Abstract

The purpose of this study was to investigate the effects of different intensity aerobic exercise trainingon metabolic syndrome risk factor and heart rate recovery in women with abdominal obesity. Twenty-fourparticipants(age 39.1±4.0 years; waist circumference of =85 cm) were randomized to equal volumes of eithercontinuous moderate exercise(60% of VO2max) or aerobic interval training(80% of VO2max) 3 times a week for12 weeks. In addition, both groups were encouraged to maintain daily caloric intake and physical activity as usual. VO2max, heart rate recovery of 1 minute immediately after peak exercise test, waist circumference, blood pressure,lipid profiles, glucose, and homeostasis model assessment for insulin resistance were measured at baseline, at themid-point and after the exercise program. The main results of the study were as follows. With respect tometabolic risk factors, the moderate-intensity exercise group had a significantly higher improvement(p<0.001) inwaist circumference than the high-intensity exercise group. The high-intensity exercise group had a significantlyhigher improvement(p=0.022) in cardiorespiratory fitness than the moderate-intensity exercise group. Regarding oftraining intensity, heart rate recovery response were tended to increase following the training programs. It wasconcluded that both moderate- and high-intensity exercise training would induce significant improvements in severalof metabolic risk factors and heart rate recovery in women with abdominal obesity.
