The objective of this research was to investigate the effect of Taekwondo training for 16 weeks on obese elementary school students’growth hormone and bone mineral density(BMD). The study was conducted on male obese elementary school students who residein D metropolitan city and have body mass index (BMI) higher than 25%. The whole subject group had no particular diseases anddid not regularly exercise more than twice a week. Based on basal movement, low section, Taekwondo gym and form pattern, theTaekwondo train program was composed of total 16 weeks; 4 weeks of introductory phase, 4 weeks of maintenance phase and 4weeks of improvement phase one and two, respectively. BMD was analyzed using Dual-energy X-ray absorptiometry standard protocol.
As a result, growth hormone was not significantly difference in group and exericse effects. In BMD, there was a significant differencebetween the two groups in BMD lumber spine(LS). In BMD-femur, there was a significant difference in the group (p<0.01) and time(p<0.05). In body composition, there was no statistically significant difference between body mass, body mass index, body fat massand muscle volume. In conclusion, since 16 weeks of Taekwondo training had a positive effect on elementary students’ metabolicsyndrome index, BMD and postural balance.
