Repeated muscle glycogen supercompensation is not possible, even with a high CHO diet and light training, but performance enhancement is maintained.
Athletes should be aware that while performance may improve, they cannot expect to continually increase glycogen stores through repeated carbohydrate loading.

Repeated muscle glycogen supercompensation is not possible, even when subjects consume a high CHO diet and maintain only light training.

- 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
- 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

- 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
