Effects of aerobic exercise intensity on insulin resistance, renin-angiotensin Ⅱ and C-reactive protein in patients with metabolic syndrome
ABSTRACT
The purpose of this study was to investigate the effects of aerobic exercise intensity on insulin resistance, renin-angiotensin Ⅱ and CRP in patients with metabolic syndrome. The subjects of this study were middle-aged women with metabolic syndrome. The subjects were randomly divided into the following three groups: moderate-intensity group(n=9, 40~60% of the heart-rate-reserve(HRR) method), high -intensity group(n=9, 60~80% of the HRR), and control group(n=8). The exercise groups were invited to participate in an exercise program consisting of a treadmill walking and/or running for 12weeks with frequency of 5times per week. The following results were found: 1. The obesity index(weight, percent body fat, waist circumstance), systolic blood pressure, diastolic blood pressure, fasting glucose, t-chol, TG, LDL-C were significantly decreased than those after treatment in both moderate and high-intensity exercise groups before treatment. The HDL-C levels were significantly increased than those after treatment in both moderate and high-intensity exercise groups before treatment. 2. The Insulin, Insulin resistance, renin-angiotensin Ⅱ levels, C-reactive protein were significantly decreased than those after treatment in both moderate and high-intensity exercise groups after treatment. Consequently, the moderate and high-intensity aerobic exercise during 12weeks effect positively on metabolic syndrome risk factors, insulin resistance, inhibition of renin-angiotensin Ⅱ activation and decrease of C-reactive protein of patients with metabolic syndrome.
Key words: exercise intensity, aerobic exercise, metabolic syndrome, insulin resistance, renin-angiotensinⅡ, C-reactive protein
