Bone Structure and Geometric Properties at the Radius and Tibia in Adolescent Endurance-Trained Cyclists
Objective: To describe cortical and trabecular volumetric bone mineral density (vBMD), bone mineral content (BMC), cross-sectional area (CSA), and bone strength indexes (BSIs) in adolescent endurance-trained cyclists (CYC) and compare them with controls (CON).
Design: Descriptive cohort study.
Participants: Twenty-five male adolescent CYC and 17 CON.
Assessment of Risk Factors: Peripheral quantitative computed tomography was used to evaluate proximal and distal sites of the radius and tibia.
Main Outcome Measures: Total, trabecular, and cortical BMC, vBMD, and CSA were measured. Also, cortical thickness, endosteal and periosteal circumferences, and different BSIs were calculated. Unadjusted analysis of variance and body weight-adjusted analysis of covariance tests were applied between cyclist and control groups.
Results: Cyclists were almost 12% lighter than CON (P
