There is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. Due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. Therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of injury. To examine the effects of an aquatic-plyometric training (APT) program on vertical jump height compared with land based plyometric training. The subjects were 120 amateur boy Taekwondow players of 10 to 14 year  old in  Oshnavieh City. Twenty six boy Taekwondow players (12/19 ± 1/80 yr, 41/5 ± 1 kg, and 156/49 ± 4 cm) were randomly divided to aquatic plyometric(n=13) and control groups(n=13).All groups participated in pretest vertical jump. Experimental groups performed six weeks of plyometric exercise twice weekly and 45-55 minutes every session, in addition to traditional Taekwondow training either in water pool or at gym. In addition, after 4 weeks of practice, exercises to overload the 4 was  increased to 10 duplicate. In 3 groups vertical jump height) first session, after 4 week and after 6 weeks of training .but control groups performed only normal exercise and also of total groups  in post-test had modeled of vertical jump and muscle soreness. ( =0.05). The statical analysis of variance analysis were used for repetition and size to describe the raw data and to test the hypotheses from descriptive and inferential statistics largely dependent and independent T and anova were used for analysis. ( =0.05). The results displayed significant increases in vertical jump height after six weeks of training in APT group.The aquatic plyometric training that can cause to improve athletes vertical Jump ( =0.05)
