The effect of green tea supplement on some metabolic indicators and body composition after eight weeks of moderate intensity rhythmic aerobic exercise in obese women

Exercising with herbal supplements is recommended as an important way to control and prevent obesity. The aim of the study was to evaluate 8 weeks moderate intensity rhythmicaerobic exercise with green tea supplementation on some of metabolic and body composition indices of obese women.

In the semi-experimental study, 30 inactive obese women, purposefully, based on body mass index (BMI) were randomly divided into 3 groups of 10 people. They were rhythmic aerobic exercise with green tea supplement group (Experimental1, BMI:35.69±2.28 kg/m2), rhythmic aerobic exercise group (Experimental2, BMI:36.18±2.25 kg/m2) and control group (BMI:34.65±3.02 kg/m2). The rhythmic aerobic exercise protocol was performed 8 weeks and 3 sessions per week for both experimental groups. The supplement group received one capsule containing 500 mg of green tea daily. Metabolic and body composition indices were measured in pre-test and post-test stages. Paired t-tests, covariance analysis and bonferroni post hoc test were used for data analysis (p<0.05).

Eight weeks of rhythmicaerobic exercise with and without green tea supplement led to significant decrease (p<0.05) in body weight and BMI (both of them respectivly 3%,2%), waist circumference(respectivly 4%,1%), serum glucose(respectively 7%,5%), triglyceride (respectively 11%,4%) and malondialdehyde (MDA) (respectivly 25%,9%).

However, rhythmic aerobic exercise improved body composition and serum levels of triglycerides, glucose and MDA in obese women; rhythmic aerobic exercise with green tea supplement had a more significant effect on the waist circumference, serum levels of triglyceride and MDA.
