Association of Physical Activity with Bone Mass in Swimmers
游泳選手體能活動與骨質密度之相關
摘要
Background and Purpose: Up to now controversial reports have been published in regard to the beneficial effects of swimming, a non-weight-bearing activity, on bone mass. Therefore, we attempted to investigate the effects of competitive swimming practice on the bone mineral density (BMD). Methods: To examine the issue, we measured femoral neck and lumbar spine BMD in nineteen male college competitive swimmers. Their age (M±S. D.), height and weight were 20.5±1.1 yrs, 174.2±5.8cm, 72.3±9.7 kg respectively. Results: At vertebral sites (1.148±0.095g/cm^2), the male swimmers had significantly greater BMD than the non-exercisers (1.00±0.77 Z-Score, p＜.001). At femoral neck sites (1.091±0.111g/cm^2), the male swimmers had significantly greater BMD than the non-exercisers (2.69±l.08 Z-Score, p＜.00l). Conclusion: These results suggest that long-term swimming exercise may be beneficial in the prevention or therapy of osteoporosis and that its potential usefulness in this regard is greater for femoral neck sites than for lumbar spine site.
