The purpose of this study was to compare the differences of shooting period for junior archers at different target distances. Sixteen subjects were voluntarily participated in this study. In order to obtain athlete performances, in the present study, we used high speed camera (Mega Speed MS10K CCD B/W, 120 Hz) to collect data. Paired t-test was adopted to compare the significant differences (α=.05) at different target distances and Pearson correlation was used to exam the relationship among the drawing period (DP), lunching period (LP), shooting period (SP), and shooting ratio (SR). The results were presented as follows: (1) DP and LP of shorter target distance for the junior high school athletes were related to the scores significantly. DP, LP and SR of longer target distance for the junior high school athletes were related to the scores significantly. The DP, LP, SP and SR of two target distances weren, t related to the scores significantly for elementary school athletes. (2) Only DP were related negatively to LP significantly when the target distance was short for elementary school athletes. (p＜.05) (3) As the target distance increased, the scores would be decreased. The athletes spent more time in DP. Only the SR of the shorter target distance was larger than that of the longer target distance for elementary school athletes. It was concluded that the shooting period (SP) should be divided into two periods. As the target distance increased, the athletes of elementary school should spend more time in drawing period to enhance the steady of shooting.
