Introduction: The purpose of this study was determine the effect of upper body plyometric training on anaerobic power and record of 25 meters Chest swimming performance in 10 years old swimmer boys .Method: 16 swimmer boys, member of the provincial swimming team were chosen voluntarily (The mean age was 9.9 ± 0.7 years ، weight 45.9 ±9 kg , Height 149.8 ± 5 cm، BMI  is 19.20 ± 3 Kg / m 2  ) And divided into two groups of training (n=8) and control(n=8).  The training group performed upper body plyometric training 6 weeks, 3 sessions per week (18 sessions) and each session lasted 16 to 35 minutes. 25 meters backstroke swimming performance and hand writing t Anaerobic test function was evaluated before and after 6 weeks. To analyze the data, the covariance test and Bonferron’s post hoc test were used .Findings: The results showed six weeks of high plyometric training on the upper body of swimmers anaerobic performance Including Peak power increased Significantly (18%) but the average power increase (7%) was not significant (p <0.05). Also swimming performance at 25 meters increased significantly (1%) (p <0.05).Result: six weeks of plyometric training on anaerobic power of the upper body and the performance of swimmers backstroke Compared to the control group Improved significantly 18 % but the average of power with 7 % progress were not significant(p>0.05). Also, swimming performance in 10, 10-20 and 25 meters distance respectively have 8%, 6% and 1% growth in compare to control group that was significant(p <0.05). As well as in the number of hand shots, Plyometric training group although had growth in 10 meters (11%), 10-20 meters (7.5%) and in 25 meters distance (5.33%) but the significance of both training and plyometric groups were not observed(p>0.05).Conclusion: overall results indicate that six week plyometric and Anaerobic Power of upper body and performance of chest chalk swimmers swimming into control group improving significantly and and could be used as a complementary exercise method in young swimmers.
