Abstract
The rate of muscle glycogen resynthesis was similar for both carbohydrate and nonnutritive sweet placebo trials.
- Eight male cyclists participated in a controlled exercise study.
- Muscle biopsies were taken at multiple time points to assess glycogen levels.
- Initial carbohydrate feeding during exercise did not significantly influence glycogen resynthesis during the first 2 hours of recovery.
- After a 24% carbohydrate supplement was ingested, muscle glycogen resynthesis rates increased comparably in both trials.
- Significantly higher serum glucose and insulin levels were observed during the nonnutritive sweet placebo trial.
