운동유형이 노인 여성의 체력과 균형 및 BDNF, IGF-1, Cortisol변화에 미치는 영향

Abstract

This study aims to examine the effects of exercise types on physical fitness, static balance, and changes in BDNF, IGF-1, and cortisol, to analyze physical fitness necessary for daily life, balance good to prevent falling, and changes in related factors of brain derived neurotrophic factors, and to provide suitable exercise programs by conducting badminton, yoga, and elastic band exercise for 12 weeks with elderly women. Finally, the following results were obtained.

1. For changes in physical fitness in elderly women according to exercise types, the badminton group had statistically significant difference in chair stand, arm curl, 2-min walk, and 244cm up-and-go. The yoga group had statistically significant difference in sit-and-reach and back scratch. The elastic band exercise group had statistically significant difference in chair stand, arm curl, and 244cm up-and-go. For between-group difference, there was statistically significant difference in arm curl between the badminton group and the yoga group.

2. For changes in static balance in elderly women according to exercise types, the badminton group had statistically significant difference in Med-Lat, Ant-Post, and velocity moment of normal standing eye open, normal standing eye close, tandem eye open, one leg right standing eye open, and one leg left standing eye open. The yoga group had statistically significant difference in Med-Lat and velocity moment of normal standing eye close, Ant-Post of tandem eye open, and Ant-Post of one leg right standing eye open. The elastic band exercise group had statistically significant difference in Med-Lat and Ant-Post of normal standing eye open, Ant-Post of normal standing eye close, Med-Lat, Ant-Post, and velocity moment of tandem eye open, and Med-Lat of one leg right standing eye ope. For between-group difference, there was statistically significant difference in normal standing eye open between the badminton group and the yoga group and between the elastic band exercise group and the yoga group. There was statistically significant difference in Med-Lat and Ant-Post of tandem eye open between the badminton group and the elastic band exercise group. There was statistically significant difference in Med-Lat of one leg right standing eye open between the badminton group and the yoga group; in Ant-Post of one leg right standing eye open between the yoga group and the elastic band exercise group and between the badminton group and the elastic band exercise group; and in velocity moment of one leg right standing eye open between the badminton group and the yoga group. There was statistically significant difference in Ant-Post of one leg left standing eye open between the badminton group and the yoga group

3. For changes in BDNF, IGF-1, and cortisol in elderly women according to exercise types, the badminton group had statistically significant difference in BDNF, IGF-1, and cortisol; the yoga group had statistically significant difference in cortisol; and the elastic band exercise group had statistically significant difference in BDNF and IGF-1. However no statistically significant difference was found between groups.
