Abstract
Exercise time to exhaustion during moderate intensity exercise significantly improved after a high-fat diet compared to a high-carbohydrate diet.
- Trained cyclists (n = 5) followed either a high-fat or high-carbohydrate diet for two weeks.
- Muscle glycogen content was lower after the high-fat diet at the onset of both high and moderate intensity exercises.
- Despite lower glycogen levels, exercise time to exhaustion during moderate intensity exercise was longer after the high-fat diet.
- Endurance enhancement during moderate intensity exercise after the high-fat diet was linked to a lower respiratory exchange ratio.
- A decreased rate of carbohydrate oxidation was observed after the high-fat diet, indicating changes in energy utilization.
