Wie leicht Sie sich von einem Stuhl erheben oder vom Boden aufstehen können, ist einer der schnellsten Indikatoren für die Kraft des Unterkörpers, das Gleichgewicht und den Alterungsprozess. Zwei einfache Tests quantifizieren dies. Der 30-Sekunden-Stuhlaufsteh-Test zählt, wie viele Aufstehbewegungen Sie in einer halben Minute ausführen.
Der Sitz-Aufsteh-Test bewertet, wie viel Unterstützung Sie benötigen, um sich auf den Boden zu begeben und wieder aufzustehen, mit einer Punktzahl von null bis zehn. Beide Tests erfassen die Beinkraft und -leistung; in großen Kohorten war eine niedrigere Punktzahl mit einem höheren Risiko für den Verlust der Selbstständigkeit und ein früheres Versterben verbunden. Es ist auch eine Punktzahl, die Sie trainieren können: Durch Belastung der Beine und Übung der Bewegung steigt sie an, ebenso wie die zugrunde liegende Kraft.
Findings & Outcomes
What It Is
The sit-to-stand is the everyday movement that independence depends on: standing up from a chair, and getting up off the floor. Two tests turn it into a number. The 30-second chair stand counts how many times you can rise fully and sit fully in half a minute with your arms crossed, and it tracks lower-body strength closely. The sitting-rising test, or SRT, scores how you get onto the floor and up again, out of ten. It marks off a point for each hand or knee you lean on. Together they measure leg strength and power, balance and flexibility, the capacities that let you stand up under your own control.
This is one of the few self-measures you can also train. The exercises that raise the score, squats, chair rises and step-ups, are the same ones that build leg strength. So a low result is a starting point for training.
How To Do The Test
You need a firm chair without arms, a stopwatch, a little floor space, and, for the floor test, something solid within reach. Do the chair stand first. Attempt the sitting-rising test only if getting down to and up from the floor is already something you do without difficulty.
-
Set the chair against a wall
A straight-backed chair without arms, seat height 17 inches (43.2 cm), the validated height, placed against a wall so it cannot slide. Sit in the middle of the seat, back straight, feet about shoulder width apart and flat on the floor, one foot slightly ahead of the other.
Seat height is part of the test. A soft sofa or a high stool gives a number that will not compare to the published figures.
-
Cross your arms and stand fully, then sit fully
Arms crossed at the wrists against the chest, and there they stay for the whole test. Rise to a full stand, then sit all the way down. Pushing off your thighs measures something else. A full stand and full sit is one repetition.
Count complete stands in 30 seconds. If you are more than halfway up when time is called, that counts as a stand. If you need your arms to rise at all, the score is zero. A zero is a valid result, so write it down.
Compare the count to your age and sex. Rikli and Jones published reference ranges for the chair stand from the Senior Fitness Test. For a man in his early sixties the middle range is roughly 14 to 19 stands. For a woman it is roughly 12 to 17. Both drift lower each decade. Falling under your band marks reduced lower-body capacity now, and it does not lock in a decline. The US Centers for Disease Control uses the same test inside its STEADI fall-risk screen, flagging a count below the age and sex average as increased risk. The full age and sex table sits alongside the fall-risk work on our balance and falls page.
The sitting-rising test is harder. You lower yourself all the way to the floor and rise back to standing, loading the legs and hips through a far greater range than a chair stand. It was built and studied in a Brazilian exercise-medicine cohort.
-
Start standing, on a firm and non-slippery surface
Barefoot or in grippy footwear, in loose clothing, on a floor that will not slide. A firm rug over a hard floor is safer than bare tile. From standing, lower yourself to sitting cross-legged on the floor, then rise back to standing, using as little support as you can.
Do it at your own unhurried pace. Speed is not scored. Have a wall or a sturdy chair within reach.
-
Score the way down and the way up, out of ten
Start from five points for sitting down and five for standing up. Take off one point each time you use a hand, a forearm, a knee, or the side of a leg for support. Take off half a point if you lose balance or wobble noticeably.
Add the two halves for a score from 0 to 10. A ten means you got down and up with no support at all; leaning on one hand each way lands around eight.
What The Score Means
A low score is a signal about the whole lower body, and it does not pin down any one cause. What each study can show depends on how it was built. The mortality associations are cohort findings. A low score partly reflects the health a person already has, not only their future risk. Each association below also has a specific confounder. The training result is pooled from randomized trials, which is why it can speak to cause. The chair stand is also part of the standard test batteries geriatric medicine relies on, so its meaning is well understood.

Progress Markers
Lowest performers on leg tests including five chair rises were 4.2 to 4.9 times as likely to be disabled in four years
In older people who started out with no disability, those who did worst on a set of simple leg tests, including standing from a chair five times, were four to five times more likely to be disabled four years on.
Guralnik and colleagues followed 1,122 community-dwelling adults aged 71 and older who reported no disability and could walk half a mile and climb stairs. Baseline testing included standing balance, a timed 8-foot walk and five timed chair rises. At four years, the lowest performers were 4.2 to 4.9 times as likely to have activities-of-daily-living or mobility disability, and intermediate performers 1.6 to 1.8 times, than the highest performers, adjusted for age, sex and chronic disease.
Who this may not transfer to:Community-dwelling adults aged 71 and older who began with no disability, so it speaks to older people, not to the middle-aged.

Each point on the 10-point sitting-rising test predicts about 21% lower death risk over six years
People who could lower themselves to the floor and stand back up with little or no support lived longer than those who needed hands, knees or a lot of help. Each point out of ten was worth roughly a fifth lower risk of dying over about six years.
Brito and colleagues scored 2,002 adults (68% men) from 0 to 5 for sitting and 0 to 5 for rising, subtracting a point for each hand or knee used and summing the two for a 0 to 10 score. Over a median 6.3 years there were 159 deaths (7.9%). Adjusted for age, sex and body mass index, hazard ratios ran 5.44, 3.44 and 1.84 across the score bands from lowest to highest, and each single-point increment carried a 21% survival improvement.
Who this may not transfer to:A single Brazilian exercise-medicine cohort skewed 68 percent male, so the size of the association in women and in other populations is less certain.

Deaths ran from 3.7% at a perfect sitting-rising score to 42.1% at the lowest over twelve years
A larger and longer follow-up of the same test found the same pattern for deaths from natural and heart-related causes: the lowest scorers were several times more likely to die over the next twelve years than those who rose from the floor cleanly.
Araujo and colleagues followed 4,282 adults (68% men) for a median 12.3 years, during which 665 died (15.5%). Death rates across the five score groups were 3.7%, 7.0%, 11.1%, 20.4% and 42.1% from best to worst. Adjusted for age, sex, body mass index and clinical variables, the lowest group had a hazard ratio of 3.84 for natural mortality and 6.05 for cardiovascular mortality against the highest.
Who this may not transfer to:Same Brazilian research group and clinic population, again 68 percent male, so it confirms the pattern within one setting, not across independent populations.

A leg-function battery timing five chair rises predicted death and nursing-home entry in over 5,000 elders
A brief set of movement tests that includes standing up from a chair five times predicted who would die or enter a nursing home, and it sorted risk even among people who said they had no trouble getting around.
Guralnik and colleagues assessed lower-extremity function in over 5,000 adults aged 71 and older across three communities using standing balance, a timed 8-foot walk and time to complete five chair rises, summed into a performance scale. Both the individual tests and the summary scale predicted short-term mortality and nursing-home admission in multivariate models, and distinguished a gradient of risk among high-functioning people who reported almost no disability, information self-report alone did not capture.
Who this may not transfer to:More than 5,000 adults aged 71 and older across three communities, so it applies to older populations, not younger ones.

Failing the five-times sit-to-stand carried 4.22 times the fall odds and 24.70 times the disability odds over three years
People who could not stand from a chair five times, or who were slow at it, were more likely to fall and much more likely to lose independence in everyday tasks over the next three years.
Zhang and colleagues recorded five-times sit-to-stand ability and time in 948 adults aged 60 and over. At three years, inability to complete the test predicted falls with an odds ratio of 4.22, described by the authors as marginal, and predicted disability far more strongly: odds ratios of 24.70 for basic and 17.10 for instrumental activities of daily living. Taking longer than 16.6 seconds carried an odds ratio of 4.22 for instrumental-activity disability, and 13.7 to 16.6 seconds an odds ratio of 2.49.
Who this may not transfer to:Sex breakdown not reported, and a slow chair-rise time can reflect conditions that independently raise fall and disability risk, so read it as a marker, not a cause.

Muscle And Strength
Resistance training improves chair-rise performance (SMD -0.94) and leg strength (SMD 0.84)
Unlike some markers you can only read, this one moves with training. Lifting two or three times a week made older adults noticeably better at rising from a chair, stronger in the legs, and a little faster on their feet.
Liu and Latham's Cochrane review pooled 121 randomized trials of progressive resistance training in older people (6,700 participants), typically two to three sessions a week at higher intensity. Getting out of a chair improved with a standardized mean difference of -0.94 (11 trials, 384 participants; a lower time is better, so the negative sign is a gain), muscle strength with an SMD of 0.84 (73 trials), physical ability with an SMD of 0.14 (33 trials), and gait speed by 0.08 m/s (24 trials).
Who this may not transfer to:Pooled across many trials, protocols and older-adult populations, so the average effect may be larger or smaller in a specific program or person.
Because the chair stand responds to training, a low score is a reason to load the legs, squats, sit-to-stand repetitions and step-ups two or three times a week, not only a warning to note. Improving the score improves the underlying strength it reads, which not every self-measure can offer.

Measurement And Diagnosis
The 30-second chair stand is a rough leg-strength proxy, correlating r = 0.78 in men and 0.71 in women
How many times you can stand up from a chair in 30 seconds, arms crossed, tracks your measured leg strength closely and gives nearly the same result if you repeat it. That is why counting stands is a fair stand-in for lower-body strength.
Jones, Rikli and Beam tested 76 community-dwelling adults (mean age 70.5) on two 30-second chair-stand trials and two maximal leg-press trials on separate days. Test-retest intraclass correlations were 0.84 (men) and 0.92 (women). Chair-stand count correlated with weight-adjusted leg press at r = 0.78 (men) and 0.71 (women), and scores fell across each decade from the 60s to the 80s and were lower in less active people, supporting it as a valid strength measure.
Who this may not transfer to:A small validation sample of generally active older adults, so the strength of the correlation may differ in frailer or younger people.

Chair-stand cut-points for ages 60 to 94, from 2,140 adults, mark the strength tied to independence
There are published age and sex targets for the chair stand that mark the leg strength linked to staying physically independent into later life. Scoring below your band flags reduced capacity, not a guaranteed decline.
Rikli and Jones derived criterion-referenced fitness standards from 2,140 moderate-functioning older adults in a cross-sectional Senior Fitness Test database, anchored to a measure of physical independence and to longitudinal capacity-and-aging research. The standards give chair-stand cut-points by sex for ages 60 to 94, with reliability and validity indicators between 0.79 and 0.97.
Who this may not transfer to:Cut-points derived from moderate-functioning older adults aged 60 to 94, so they describe that group, not a tested forecast for a given individual.

How it works
Leg power fades earlier and faster than strength, and drives how well you rise from a chair
Standing up quickly needs power, the ability to produce force fast, and power fades sooner and faster than raw strength as we age. That is a big part of why rising from a chair gets hard, and why quick, deliberate stands are worth practicing, not only slow heavy ones.
Reid and Fielding review evidence that lower-extremity muscle power declines earlier and more steeply than strength with advancing age, and that peak power has emerged as a more discriminant predictor of functional limitations. Their working model treats lower-limb power as a key link between muscle impairment, functional limitation and disability, which is why the speed of a chair stand, not only whether it can be done, carries information.
Who this may not transfer to:A mechanistic synthesis of human data on older adults, so it explains why rising behaves as it does, not quantifying an effect in one defined group.
Because power fades faster than strength, training the chair stand as a brisk, controlled movement, standing up with intent, not grinding slowly, targets the capacity that ages fastest, alongside heavier lower-body work for strength.

Two limits apply to all of these findings. First, these tests blend several capacities. A low SRT can come from tight hips as much as from weak legs, and the chair stand leans on stand-up technique alongside strength. Second, these are observational studies, so the mortality links are associations and cannot establish cause.
A low score is a reason to train the legs, and to see a clinician if it arrived quickly or came with pain, weakness or numbness.
How To Improve It
The strength and power this test measures respond well to training. The core of it is the movement itself, loaded. Sit-to-stand repetitions are an exercise as well as a test: stand up and sit down from a firm chair, arms crossed, for two or three sets. Make it harder over time by slowing the lowering, pausing at the bottom, or holding weight against your chest. Add squats to a chair or bench, step-ups onto a stair, and split squats, two or three sessions a week, hard enough that the last few repetitions are difficult. Because leg power fades faster than raw strength with age, practice some stands briskly and with intent, standing up fast under control, alongside the slower heavy work.
For the floor test, practice the transitions directly. Get onto the floor and back up a few times with support nearby, leaning on your hands less as it gets easier. The full case for loading the legs, and the free bodyweight version, is on our resistance training page. The balance side, weight shifting and single-leg work, is on balance and falls.

The Chinese Medicine View
The tradition maps the standing body across three organ systems, a different vocabulary from muscle physiology for describing where the body tends to give way with age. The Spleen governs the muscles and flesh (脾主肌肉). So weak, wasted or heavy limbs are understood through Spleen Qi, the body's vital energy, and its work of turning food into usable substance. The Kidney governs the bones (腎主骨) and stores the Essence that makes marrow, the classical seat of the low back and knees and of strength declining with age. The Liver governs the sinews (肝主筋), the tendons and ligaments that give movement its quality, kept supple by Liver Blood. Setting this map against what an older person actually reports is an interesting parallel, not confirmation that the three-organ framework is physiologically accurate.
Standing itself has a place in the tradition as rooted Qi. The legs are the foundation, and internal arts train sinking the weight and the breath low, into the lower dantian, so the stance is settled and connected to the ground. The Lingshu describes what happens as the deeper reserves empty. When the sea of marrow is insufficient, the head spins, the ears ring, the shins ache, and the person wants to lie down. As a description of an unsteady, weak-legged older body, it fits.
The tradition also does not ask the same effort of everyone. The Neijing holds that exertion consumes Qi (勞則氣耗). So someone depleted, tired out of proportion to what they did, is pointed toward short and frequent practice that stops well short of exhaustion. If you have a practitioner, ask them about this, because the answer depends on your pattern.
Cautions For This Practice
Everything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.
Do the floor test only if it is safe for you
Work on firm, non-slip ground with a wall or a solid chair to steady yourself, and have someone nearby the first time. If deep bending of the hips or knees is painful, use the chair stand alone and leave the floor test out. The same goes if you have had a recent hip or knee replacement, or an acute back or joint problem.
Stop for any warning sign and get support for the chair stand if you are unsteady
Stop any test for chest pain or pressure, sudden breathlessness, dizziness, or a fast or irregular heartbeat, and seek medical advice. If you have fallen in the past year or feel unsteady, do the chair stand beside a counter with something to hold. Treat that unsteadiness as a reason to be assessed by a clinician.
A score reflects capacity, it does not diagnose
Build up gradually. Start with fewer repetitions and less load than you think you can manage, and add slowly.
Start slow, be smart, read the research, and consult a professional if you have any concerns. This is here to inform your choice, not make it for you.
Common Questions
What is a good 30-second chair-stand score for my age?
The number that matters most is your own, tracked over time. A single pass mark tells you less than the way your 30-second count moves over months. Retest under the same conditions, same chair height, arms crossed, and watch the trend. A count that climbs means the training is working; one that drops is a reason to look at why.
What does the sitting-rising test actually measure?
Getting down onto the floor and standing again draws on leg strength, leg power, balance, flexibility and body weight all at once. That breadth makes it a fast screen but a poor way to pinpoint any single weak capacity. In the same cohort, 4,282 adults were followed a median of twelve years. Deaths ranged from about 4% in those who scored a perfect ten to 42% in the lowest group. The pattern held for heart-related deaths too.
If I practice the test, does my health actually improve, or just my score?
Both improve, because the chair stand is built on lower-body strength. Across pooled randomized trials, resistance training gave a moderate to large improvement in rising from a chair, alongside large gains in leg strength. Whether a higher score then lowers a specific future risk, such as a fall, is a separate question the training trials were not built to answer.
Why is standing up getting harder as I get older?
A large part of it is muscle power, the ability to produce force quickly. That power fades earlier and faster with age than raw strength does. Rising from a chair or the floor is a burst of power, so it is where the decline shows first. Training the power back, not just slow heavy lifting, is what keeps you rising; the resistance training page has the how.
Is the chair stand or the floor test better for me?
The chair stand is safer, easier to score consistently, and enough for most people to track lower-body strength over time. The floor test is a harder challenge that also captures flexibility and balance and adds getting off the floor, a skill that matters if you fall. If you are older, unsteady, or managing a joint problem, the chair stand alone is the sensible choice. If you move well and want the fuller picture, the floor test adds information the chair stand cannot.
