Abstract

The purpose of this study was to investigate the effects of taekwondo training period on body composition and fundamental physical fitness in elementary students. The subjects of this study were 30 elementary school students between 4th and 6th grade. The subjects were divided into three groups; A groups(Training for less than 1 year), B groups(Training for 1 year to 2 years), and C groups(Training for over 2 years). and the subjects trained an all three groups after school. The dependent variables were body composition; fat mass, percent fat, muscle mass, waist hip ratio and physical fitness; muscular strength, muscle endurance, cardiorespiratory endurance, flexibility, power, agility. One-way ANOVA with repeated measurements was used to test the hypothesis in this study. The statistical significance level of this study was α=.05. The results of study were as follows; It was shown that the group with less than 1 year training had a lower body composition than the group with 1-2 years training, and the group with more than 2 years training. The group with more than 2 years training had a higher skeletal and muscle volume and waist-hip ratio(WHR) was lower in order of the group with less than 1 year training, the group with 1-2 years training and the group with more than 2 years training. In fundamental physical fitness, it was shown that the group with more than 1 year training had a higher muscle strength, the group with more than 2 years training had a higher muscle endurance and agility followed by the group with 1-2 years training and the group with less than 1 years. In conclusion, it was shown that the taekwondo training period of after school give a good influence to body composition and physical fitness.
