Abstract
The main goal of the study was to analyze differences in support phase during first and second ground contact after semi-low position start. Dynamometry as a method was used to determine the contact forces in both strides independently.
Key parameters desribing the support phase were calculated from data from Kistler 3D force plate. Wide range of contact times wase achieved by tested individuals as well as force and speed production.
Different startegies were identified in first two strides for each individual. If a braking phase occurs during these strides, it leads to increase of support time and also to a decrease of average acceleration.
