Abstract :
Inroduction & Objective:High intensity exercise and eccentric contraction due to micro injury and this injures have negative effect on athletics performance. This study aimed at investigation of BCAAs consumption effects on wrestlers` depth jumping performance in plyometric training.Methodsand material22 volunteer male wrestlers (age 21.54±3.52, weight 66.18±3.76, height 168.36±2.41, and BMI 23.34±1.97) were selected, using purposeful sampling, and randomly divided into two groups of Placebo and Amino acid. During the training period, both groups had breakfast at 7:00 a.m and two hours later, performed depth jumping in 6 consecutive sets until fatigue, with 5 minutes of resting between each sets and received their supplementation in a blindfold manner before and after depth jumping exercise. Group one consumed 45 mg/kgBW of each Amino acid (Valine, leucine and Isoleucine) in the form of 4ml/kgBW solution per each kg of body weight. The Placebo group also used a solution with the same volume. Paird and independent t-test was used to investigate the change rate in performance and the significance level of inter and intra group was considered to be (P≤0.05).ResultsThe results showed that the performance of group Amino acid was significantly higher than the Placebo group (P≤0.05). In intra-group comparison, the performance of both groups had significant increase after three months of plyometric training (P≤0.05).ConclusionAccording to the results, since the exercise type, duration and intensity for both groups were the same, most probably the consumption of BCAAs supplementation had positive effects on jumping performances during plyometric training.
