BONE MINERAL DENSITY IN ATHLETE WOMEN. ANALYSIS OF THIRTY-NINE CASES.


Abstract: Objective: Exercises, especially sports have an effective role in increasing of Bone Mineral Density (BMD). This study surveyed the bone density in athlete women compared to Iranian standard BMD at the same age and sex. Methods: This study was a prospective survey on thirty-nine athlete women between 20 to 30 years old. Subjects were selected randomly in six different athletes groups including basketball, volleyball, tennis, badminton, swimming and running. BMD was measured with a Hologic 1000 plus machine by Dual Energy X-Ray Absorptiometry (DEXA) method for the lumber spine (L1, L2, L3, L4, L1-4) and the femoral neck (Neck, Trochanter, Intertrochanter, Ward, Total). Data were treated by paired t test. Results: There were significant differences between BMD of athlete women groups with Iranian normal population for both femoral neck (p = 0.03) and spine (p = 0.001). The BMD of femoral neck was significantly higher in badminton (p = 0.0095), volleyball (p = 0.03), basketball (p = 0.0003) athlete women compared with Iranian standard. The BMD of lumbar spine (L1-L4) was significantly higher in basketball (p = 0.0003) and volleyball (p = 0.0001) athlete women compared with Iranian standard.
