Olympic Medalist Yarden Gerbi Shares Viral Balance Test for Biological Age

Olympic medalist and judoka Yarden Gerbi recently shared a simple balance test on her Instagram account that she claims can indicate the biological age of the body. The test requires participants to cross their arms over their chests in an X shape, lift one foot off the ground, and close their eyes. The duration a person can maintain this position allegedly reflects their physical age: five seconds corresponds to age 65, ten seconds to 55, fifteen seconds to 45, twenty seconds to 35, twenty-five seconds to 30, and over thirty seconds indicates an age under 30.

The Gap Between Chronological and Biological Age

Behind the test, Gerbi notes, lies a broader question regarding the difference between the age listed on an identity card and the actual physical age of the body. While chronological age merely counts the years since birth, physical condition is heavily influenced by lifestyle and how well an individual cares for their body over time.

"No single test or smartwatch can truly determine our precise biological age, but balance is a key indicator of things we can actively improve," Gerbi emphasized.

Scientific Backing and Balance Training

Research supports the connection between balance and aging processes. A large-scale study published in the British Journal of Sports Medicine tracked older adults over a seven-year period. Researchers found that individuals who could not stand on one leg for 10 seconds faced an 84% higher risk of all-cause mortality during the follow-up period compared to those who could.

Another study conducted by the Mayo Clinic highlighted that a decline in one-legged balance is a more sensitive indicator of biological aging than changes in grip strength or walking speed. Experts note that balance can be improved at any age through simple daily exercises, such as standing on one leg while brushing teeth or cooking, provided safety precautions are taken to prevent falls.
