Abstract:

BACKGROUND: Peak bone mass obtained in adults has been shown to be of great significance for preventing senile osteoporosis.
OBJECTIVE: To investigate the effect of track and field on bone mineral density of college students and the difference in bone mineral density between sexes.
METHODS: Totally 86 Han sophomore students from Zhengzhou Universities, Henan Province, including 26 track and field athletes (male: 14; female: 12), and 60 non-athletes (male: 30; female: 30). The bone mineral densities of the distal radius 1/3, right femoral neck, right femur Ward triangle, right femur trochanter and right calcaneus were measured by Prodigy Advance dual energy X-ray instrumentation (GE company, US). Descriptive Statistics and Independent-Sample Test were analyzed by the SPSS13.0 software.
RESULTS AND CONCLUSION: For same gender, the bone mineral densities of the distal 1/3 radius, right femoral greater trochanter and right calcaneal bone in athletes were significantly higher than those in non-athletes (P < 0.05); the bone densities of the right femoral neck and right femur Ward triangle in athletes were significantly higher than those in non-athletes (P < 0.01). In the same group, the males had a significantly higher bone density of the right calcaneus than females (P < 0.05). These results manifest that track and field can significantly improve the bone mineral density of college students, and exerts different effects on different limb parts, which may be related to the sport characteristics. Besides, futher investigation on the sex difference in calcaneus bone density is indispensable.
