Fat-free mass normalized to height is a statistically predictive determinant of maximum parallel barbell back squat strength.
Practitioners should focus on increasing fat-free mass to enhance barbell back squat strength.
StrongSupportsmedium confidence
Multiple regression revealed only 1 statistically predictive determinant: fat-free mass normalized to height (standardized estimate ± SE = 0.6 ± 0.3; t(16) = 2.28; p = 0.037).
Why this rating
Based on the use of multiple linear regression analysis in a controlled study.

- 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
