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.
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.
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.
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.
What the research says
1 studyOlder 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.
