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).
Athletes may experience higher glycogen utilization during exercise on the third day of a high CHO diet, which could impact performance.

More from this paper
- 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).Strong
- Repeated muscle glycogen supercompensation is not possible, even with a high CHO diet and light training, but performance enhancement is maintained.Strong

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
