This study examined the impact of a short-time coordination program conducted during recess periods on improving agility in elementary school students. The subjects consisted of 60 third grade students, who were randomly assigned to an experimental group (n = 29) and a control group (n = 31). The experimental group completed a coordination program intended to improve agility during 20-minute recesses, two to three times a week for five weeks, whereas the control group participated in usual activities such as mini soccer games and tag games during the recess. Repetitive side steps, an indicator of agility, were measured for both groups at the beginning and end of the intervention period. While the test scores indicated no difference between the two groups in the pretest, the posttest indicated a significant difference in the test scores in favor of the experimental group, t (59) = 2.90 and p less than 0.005. The results indicated that the short-time coordination program can be effective in improving agility in elementary school students. (Contains 2 figures.)
