Table 2.
Metabolic measures during last 30 min of exercise in GLUFRU and GLU. Values are mean (SEM). GLUFRU = glucose-fructose co-ingestion, GLU = glucose alone ingestion.
| GLUFRU (n = 15) | GLU (n = 15) | p Value | |
|---|---|---|---|
| Carbohydrate requirements (g) | 34.0 ± 2.9 | 37.8 ± 5.3 | 0.46 |
| Carbohydrate oxidation (mg·kg−1·min−1) | 18.1 ± 0.8 | 24.5 ± 0.8 | <0.001 |
| Fat oxidation (mg·kg−1·min−1) | 5.2 ± 0.2 | 2.6 ± 1.2 | <0.001 |
| Glucose appearance, Ra (mg·kg−1·min−1) | 7.0 ± 0.4 | 7.3 ± 0.4 | 0.53 |
| Glucose disappearance, Rd (mg·kg−1·min−1) | 7.8 ± 0.3 | 7.6 ± 0.5 | 0.57 |
| Metabolic clearance rate, MCR (mg·kg−1·min−1) | 6.0 ± 0.3 | 5.9 ± 0.4 | 0.80 |
