The Claim

In adults aged 60–85 years, the combination of resistance training and daily protein supplementation for 3 months is associated with greater improvements in lean mass and muscle strength compared to resistance training or protein supplementation alone.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In adults aged 60–85, doing resistance training and taking daily protein supplements for three months leads to greater increases in lean mass and muscle strength than doing either one alone.

See the scientific wording

In adults aged 60–85 years, combining resistance training with daily protein supplementation for 3 months is likely associated with greater improvements in lean mass and muscle strength than either intervention alone, suggesting a synergistic effect.

Why this might work

Lifting weights signals muscles to build more protein, and eating extra protein gives the body the raw materials to do it. Together, they make muscles grow bigger and stronger because the body makes more protein than it breaks down.

    For older adults, lifting weights alone helps build muscle, and protein shakes alone don’t do much — but doing both together makes muscles grow even more than just one alone.
