The Claim
A 10-week high-volume resistance training program with adequate protein intake (≥1.8 g·kg⁻¹·day⁻¹) increases whole-body lean mass by approximately 5.5% and thigh muscle volume by 8.3% in healthy young adults, and progressive overload is a potent stimulus for muscle hypertrophy regardless of dietary protein source.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy young adults, a 10-week high-volume resistance training program with at least 1.8 grams of protein per kilogram of body weight per day results in a 5.5% increase in whole-body lean mass and an 8.3% increase in thigh muscle volume. Progressive overload drives muscle growth independently of the protein source consumed.
See the scientific wording
A 10-week high-volume resistance training program with adequate protein intake (≥1.8 g·kg⁻¹·day⁻¹) increases whole-body lean mass by approximately 5.5% and thigh muscle volume by 8.3% in healthy young adults, demonstrating that progressive overload is a potent stimulus for muscle hypertrophy regardless of dietary protein source.
When muscles are repeatedly challenged with heavy lifting, they respond by building more contractile proteins. This happens because the exercise makes muscle cells more sensitive to amino acids from protein intake, which turn on a key molecular switch that tells the cell to make more muscle proteins. Over time, this causes muscle fibers to grow larger, increasing overall muscle mass.
What the research says
1 studyThis study found that when young adults lift weights for 10 weeks and eat enough protein — whether from meat or plants — they gain about 5.5% more muscle mass overall and 8.3% more muscle in their thighs. So yes, the workout itself is what builds muscle, not the type of protein they eat.
