The Claim
In healthy young men, performing eccentric exercise prior to 7 days of unilateral leg immobilization attenuates the decline in myofibrillar protein synthesis (MyoPS) observed between days 2 and 7, as evidenced by the absence of significant MyoPS suppression in the immobilized leg of the eccentric exercise group compared to controls, who exhibited a significant reduction in MyoPS in the immobilized leg.
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 certain muscle-lengthening exercises before having one leg kept still for a week, their muscles don’t slow down making new proteins as much as those who don’t exercise — which might help prevent muscle loss.
See the scientific wording
In healthy young men undergoing 7 days of unilateral leg immobilization, prior eccentric exercise is associated with attenuation of myofibrillar protein synthesis (MyoPS) decline between days 2 and 7, as the immobilized leg in controls showed suppressed MyoPS (1.04 ± 0.12%·day⁻¹ vs. 1.86 ± 0.10%·day⁻¹ in non-immobilized; P = 0.002), whereas no significant suppression occurred in the eccentric group (1.49 ± 0.29 vs. 1.90 ± 0.30%·day⁻¹; P > 0.05), indicating sustained anabolic signaling.
What the research says
1 studyThe study found that doing tough leg exercises before immobilizing a leg helped keep muscle-building activity steady, while those who didn’t do the exercises lost muscle-building ability quickly.
