Abstract: Objective To study the influences of long-term basketball training on bond mineral density(BMD)at different parts of hoopman in college.Methods Fifteen male basketball athletes (training for 10 years) from Institute of Physical Education were selected as training group,fifteen non-sports male college students (with the same age )were used as non-training group.The BMD of both left and right femur of different parts of femurs(neck and ward)，the spine and the L₂,L₃,L₄ of spine and both left and right forearm and the levels of serum testosterone (T),cortisone (COR),parathyroid hormone (PTH),and bone da protein (BGP) were determined by dual energy X-ray absorptiometry (DXA) of whole body and irradiation immunity of serum.Results The peak values of BMD of L₂,L₃,L₄，right forearm,neck of left and right hip joint in training group were significantly higher than those in non-training group (P<0.01 or P<0.05).The levels of serum T,CDR,PTH and BGP at rest had no significant differences between two groups(P>0.05).Conclusion Long-time basketball training can effectively increase the BMD of L₂,L₃,L₄ of spine,right forearm,left and right hip joint.But it has no effect on the serum T,COR,PTH,and BGP at rest.
