Abstract
Introduction: Strenuous exercise training cause the imbalance between oxidants and antioxidants in the body and can lead to complications. The purpose of this study was to compare the effect of strength and plyometric training on serum levels of malondialdehyde and total antioxidant capacity in active youth volleyball players.
Methodology: For this purpose, 30 volleyball youths participating in different teams of Bojnourd in the age group of 16 to 18 years old were selected through convenience sampling and randomly divided into 3 equal groups, resistance training, plyometric training and control. The training groups performed their protocols in addition to the 60 minute usual volleyball training, 3 sessions per week for 8 weeks. Strength training program included bench press, leg press, squat, barbell curl, barbell shoulder press and standing calf raise for 30 minutes with 60 to 80% 1RM. Plyometric training program included, front box jump, forward and backward jump, sides jump, up and down box jump, and medicine ball throw. The control group performed their usual volleyball exercises within 8 weeks. Blood sampling was done 24 hours before and 48 hours after training program. Data were analyzed using one way ANOVA and post-hoc Bonferroni tests (P<0.05).
Results: The results showed that 8 weeks strength training reduced the serum level of MDA (P=0.47) and increased serum TAC level (P=0.015) in youth volleyball players. However, plyometric training had no effect on serum levels of these variables (P>0.05).
Discussion: The results of this study indicate that regular and continuous strength training in comparison with plyometric training, can reduce oxidative stress and its complications by reducing MDA and increasing TAC in youth volleyball players.
