Metabolic adaptation
Ingestion of a 6.4% carbohydrate-electrolyte solution (CHO) significantly increased plasma glucose oxidation during running (65 ± 20 g.h−1) compared to water (W) (42 ± 16 g.h−1; p < 0.01).
For athletes, consuming carbohydrates before and during exercise can enhance glucose oxidation and potentially improve performance.
StrongSupportsmedium confidence
A significant main treatment effect was found for plasma glucose oxidation during both running (65 ± 20 vs. 42 ± 16 g.h−1; p < 0.01).
Why this rating
Based on the controlled trials conducted with male subjects.

More from this paper
- The contribution to total carbohydrate oxidation was significantly greater with CHO than W during running (33 ± 4% vs. 23 ± 3%; p < 0.01) and cycling (36 ± 5% vs. 22 ± 3%; p < 0.01).Strong
- Ingestion of CHO did not result in a significant reduction in mixed muscle glycogen utilization compared to W.Strong
