The Effect of Concurrent Exercise Order (Resistance and Endurance) on Lipid Profile, Leptin Serum and Insulin Resistance Index in Overweight Women

Purpose: The purpose of this study was the effect of concurrent exercise order on lipid profile, leptin serum and insulin resistance index in non-athlete overweight women. Methods: Thirty female students (age = 23.2 ± 2.4 year, BMI = 27.87 ± 1.3 kg/m2) volunteered to participate in this study and were randomly divided into three groups of 10 people taking the Concurrent Endurance-Resistance (CER), Concurrent ResistanceEndurance (CRE) and Control (C). Two exercise groups performed the same concurrent exercise, but the order of endurance and resistance exercise were different in two groups. Fasting blood samples were collected before and after completion of the exercise. The paired sample t-test was used to determine differences within a group, and variation between groups analysis of variance (ANOVA) and LSD were used. Results: The implementation of a concurrent exercise session in two exercise groups except for the indicators of HDL that there was no significant change, caused to significantly decreases in TC, TG, LDL, insulin, insulin resistance indices and leptin serum that this rate of changes was significant compared with the control group. But no significant difference was observed between implementation of two methods of concurrent exercise. In addition, the control group did not change significantly in none of the variables. Conclusion: Although the implementation one session of a combination of resistance and endurance exercise improves lipid profile, insulin resistance index and leptin serum but the effectiveness of two methods of concurrent endurance-resistance and resistance-endurance were similar.
