Abstract

This research analyzed the peak impulsive force, maximum velocity and a spot of fist's maximum velocity comparing stop-jirugi and push-jirugi. 7 males volunteered for this experiment. peak impulsive force was measured by PS2142 force platform[10], and maximum velocity of fist was measured by PS2103A motion sensor[12]. All of data was collected in the data studio and t-test was applied using SAS 9.1 package. The following conclusions were drawn. First, stop-jirugi's peak impulsive force was greater (P<.01) than that of push-jirugi. Second, push-jirugi's maximum velocity of fist was greater (P<.01) than that of stop-jirugi. Third, stop-jirugi's maximum velocity of fist was occurred on 69.14% of arm's length and that of push-jirugi was occurred on 75.66%. This maximum velocity spot was statistically significant difference(p<.001).
