行走所需的大部分机械功来自穿过踝关节的肌肉和肌腱。通过在每一步中储存和释放跟腱中的弹性能量，人类极大地提高了踝关节工作的效率，远远超出了膝关节和髋关节的工作效率。人类在行走过程中在踝关节产生机械功，其效率比孤立的肌肉效率高出两到六倍。
A large portion of the mechanical work required for walking comes from muscles and tendons crossing the ankle joint. By storing and releasing elastic energy in the Achilles tendon during each step, humans greatly enhance the efficiency of ankle joint work far beyond what is possible for work performed at the knee and hip joints. Humans produce mechanical work at the ankle joint during walking with an efficiency two to six times greater than isolated muscle efficiency.
