碩士 === 國立臺南大學 === 體育學系教學碩士班 === 97 === The purposes of this study are to perceive the effect of tug-of-war training on Bone Mineral Density (BMD) on grade 6 children in sixteen weeks and the differences of BMD between girls and boys. Both training and control group contained 10 boys and 10 girls between the ages 11-12. Training group underwent sixteen-week tug-of-war training, 5 days (around5-8 hours) per week,each time about one hour, while the control group did not participate in any exercise other than the school-required PE classes. Using Quantitative Ultrasound (PEGASUS France), calcaneal bone Broadband Ultrasound Attenuation (BUA) was evaluated before and after training. The results of the study were as follows: 1. The calcaneal bone BUA of training group were obviously higher than the control group (62.26 dB/MHz vs 59.84 dB/MHz) (p<.05). 2. There was no significance between boys and girls in training group, （p>.05）.The BUA values of boys and girls were both significantly higher than those in the control group (p<.05). In conclusion, sixteen-week tug-of-war training will increase childrens’ calcaneal BMD and the effect was obvious in boys as well as girls. Thus, taking part in tug-of-war training is a good method to increase one’s BMD and to reach a higher peak bone mass in order to prevent Osteoporosis.
