文摘

The bouncing ball model is applied for the analysis of dynamic effects of cadence. Energy loss due to ground-foot collision and impact intensity are estimated. Based on the model, higher cadence imply lower energetic costs and lower risk of injury. Video-captured kinematic data of 121 amateur runners validated the model. Statistics for step length, cadence, and walk-to-run transition speed are provided.
