A new study suggests that a simple and easy-to-perform test, requiring no special equipment, may help estimate a person’s life expectancy.

Researchers from the Exercise Medicine Clinic in Rio de Janeiro have found that a sit-to-stand or stand-to-sit test can serve as a powerful indicator of overall health and longevity in middle-aged and older adults. Their findings were published in the European Journal of Preventive Cardiology.

The test, which evaluates balance, muscle strength, and flexibility, requires individuals to sit down on the floor and stand back up without using their hands, arms, or knees for support.

According to the researchers, this basic movement provides insight into non-aerobic fitness and may uncover potential health problems that are not always detected through standard clinical assessments.

To conduct the study, the Brazilian research team recruited 4,282 adults — predominantly men — between the ages of 46 and 75. Each participant underwent a health assessment before performing the sit-rising test. Researchers then followed up with the participants over a 12-year period.

The results were striking: participants who achieved the highest scores on the test were significantly more likely to be alive at the end of the follow-up period. Conversely, those who scored the lowest or were unable to complete the test properly were more likely to die earlier, often due to medical complications.

Lead researchers noted that while the test is not meant to replace comprehensive health screenings, it could be a useful, quick tool to highlight underlying fitness issues and prompt further investigation.

Experts believe the simplicity and accessibility of the test could make it a valuable tool for physicians and individuals alike, particularly in resource-limited settings.
