Effect of Short-term Glutamine Supplementation on Muscle Damage Indices and Pain after Extroverted resistance activity in Sedentary Young Men

Delayed muscle contusion may occur as a result of damage to the involved muscle structure after performing resistance exercise or extrovert exercises. The aim of this study was to investigate the effect of glutamine supplementation on muscle injury indices and pain after extroverted resistance activity in inactive young men.

This quasi-experimental study was performed with repeated measurements in 2017-18 among all inactive male students of Mohaghegh Ardabili University who had not participated in regular sports activities during the three years leading up to the study. 20 samples were randomly divided into two supplement nodes (n = 10) (daily consumption of 0.1 g glutamine per kg of body weight) and placebo (n = 10). The training protocol included an extrovert activity phase. Plasma levels of creatine kinase, lactate dehydrogenase, perceived pain were measured before exercise, 24 and 48 hours after extraversion resistance activity. Shapiro-Wilk statistical methods, repeated measures analysis of variance and independent t-test at the significance level of p <0.05 were used to analyze the data.

The results of the present study showed that the amount of perceived pain in the placebo group was significantly increased compared to the supplement group in the 24 hours after exercise (p = 0.008) and 48 hours after exercise (p = 0.046). Also, 24 hours after extraversion, the levels of creatine kinase and lactate dehydrogenase increased in both groups, but no significant difference was observed between the two groups (p> 0.05).

Glutamine supplementation appears to be helpful in preventing the negative effects of delayed muscle soreness in the recovery period after physical activity, which is often accompanied by extroverted contractions.
