The foot has been studied in walking, running and jogging using high speed cinema photography in the laboratory for gait analysis in the Shriner's Hospital for Crippled Children, San Francisco. During running, as well as in walking, the extrinsic toe flexors restrain progression of the tibia. The extrinsic extensors accelerate the tibia over the fixed foot. The intrinsic toe muscles function from mid-stance to lift-off when the subject runs on his toes. In sprinting, the intrinsics are active throughout the weight-bearing phase.
在旧金山施赖纳 crippled 儿童医院的实验室中，运用高速电影摄影技术对步行、跑步和慢跑时的足部进行了研究，以分析步态。在跑步以及步行过程中，外在趾屈肌会抑制胫骨的前进。外在伸肌会使胫骨在固定的足部上方加速。当受试者用脚尖跑步时，内在趾肌从中期支撑阶段到离地阶段发挥作用。在短跑时，内在趾肌在整个负重阶段都处于活跃状态。
