What the chair-stand test captures
In a 1994 study of more than 5,000 adults aged 71 and older from three communities, lower body strength and endurance were measured by the time taken to rise from a chair and sit back down 5 times. It was one part of a short battery that also timed walking and tested standing balance.
The authors concluded that performance measures like these can describe older people across a broad range of lower body function.
How it relates to daily function
Each test in that battery, the chair stand included, was strongly associated with people's own reports of disability, and so was the battery's summary score.
The tests also added something self-report did not. Among people who described the same level of function, physical performance still differed in a systematic way with age, and the authors suggest performance and self-report complement each other.
What studies show about survival
Among people at the high end of function, who reported almost no disability, performance scores in the 1994 study distinguished a gradient of risk for death.
A 2016 meta-analysis looked at the whole Short Physical Performance Battery, which adds the chair stand to balance and walking. Compared with total scores of 10-12, scores of 4-6 were associated with higher all-cause mortality (odds ratio 2.14, 95% CI 1.92-2.39) after adjustment for age, sex and BMI. That is a result for the battery score, not for an isolated chair stand.
A 2010 systematic review included chair rising as one of four separate measures, alongside grip strength, walking speed and standing balance, in observational studies of mortality in community-dwelling people. These are associations, not causes, and the five-chair-rise task is a different movement from the floor-based Systematic sitting-rising test.
In a meta-analysis of five studies (28,036 participants), the slowest quarter of chair-rise performance had higher all-cause mortality than the fastest quarter (adjusted HR 1.96, 95% CI 1.56–2.45, adjusted for age, sex where relevant, and body size). Estimates varied substantially between studies (I² 81.9%), so the pooled result is not a universal risk estimate.
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.

Underlying-capacity evidence New source
Guralnik et al. (1994). A short physical performance battery assessing lower extremity function: association with self-reported disability and prediction of mortality and nursing home admission. Journal of gerontology.
What it found. In adults aged 71 and older, each test (including five timed chair rises) and the summary score were strongly associated with self-reported disability, and performance scores distinguished a gradient of mortality risk among people reporting almost no disability.
What it does not show. It does not show that the chair stand alone carries the battery's results, that it applies to younger adults, or anything about the floor-based sitting-rising test.

Underlying-capacity evidence New source
Pavasini et al. (2016). Short Physical Performance Battery and all-cause mortality: systematic review and meta-analysis. BMC medicine.
What it found. Lower total Short Physical Performance Battery scores were associated with higher odds of all-cause mortality: scores 4-6 versus 10-12 gave an odds ratio of 2.14 (95% CI 1.92-2.39) after adjustment for age, sex and BMI.
What it does not show. It is about the total battery score, not an isolated chair stand, and it does not validate the Systematic battery.

Underlying-capacity evidence New source
Cooper et al. (2010). Objectively measured physical capability levels and mortality: systematic review and meta-analysis. BMJ (Clinical research ed.).
What it found. In five studies (28,036 participants), the slowest quarter of chair-rise time had higher all-cause mortality than the fastest quarter (adjusted HR 1.96, 95% CI 1.56–2.45), with substantial heterogeneity between studies (I² 81.9%).
What it does not show. It is a population-level observational association, not a universal risk estimate, and it says nothing about the floor-based Systematic Sitting-Rising Test.
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.
