Abstract
A significant difference in fat content ingested before the duathlons was observed (p < .05).
- Time to complete the duathlon did not differ between the high-carbohydrate (HC) and high-fat (HF) diet trials.
- Carbohydrate oxidation rates were higher during the HC-diet trial compared to the HF-diet trial (p = .006).
- Fat oxidation rates were higher in the HF-diet trial than in the HC-diet trial (p = .001).
- Blood glucose concentration was higher immediately after the duathlon in the HC-diet trial than in the HF-diet trial and remained elevated 1 and 2 hours after the duathlon (p < .05).
- No differences in perceived exertion were found between the dietary trials.
