Abstract
This study examined the association between types of sports and bone mineral density (BMD) in female high school athletes. The subjects composed of 108 female athletes of judo, taekwondo, weight lifting, swimming, long distance running, and controls aged 15 to 18 years. Areal bone density in lumber spine (L2-L4), femoral neck, femoral trochanter, and Ward's triangle were measured by using duel energy x-ray absorptiometry(DEXA). General linear models were used to test mean differences for BMDs across different types of sports after adjustment for age, menstrual abnormality, age at menarche, and body mass index. Duncan’s post-hoc tests were also used to detect mean differences across different sports categories. Judo female athletes had the greatest BMD of lumbar spine (1.25 g/cm2), while Taekwondo female athletes had the greatest BMD of proximal femur (1.02 g/cm2). After adjustment for multiple risk factors, there were statistical mean differences in lumbar spine (p =.007), proximal femur (p = .01), and trochanter (p =.002), respectively, across different types of sports. Both Judo and Taekwondo athletes had greater BMDs in lumber spine compared with athletes from long distance running or swimming (p< .001). Similarly, Taekwondo and Judo athletes had greater BMDs in proximal femur compared with athletes from swimming or long distance running (p< .001).
