The Claim
In pre-conditioned older women, 8 weeks of resistance training alone improves muscle mass and strength, but additional gains during a subsequent 12-week training phase require nutritional support such as whey protein supplementation.
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 older women who have already been physically active, 8 weeks of strength training increases muscle mass and strength, but more gains after that require adding whey protein to their diet.
See the scientific wording
In pre-conditioned older women, resistance training alone for 8 weeks improves muscle mass and strength, but further gains require additional nutritional support such as whey protein supplementation during the subsequent 12-week training phase.
When older women lift weights, their muscles experience stress that signals the need to grow. Eating whey protein after training delivers a surge of leucine, which turns on a molecular switch in muscle cells that tells them to build more protein. This switch stays active longer when protein is present, allowing muscles to add more mass and strength over time than they could with training alone.
What the research says
1 studyIn older women who already work out, adding whey protein to their diet while lifting weights helps them build more muscle and get stronger than just lifting weights alone — so yes, they need the protein to keep improving.
