Leg balance is a key indicator of healthy aging

Struggling with the bathroom scale or sighing into the mirror doesn’t expose the hidden secrets of aging. What if standing on one leg to test your balance is a more accurate gauge of aging than changes in strength or walking style?

Balance, muscle strength, and gait are essential to independence and well-being as people age. Improving leg balance is crucial in maintaining these aspects.

Scientists studied how these factors change and at what pace to develop effective programs for healthy aging. The good news? People can train their balance without special equipment and maintain it over time.

Balancing on one leg

40 spry, independent individuals over 50 were central figures in a study measuring their walking ability, balance, grip strength, and knee strength.

They braced themselves on force plates under various situations. This included standing on both feet with eyes open and closed, and standing on their non-dominant and dominant leg with eyes open.

The most significant revelation? Standing on the non-dominant leg showed the highest rate of decline with age, highlighting the importance of consistent leg balance exercises.

The science behind the balance

“Balance is an important measure because, in addition to muscle strength, it requires input from vision, the vestibular system and the somatosensory systems,” says Kenton Kaufman, Ph.D., senior author of the study and director of the Motion Analysis Laboratory at Mayo Clinic. “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.”

Other aspects of aging

In addition to balance, the study measured participants’ grip and knee strength using custom-made devices.

Both showed significant declines by decade, but not as much as balance. Grip strength decreased faster than knee strength making it another potent predictor of aging.

Gait parameters didn’t change with age, and there were no substantial age-related declines in strength tests tied to gender. This suggests age impacted male and female subjects alike.

Practical implications

Understanding the nuances of the research has implications for everyday practice including those endeavoring to sustain functional independence as they age. Maintaining good leg balance significantly helps.

Engaging in exercises that enhance balance seamlessly incorporate into daily routines without requiring complex equipment or specialized training environments.

Simple practices such as standing on one leg while brushing teeth or incorporating tai chi and yoga into weekly activities positively influence balance and reduce the risk of falls.

Emphasizing balance-enhancing activities is the cornerstone of a robust approach to aging healthily, aligning with the study’s insights into maintaining physical autonomy.

Future directions

The study’s findings signal new horizons in gerontological research, highlighting the necessity to explore the multifaceted nature of aging including leg balance.

Future studies will delve deeper into the interplay between neural feedback and physical performance over time. They could consider psychological and lifestyle factors that might mitigate or accelerate age-related declines in balance and strength.

Longitudinal studies involving diverse populations help craft personalized intervention programs tailored to individual strengths and limitations.

By advancing the understanding of these dynamics, researchers better equip societies with the tools to support aging communities to maintain their quality of life and well-being.

How long should we balance on one leg?

So, where do researchers go from here? Dr. Kaufman believes people can take steps to train their balance such as standing on one leg.

Coordinating the muscle responses required for leg balance helps maintain overall stability. If a person can stand on one leg for 30 seconds, they’re doing well.

“If you don’t use it, you lose it. If you use it, you maintain it,” Kaufman said. “It’s easy to do. It doesn’t require special equipment, and you can do it every day.”

As people age, staying active becomes more crucial, and this research highlights the importance of balance in daily routines.

Balance isn’t just about standing up straight. It’s about embracing a healthier, more dynamic way of aging.

The study is published in the journal PLoS ONE.
