The Claim

A daily protein intake of approximately 1.5 g/kg body weight, achieved through habitual diet plus 35 g of whey protein supplementation on training days, enhances skeletal muscle mass and strength gains in pre-conditioned older women undergoing resistance training.

Cause and effect
1 study reviewed
In plain English

Older women who regularly perform resistance training and consume about 1.5 grams of protein per kilogram of body weight daily, including 35 grams of whey protein on training days, experience increases in skeletal muscle mass and strength.

See the scientific wording

A daily protein intake of approximately 1.5 g/kg body weight, achieved through habitual diet plus 35 g of whey protein supplementation on training days, is sufficient to enhance skeletal muscle mass and strength gains in pre-conditioned older women undergoing resistance training, aligning with current recommendations for elderly populations.

Why this might work

When older women consume whey protein after training, the leucine in it triggers a signal in their muscle cells that tells them to build more protein. This happens faster and stronger when the muscle has just been worked, so the muscle grows bigger and stronger over time.

  1. Study: Effects of Whey Protein Supplementation Pre- or Post-Resistance Training on Muscle Mass, Muscular Strength, and Functional Capacity in Pre-Conditioned Older Women: A Randomized Clinical Trial

    Older women who already work out and drank a protein shake on workout days gained more muscle and got stronger than those who didn’t, even if they ate the same amount of protein on non-workout days. This shows the shake helped.
