the Main Mechanical Parameter Studied When Using the Spring-Mass Model in Treadmill Running

Writer:realleaderfitnessDate:2017-2-2 09:01:07
The main mechanical parameter studied when using the spring-mass model in treadmill running is the stiffness of the leg spring, defined as the ratio of the maximal force in the spring to the maximum leg compression at the middle of the stance phase.Moreover, although it does not correspond to any physical spring,the term vertical stiffness is used to describe the vertical motion of the center of mass (CM) during contact,and is defined as the ratio of the maximal force to the vertical displacement of the CM as it reaches its lowest point, i.e., the middle of the stance phase. Maximal ground reaction force and CM displacement measurements during running are needed to measure these parameters requiring dynamometers such as overground or treadmill-mounted force platforms, or even video motion-analysis.Such equipment is costly and not practical for field measurements.
