The Claim
Following 14 days of unilateral knee immobilization in healthy young men, 322 biological processes are altered in skeletal muscle, with 77% positively enriched for cellular stress and proteolysis and 23% negatively enriched for mitochondrial organization and energy metabolism.
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 322 biological processes in the leg muscle: 77% increase in processes related to cellular stress and protein breakdown, and 23% decrease in processes related to mitochondrial function and energy production.

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 turns on cleanup systems that break down muscle proteins, and the muscle gets smaller as a result.
What the research says
1 studyAfter two weeks of keeping a leg still, the muscles changed in ways that show they’re breaking down proteins and dealing with stress, while turning down their energy production—like a cell switching from working out to just surviving.
