Changes in vastus lateralis muscle thickness did not statistically differ between training programs with different proximities to failure.
Practitioners may consider that varying proximity to failure does not significantly impact muscle thickness gains in trained individuals.
StrongQualifiesmedium confidence
Equivalence testing confidence intervals crossed both g = 0.0 and g = ±0.20 thresholds; suggesting changes in VL50 MT and VL70 MT did not statistically differ between groups but were also inconclusive.

- 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
