In order to address gaps in the literature, this study assessed the reproducibility (i.e., difference between and within sessions) of joint and muscle forces using wearable sensors during stationary cycling. Seventeen male cyclists performed two sessions on a cycle ergometer cycling at a combination of three power outputs (1.5, 2.5 and 3.5 W/kg) and three pedalling cadences (60, 80 and 100 rpm) in two sessions (2-7 days apart). The first trial from each session was repeated at the end of the session for assessment of within-session reproducibility. Three-dimensional (3D) full-body motion and 3D bilateral pedal forces were collected using an inertial motion tracking system and a pair of instrumented pedals, respectively. Joint angles, muscle forces and knee joint forces were computed using OpenSim. Poor to excellent agreement (ICCs = 0.31-0.99) was observed and differences were trivial to small and non-significant between trials within-session. Poor to excellent agreement (ICCs = 0.05-0.97) was observed and differences were trivial to large between sessions. Variability can be attributed to changes in muscle recruitment strategies (within and between-sessions) and to repositioning of sensors (between-sessions).

:为了解决文献中的空白,本研究评估了在固定骑行过程中使用可穿戴式传感器对关节和肌肉力的可重复性(即,各节之间和各节之间的差异)。 17名男性骑自行车的人在自行车测功机上进行了两次训练,分别以三个功率输出(1.5、2.5和3.5W / kg)和三个踩踏节奏(60、80和100 rpm)进行了两次训练(相隔2-7天) 。在会议结束时重复每届会议的第一次试验,以评估会议期间的可重复性。分别使用惯性运动跟踪系统和一对仪表踏板来收集三维(3D)全身运动和3D双向踏板力。使用OpenSim计算关节角度,肌肉力和膝关节力。观察到差于极好的一致性(ICC = 0.31-0.99),并且在会议期间的两次试验之间的差异很小至不重要。观察到差于极好的一致性(ICC = 0.05-0.97),并且会话之间的差异很小到很大。差异可归因于肌肉补充策略的改变(在疗程中和疗程之间)和传感器的重新放置(疗程之间)。
