- Acute high-intensity interval exercise decreased Na+ -K+ -ATPase activity by 12.7% and increased alpha1, alpha2, and alpha3 mRNA expression by 1.4-, 2.8-, and 3.4-fold, respectively.Strong
- Post-training, the acute exercise-induced decline in Na+ -K+ -ATPase activity and increase in alpha1 and alpha3 mRNA persisted.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
