The reason this humble test made headlines at all is a line of research connecting it to longevity. In the original 2012 study, researchers followed 2,002 adults aged 51 to 80 for about six years. Those who scored in the lowest range (0 to 3) were roughly five to six times more likely to die during the study than those scoring 8 to 10, and each one-point bump in score was associated with about a 21% lower risk of death over that period.
A much larger follow-up extended the picture. As a plain-language summary of the 2025 study lays out, researchers tracked 4,282 adults aged 46 to 75 for an average of more than 12 years. Deaths climbed steadily as scores fell: about 3.7% among those who scored a perfect 10, rising to 11.1% at a score of 8, and reaching 42.1% in the lowest-scoring group. After accounting for other factors, the lowest scorers had roughly a 3.8-fold higher risk of death from natural causes and about a six-fold higher risk of cardiovascular death than those who scored 10, with estimated 10-year survival of about 97% for a perfect score versus 73% for the lowest group.
Those numbers are striking, and they are also where careful reading matters most. Both studies are observational, which means they show an association, not proof that a low score causes an earlier death—or that your personal number predicts your personal lifespan. The research looked at specific middle-aged and older groups, and the tests were supervised. The test's developer has been clear that the SRT is meant to work as a screening signal that nudges a clinician to look more closely at someone's overall risk, not as a verdict to take to heart on a Tuesday afternoon. A low score is best thought of as a yellow flag worth a conversation, not a sentence.
Why the Connection Might Exist
If you are wondering why a floor movement would track with long-term health at all, the leading explanation is intuitive. The strength, flexibility, and balance the test captures are the same abilities that let people stay active, care for themselves, and avoid falls as they age—and those, in turn, are woven into cardiovascular and overall health. The test does not work magic; it simply reflects a cluster of functional abilities that tend to travel together with staying well.
