We examined the agreement between 6 HJC estimation methods; compared hip, thigh, and knee angles; and explored HJC location and thigh angle associations. Pelvis markers were used to estimate HJC location via 6 popular methods using Harrington's method as the reference standard. 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. Stepwise regression showed that anterior-posterior, medial-lateral, and anterior-posterior HJC coordinate differences best explained sagittal (R2 range = .95-.99, P < .001), frontal (R2 range = .83-.99, P < .001), and transverse (R2 range = .54-.72, P < .001) thigh angle differences, respectively. Different HJC methods caused several large sagittal but more minor frontal and transverse plane differences. We urge caution when using different HJC methods.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-9"},"PeriodicalIF":1.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144188495","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}

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. The results of this study suggest that MTP orientation changes have no implications for the length-determined contributions of the flexor hallucis longus and flexor digitorum longus to the ankle plantar flexion moment.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-4"},"PeriodicalIF":1.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144188496","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}

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. Understanding differences in head kinematics between WAG and MAG can help guide sport- and sex-specific injury prevention strategies.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-14"},"PeriodicalIF":1.1,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144182512","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}

Nine experienced, right-footed, male soccer players instep kicked a stationary ball in 3 different angled directions, 15°, 45°, and 75° relative to the run-up direction, and a motion capture system with a force plate recorded the kicking data. Kinematic and kinetic variables of the support leg, associated with pelvic rotation about the vertical axis, were compared among the kicking conditions. The pelvic rotation significantly increased in response to larger kicking angles, and it coincided with increase of the support leg hip joint and foot segment rotation about the vertical axis. The joint torque at the support leg hip joint significantly increased with the kicking angles. Additionally, the interaction torque due to the ground reaction force was the primary factor driving foot segment rotation relative to the force plate in angled kicking conditions, whereas no remarkable action of the free moment existed. Instep kicks toward angled directions involve a mechanism that increases the pelvic rotation about the support leg's hip joint and foot segment, which differs from the mechanism involved in straight kicks.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-10"},"PeriodicalIF":1.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144052365","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}

Vision and knowledge of landing heights may influence how athletes anticipate and respond to landings. This study examined the effects of the removal of visual input and knowledge of landing heights on knee biomechanics associated with ACL injury risk. Thirty-three recreational athletes performed single-leg landings from 3 different heights (11, 22, and 33 cm) under 3 conditions: with both vision and knowledge, with knowledge but without vision, and without both. The no vision and no knowledge condition resulted in an intermediate strategy that produced similar landing mechanics for 22 cm but significantly different kinematics and kinetics for 11 and 33 cm. Slower knee flexion angular velocities, increased peak vertical ground reaction forces, and greater knee internal rotation and abduction angles suggested increased ACL loading for 33 cm. Landing patterns with knowledge but without vision closely matched those with both. Removing both vision and knowledge significantly altered landing mechanics, emphasizing the need to train athletes to accurately anticipate initial contact of landings and adopt safe landing strategies under restricted visual and uncertain or perturbed conditions.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-13"},"PeriodicalIF":1.1,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144058229","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}

Given that altered loading of the surgical knee has been the most proposed mechanism for early knee OA post-ACLR, understanding how modulating walking speed may modify knee joint loading is essential for developing strategies to reduce the risk of knee OA in ACLR patients. The purpose of this study was to determine how modulation of walking speed affects knee joint loading during overground walking post-ACLR. Lower extremity kinematics and kinetics were recorded during overground walking at a self-selected, slower, and faster speed from 16 patients with unilateral ACLR. The results showed that ACLR patients demonstrated lesser peak knee flexion and adduction moments of the surgical knees when walking at slower speeds. However, modulating walking speed did not alter between-limb knee loading asymmetry. The ACLR limbs had lower peak knee flexion moments than the uninjured limbs across all 3 walking speeds. Although interventions that increase walking speed may deter the onset of knee OA by elevating the mechanical stimulation at the surgical knee, additional gait training strategies may be needed to restore the between-limb loading symmetry in ACLR patients.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"1-9"},"PeriodicalIF":1.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144053243","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}

An inertial motion capture system and a force plate were used to collect running biomechanics data for training the ANN. Kinematic data from optical motion capture systems, sourced from publicly available databases, were used to evaluate the prediction performance and accuracy of the ANN. The linear and angular momentum theorems were applied to compute ground reaction forces and joint moments in the physics-based approach. The main finding indicates that the recurrent ANN tends to outperform the physics-based approach significantly (P < .05) at similar and higher running velocities for which the ANN was trained, specifically in the anteroposterior, vertical, and mediolateral ground reaction forces, as well as for the knee and ankle flexion moments, and hip abduction and rotation moments.
