Abstract

The purpose of this study was to determine the effects of combined exercise and natural protein intake on body composition, maximum muscular strength, muscular endurance, blood components in 20s-obese women. For this purpose, twenty-one 20s-obese women with more 30% of body fat percentage in S city were recruited. They were divided into combine training group(CTG, n=7), combine training＋chicken breast group (CT＋CBG, n=7), combine training＋pork breast group (CT＋PBG, n=7). Combined exercise program(aerobic training and weight training ) was applied, aerobic training equivalent to(Week 1) RPE 1-2, (Week 2-8) RPE 3-7 and weight training equivalent to (Week 1-2) 1RM 30%, (Week 2-4) 1RM 50%, (Week 4-6) 1RM 60%, (Week 6-8) 1RM 70%, 80 minutes a day for 3 days a week in 8 weeks. All date were analyzed by repeated with ANOVA for comparison between groups and interaction and the comparison for within group change was using paired t-test, of SPSS version 18.0 program and significant level was set to .05. The results of this study were as follows:

1. Body Composition

1) Weight was decreased significantly CTG(p<.05), CT＋CBG (p<.001), CT＋PBG(p<.01), It was found significantly different in terms of interaction effect by groups and times(p<.01). It was significantly decreased CT＋CBG, CT＋PBG(p<.05) than CTG.

2) Quantity of body fat % was decreased significantly CTG(p<.05), CT＋CBG (p<.001), CT＋PBG(p<.05), It was found significantly different in terms of interaction effect by groups and times (p<.05) It was significantly decreased CT＋CBG, CT＋PBG(p<.05) than CTG.

3) Quantity of skeletal muscle mass was decreased CTG, increased significantly CT＋CBG (p<.001), CT＋PBG(p<.001), It was found significantly different in terms of interaction effect by groups and times(p<.05) It was significantly increased CT＋CBG, CT＋PBG(p<.01) than CTG.

2. Maximum Muscular strength

1) Leg Press was increased significantly CTG(p<.05), CT＋CBG (p<.001), CT＋PBG(p<.01), It was found significantly different in terms of interaction effect by groups and times (p<.01). It was significantly increased CT＋CBG, CT＋PBG(p<.05) than CTG.

2) Leg Extension was increased significantly CTG(p<.05), CT＋CBG (p<.001), CT＋PBG(p<.001). It was found significantly different in terms of interaction effect by groups and times (p<.05), It was significantly increased CT＋CBG, CT＋PBG(p<.01) than CTG.

3) Chest Press was increased significantly CTG(p<.05), CT＋CBG (p<.01), CT＋PBG(p<.001), It was found significantly different in terms of interaction effect by groups and times (p<.05). It was significantly increased CT＋CBG, CT＋PBG(p<.01) than CTG.

4) Shoulder Press was increased CTG(p<.05), CT＋CBG (p<.001), CT＋PBG(p<.01), It was found significantly different in terms of interaction effect by groups and times (p<.01). It was significantly increased CT＋CBG, CT＋PBG(p<.05) than CTG.

3. Muscular endurance

1) YMCA bench press was increased CTG, CT＋CBG, CT＋PBG It wasn't any significant difference in interaction effect by groups and times.

2) Push-up was increased significantly CT＋CBG (p<.01), CT＋PBG(p<.01), It was found significantly different in terms of interaction effect by groups and times(p<.01), It was significantly increased CT＋CBG, CT＋PBG(p<.05) than CTG.

3) Curl-up was increased significantly CT＋CBG (p<.001), CT＋PBG(p<.001), It was found significantly different in terms of interaction effect by groups and times (p<.01) It was significantly increased CT＋CBG, CT＋PBG(p<.05) than CTG.

4. Blood Components

1) TC was decreased significantly CT＋CBG (p<.05), CT＋PBG(p<.01), It was found significantly different in terms of interaction effect by groups and times p<.05). It was significantly decreased CT＋CBG(p<.05) than CTG and significantly decreased CT＋PBG(p<.05) than CT＋CBG

2) TG was increased CTG but decreased significantly CT＋CBG (p<.05), CT＋PBG(p<.001), It was found significantly different in terms of interaction effect by groups and times (p<.05), It was significantly decreased CT＋CBG, CT＋PBG(p<.05) than CTG.

3) HDL-C was increased significantly CT＋CBG (p<.05 ), CT＋PBG(p<.05 ). It was found significantly different in terms of interaction effect by groups and times (p<.05) It was significantly increased CT＋CBG, CT＋PBG(p<.05) than CTG.

4) LDL-C was decreased CTG, CT＋CBG, CT＋PBG. It wasn't any significantl difference in interaction effect by groups and times
