The Claim
In the absence of resistance training, even with adequate protein intake (>1.6 g/kg/day), trained male futsal players do not experience significant gains in lean body mass or muscle thickness over an 8-week period, regardless of 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.
Trained male futsal players who do not do resistance training do not gain muscle or increase lean body mass over 8 weeks, even if they consume more than 1.6 grams of protein per kilogram of body weight daily, no matter what type of protein they eat.
See the scientific wording
In the absence of resistance training, even with adequate protein intake (>1.6 g/kg/day), trained male futsal players do not experience significant gains in lean body mass or muscle thickness over 8 weeks, regardless of protein source.
Without resistance training, muscle fibers do not experience enough force to trigger the signals that tell the body to build new muscle, even when plenty of protein is available. The body only uses protein to make muscle when it senses that the muscles are being stressed by heavy loads.
What the research says
1 studyEven when futsal players ate plenty of protein, they didn’t get bigger or stronger muscles over 8 weeks — because they didn’t lift weights. Protein alone isn’t enough to build muscle without training.
