Getting up off the floor: why does it matter for physical function?

The short answer

Getting down to the floor and back up uses no single muscle or joint: it takes usable motion from the ankles to the spine and control of your center of mass. In 4,282 adults aged 46–75, lower scores on the published Sitting-Rising Test were associated with higher natural and cardiovascular mortality. The study did not independently validate Systematic's added bilateral configuration or predict an individual's lifespan.

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. Keep your feet flat on the ground throughout the movement.
  • Take approximately 3 seconds to lower. Pause for approximately 1 second at the bottom. Take approximately 3 seconds to return to standing.

Condensed from the published Development Pathway (The Sitting-Rising Test: Counterbalance Tempo Target Squat). This is a starting point, not a training program or medical advice.

What getting up off the floor measures

The Sitting-Rising Test asks whether you can move between standing and the floor with minimal external support. It does not pick out one muscle or joint. It captures the combined capacity the whole move needs, including dynamic stability and balance as your center of mass travels between the floor and standing.

Two requirements shape it. Mobility: the hips, knees, ankles, pelvis and spine need enough usable motion to reach an efficient way of rising. Stability: the body has to control its center of mass as the base of support changes from the floor to the feet.

A support or balance deduction on the test means you needed an extra strategy somewhere in that transition. Systematic keeps the published scoring structure and adds two standardized foot-forward positions, so it can see side-to-side differences.

Why rising gets harder

A 2023 systematic review compared younger and older adults rising from a chair. Older adults tended to use different joint strategies and more trunk movement. They also swayed more, and their leg muscles worked together differently. Rising from a chair is related to rising from the floor, but it is not the same task.

Pain, joint irritation, swelling, an old injury, altered sensation or protective muscle guarding can reduce how fully muscles are recruited and change the way a person gets up. A low score does not tell you which of these, if any, is at work, and it does not diagnose a muscle-inhibition problem.

What research links it to

In a prospective cohort of middle-aged and older men and women aged 46–75, lower Sitting-Rising Test scores were associated with higher natural and cardiovascular mortality. That is an association across a group, not a prediction for any one person, and the study did not test Systematic's added foot-forward positions.

Reference scores for the test come from 6141 non-athlete adults, with separate distributions for men and women in 15 five-year age groups, reported as quartile bands. Systematic's red, yellow and green bands are Systematic standards, not those published quartiles.

Chair-based tests tell a related story. In the Short Physical Performance Battery, one task is rising from a chair and sitting back down 5 times. Among adults aged 71 and older, each test in the battery and its summary score were strongly associated with self-reported disability. A later meta-analysis of the battery's total score found that the link between middling scores (7-9) and death from any cause was stronger in younger study populations. Neither is evidence about rising from the floor.

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.

    Araújo et al. (2026; published online 2025). Sitting–rising test scores predict natural and cardiovascular causes of deaths in middle-aged and older men and women. European Journal of Preventive Cardiology.

    What it found. In a prospective cohort aged 46–75, lower Sitting-Rising Test scores were associated with higher natural and cardiovascular mortality.

    What it does not show. It did not test Systematic's added foot-forward positions, and it does not show that a low score causes death or predicts it for an individual.

    What it found. Reference scores from 6141 non-athlete adults, reported as quartile bands for men and women in 15 five-year age groups.

    What it does not show. It does not set Systematic's red, yellow and green standards and says nothing about mortality.

    What it found. Older adults rising from a chair tend to use different joint strategies than younger adults, with more trunk movement, more sway and altered leg-muscle coordination.

    What it does not show. It studied rising from a chair, not from the floor, and not the Systematic test.
