Thirty seconds, one chair: a simple stand-up test flags who needs help earliest

No scanner, no blood draw — just a chair and half a minute. In Spain's Toledo Study for Healthy Aging, researchers followed 1,876 adults aged 65 and over and used the 30-second sit-to-stand test: how many times you can rise from a chair in 30 seconds, a plain measure of lower-body muscle power. People with low power fared markedly worse over the following years — men had about 73% higher odds of falls, women were more than three times as likely to have suffered a hip fracture, and both sexes faced longer hospital stays and roughly double the risk of death for women. Published in the Journal of Sport and Health Science, the finding turns an everyday movement into an early-warning system: because the test is free and takes 30 seconds, clinics — or families — can spot who would benefit earliest from strength training, physiotherapy or fall-prevention help, long before a crisis.
