The aim of this study was the evaluation of step types on one-two straight in boxing. For this study, 8 male boxers of K University were participated in the experiment. The two phases that composed of three events on one-two straight motion were analyzed on vertical force of GRF. The seven infrared cameras (Qualisys MCU-240) were used to acquire raw data, and then the Matlab6.5 was used to process data. The sampling rates of a camera were 240Hz and the coordinate data were filtered using a moving average method filtering with 25frames after calculation. The conclusions were as follows: First, correlation between the height of right heel and linear velocity of left ankle was not statistically significant. Second, there were two types on one-two straight in Boxing. Third, time finishing vertical displacement of type A had longer than type B. And the GRF of type A decreases after 0.125 seconds but the GRF of type B decreases at the same time with beginning. Fourth, as for GRF with respect to types, step patterns of type B wad smoother than those of type A because GRF rate in relation time of type A larger than type B. In the future, it is desirable that we will study neuromuscular variables and coordination between lower and upper limbs in boxing.
