摘要：

Bone mineral content (BMC) and bone mineral density (BMD) were measured by dual-energy X-ray absorptiometry Lunar DPX-NT, SV 4.0 in 23 professional male cyclists (age: 8.5 +/- 3.9 yr; height: 179 +/- 6.8 cm; weight: 70.9 +/- 7.1 kg(-1)). Eight subjects had normal L1-L4 T-score values (-0.19 +/- 0.62) band 15 had low values (-1.57 +/- 0.45). Correlations between: L1-L4 T-scores and body weight, fat mass (FM) and % FM (r=0.40, p <0.05; r=0.65, p <0.001: 1-0.59, 0.59, p <0.01). Regression analysis: L1-L4 T-score and FM (R-2 = 0.42; p < 0.001); total BMC and fat-free mass (FFM) (R-2 = 0.60; 1) < 0.0001); and total BMD and BMI (R-2 = 0.25; p < 0.05). Climbers had lower arms BMD (0.85 +/- 0.04; p < 0.05). Flat-terrain cyclist had lower right leg FFM (9.7 +/- 0.8 kg; p < 0.05). Time trialists had higher body weight (76.7 +/- 4.4 kg; p < 0.05), total FFM (68.3 +/- 4.7 kg), total BMC (3.1 +/- 0.3; p < 0.03), right and left leg BMC (0.60 +/- 0.1; 0.60 +/- 0.1; p < 0.05), and spinal BMD (1.09 +/- 0. 1; p < 0.05). In conclusion, two-thirds of professional cyclists had abnormally low BMD Values.
