| Abstract | ||
| Genetic history, gender, diet, age, hormones and medications all play a big role in determining BMD. Active people generally have a higher bone mineral density (BMD) when compared to their inactive counterparts and the type of exercise also has an impact on BMD. The aim of this investigation was to evaluate changes in bone mineral density at the hip and spine, among female athletes who practiced trained in taekwondo. The sample contained 19 female taekwondo players (n=19), age 17-24. The sample was distributed amongst three groups, those who have participated in taekwondo training for 2-4 years (n= 6), those who participated in taekwondo training for 5-7 years (n= 7), and those who participated in taekwondo training for more than 7 years (n= 6). All participants completed questionnaires to assess their health history, physical activity, dietary intake, and menstrual history. Dual energy x- ray absorptiometry (DEXA) was used to assess bone mineral density (BMD, g/cm2 and BMC, g/cm). Results indicated that there is a significant difference in BMD at the hip and spine for the group three. These results support the relationship between duration of training and BMD in female taekwondo players. In conclusion; participation in taekwondo has showed an increase in BMD. | ||
