High carbohydrate (CHO) feeding resulted in elevated pre-exercise glycogen on DAY 3 (713 ± 60 mmol·kg−1 dw) compared to a moderate CHO diet on DAY 3 (435 ± 57 mmol·kg−1 dw, P <0.001), but not on DAY 5 (409 ± 40 mmol·kg−1 dw).
For athletes, a high CHO diet can significantly increase glycogen levels before exercise, but this effect may not persist with repeated loading.

More from this paper
- Muscle glycogen utilization was higher on DAY 3 (600 ± 86 mmol·kg−1 dw) compared to both DAY 1 (340 ± 84 mmol·kg−1 dw) and DAY 5 (350 ± 51 mmol·kg−1 dw, P <0.001).Strong
- Repeated muscle glycogen supercompensation is not possible, even with a high CHO diet and light training, but performance enhancement is maintained.Strong
