摘要: Abstract A simple model is developed to find vertical force profiles and stance durations that minimize either limb mechanical work or peak power demands during bipedal locomotion. The predicts minimization achieved with a symmetrical profile, consistent previous models observations of adult humans, data for 487 participants (predominantly 11–18 years old) required walk at range speeds Science Fair. Work also the discrete walk-run transition, familiar humans. In contrast, modeled are minimized an early skew in ground reaction increases speed, decrease steadily speed across minimizing transition speed. therefore continuous gait quantitatively measurements younger children (1.1–4.7 years) locomote but free select their own gaits.
