This study investigated the impact of training on stride-to-stride variations in adolescent runners. It was hypothesised that training would significantly affect the magnitude and temporal structure of stride-to-stride variability during ru...
The influence of transitioning between grass and concrete surfaces on resultant tibial accelerations while running [0.03%]
跑步时在草地和混凝土场地之间转换对胫骨加速度的影响
Nina Sebastian,Micah C Garcia,Kevin R Ford et al.
Nina Sebastian et al.
Running over 'softer' surfaces is thought to lower the magnitude of impact forces. Current research is limited and inconclusive regarding the influence that transitioning between surfaces has on impact forces. Adult runners (n = 18) ran out...
Differences in the rotation angles of the upper, middle, and lower thoracic spine, lumbar spine, and pelvis during front crawl swimming [0.03%]
不同水平仰泳时胸椎上、中、下段及腰椎和骨盆的旋转角度差异研究
Takato Ogata,Tomoya Takabayashi,Haruki Toma et al.
Takato Ogata et al.
Body roll during front crawl swimming refers to spinal rotation along the longitudinal axis. It is typically evaluated at the shoulders and pelvis; however, the middle and lower thoracic and lumbar spine are overlooked. Therefore, we aimed ...

Spatiotemporal kinematics represent a novel domain within surfboard sprint-paddling. Investigating the interplay between stroke characteristics and sprint-paddling speed can inform the development of effective training strategies for both f...
Between-session reliability and minimal detectable difference of peak tibial acceleration during running on an indoor track [0.03%]
室内田径跑道上跑步时胫骨加速度的跨 session可靠性和可检测最小差异
Zoe Y S Chan,Hannah Dimmick,Reed Ferber et al.
Zoe Y S Chan et al.
Peak tibial acceleration (PTA) is commonly used to assess impact loading during running, but the number of strides required for reliable between-session measurement in overground conditions, as well as the minimal detectable difference (MDD...
The impact of accumulated pitching counts on performance and lower body neuromuscular fatigue in baseball players: a simulated game analysis [0.03%]
棒球运动员累计投球数对表现和下肢神经肌肉疲劳的影响：模拟比赛分析
Hung-Chih Yeh,Chia-An Ho,Cheng-Hsun Hsieh et al.
Hung-Chih Yeh et al.
The study aimed to investigate the effects of accumulated pitching counts on lower body neuromuscular fatigue (NMF) and pitching velocity. Twelve first-level collegiate baseball pitchers completed seven simulated innings (a total of 105 pit...
Effects of on-plane wrist release style on morphological, temporal, and kinematic swing characteristic in golf drives performed by skilled male golfers [0.03%]
一种平面腕释放式挥杆对熟练男性高爾夫球手击球形态、时间及摆动特性的影响研究
Kai-Jen Cheng,Kanji Mori,Byungjoo Lee et al.
Kai-Jen Cheng et al.
A key motion in developing clubhead speed (CHS) during a golf swing is wrist cocking and uncocking on the swing plane. This study aimed to investigate how the morphological, temporal, and kinematic characteristics of drives performed by 84 ...
Drop vertical jump performance and asymmetries in young rhythmic gymnasts [0.03%]
年轻节奏体操运动员垂直跳跃表现及不对称性研究
Eleonora Passacantando,Stefano Marinelli,Stefano La Greca et al.
Eleonora Passacantando et al.
Rhythmic gymnastics (RG) is an Olympic discipline that emphasises repetitive unilateral movements that may lead to musculoskeletal asymmetries. The present study aimed to investigate the lower limb asymmetries during drop vertical jumps (DV...
Influence of using individualised ergonomic handles on upper limb kinematics and neuromuscular activity, perceived comfort and performance during scull rowing [0.03%]
