The effect of aerobic exercise in water with and without green tea consumption on kidney function in sedentary postmenopausal women

Obesity in patients is followed by decreased kidney function and leads to renal damage in healthy people. The aim of this study was to investigate the effect of aerobic exercise with and without green tea consumption on kidney function in sedentary postmenopausal women. Out of 60 volunteers, 29 sedentary postmenopausal women with a body mass index higher than 25 kg/m2 were randomly divided into three groups, exercise, supplement and exercise+supplement. Aerobic exercise program was performed for 8 weeks, 3 sessions per week and each session for 45 minutes at 65-75 % of maximum heart rate. Supplement groups consumed 6 g of green tea powder in 600 ml of almost boiling water (80 °) daily and one hour before their meals for 8 weeks. Combined group performed exercise and consumed supplement, simultaneously. In supplement group, creatinine levels (p=0. 048) decreased significantly; While none of the variables in exercise group (uric acid (p=0. 432), urea (p=0. 681) and creatinine (p=1) ) and exercise+supplement group (uric acid (p=0. 597), urea (p=0. 270) and creatinine (p=0. 235) ) had no significant change. Between groups changes in any of the variables was not significant too. Eight weeks of aerobic exercises in water alone and in combination with green tea consumption did not improve renal function in obese and overweight postmenopausal women, while green tea consumption alone decreased serum creatinine and improved renal function.
