Effect of Eight Weeks of Concurrent Training on Liver Enzymes, Lipid Profile, and Insulin Resistance ‎Among Overweight Male Children

Aims: The aim of this study was to investigate the effect of eight weeks of combined exercise training (aerobic-resistance) on liver enzymes, lipid profile, and insulin resistance among overweight boys. Method: Thirty-two healthy overweight boys voluntarily agreed to take part in the study following the related announcement. The overweight children were randomly divided into control (n = 16) and experimental groups (n = 16). The latter group performed Concurrent training for eight weeks, three sessions per week, on non-consecutive days. In the same way as the experimental group,  both before and after the eight weeks of training.  In similar conditions, measurement were performed for both experimental and control groups in two stages (i.e., pre-test and after eight weeks of training). Results: The results of comparing pre- and post-exercise changes in the values for glucose, insulin, ALT, AST, and insulin resistance for the combined exercise training group showed a significant decrease when compared with those for the control group (p < .05); however, the LDL and HDL values did not change significantly across groups (p >.05). Conclusion: In general, the results of this study showed that combined exercises (aerobic-resistance), by reducing the rest levels of liver enzymes, glucose, insulin, insulin resistance, and body composition indexes among 11- to 13-year-old boys, tended to be effective in decreasing the risks of being overweight and in preventing such diseases as obesity, diabetes, and non-alcoholic fatty liver disease.
