Study About a Simple Method for Measuring Stiffness During Treadmill Running

Writer:realleaderfitnessDate:2017-1-23 09:36:23

We compared this method to force-platform-derived stiffness measurements for treadmill dynamometer and overground running conditions, at velocities ranging from 3.33 m·s–1 to maximal treadmill running velocity in both recreational and highly trained runners. Stiffness values calculated with the proposed method ranged from 0.67% to 6.93% less than the force platform method, and thus were judged to be acceptable. Furthermore, significant linear regressions close to the identity line were obtained between force platform and sine-wave model values of stiffness. Given the limits inherent in the use of the spring-mass model, it was concluded that this sine-wave method in treadmill running allows leg and stiffness estimates in running on the basis of a few mechanical parameters, and could be useful in further field measurements.
