The Spring Mass Model
- AConsequently, this passive recoil significantly reduces the metabolic cost of muscular work over long distances.
- BIn this conceptual framework, the body's centre of mass is treated as a single point supported by a compliant leg spring.
- CAs the runner lands, this leg spring compresses to store mechanical energy within the tendons and ligaments.
- DHuman running can be mathematically simplified as a bouncing spring-mass system.
- EMuch of that stored elastic strain energy is subsequently recoiled to propel the body forward during toe-off.
