Table 1. Subject Characteristics.
Subjects were presumably healthy, premenopausal women (N = 13). Body composition was determined by dual energy x-ray absorptiometry (DXA). Quadriceps cross-sectional area (CSA) was determined as the anatomical area of the quadriceps after removing area of non-muscle tissues.
