The aim of the study was to quantify the activity as recorded by electromyography during ergometer cycling in eleven different muscles of the lower extremity. Eleven healthy subjects rode in twelve different ways at different work-load, pedalling rate, saddle height and pedal foot position. Vastus medialis and lateralis, gastrocnemius medialis and lateralis and the soleus muscle were the most activated muscles. Changes in muscle activity during different calibrations were studied in eight of the eleven muscles. An increase in work-load significantly increased the mean maximum activity in all the eight muscles investigated. An increase of the pedalling rate increased the activity in the gluteus maximus, gluteus medius, vastus medialis, medial hamstring, gastrocnemius medialis and soleus muscles. An increase of the saddle height increased the muscle activity in the gluteus medius, medial hamstring and gastrocnemius medialis muscles. Use of a posterior pedal foot position increased the activity in the gluteus medius and rectus femoris muscles, and decreased the activity in the soleus muscle.
该研究的目的是量化在测力计骑行过程中通过肌电图记录的下肢11块不同肌肉的活动情况。11名健康受试者以12种不同方式在不同工作负荷、蹬踏频率、鞍座高度和踏板足部位置下骑行。股内侧肌和股外侧肌、腓肠肌内侧头和外侧头以及比目鱼肌是激活程度最高的肌肉。在11块肌肉中的8块中研究了不同校准过程中肌肉活动的变化。工作负荷的增加显著提高了所研究的所有8块肌肉的平均最大活动量。蹬踏频率的增加提高了臀大肌、臀中肌、股内侧肌、半腱肌内侧头、腓肠肌内侧头和比目鱼肌的活动量。鞍座高度的增加提高了臀中肌、半腱肌内侧头和腓肠肌内侧头的肌肉活动量。采用踏板足部后置位置增加了臀中肌和股直肌的活动量，并降低了比目鱼肌的活动量。
