Aims: The aim of this study was to evaluate the effect of 8 weeks of concurrent training on serum leptin levels, body composition, and lipid profiles of inactive men with overweight.
Materials & Methods: Thirty young men with an average age of 19 to 25 years old and an average body mass index of 25 to 28 kg / m2 were randomly divided into three groups: Concurrent, intermittent aerobics - sauna, continuous aerobic - sauna and exercise strength- sauna (each group was 10). The subjects performed 3 sessions of aerobic and strength training per week on individual days, and then 2 sessions per week, supplementing the sauna program on twenty days for 20 -30 minutes in a dry bath with a temperature of 80 degrees Celsius. Blood samples were taken from subjects in fasting mode in two stages, 72 hours before and after 8 weeks of training. Serum lipid profiles, leptin and body composition were evaluated by ANOVA and Tukey's post hoc test
Findings: The results showed a significant decrease after exercise aerobic exercise, continuous aerobic exercise and baseline strength training, serum levels of leptin, total cholesterol, triglyceride, low density lipoprotein cholesterol, lipoprotein a and body fat percent (p≤0.05). And high density lipoprotein cholesterol (p <0.05). These changes were more frequent in the aerobic exercise group, continuity and strength, but this difference was not significant between the groups (p≤0.05).
Conclusion: The results of this study indicated that continuous aerobic exercise, continuation and strength training simultaneously with the sauna had a favorable effect on lipid profile and body composition and serum leptin concentrations. These changes were more common in the aerobic training group.
