The Claim
After 14 days of unilateral knee immobilization in healthy young men, 99 muscle proteins are differentially expressed, with 76 upregulated and 23 downregulated, indicating a substantial remodeling of the skeletal muscle proteome.
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 men, 14 days of immobilizing one knee changes the levels of 99 proteins in the skeletal muscle, with 76 increasing and 23 decreasing, resulting in a significant shift in the muscle's protein profile.

When a muscle is not used, its energy needs drop, so it shuts down its power plants (mitochondria), which causes harmful molecules to build up. This stress signals the muscle to break down its own proteins faster than it makes new ones, and it also changes how its genes are read, leading to a complete overhaul of its protein makeup.
What the research says
1 studyAfter two weeks of keeping one leg still, scientists found nearly 100 muscle proteins changed their levels—some increased to break down muscle and handle stress, others decreased for energy production. This proves the muscle is actively reorganizing itself, not just wasting away passively.
