Figure 4.

Carbohydrate (CHO) 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. CHO 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). CHO oxidation was greater in S at baseline and at min 120–180. There were no differences between the groups during aerobic exercise. During anaerobic exercise, CHO oxidation was greater in NS at 60–80% time to exhaustion compared with S. Values are means ± 95% confidence intervals.
