Simple Sit Test May Predict Your Risk of Death

Could a seemingly simple movement reveal crucial insights about your future health? According to a significant study, the ability to smoothly move from a standing to a sitting position on the floor and back again, without support, may offer a surprising prediction about your risk of death in the next decade or so.

This assessment, known variously as the “Sit-and-Rise Test (SRT),” “Sit-to-Stand Test,” or “Cross-Leg Get-Up Test,” measures more than just flexibility. It’s a powerful indicator of integrated physical fitness, evaluating your balance, muscular strength, coordination, and even providing clues about body composition relative to your strength.

The Study Behind the Sit Test Prediction

Research published in the European Journal of Preventive Cardiology analyzed data from 4,282 men and women in Brazil, aged 46 to 75. Led by Dr. Claudio Gil Araujo from the Clinimex sports medicine clinic in Rio de Janeiro, the study followed participants for up to 25 years, with mortality data specifically tracked over a 12-year period. Participants with pre-existing hip, spine, or knee problems were excluded to ensure the test’s suitability.

How the Sit-to-Stand Test Works

Performing the Sit-to-Stand test requires no equipment, but it does demand controlled movement:

Start Standing: Stand barefoot with your feet slightly apart.
Cross Legs: Cross one foot in front of the other.
Lower Down: Without using your hands or changing your foot position for support, slowly lower your body to a cross-legged sitting position on the floor.
Stand Up: From the sitting position, stand back up, ideally without touching the floor with your hands or using other supports.

It’s recommended to try this test on a soft surface like a rug and have a sturdy object nearby for safety in case you lose balance. However, do not attempt this test if you have any existing joint issues (knees, hips, back) or physical disabilities that would make it unsafe.

Scoring Your Performance

The test is scored out of a maximum of 10 points. Five points are awarded for the sitting phase and five for the standing phase. Points are deducted for using support:
Subtract 1 point each time you touch the floor with your hand, knee, or use any other external support during the descent or ascent.
Subtract 0.5 points if your body shakes or loses balance during the movement.

A perfect score of 10 means you performed the test flawlessly without any support or instability.

What Your Sit Test Score Could Mean for Your Longevity

The study found a striking correlation between test scores and mortality risk over the 12-year follow-up:

Low Scores (0 to 4): Participants in this group had a mortality rate of 29.7%, which was more than 10 times higher than those who scored perfectly. Some analyses indicate this group could be up to six times more likely to die from various causes compared to high scorers.
High Scores (8 or Higher): Individuals scoring 8 or above demonstrated a particularly low mortality rate within the 12-year period.

Near-Perfect Scores (8.5 to 9.5): This group had more than double the probability of survival compared to their probability of death over 12 years.

Dr. Araujo noted that the test’s ability to assess muscle health, balance, and flexibility makes it a valuable predictor of future longevity, particularly for middle-aged adults.

Beyond the Sit Test: The Broader Link Between Physical Function and Longevity

Dr. Araujo’s team has also explored the link between other measures of physical function and mortality. Their research on overall body flexibility, assessed using a comprehensive “Flexindex” score, also found that higher flexibility in middle age was associated with a lower risk of death over a 13-year period. Similarly, the simple act of standing on one leg for 10 seconds has also been linked to survival rates in their prior work.

These studies reinforce the idea that maintaining functional fitness – encompassing strength, balance, flexibility, and coordination – as you age is crucial not only for quality of life and preventing falls but potentially also as an indicator of broader health and longevity. While the observational nature of these studies means they show association, not direct cause, and experts point out that tests like these might reflect overall healthy habits rather than flexibility or sit-test ability being direct drivers of survival, they serve as a powerful, accessible snapshot of your current physical capabilities.

The Sit-to-Stand Test offers a simple, self-administered way to gauge your functional fitness level. While it’s not the sole determinant of your lifespan, your score can serve as a valuable prompt to consider improving your strength, balance, and flexibility for better long-term health prospects.
