Bone properties, reflected by speed of sound (SOS), and physical activity levels were examined in overweight (OW) girls (n = 19) and adolescents (n = 22), in comparison with normal-weight (NW) girls (n = 21) and adolescents (n = 13). Moderate-to-vigorous physical activity (MVPA) was higher in NW than in OW in both age groups. Tibial SOS was lower in OW compared with NW in both age groups. MVPA correlated with tibial SOS, once age was partialed out. The results suggest that overweight girls and adolescents are characterized by low tibial SOS, which may be partially attributed to lower physical activity levels.
通过声速（SOS）反映的骨骼特性以及身体活动水平在超重（OW）女孩（n = 19）和青少年（n = 22）中进行了检测，并与正常体重（NW）女孩（n = 21）和青少年（n = 13）进行了比较。在两个年龄组中，NW组的中度至剧烈身体活动（MVPA）均高于OW组。在两个年龄组中，OW组的胫骨SOS均低于NW组。一旦排除年龄因素，MVPA与胫骨SOS相关。结果表明，超重女孩和青少年的特征是胫骨SOS较低，这可能部分归因于较低的身体活动水平。
