The purpose of the research is to analyze the effects of plyometric training upon speed and power to junior high basketball players. Methods: The subjects of the experiment were twenty-one male junior high school basketball players (the average age 14.91 ± .32 years, height 163.60 ± 8.83 cm, weight 54.17 ± 13.77 kg). The subjects were divided into the experimental group (10 persons) and the control group (11 persons.) by counter-balanced order. The control group received ordinary training while the experimental group received plyometric training twice a week for twelve weeks. The training was based on the motion of plyometric traning in theory and in practice. And they got the training load by progress training. All the subjets filled in subjets with parents consent forms and health status surveys, and had a pretest and a posttest of speed and power. The tests included 30-meter sprints, standing long jumps, vertical jumps, and Burke anaerobic exercise. The data was analyzed by two-way mixed designed ANOVA to compare the differences between the two groups before and after the training. The level of α was set at .05. Results: After the plyometric training for twelve weeks, the ability of vertical jumps of the experimental group increased (p＜.05), and was better than the control group obviously in the posttest. The ability of long stand jumps of the two groups improved remarkably (p＜.05), but there were no abvious differences between the two groups in the posttest. The abilities of 30-meter sprints and Burke anaerobic exercise, there were no abvious differences between the two groups in the pretest and the posttest. Conclusion: Plyometric training for twelve weeks designed for the research could increase the acceleration of junior high basketball players efficiently, but there was no improvement in speed.
