| Abstract |
The purpose of this study was to evaluate the effect of walking exercise and detraining on body composition (weight, %fat, BMI), blood lipids (TC, TG, LDL-C, HDL-C) and stress hormone (cotisol, epinephrine, norepinephrine). Thirty six obese women were recruited from the public health center and welfare center. They were divided into experimental group (n=18) and control group (n=18). Experimental group was trained for 8 weeks (4 times/week) and control group was not trained for 8 weeks, detrained for the following 4 weeks and 8 weeks. Data were analyzed with two-way ANOVA and one-way ANOVA by repeated measure. The results were as follows. Weight, %fat, BMI, TG and LDL-C were improved pre and post walking exercise in experimental group. But, these increased again after 4 weeks and 8 weeks detraining. It was found that the previous exercise effect of weight, %fat, BMI, TG and LDLC was totally lost when detraining for 4 weeks. And, cortisol was not changed in experimental group and increased in control group. TC, HDL-C, epinephrine and norepinephrine were not changed between group, between time, group and time interation. In conclusion, walking exercise was effective to improve body composition, blood lipids and stress hormones. But, exercise should be started again within at least 4 weeks after detraining |
