Weight loss in many sports that involve weight classes is very important; the weight can have a major role in the success of athletes. The aim of this investigation was examining the effect of rapid and gradual weight loss protocols on lactic acid in trained wrestlers. Twenty-two trained wrestlers [age 20–25 years] volunteered to research and randomly assigned into two groups: rapid and gradual weight loss group. Group 1 applied rapid weight loss method in 48-h and group 2 used twelve days gradual method. All subjects asked for a reduction of about 4 percent of their weight. Before and after weight loss intervention, lactic acid was measured. The results demonstrated that the amount of increase in lactic acid in the rapid weight loss group was more than gradual group after tests. Comparison of these two weight loss protocols exhibited that in compare with rapid weight loss, the gradual weight-loss method leads to a lesser decrease in wrestlers\\\\\\\' metabolic changes.
