对20名受试者的腿部和足部6块肌肉同时进行肌电图检查，结果表明，只有重负荷才能激发肌肉活动。一只脚上100到200磅的负荷很容易由支撑足弓的被动结构（韧带和骨骼）承担。体重达到400磅时，肌肉确实开始发挥作用，但即使如此，许多肌肉仍然不活动。足弓的第一道防线是韧带。这些肌肉形成了一种动态储备，在过度负荷时会反射性地调用，包括步行中的起飞阶段。
Simultaneous electromyography of six muscles in the leg and foot in 20 subjects reveals that only heavy loading elicits muscle activity. Loads of 100 to 200 pounds on one foot are borne easily by passive structures (ligaments and bones) that support the arches. With 400 pounds, the muscles do come into play, but even then many remain inactive. The first line of defense of the arches is ligamentous. The muscles form a dynamic reserve, called upon reflexly by excessive loads, including the take-off phase in walking.
