The Claim
Resistance training increases basal (postabsorptive) myofibrillar protein synthesis by 47% in frail and pre-frail older women and does not enhance the postprandial (fed-state) myofibrillar protein synthesis response in this population.
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 frail and pre-frail older women, resistance training raises muscle protein synthesis by 47% when the body is at rest after fasting, but does not increase muscle protein synthesis after eating.
See the scientific wording
Resistance training increases basal (postabsorptive) myofibrillar protein synthesis by 47% in frail and pre-frail older women, but does not enhance the postprandial (fed-state) response, suggesting adaptation occurs primarily at rest rather than after meals.
Lifting weights pulls on muscle fibers, which turns on signals inside the cells that keep the protein-making machinery running even when no food is present. This keeps building new muscle parts during rest, but eating more protein after training doesn't make it work any faster.
What the research says
1 studyStrength training helped older women build more muscle while resting, but didn't make their muscles use protein from meals any better. So, lifting weights helps repair muscles when they're not eating, not when they just ate.
