The effect of eight weeks of aerobic-yoga training on serum Irisin level, lipid profile and body composition of obese women

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.

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.

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.

Aerobic-yoga exercise reduces weight and improves irisin, body composition and blood lipid profile in obese women.
