Spring-Mass Model Is a Widely Used Concept in Studies on Treadmill Running and Bouncing Mechanics

Writer:realleaderfitnessDate:2017-1-23 09:33:07

The spring-mass model, representing a runner as a point mass supported by a single linear leg spring, has been a widely used concept in studies on treadmill running and bouncing mechanics. However, the measurement of leg and vertical stiffness in treadmill running has previously required force platforms and high-speed kinematic measurement systems that are costly and difficult to handle in field conditions. We propose a new “sine-wave” method for measuring stiffness during running. Based on the modeling of the force-time curve by a sine function, this method allows leg and vertical stiffness to be estimated from just a few simple mechanical parameters in treadmill running: body mass, forward velocity, leg length, flight time, and contact time.
