The ability to stand on one leg has emerged as one of the best indicators of long-term health.
Mayo Clinic researchers say leg balance is a better “telltale sign” of aging than a person’s strength or gait.
“Good balance, muscle strength and an efficient gait contribute to people’s independence and well-being as they age,” the research report said.
“How these factors change, and at what rate, can help clinicians develop programs to ensure healthy aging. Individually, people can train their balance without special equipment and work on maintaining it over time.”
The study involved 40 healthy, independent people aged over 50 who underwent walking, balance, grip strength and knee strength tests.
Standing on one leg showed the highest rate of decline with age.
“Balance is an important measure because, in addition to muscle strength, it requires input from vision, the vestibular system and the somatosensory systems,” study author Kenton Kaufman said.
“Changes in balance are noteworthy. If you have poor balance, you’re at risk of falling, whether or not you’re moving. Falls are a severe health risk with serious consequences.”
The research report said unintentional falls were the leading cause of injuries among adults aged 65 and older.
Dr Kaufman says people could train themselves for better balance, including practicing standing on one leg for 30 seconds.
“If you don’t use it, you lose it. If you use it, you maintain it,” Dr. Kaufman said. “It’s easy to do. It doesn’t require special equipment, and you can do it every day.”
