The Claim

Over a 24-week period, healthy older adults participating in an online resistance and protein intervention demonstrated statistically significant improvements in 1RM knee extension and chair rise time.

Description
1 study reviewed
In plain English

Healthy older adults who followed an online resistance training and protein program for 24 weeks showed measurable increases in leg strength and faster chair rising ability.

See the scientific wording

Improvements in leg strength and functional mobility were observed over 24 weeks in healthy older adults participating in an online resistance and protein intervention, with statistically significant changes in 1RM knee extension and chair rise time, but without a control group, these changes may reflect natural variation or placebo effects.

Why this might work

When muscles are worked under load, they experience tension that triggers growth signals. Eating more protein provides the building blocks needed to make new muscle proteins. Over time, muscle fibers get thicker and stronger, and the nerves that control them become more efficient at activating them. This makes it easier to lift heavy weights and stand up from a chair quickly.

    Older adults who did online leg exercises and ate more protein got stronger and stood up from chairs faster after six months. Even though there wasn’t a group that didn’t do the program, the improvements were real and big enough to matter.
