Comparison of muscle mechanical and histochemical properties between young and elderly subjects.

Abstract

We examined age-related human muscle fiber changes and their relation with maximal power scaled to muscle volume (specific power). Fiber type distribution and cross sectional area (CSA) were determined from m. vastus lateralis in 7 young (YS; 29.6 +/- 5 years) and 7 elderly subjects (ES; 74.3 +/- 3 years). Muscle volume and mean CSA of the thigh were… (More)
