not differ between right and left foot (P > .05) and between males and females (P = .067). Thickness and stiffness decreased postrun (0.43 mm, P < .001; 1.54 m·s-1, P < .001) and increased 30 minutes postrun (0.28 mm, P < .002; 1.0 m·s-1, P < .001). No significant difference was found between prerun and 30 minutes postrun thickness (P = .134), but prerun stiffness was higher than 30 minutes postrun (P = .031). These findings indicate that although high-intensity interval running altered both PF thickness and stiffness, 30 minutes of rest allowed some level of recovery in the noninjured PF tissue.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-5"},"PeriodicalIF":1.1,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144334515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The symposium was thematically framed around the evolution of integrative, multidisciplinary research in the biomechanical study of human activity and behavior. With the foundations of biomechanical research being laid in controlled laboratory settings, advancements in wearable sensor technology have allowed investigators to capture increasingly sophisticated real-world activity and behavior and physiological data (eg, physical activity, sleep, and heart rate) that may be linked to biomechanical processes (eg, gait biomechanics), which are integral to optimizing health and wellness in the context of human performance, physical activity, exercise, and sport. Wearable sensors enable the collection of unprecedented amounts of meaningful data that can be used to make previously unknown associations among behavior, biomechanics, physiology, and health outcomes that may lead to new and useful scientific insights. These unique discoveries are propelled by multidisciplinary and integrative collaborations in technology, biomechanics, physiology, artificial intelligence, and data science.

HJC limits of agreement analysis and inferential angle comparisons during standing revealed that Bell's (HJC bias range = 0-11 mm, hip angle difference range = -0.2° to 0.1°) and Vaughan's (HJC bias range = -5 to 41 mm, hip angle difference range = -0.5° to -5.3°) methods were most and least like Harrington's but varied by dimension.

This effect may arise as 2 ankle plantar flexors, the flexor hallucis longus and the flexor digitorum longus, cross the MTP joint. It was the purpose of this study to determine the influence of the MTP joint on maximum voluntary isometric plantar flexor moments. Maximum isometric ankle plantar flexion moments were measured for 8 subjects with the MTP joint in either neutral or fully dorsiflexed position while the angles of the knee joint (90° flexion or fully extended) and ankle joint (4 angles) were systematically varied, giving 16 sets of joint configurations. There was no significant effect of the MTP joint angle on the maximum plantar flexion moment (P = .41), but both the ankle and knee joint angles had a significant effect (P < .001). During the stance phase of human gait, the MTP joint angle changes.

Twelve female and 8 male artistic gymnasts (ages 11-18) wore mouthpieces with triaxial accelerometers and gyroscopes to perform a series of gymnastics skills from 5 common skill progression pathways: backward tumbling (floor), bar elements, forward tumbling, and vault-specific skills (Tsukahara and Yurchenko). Data were recorded at 100 Hz for 10-minute intervals and time-synchronized with video recordings. Peak linear acceleration (PLA), peak rotational acceleration (PRA), resultant change in rotational velocity during the maximum rotational acceleration (ΔRV), and peak rotational velocity (PRV) were compared using mixed-effects models. WAG experienced greater PRV during noncontact skills (eg, giant and clear hip). MAG experienced, on average, 1.7 times greater PRA during skills with significantly different PRA between MAG and WAG. MAG tended to have higher kinematic values for PLA, PRA, and ΔRV during contact phases compared with WAG. It is important to understand head kinematics in nonconcussive situations, as postconcussed gymnasts may have lower tolerance to head acceleration events during recovery.
