High-load resistance training elicits greater hypertrophy of both type I and type II muscle fibres than low-load training.
High-load training may be more beneficial for hypertrophying both muscle fiber types.

Two studies reported divergent effects of low-load and high-load resistance training on type I and type II muscle fibre hypertrophy.

- Both low-load and high-load resistance training produce similar increases in muscle size provided the training sets are performed to muscle failure.Strong
- Low-load resistance training may be more effective in producing type I muscle fibre hypertrophy, while high-load may be more effective in producing type II muscle fibre hypertrophy.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
