Muscle fat oxidative capacity not impaired by age but by inactivity
May 31st, 2004
Muscle fat oxidative capacity is not impaired by age but by physical inactivity. "The study aimed at determining whether aging and/or sedentariness impairs muscle fat oxidative capacity (OXFA) and whether this was associated with increased risk to develop insulin resistance. We first examined muscle mitochondrial functions, OXFA and insulin sensitivity (ISI; evaluated during an oral glucose tolerance test) in a cross-sectional study with 32 sedentary (S) and endurance-trained (T), young (Y) and elderly (E) men (24.2±2.6 vs 66.6±3.2 years)," scientists writing in the FASEB Journal report. "As for mitochondrial functions, OXFA was...
