Description
1 study reviewed
In plain English

Healthy older adults who complete a 24-week online program of resistance training and protein guidance show measurable gains in leg strength and ability to move functionally.

See the scientific wording

A 24-week online lifestyle intervention combining resistance training and protein advice can be delivered to healthy older adults with measurable improvements in leg strength and functional mobility, though the absence of a control group limits causal interpretation.

Why this might work

When older adults perform resistance exercises, the force on their muscles triggers biochemical signals that tell muscle cells to build more contractile proteins. Eating more protein, especially with the amino acid leucine, provides the raw materials and further activates these signals. Over time, muscle fibers grow larger and stronger, allowing the legs to generate more force and move more efficiently during daily tasks like standing up from a chair.

  1. Study: O.4.1-5 An online lifestyle intervention consisting of resistance exercise and advice on protein intake improves leg muscle strength and physical functioning in older adults

    An online program that taught older adults to do strength exercises and eat more protein helped them get stronger and stand up from a chair faster over six months. But since there was no group that didn’t do the program, we can’t be 100% sure the program caused the improvement.
