Exercise and Weekly Sirolimus (Rapamycin) in Older Adults: RAPA‐EX‐01 Randomised, Double‐Blind, Placebo‐Controlled Trial
The study used the 30-second chair stand test to measure how well older adults improved with exercise, and because it could detect changes, it shows the test works well for this purpose.
Validity and Responsiveness to Change of the 30-Second Chair-Stand Test in Older Adults Admitted to an Emergency Department.
The study tested the 30-second chair stand test in older adults and found it really does reflect how well they can do daily activities and move around, especially when they're sick.
Sensor-Integrated Chairs for Lower Body Strength and Endurance Assessment
The study tested a smart chair that counts how many times an older adult can stand up in 30 seconds, and it found the results matched well with manual counting. This supports the idea that the 30-second chair test is a reliable way to measure leg strength in older people.
