Abstract
Objective:This study aimed to evaluate the effect of different doses of glutamine after an exhaustive physical activity on LDH and Ck levels and pain index in Men footballers.
Methods: In a quasi-experimental study, 32 male athletes (age: 22.35 79 1.79 years) Were divided randomly into three groups receiving glutamine (dose 0.1, 0.3, and 0.6) and placebo equally (n =8) were located. Subjects consumed 0.1, 0.3, and 0.6 grams of glutamine and 10 grams of placebo dextrin in 500 ml of water, respectively, immediately after performing the Bruce exhaustion test. LDH, CK, and pain index were Measured before, one, 24, and 48 hours after the test. Data were analyzed using repeated measures analysis of variance at a significance level of P≥0.05.
Results: Significant decrease in LDH (0.6 dose), CK (0.3 and 0.6 dose) levels. And pain index was observed in all doses (p≥0.05). LDH, CK, and pain index levels increased significantly in all groups one hour after the test (p≥0.05). Decreased levels of LDH, CK, and pain index were Reported(48 hours after exercise, this decrease was 0.6 faster in the dose group than in other doses. There was also a significant difference between the groups in CK level and pain index 1 hour after activity with 24 hours and 48 hours after activity (p≥0.05).
Conclusions:It is Recommended that soccer athletes use glutamine at a dose of 0.6 mg to reduce the risk of muscle injury and pain following strenuous activity
