Why balancing on one leg matters as we age
Standing on a single leg for even a few seconds may reveal critical insights about overall health, muscle loss, and cognitive function in older adults. While effortless in youth, this simple act becomes increasingly difficult after age 50-and researchers say targeted training can mitigate risks.
The science behind single-leg stability
Human balance peaks in the late 30s before gradually declining, according to rehabilitation specialists. By midlife, the ability to hold a one-legged stance correlates with muscle mass retention, a key factor in preventing sarcopenia-the age-related loss of muscle tissue. Studies show muscle mass decreases by up to 8% per decade after 30, with half of octogenarians experiencing clinical sarcopenia.
Kenton Kaufman, director of the Mayo Clinic's Motion Analysis Laboratory, notes that balance deterioration accelerates after 60. "People notice it in their 50s or 60s, and it worsens with each passing decade," he said.
Brain health and fall prevention
Balancing on one leg engages multiple sensory systems: vision, the inner ear's vestibular system, and the somatosensory network, which processes body position and ground contact. Age-related degradation in these systems impairs reaction times, increasing fall risks-a leading cause of injury among U.S. adults over 65, per CDC data.
A 2022 study found that midlife adults unable to hold a one-legged stance for 10 seconds faced an 84% higher risk of premature death over seven years. Another study tracking 2,760 participants in their 50s linked poor single-leg balance (under two seconds) to triple the mortality risk over 13 years compared to those who held the pose for 10+ seconds.
"If you can't stand on one leg for five seconds, it often predicts faster cognitive decline in Alzheimer's patients,"

How to train for better balance
Experts recommend integrating single-leg exercises into daily routines, such as brushing teeth or washing dishes. Claudio Gil Araújo, an exercise medicine researcher, suggests alternating legs for 10-second intervals, both barefoot and in shoes, to improve stability.
"Just 10 minutes of daily practice can yield measurable gains," Araújo said. He also highlights the benefits of isokinetic exercises (gentle resistance training) and activities like yoga or tai chi, which reduce fall risks by 19% and 50%, respectively, when combined with strength training.
Lifelong benefits and real-world success
Neuroplasticity allows the brain to adapt to balance training at any age. Tracy Espiritu McKay emphasizes that such exercises enhance sensory-motor integration and spatial awareness, even improving working memory in young adults.
Araújo's clinic documented a 95-year-old woman who maintained a 10-second single-leg stance on either foot, proving that consistent training can preserve function well into advanced age. "We can improve biological systems until life's final days," he said.
Key takeaways
- Adults over 50 should self-assess their single-leg balance; inability to hold for 10 seconds may signal health risks.
- Daily practice (e.g., while brushing teeth) strengthens muscles and cognitive function.
- Tai chi and yoga offer additional balance benefits, reducing fall risks by up to 50%.
