Between 1998 and 2023, researchers at Brazil’s Clinimex exercise medicine clinic tracked 4,282 adults aged 46 to 75 through a remarkably simple physical test: sit down on a bare floor, then stand back up, using as little support from your hands, knees, or forearms as possible. A study published in June 2025 in the European Journal of Preventive Cardiology found that middle-aged and older adults who completed this movement cleanly were substantially less likely to die – especially from cardiovascular disease – over the following decade. The study tracked those 4,282 people for an average of about 12 years.
The test has a name – the sitting-rising test, or SRT – and a 10-point scoring system. Points are deducted each time you need to use a hand, forearm, knee, or the side of your leg for support, and for visible instability. Most people assume they’ll score reasonably well. Many don’t.
A blood pressure reading tells you about one variable. A cholesterol panel tells you about lipids. These movement-based longevity functional tests capture something more integrated: how well your entire system – muscles, joints, balance mechanisms, motor control, and body composition – works together under real-world conditions. For anyone over 75, that integrated picture may be more informative than almost any lab value their doctor orders.
The Sitting-Rising Test: What the 2025 Data Shows
Non-aerobic physical fitness, as assessed by the SRT, proved to be a significant predictor of natural and cardiovascular mortality in adults between 46 and 75 years old. The mortality differences across score groups were stark.
The study was authored by Dr. Claudio Gil S. Araújo, Dean of Research and Education at Clinimex, and colleagues, published in the European Journal of Preventive Cardiology in 2025. Participants were divided into five performance groups based on their composite scores. The sitting-rising test measures several key components of non-aerobic fitness at once – muscle strength and power, flexibility, balance, and body composition – without requiring any equipment.
Death rates ranged from 3.7% in the highest-scoring group down to 42.1% in the lowest-scoring group – a more than tenfold difference between people who could complete the movement cleanly and those who couldn’t. Adults in the top scoring category were six times less likely to die from cardiovascular disease and four times less likely to die from any cause compared to those at the bottom.
Each incremental improvement on the 10-point scale carried real survival weight. The study added to a growing body of evidence showing that various measures of physical function beyond aerobic fitness – including flexibility, the ability to stand on one leg, and grip strength – can predict longevity. Research on the SRT’s scoring structure has found each point improvement correlated with a 21% survival gain.
Dr. Prashant Rao, a cardiologist at Beth Israel Deaconess Medical Center, commenting on the findings, said the study highlights the importance of functional measurements in cardiovascular health assessment. “I think physicians intuitively know that certain patients would do poorly on this test, but to show that this type of poor functioning is clearly linked to future survival is an important contribution,” he said.
One important practical note: there is no meaningful sex difference in SRT scores because while men may have more raw strength, women compensate with greater flexibility. The total score evens out, making the test a genuinely generalizable clinical tool.
How to Perform the SRT
Stand on a bare floor in comfortable clothing. Without using any furniture or walls for support, lower yourself to sit cross-legged on the floor. Then rise back to standing. To score a perfect 10, you must complete both movements – the lowering and the rising – without using your hands, forearms, knees, or the sides of your legs for support, and you must remain steady throughout. Each support touch or loss of balance costs half a point. A score below 8 out of 10 suggests meaningful gaps in the physical capacity domains the test is measuring. A score of 3 or below puts someone in the highest-mortality group from the 2025 research.
Walking Speed: The Vital Sign Most Clinics Don’t Track
The sitting-rising test isn’t the only functional check with this level of predictive power. Gait speed – the pace at which a person walks normally – has quietly accumulated one of the strongest evidence bases in geriatric medicine.
A landmark 2011 meta-analysis led by Dr. Stephanie Studenski of the University of Pittsburgh, published in JAMA, pooled data from 34,485 community-dwelling older adults across nine studies and found that gait speed was associated with survival at every age studied. The findings were precise down to fractions of a meter per second. A walking speed of approximately 0.8 meters per second – about 1.8 miles per hour – was associated with the predicted median life expectancy for a given age and sex. Gait speeds of 1.2 meters per second and faster predicted “exceptional” life expectancy, the investigators reported.
After age 75, gait speed becomes particularly revealing. At age 75, predicted 10-year survival across the full range of gait speeds ranged from 19% to 87% in men and from 35% to 91% in women – a spread that dwarfs most clinical risk tools used in routine medicine. The same walking pace that puts a 75-year-old in the top survival tier would, for a slower-walking peer, suggest a 10-year survival probability below one in five.
Gait speed decline matters as much as gait speed itself. Of 2,364 participants aged 70 to 79 in the Health, Aging and Body Composition Study, researchers identified three gait speed decline trajectories. Those with the fastest decline lost 2.4% of walking speed per year from baseline. Participants with fast decline carried a 90% greater risk of mortality than those with slow decline, according to a 2013 study in the Journals of Gerontology.
A 6-meter walk measured with a stopwatch at home or in a clinic is sufficient. If a person over 65 is walking below 0.8 m/s, that’s a signal worth discussing with a physician – not as a diagnosis, but as a prompt for further assessment.
Handgrip Strength: Stronger Than Blood Pressure for Predicting Death
Most adults over 50 have had their blood pressure measured hundreds of times. Far fewer have had their grip strength tested. The research increasingly suggests grip strength deserves to be taken just as seriously – or more so.
A 2025 systematic review found that handgrip strength was a more powerful indicator of mortality and cardiovascular mortality than systolic blood pressure in older adults. The dose-response relationship is consistent: for each 5-kilogram reduction in handgrip strength, the hazard ratio for all-cause death increases by 16%, according to the same 2025 review.
Among community-dwelling older adults aged 65 and above, poor handgrip strength was associated with an adjusted hazard ratio of 1.87 for increased mortality, according to a 2023 study – meaning those with weak grip faced nearly twice the death risk of those with adequate grip after accounting for other health variables.
Grip strength is a proxy for overall skeletal muscle integrity. Muscle tissue is metabolically active; it regulates blood sugar, supports cardiovascular function, and protects against the physical frailty that accelerates mortality in older adults. A dynamometer squeeze – a handheld device that measures force in kilograms – takes under 30 seconds and requires no physician training to administer. For adults over 65, the rough threshold worth flagging is below 27 kg for men and below 16 kg for women, per the European Working Group on Sarcopenia in Older People (EWGSOP2) guidelines.
The Timed Up and Go Test: Mobility Under Time Pressure
The Timed Up and Go test, or TUG, is routinely used in geriatric clinics and fall-risk assessments. The protocol is direct: start seated in a standard chair, stand up, walk three meters at your normal pace, turn around, walk back, and sit down again. The clinician times the full sequence.
A 2022 meta-analysis found that TUG test performance was associated with all-cause mortality risk, with each additional second of completion time corresponding to a 5% increase in hazard ratio for death, according to research published in BMC Geriatrics. For reference, healthy adults in their early 60s typically complete the TUG in under 10 seconds. Times above 12 seconds in adults over 65 are a common clinical threshold for elevated fall risk; times above 20 seconds suggest significant mobility impairment.
Falls are the leading cause of injury-related death in persons aged 65 and older, and more than 25% of older adults fall each year, according to a 2025 review. The TUG test provides a fast, equipment-free way to flag individuals at highest risk before a fall occurs. Exercise-based interventions reduce fall rates by 23% in older adults, with participants in structured programs showing a relative risk of 0.77 compared to non-exercising controls – a meaningful reduction achievable without pharmaceuticals.
The Short Physical Performance Battery and Intrinsic Capacity
For more comprehensive clinical assessment, the Short Physical Performance Battery (SPPB) combines three components: a standing balance test (feet together, semi-tandem, and tandem positions), a 4-meter gait speed test, and a five-repetition chair-stand test. The resulting score runs from 0 to 12. An SPPB score lower than 10 is predictive of all-cause mortality in older adults, according to a study in BMC Medicine.
The SPPB matters because it combines several of the domains that individual tests measure separately. This points toward the broader concept of intrinsic capacity – a framework the World Health Organization uses to assess healthy aging. Intrinsic capacity is the composite of all physical and mental capacities an individual can draw on, organized across five domains: locomotion, cognition, vitality, sensory, and psychology.
Research published in 2025 found that intrinsic capacity proved superior to frailty measures in predicting dementia over 10 years and mortality over 12 years, according to findings in the International Journal of Geriatric Psychiatry. The predictive precision is striking: logistic regression analysis found intrinsic capacity to be a strong predictor of healthy longevity, with an area under the ROC curve of 0.97 – a value close to perfect discrimination – according to a 2024 study in PLOS ONE. Each 1-point improvement in intrinsic capacity score has been associated with a 5% decrease in mortality odds among older adults, according to a 2023 scoping review.

Study Limitations Worth Noting
The sitting-rising test research, though robust, carries important caveats. The 4,282 participants were volunteers who came in for medical evaluations focusing on physical fitness and health, and none presented relevant physical or clinical limitations for fitness testing. That self-selection means the sample was likely healthier and more motivated than the general population, which could affect how broadly the mortality statistics apply.
The gait speed literature draws on observational cohort studies – they demonstrate strong associations, but cannot prove that increasing walking speed directly extends life. Physical function and mortality share many common causes (chronic disease, nutritional status, inflammation), and disentangling them fully remains difficult.
The handgrip strength and TUG data are similarly observational. No randomized controlled trial can ethically assign people to low or high grip strength and track mortality over a decade. What the evidence does support confidently is this: these tests identify people at elevated risk with a degree of accuracy that matches or exceeds conventional clinical markers, and they do so without needles, imaging, or specialist equipment.
Key Takeaways
No single assessment captures the full picture, but the convergence across four different longevity functional tests – the sitting-rising test, gait speed, handgrip strength, and the Timed Up and Go – points to a consistent underlying signal: the quality of physical function predicts survival more precisely than many physicians and patients realize.
For adults over 65, three practical steps follow directly from this evidence. First, ask your doctor to measure gait speed at your next appointment – a 4-meter walk takes under a minute. If your pace is below 0.8 m/s, that’s a conversation worth having about exercise, nutrition, and further evaluation. Second, test your grip strength. Many physiotherapy clinics have a dynamometer; the test itself takes 20 seconds per hand. Third, try the sitting-rising test at home on a carpeted surface, ideally with someone nearby the first time. A score below 8 out of 10 suggests real gaps in strength, flexibility, or balance worth addressing through structured exercise.
Exercise-based interventions improve performance on every one of these assessments. Resistance training, balance work, and walking programs – particularly when tailored to an individual’s current function level – have demonstrated measurable effects on gait speed, grip strength, and mobility over timescales of 12 to 24 weeks. The biological targets are tangible, the interventions are low-cost, and the evidence connecting improvement on these tests to survival is stronger than it has ever been. For anyone asking how long they’re likely to live after 75, the most honest answer available right now starts with: get up off the floor and see how you do.
