Lower vertebral bone density in male long distance runners.

摘要: Bone density in 13 male long distance runners (28.7 +/- 1.2 yr, 67.6 2.0 kg) and 11 nonrunners (26.8 1.3 71.0 2.2 was compared. measured at the lumbar spine mid-tibia using dual photon absorptiometry mid-radius single absorptiometry. Runners (mean weekly training 92.2 6.3 km) had significantly lower (P less than 0.05) vertebral bone mineral (1.12 0.03 g.cm-2) (1.24 0.04 g.cm-2). Tibial radial did not differ between groups. Daily calcium intake for (1,373 486 mg) (1,267 236 exceeded RDA. The results of this study suggest that running may lead to decreased density. hormonal changes occur with endurance contribute decrease.
