摘要: Abstract An analysis of the energy components human gait in sagittal plane has been made employing kinematic and anthropometric data. The television data source does not encumber natural is sufficiently complete so that drastic simplifying assumptions are necessary for analysis. instantaneous kinetic (translational rotational) potential calculated shank, thigh torso. following conclusions can be drawn: 1. (i) torso acts as a conservative system with about half its change interchanging. 2. (ii) conserves ca. 1 3 change. 3. (iii) shank largest total changes, but virtually no exchange between potential. 4. (iv) In all rotational component, 2 Iω , ignored. 5. (v) stride-to-stride changes body were less than 4% average energy.
