The Effect of Six-Week Aerobic Exercise Combined with Green Tea Consumption on PON1 and VO2max Increase and Apelin, Blood Pressure, and Blood Lipids Reduction in Young Obese Men

Obesity is among the major health problems; therefore, the present study aimed to investigate six-week aerobic training with green tea supplementation on some cardiovascular markers in young obese men. After measuring physiological markers, 57 overweight men in the age range of 28-35 years old were randomly divided into four groups:  aerobic exercise + green tea consumption (AE+GE; n=10), aerobic exercise (AE; n=10), green tea consumption (GE; n=10), control group (C; n=10) in which members of this group neither participated in aerobic exercise nor consumed green tea. Eighteen sessions of aerobic exercises were held over the six-week study period (three 45-minute training sessions per week). The variables were examined before the intervention and 48 hours after the last training session and tea consumption. Body Mass Index and fat percentage significantly decreased in AE+GE, AE, and GE groups (P=0.001 for all). Aerobic power significantly increased in AE+GE (P=0.001) and AE (P=0.001) groups. Systolic blood pressure significantly decreased in AE+GE (P=0.006) and AE (P=0.002) groups. Diastolic blood pressure significantly decreased in AE+GE (P=0.001) and AE (P=0.015) groups. Total cholesterol and low-density lipoprotein decreased in AE+GE (P=0.001), AE (P=0.004, P=0.002) and GE groups (P=0.02; P=0.012). High-density lipoprotein significantly increased in AE+GE (P=0.001) and AE groups (P=0.04). Apelin levels decreased in AE+GE (P=0.001) and AE groups (P=0.001). Paraoxonase-1 significantly increased in AE+GE (P=0.001), AE (P=0,001), and GE (P=0.30) groups. Aerobic exercise and green tea consumption effectively controlled cardiovascular risk factors in obese or overweight people. However, combining aerobic exercise and green tea consumption led to better results.
