Abstract

The purpose of this study was to determine the effect of Taekwondo exercise on body composition, neurotransmitter and brain nerve growth factor in middle-aged women. For this purpose, 26 middle-aged women in Y city were recruited. They were divided into Taekwondo group(TG, n=13) and control group(CG, n=13). Taekwondo exercise program was applied exercise equivalent to RPE 11~12(Week 1-4) and exercise equivalent to RPE 13~15(Week 5-8) and exercise equivalent to RPE 13~15(Week 9-12) 50 minutes a day for 5 days a week in 12 weeks. All date were analyzed by two-way repeated with ANOVA for comparison between groups and interaction and the comparison for within group change was paired t-test of SPSS package 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 TG(p<.05) but increased significantly CG(p<.01). It was significantly different in terms of interaction effect by groups and times(p<.001). 2) Quantity of body fat % was decreased significantly TG(p<.05) but increased CG. It was significantly different in terms of interaction effect by groups and times(p<.05).

3) Quantity of lean mass was decreased TG but increased CG. It wasn't any significantly different in terms of interaction effect by groups and times.

4) BMI was decreased significantly TG(p<.05) but increased significantly CG(p<.05). It was significantly different in terms of interaction effect by groups and times(p<.01).

2. Neurotransmitter

1) Dopamine was increased TG and CG. It wasn't any significantly different in terms of interaction effect by groups and times.

2) Serotonin was increased significantly TG(p<.05) and increased CG. It was significantly different in terms of interaction effect by times(p<.05). But it wasn't any significantly different in terms of interaction effect by groups and times. 3) IL-6 was decreased significantly TG(p<.01) and increased CG. It wasn't any significantly different in terms of interaction effect by groups and times.

4) Cortisol was decreased TG but no change CG. It was significantly different in terms of interaction effect by groups (p<.01). But it wasn't any significantly different in terms of interaction effect by groups and times.

3. Brain Nerve Growth factor

1) BDNF was increased significantly TG(p<.05) but decreased CG. It was significantly different in terms of interaction effect by groups and times(p<.01).

2) IGF-1 was increased TG but decreased CG. It wasn't any significantly different in terms of interaction effect by groups and times.
