The purpose of this study was to evaluate how floating toes affect baseball pitching motion. Fifteen young male baseball players pitched from a pitching mound after physical examination, including floating toes, determining if any toes are ...
Direct arm angle versus release-based proxies in Major League Baseball pitchers: a large-scale validation study [0.03%]
MLB投手直接臂角度与基于释放的代理：一项大规模验证研究
Morgan Dillon,Nicholas Frappa,Michael A Mastroianni et al.
Morgan Dillon et al.
Arm slot has been implicated in pitching biomechanics and injury risk, yet large-scale studies relied on indirect release-based proxies, yielding contradictory findings. With Statcast's Hawk-Eye system providing an anatomically defined meas...
Kinetics of the lower limb during the rotational movement of the body in osoto-gari: a comparison between black belt and white belt judokas [0.03%]
黑带与白带柔道运动员在大外刈投时身体旋转动作中下肢运动学的比较研究
Lingjun Liu,Tatsuya Deguchi,Mitsuhisa Shiokawa et al.
Lingjun Liu et al.
This study aimed to clarify how pivot leg kinetics influence body rotation during the osoto-gari throw by comparing black- and white-belt judokas. Twenty male judokas (10 black and 10 white belts) performed osoto-gari. Three-dimensional coo...

Gerwyn Hughes et al.
Research investigating landing biomechanics has used various tasks to ensure consistent/comparable conditions. This study examined repeatability of three landing tasks (suspension, step-off and vertical jump) and compared lower limb biomech...
Lower limb mechanics in kendo men and kote strikes: a within-subject comparison of joint-torque and ground-reaction-force temporal coordination and timing strategies [0.03%]
Kendo中的下肢力学：在关节扭矩和地面反作用力的时序协调和时机策略方面进行的一组内对比研究（面部护具攻击与小臂护具攻击）

Tsuyoshi Takeda,Daiki Koga,Takaaki Tsunokawa et al.
Tsuyoshi Takeda et al.
This study aimed to identify the optimal transition velocities between streamlined glide (SL), underwater dolphin kick (DK), and front crawl (FC) during high-speed swimming. Ten elite female swimmers performed front crawl and dolphin kick t...
The role of lower body kinematics in optimising trunk dynamics and ball speed during the field hockey drag-flick [0.03%]
曲棍球击球动作中下肢运动学对躯干动力学和击球速度优化的作用
B J Ladru,I Tak,B Kortekaas et al.
B J Ladru et al.
Timing and coordination of body kinematics are crucial for drag-flick performance in field hockey. This study aimed to clarify how coordination between the lower limbs and trunk contributes to effective energy transfer by (1) comparing lowe...
Effects of handheld dumbbell load on force-time characteristics during countermovement jumps with accentuated eccentric loading in youth athletes [0.03%]
