摘要
目的：本研究旨在比较男性公路自行车运动员（RC n = 39）、山地自行车运动员（MC n = 30）和对照组（C n = 27）的腰椎骨矿物质密度（BMD）和股骨颈骨矿物质密度（FBMD），并确定与同组参与者 BMD 相关的因素。方法使用 DXA 测量 BMD、脂肪量（FM）和无脂肪量（FFM）。钙摄入量（Cal）、运动能量消耗（EEE）和能量可用性（EA）通过自我报告问卷进行评估。此外，还采集了循环激素样本。VO2max 是通过 Cycloergometric 测试估算的。结果显示在对体重进行调整后，骑自行车者的 LSBMD（RC 0.98 ± 0.12；MC 0.98 ± 0.10 g/cm2）明显低于 C（1.11 ± 0.10；p BMD 结果显示，骑自行车者与 C 相比无明显差异（p = 0.213）。骑自行车者的 EA（千卡/FFM/天）与骑自行车者不同（p BMD（R = 0.561，R = 0.656，分别为 R = 0.561、R = 0.656，p BMD（R = 0.554，p BMD 在 MC 中发现（R = 0.464，p 2max），RC 中的 LSBMD（R = -0.418，p BMD 在 MC 中发现（R = 0.605，p 结论：RC和MC的LSBMD均低于C，而两组自行车运动员之间没有发现差异。与 BMD 相关的因素是多方面的，因测量地点而异，并且在 RC、MC 和 C 中可能有所不同。
Bone Mineral Density in Mountain, Road Cyclists and Untrained Controls: Exercise, Diet and Hormones.
Purpose: The aim of the study was to compare bone mineral density (BMD) in the lumbar spine (LSBMD) and the femoral neck (FBMD) in male road cyclists (RC n = 39), mountain cyclists (MC n = 30) and controls (C n = 27) and to determine the factors associated with BMD in the same group of participants. Methods: BMD, fat mass (FM) and fat-free mass (FFM) were measured using DXA. Calcium intake (Cal), exercise energy expenditure (EEE) and energy availability (EA) were assessed using self-reported questionnaires. Samples for circulating hormones were also obtained. VO2max was estimated by a cycloergometric test. Results: After adjustment for body mass, in cyclists LSBMD (RC 0.98 ± 0.12; MC 0.98 ± 0.10 g/cm2) was significantly lower than in C (1.11 ± 0.10; p < .001), while FBMD resulted in no significant difference in cyclists compared to C (p = 0.213). EA (kcal/FFM/day) was different in cyclists and in C (p < .05). In C, EEE and EA were positively associated with LSBMD (R = 0.561, R = 0.656, respectively, p < .01), whereas only EA was associated with FBMD (R = 0.554, p < .05); a positive association between EA and FBMD was found in MC (R = 0.464, p < .05). A negative relationship between VO2max and LSBMD in RC (R = -0.418, p < .05) and a positive one between EEE and LSBMD in MC were found (R = 0.605, p < .001). CaI, free testosterone and cortisol were unrelated to BMD. Conclusion: Both the RC and MC had lower LSBMD than C, whereas no difference was found between the two groups of cyclists. The factors associated with BMD are manifold, vary in relation to the measurement site and are likely different in RC, MC and C.
期刊介绍：
Research Quarterly for Exercise and Sport publishes research in the art and science of human movement that contributes significantly to the knowledge base of the field as new information, reviews, substantiation or contradiction of previous findings, development of theory, or as application of new or improved techniques. The goals of RQES are to provide a scholarly outlet for knowledge that: (a) contributes to the study of human movement, particularly its cross-disciplinary and interdisciplinary nature; (b) impacts theory and practice regarding human movement; (c) stimulates research about human movement; and (d) provides theoretical reviews and tutorials related to the study of human movement. The editorial board, associate editors, and external reviewers assist the editor-in-chief. Qualified reviewers in the appropriate subdisciplines review manuscripts deemed suitable. Authors are usually advised of the decision on their papers within 75–90 days.
