An Investigation Into Peak Limb Compliance In College Sprinters, Lilian Sahibdeen

Anthropology

During running, the limb acts as a mechanical spring where it compresses and recoils to release elastic potential energy with each ground contact. Maintaining maximal running speed is particularly important during sprinting. Individuals with stiffer limb springs are more efficient because of this. Limb stiffness can be calculated using Hooke’s law (k=F/ ΔL), where k is the spring constant, F is the peak ground reaction force, and ΔL is the change in hip height between the initiation of limb contact and the middle stance phase. Many factors contribute to limb stiffness and this study examines how stiffness variers with contact …
