Muscle Area, Muscle Mass and Muscle Power in a Pre-pubertal and an Elderly Population
Many studies reporting muscle-bone relationships use muscle area as a surrogate measure for muscle strength. The purpose of this study is to compare muscle-bone relationships in children and in an aging population using three different muscle measures as predictors to estimate bone strength of the tibia: Cross-sectional muscle area (CSMA) from 66% distal tibia slice measured by pQCT; leg lean mass (LLM) measured by whole body DXA; and muscle power (Power) measured by ground reaction force from a two-footed jump. Bone strength (polar strength strain index, pSSI) of the tibia was measured by pQCT at the 20% distal tibia site. In growing children, the amount of muscle (CSMA, LLM) may influence bone strength more than function of the muscle (power) while in adults, the amount of muscle may not be as influential as the function of the muscle.
