The Claim
Myofibrillar protein synthesis demonstrates higher rates of increase during the initial week of resistance training adaptation compared to the tenth week, despite continued training.
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.
When you start lifting weights, your muscles build new protein faster in the first week than they do after 10 weeks, even if you keep training.
See the scientific wording
Myofibrillar protein synthesis shows greater increases during initial resistance training adaptation (week 1) compared to later stages (week 10) despite continued training.
What the research says
3 studiesThe study shows that muscle-building protein production is higher in the first week of weight training compared to the tenth week, even though people kept exercising, which matches the claim.
The study shows that muscle building from exercise is stronger at the start of training and gets weaker after 10 weeks, even if you keep exercising, which matches the claim.
Study: Fasted‐state skeletal muscle protein synthesis after resistance exercise is altered with training
The study shows that when you start lifting weights, your muscles build protein faster at first compared to later, even if you keep training hard.
