摘要

有人提出足弓有助于提高跑步的代谢效率。计算肌肉骨骼模拟稳态后脚和非后脚撞击在一系列跗骨中关节（即足弓）的刚度表明，随着刚度的增加，后脚撞击跑步的代谢运输成本降低了约5%，但在非后脚撞击跑步中增加了约11%。在两种跑步足撞击条件下，随着跗骨中关节刚度的增加，对其进行的机械功的大小遵循类似的减少模式，这表明除了足部能量储存和返回之外的机制是导致代谢成本变化的原因。

Midtarsal joint stiffness alters the metabolic cost of simulated running via mechanisms other than changes in foot energy storage and return.

The foot's arch has been proposed to aid in metabolically efficient running. Computational musculoskeletal simulations of steady state rearfoot and non-rearfoot strike running across a range of midtarsal joint (i.e. foot arch) stiffnesses indicated that with increasing stiffness the metabolic cost of transport decreased by ∼5% in rearfoot strike running but increased by ∼11% in non-rearfoot strike running. The magnitude of mechanical work performed about the midtarsal joint as its stiffness increased followed a similar decreasing pattern in both running foot strike conditions, suggesting that mechanisms beyond foot energy storage and return were responsible for the altering metabolic cost.
