The Claim
In healthy, recreationally active young adults, pre-immobilization leg fat-free mass and quadriceps cross-sectional area are not associated with the magnitude of muscle atrophy following 14 days of unilateral lower limb immobilization.
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 who exercise recreationally, the size of their leg muscles before immobilization does not determine how much muscle they lose after 14 days of leg immobilization.
See the scientific wording
In healthy, recreationally active young adults, pre-immobilization leg fat-free mass and quadriceps cross-sectional area are not associated with the magnitude of muscle atrophy following 14 days of unilateral lower limb immobilization when analyzed across all participants (n=30), suggesting initial muscle size does not predict disuse atrophy in this population.
When a leg is immobilized, muscle cells activate the same breakdown systems regardless of how big the muscle was before, so everyone loses about the same amount of muscle tissue.
What the research says
1 studyThe study found that whether you started with more or less muscle, you lost about the same amount after 14 days of leg immobilization — so having bigger muscles doesn’t mean you lose more.
