چکیده مقاله :
Background: The present study was conducted with the aim of determining the effect of plyometric exercises with arginine supplementation on some physical fitness factors of beach soccer players for the purpose of injury prevention. Method: Based on the research entry criteria, 20 beach soccer players were selected and were randomly assigned to two groups of plyometric exercises (n=10) and plyometrics with arginine supplement (n=10). Then, age, height, weight, and physical fitness factors including aerobic and anaerobic capacity, muscle strength and endurance, and fat percentage of subjects were evaluated. The first training group received plyometric exercises with arginine supplement. In the second group, plyometric exercises were applied along with placebo. After 8 weeks of training, physical fitness factors were re-evaluated. The correlated T test was used to determine the intra-group changes and the ANCOVA test was used to compare between the groups. The obtained results were analyzed using SPSS version 26 software. Results: The findings showed that both plyometric training programs with and without arginine supplementation had a significant effect on improving aerobic power (P=0.002, P=0.001), anaerobic power (P≥0.01), muscle strength. (P=0.001), muscle endurance (P=0.004) and fat percentage (P=0.001). Also, the results of comparing the effects of two training programs show that there is a significant difference between the two training programs in the variables of aerobic power (P=0.01), anaerobic power (P≥0.05) and fat percentage (P=0.02). Conclusions: According to the results and previous studies, using two types of plyometric exercises, with and without using Arginine supplementation especially with arginine supplementation could be useful to prevent sports related injuries specially ankle and knee sprains and groin strain which are prevalent among soccer players of all types specially beach soccer players. It is explained by different mechanisms including affecting aerobic and anaerobic powers, muscle strength and endurance, and body fat.
