Figure 5.

FAT oxidation rate normalized to fat‐free mass of 11 nonsarcopenic (NS) (open circles, dashed lines) and 11 sarcopenic (S) (solid circles, solid lines) individuals (A) fasted, postprandial, and during (B) submaximal aerobic exercise and leg extensions to exhaustion. FAT oxidation was calculated for 30 min prior to and 180 min post‐consumption of a CHO‐rich meal at 15‐ and 30‐min intervals, over 2‐min intervals during aerobic exercise, and over quintiles during anaerobic exercise. Differences between NS and S were determined with independent samples t‐tests. * indicates differences between groups (P ≤ 0.05). At baseline and throughout the resting period, FAT oxidation was greater in NS compared with S. There were no differences between groups during exercise. Values are means ± 95% confidence intervals.
