Aim: Exercise reduces weight and prevents obesity. The aim was to evaluate the effect of eight weeks of aerobic-yoga training on serum irisin, lipid profile and body composition of obese women.Method: Subjects were 16 obese female volunteers (age: 33.82±3.91 years, weight: 78.2±2.72 kg, BMI: 30.22±1.03 kg/m2) who were randomly divided into two groups of exercise (n = 8) and control (n = 8). The experimental group performed eight weeks of aerobic-yoga training, three sessions per week, 60 minutes per session, and with an intensity of 65-75% of the reserve heart rate. Blood samples were taken 24 hours before and 48 hours after exercise, and serum Irisin, lipid profile and body composition were measured. Independent t-test and ANCOVA were used to evaluate the mean difference before and after eight weeks of aerobic-yoga training. Significance level was considered P <0.05.Results: Serum irisin levels (P<0.0001) and HDL (P=0.003) significantly increased after eight weeks of aerobic-yoga training. Meanwhile, weight (P<0.001), WHR (P<0.001), BMI (P<0.0001), fat percentage (P<0.0001), fat mass (P<0.0001), LDL (P<0.001), VLDL (P<0.0001), TG (P=0.027) and cholesterol (P=0.002) significantly reduced after 8 weeks of aerobic-yoga training compared. LBM (P = 0.579) had no significant difference after eight weeks of aerobic-yoga training.Conclusion: Aerobic-yoga exercise reduces weight and improves irisin, body composition and blood lipid profile in obese women.
