FORCE ANALYSIS OF THE UNDERWATER STATIONARY RUNNIG

Abstract

It aimed to analyze the vertical component of the ground reaction force in the underwater stationary running. The sample was composed by 6 subjects divided in two groups (Male Group and Female Group). The underwater stationary running was performed in two immersion levels: in the hip level and in the xiphoid process level. An underwater force plate was used. For data analysis descriptive statistics was used. The mean values of vertical GRF were 2,08BW for the MG and 1,69BW for the FG in the hip level; 1,15BW for the MG and 1,12BW for the FG in the xiphoid process level. The results showed the vertical component of the GRF is affected by the immersion level and by the frequency of the activity. Both factors should be considered by professionals who work with therapeutic or physical conditioning programs using the underwater stationary running.
