What Systematic recommends
Where to start
- Use a stable surface around standard household-chair height. Stand with your feet about shoulder-width apart and parallel. Maintain full barefoot contact with the floor and awareness of the tripod points of contact through each foot.
- Hold the 5–10 pound object in front of your sternum as a counterweight. Keep the elbows slightly bent. Keep the counterweight under 10 pounds. Keep your feet flat on the ground throughout the movement.
- Lower toward the chair or target surface under control. Lightly touch the surface rather than sitting down fully. Think of the surface as if there were thumbtacks on it. Stand all the way back up after each repetition. Take approximately 3 seconds to lower, pause briefly at the bottom for about 1 second, and take approximately 3 seconds to return to standing.

What changes with age
Research on sit-to-stand compared younger and older adults as they rose from a seat. Older adults often shared the work differently across their joints and used more trunk movement. They also swayed more and coordinated the leg muscles differently.
Sadeh and colleagues (2023) reviewed this research systematically, looking at stability and the strategies people use to rise. Their review supports the Sitting-Rising Test's rationale, but it studied rising from a chair, not from the floor, so it is supporting evidence rather than a test of the Systematic protocol.
Mobility and balance
An efficient way to get up depends on enough usable motion in the hips, knees, ankles, pelvis and spine. Reduced mobility or an altered balance strategy may contribute to needing a hand or knee for support during the Sitting-Rising Test.
The evidence
Each cited source is labeled according to how it supports the particular claim on this page. Direct test evidence, underlying-capacity findings and population reference values are distinguished from Systematic-defined protocols and standards. Historical development notes are retained internally rather than presented as public evidence. A study of an underlying capacity is never presented as validation of the Systematic test itself.

What it found. Compared with younger adults, older adults rising from a seat showed differences in movement speed, trunk use, postural sway and leg-muscle coordination.
What it does not show. It studied sit-to-stand from a chair, not rising from the floor, and it does not test or validate the Systematic Sitting-Rising Test or link these changes to mortality.
The Systematic Healthspan Assessment is a physical baseline. It is not a diagnosis, and it does not estimate a biological age, a disease risk or a lifespan.
