골프운동이 비만 초등학생의 신체조성과 체력, 혈중지질 및 성장호르몬에 미치는 영향

Abstract

The purpose of the current study was to investigate the effects of golf exercise on the body composition, physical fitness, blood lipids and growth hormone in obese elementary children. Sixteen obese elementary children were divided into exercise (n=8) and control (n=8) groups. The golf exercise program was carried out under the condition of RPE 11-15 for 120 minutes, 3 days a week for 12 weeks. Body composition(body weight, body mass index, percent body fat, body fat mass, skeletal muscle mass, lean body mass, waist-hip ratio, basal metabolism rate), physical fitness(muscle strength, muscle endurance, flexibility), blood lipids(triglyceride, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, fasting glucose) and growth hormone(growth hormone, insulin-like growth factor-1) of all subjects were measured at before and after the program participation. All data were expressed as mean and standard deviation and also independent t-test and paired t-test was performed to test the significant levels of differences within and between groups by using SPSS program. Significance was set at the α=.05. Percent body fat, body fat mass, waist-hip ratio and fasting glucose was significantly decreased within exercise group. Muscle strength(back strength) was significantly increased within exercise group and control group. Flexibility(sit and reach) and insulin-like growth factor-1 was significantly increased within exercise group. Exercise group was shown that there were significant differences of percent body fat, high density lipoprotein cholesterol and fasting glucose, compared with control group. Our findings concluded the severity of obese elementary children. There were significant improvements in percent body fat, body fat mass, waist-hip ratio, muscle strength, flexibility, fasting glucose and insulin-like growth factor-1 in obese elementary children after golf exercise program participation.
