The Claim
In healthy young men, performing 300 maximal eccentric quadriceps contractions immediately before 7 days of unilateral leg immobilization is associated with higher daily myofibrillar protein synthesis (MyoPS) rates during the first 2 days of disuse compared to no prior exercise, with MyoPS rates 48% greater in the exercised leg (2.57 ± 0.22 vs. 1.89 ± 0.21%·day⁻¹), suggesting that prior muscle-damaging exercise transiently elevates protein synthesis during early disuse.
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.
If young, healthy guys do a tough leg workout right before having one leg immobilized for a week, their muscles in that leg keep building protein faster for the first couple of days compared to if they didn’t exercise first.

What the research says
1 studyThe study found that doing intense leg exercises before immobilizing a leg helps keep muscle-building activity higher for the first couple of days, just like the claim says.
