The purpose of this study is to estimate the ground reaction force in running to use two-dimensional kinetic skeleton model also to examine the validity of their approach with changing running rate. The subjects are healthy 2 people in university. The subjects run 5times; subjectively increasing 5 running rate. The results are as follows. 1) Lowering the cut-off frequency, waveform of the ground reaction force is smooth and the maximum value is decreasing. 2) The vertical waveform of the ground reaction force shows a high cross-correlation coefficient under condition of low sampling rate, but the forward waveform of the ground reaction force shows a high cross-correlation coefficient under condition of high sampling rate. 3) Regardless of the running rate, the vertical waveform of the ground reaction force is smaller. 4) Characteristics of the ground reaction force are different by the subject.
