The Effect of Detraining on Lipoprotein and Body Composition after 8 Week Calorie Restriction and Different Level of Aerobic Exercise among Obese Middle-aged Women / 農村醫學 地域保健

ABSTRACT

OBJECTIVES: This study is to identify the effect of detraining on lipoprotein and body composition after 8 week calorie restriction and different level of aerobic exercise among obese middle-aged women. METHODS: The 30 middle-aged women whose body fat were over 30% were randomly allocated into three groups of control, exercise group of 40% VO2max level, and exercise group of 60% VO2max level. All the participants were taught to record their calorie intake and restrict daily 500kcal intake. After eight-week exercise and daily 500kcal restriction, their body compositions and blood lipid levels were measured again. RESULTS: The weight, BMI, body fat, total cholesterol, triglyceride, and LDL-cholesterol levels showed significant decreases after eight-week exercise and calorie restriction in the two exercise groups. However, detraining tended to increase them again after detraining of 4 weeks, and even more after 8 weeks. CONCLUSIONS: Detrainging after calorie restriction and exercise tended to increase levels of indices for body composition and lipoprotein among obese middle-aged women.
