The purpose of this study was to examine the effect of plyometric training on power and agility in male basketball players of elementary school. 13 participants were divided in to a plyometric exercise group (n=6) and a control group (n=7). Plyometric training program was carried out under the condition of 3 days a week for 12 weeks. Power (sargent jump, 50m sprint, 4fun drop jump) and agility (SEMO run test, Zigzag run test) of all participants were measured before and after the experiment participation. All data were expressed as mean and standard deviation. Paired and independent t-test was performed to test the significant levels of differences within and between groups by using SPSS program. Significance was established at the α=.05. Consequently, sargent jump was significantly increased within plyometric exercise group and 50m sprint, 40cm drop jump, SEMO run test, Zigzag run test were significantly improved within plyometric exercise group, and plyometric exercise group also manifested significant differences in 50m sprint, 40cm drop jump, SEMO run test, Zigzag run test, compared with control group. In summary when considering the above results, plyometric training could improve the levels of power and agility in male basketball players of elementary school.
