Comparison of the Effects of 6 Weeks of Traditional and Wrestling-Technique-Based Circuit Training on the Blood Levels of Lactate, Lactate Dehydrogenase, Glucose, and Insulin in Young Male Wrestlers

Background: Nowadays, circular training has become more common than traditional training in wrestling. Objectives: This study aimed to compare the effects of 6 weeks of traditional and circular wrestling training on blood lactate, lactate dehydrogenase (LDH), glucose, and insulin concentrations in young male wrestlers. Methods: Twenty-seven young male wrestlers were randomly divided into 3 groups (ie, traditional wrestling training, circular wrestling training, and control groups) and performed interventions based on the group name for 6 weeks. Blood samples were taken from all subjects 48 hours before and 48 hours after the interventions and sent to a laboratory for analysis. Blood concentrations of lactate, LDH, glucose, and insulin were measured by enzyme-linked immunosorbent assay (ELISA). Data were analyzed using multivariate analysis of covariance (MANCOVA) and suitable post hoc test. Results: Traditional training significantly increased plasma lactate concentrations of wrestlers (P = 0.01) and had no significant effect on their serum LDH, insulin, and glucose concentrations (P > 0.05). Circular training significantly increased plasma lactate (P = 0.03) and serum insulin (P = 0.004) concentrations and had no significant effect on serum LDH and glucose concentrations (P > 0.05). Conclusions: These 2 types of training have a similar effect on the measured variables; however, it seems that circular training has a more significant effect on the measured variables than traditional training, which can probably be attributed to the use of more lactic energy resources and apparatus in circular training, which in turn can be used in preparation.
