Study Assess Vertical and Leg Stiffness During Treadmill and Overground Running

Writer:realleaderfitnessDate:2017-2-6 09:51:05
Validity of the proposed sine-wave method: The aim of this study was to provide a calculation method based on a few simple parameters allowing vertical and leg stiffness to be assessed during treadmill running and overground running without a force platform. The low bias obtained between force platform and model values,and the high determination coefficients,demonstrate the validity of this calculation method during both treadmill running and overground running. Furthermore, the validity of this method was tested for a wide range of velocities with runners of different ability levels,from nonspecialists to highly trained middle-distance runners, all giving acceptable results. This may allow us to use the proposed method during submaximal to maximal velocity running, with either nonspecialists or elite athletes, in field conditions. It should be also noted that the mechanical parameter input to the model also showed acceptable reference-model bias.
