| Aims: Success in sports activities performance depends on many factors, including nutritional status of athletes therefor the aim of this study was to evaluate the effect of 4 weeks of glutamine supplementation on factors related to physical fitness in young wrestling. Methods: In this experimental study, 16 teenage wrestlers (18.85±1.6 in age range) participated and were randomly divided into two control (n=8) and experimental (n=8) groups. Both groups participated in their normal exercises, then the experimental group received glutamine supplement and the control group received placebo (maltodextrin) during 4 weeks. Before and after the research protocol, indicators related to physical fitness (strength, maximum oxygen consumption and speed) were evaluated. In the following, the obtained information was evaluated using independent t-test and significance level of p≤0.05 and Spss statistical software. Results: The findings showed that the strength of the lower and upper body muscles (p=0.04), as well as the maximum aerobic power (p=0.001) of the wrestlers in the experimental group was significantly higher than the control group. However, there was no significant difference (p=0.4) in the speed of the two groups. Conclusion: It seems that the consumption of glutamine amino acid supplement has an effect on the performance of physical activities and improves performance of strength and maximum oxygen consumption. | ||
