The Effect of Eight Weeks Concurrent Training and Supplementation of L_Arginine on Stress Oxidative and Lipid Profile in Elderly Men

  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. 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. 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). 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.
