Changes in muscle thickness at VL70 were observed in both RPE groups, with a small between-group effect size.
Both RPE levels can lead to changes in muscle thickness, though the effect size is small.
StrongSupportsmedium confidence
For VL70, changes in MT was observed in both groups (4-6 RPE: 1.20 [-1.05-3.45], 7-9 RPE: -0.08 [-2.22-2.05]), with small between-group effect size (g = 0.21 [-0.13-0.56]).

- 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
