Propulsive capacity - the maximum ability to generate forward propulsion during push-off in walking - is an important determinant of walking performance. Accordingly, an insufficient ankle push-off can limit physical activity and community ...
Inline aerodynamic drafting optimization in long-distance running: the effects of pacer body size on drag and performance [0.03%]
长跑中流线型空气动力学配速优化：配速员体型对阻力和表现的影响
Fabien Beaumont,Rodger Kram,Edson Soares da Silva et al.
Fabien Beaumont et al.
This study investigated the influence of pacer body size on the aerodynamic drag experienced by elite marathon runners. Using 3D numerical simulations, various drafting configurations were analyzed at a running speed of 21 km/h with 1.2 m s...

Effective weapon control in fencing requires precise coordination of forces across the fingers, yet the organization of digit-level grip forces during dynamic fencing actions remains largely unknown. We aimed to quantify finger-force distri...
From motion to deformation: a large-scale study of concussive versus non-concussive head acceleration events and brain strains in Canadian university football [0.03%]
从运动到变形：加拿大高校美式足球运动员震荡性与非震荡性脑震荡事件和脑应变的大规模研究
Jeffrey S Brooks,Wayne W Allison,Kewei Bian et al.
Jeffrey S Brooks et al.
Sport-related concussion arises from complex brain loading during head acceleration events (HAEs). However, tissue-level responses in Canadian university football remain poorly characterized. This study quantified head kinematics and finite...
Analysis of homeostatic biomechanical thresholds in a left ventricular model of growth and remodelling [0.03%]
生长重建左心室模型的稳态生物力学阈值分析
Debao Guan,Xinyang Ge,Qiaolan Wu et al.
Debao Guan et al.
Biomechanical models of myocardial growth and remodelling (G&R) are often modelled as responses to deviations from a preferred biomechanical homeostatic state, triggered by stretch or stress. Yet how these critical values of stretch and str...
Comparison of running power algorithms across different running speeds in 1,550 recreationally active adults [0.03%]
1550名业余活跃成人不同跑步速度下的功率算法对比研究
Gustavo Leporace,Thiago F Shida,Nicholas Metsavaht et al.
Gustavo Leporace et al.
Running mechanical power can be estimated using formulations that quantify different components of mechanical work, including external center-of-mass dynamics and internal segmental work. Several algorithms have been proposed to estimate ru...
Multi-joint synergies stabilize anteroposterior and vertical toe clearance during single-step ascent [0.03%]
多关节的协同作用在单步上阶过程中稳定前后和垂直方向上的脚尖通过间隙动作
Mateus Santos-Dias,Douglas V Russo-Junior,Paulo B de Freitas
Mateus Santos-Dias
Single-step ascent (SSA) requires precise control of foot trajectory, as insufficient or excessive toe clearance may increase tripping risk, compromise balance, or reduce movement efficiency. We expected that anteroposterior and vertical to...
Characterizing the effects of muscle weakness on margins of stability and joint mechanics during gait in persons with incomplete paraplegia due to spinal cord injury [0.03%]
脊髓损伤不完全性双瘫患者的步态稳定性和关节力学的肌肉无力对其影响的研究
Minh Tat Nhat Truong,Emelie Butler Forslund,Åke Seiger et al.
Minh Tat Nhat Truong et al.
Individuals with incomplete spinal cord injury (iSCI) exhibit diverse walking capabilities due to partial sensory and/or motor impairment below the injury level. This study examined how neuromuscular weakness patterns influence compensatory...
Mediolateral and anteroposterior balance control during Sit-to-Stand in individuals with transfemoral amputation [0.03%]
膝上截肢者在坐到站立过程中 mediolateral 和 anteroposterior 平衡控制的能力
