There is a positive correlation between daily protein intake and changes in skeletal muscle mass.
Increasing protein intake may enhance muscle mass gains in older women undergoing resistance training.
StrongSupportsmedium confidence
A positive correlation was found between daily protein intake (g·kg -1 ·d -1 ) and changes in SMM ( r = 0.23, 95% confidence interval [CI] = 0.03-0.41; p = 0.022).
Why this rating
The correlation is statistically significant and based on a well-defined study population.

- 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
