VM/VL-ratio from athletes with and without chronic knee pain in hall, sand 1 and sand 2.xlsx

This table presents the integrated EMG of the M. vastus medialis and M. vastus lateralis and the M. vastus medialis/lateralis-ratio. Performed jumps included a Countermovement Jump and a spike jump. They were performed indoors (hall) and on two sand types. The first sand was subjectively judged by trainers and players as harder than sand 2.

本表格展示了股内侧肌（M. vastus medialis）、股外侧肌（M. vastus lateralis）的积分肌电图（integrated EMG），以及股内侧肌与股外侧肌的比值。本次测试包含的跳跃动作包括反向跳跃（Countermovement Jump）与爆发跳跃（spike jump）。所有测试均在室内场馆以及两种沙地环境中完成：第一种沙地经教练员与运动员主观评定，其硬度高于第二种沙地。
