The Surprising Power of Standing on One Leg: What Balance Reveals About Aging
A simple balance test can reveal neuromuscular changes and highlight early fall risks.
Why Standing on One Leg Reveals So Much About Healthy Aging
Most people think of aging as a slow decline in energy, strength, or memory, but researchers are finding that balance may be one of the most important keys to predicting how well someone will age. A recent study published in PLOS ONE and led by Mayo Clinic researchers has drawn attention to the single leg stance test — a simple measurement that reveals crucial insights into neuromuscular health. The findings suggest that your ability to balance on one leg may be a stronger indicator of aging than grip strength, walking speed, or muscle power.
Understanding the Single Leg Stance Test
The single leg stance test, also called the unipedal stance test, is easy to perform and requires no special equipment. Here’s how it works:
- Stand barefoot with both feet flat on the floor, arms at your sides.
- Lift one foot — usually the non-dominant leg — and try to balance for up to 30 seconds.
- Repeat on the other side.
If needed, rest for 10 seconds between attempts. The researchers recommend repeating the test 6–8 times on each leg to get accurate measurements. You can make the test more challenging by closing your eyes or moving the lifted leg into different positions.
What Does the Single Leg Stance Actually Measure?
Although it looks simple, balancing on one leg is a complex task that requires the harmonious coordination of several bodily systems:
- Muscles: Stabilize the joints and maintain posture.
- Nerves: Relays signals from muscles to the brain.
- Inner Ear (Vestibular System): Senses changes in head position and helps with orientation.
- Eyes (Vision): Provides spatial information to guide subtle adjustments.
- Somatosensory System: Feeds information from skin, joints, and tendons to the brain.
“Balance is complicated. It involves your vision, your vestibular system, your somatosensory system, and your neuromuscular system. All those have to work in coordinated fashion to keep you on one leg,” explains Dr. Kenton Kaufman, the Mayo Clinic study’s senior author.
The Study: What Researchers Discovered About Balance and Aging
The Mayo Clinic study involved 40 healthy, independent adults over the age of 50. Half of the subjects were younger than 65, and half were older. Each participant completed a battery of tests measuring walking speed, grip strength, knee strength, and balance, including multiple variations of the single leg stance:
- Standing on both feet with eyes open
- Standing on both feet with eyes closed
- Standing on the non-dominant leg with eyes open
- Standing on the dominant leg with eyes open
Each test lasted up to 30 seconds, and participants could hold their lifted leg in any comfortable position. The main findings:
What others are reading
- Older adults generally could not hold the one-leg stance as long as younger adults.
- The duration a person could hold a single leg stance was the most reliable predictor of age-related decline — more so than grip strength, knee strength, or gait speed.
- The ability to stand on one leg declined fastest on the non-dominant leg.
In other words, how long you can stand on one leg offers important clues about the health of your entire neuromuscular system and may reflect how well you are aging compared to your peers.
Why Balance Declines With Age
Maintaining good balance requires real-time feedback from several systems — and unfortunately, all of these systems deteriorate with age, though not at the same rate:
- Vision declines as the eyes become slower to focus and perceive movement.
- Vestibular function in the inner ear can degrade, making orientation harder.
- Muscle strength and power naturally wane.
- Sensory nerves lose responsiveness, which means slower adjustments.
This slower integration makes it harder to stay balanced, increasing the risk of losing independence or suffering falls — which are a leading cause of injury and accidental death among older adults.
How Balance Tests Predict Independence and Risk
Why is it useful to know how long you can balance on one leg? The answer is simple but profound. Loss of balance is tied directly to:
- Risk of falling, which can lead to fractures, loss of independence, and hospitalization.
- Overall neuromuscular health, a major contributor to the ability to perform daily tasks alone.
- Early warning signs of decline, giving you a chance to intervene.
If a person can balance for 30 seconds on one leg, that’s considered excellent for someone over 50. Failing to maintain balance for at least five seconds is a red flag indicating a higher risk for falls and may signal the need for more targeted interventions.
Does Balance Begin to Decline Early?
The research is clear: Neuromuscular aging measured by balance doesn’t typically appear until people are in their 50s. If you struggle to balance at an earlier age, don’t panic — early difficulties aren’t direct indicators of subsequent aging. However, if you’re over 50 and outperform your peers in balance, it’s a sign your neuromuscular health is solid and may help you maintain independence.
Can You Train Balance and Slow Neuromuscular Aging?
The best news? It is never too late to improve your balance. Regular practice can train your body to integrate feedback from all the systems involved, helping you maintain healthy movement and reduce the risk of falls.
How to Improve Balance at Home
- Practice the single leg stance for up to 30 seconds per side, rest for 10 seconds, and repeat 6–8 times.
- Make it harder by closing your eyes or moving the lifted leg outward.
- Include other balance exercises, like heel-to-toe walking, standing yoga poses, or Tai Chi.
- Strengthen lower body muscles with squats, lunges, and calf raises.
- Challenge proprioception — your sense of position — by standing on softer surfaces or wobble boards.
Balance training benefits people of all ages but is especially vital after 50, when the risk of falls rises sharply.
Why Balance Matters: Risks and Rewards
Having good balance isn’t just about avoiding accidents — it’s about sustaining the freedom to move through life with confidence.
- Independence: Better balance allows older adults to live on their own for longer, reducing dependence on caregivers.
- Activity: Improved balance means you’re more likely to stay active, travel, and participate in hobbies.
- Health: Avoiding falls lowers risk of broken bones and long hospital stays.
- Brain Health: Balance exercises are surprisingly good for stimulating memory and cognitive function.
Falling can be devastating, but with regular balance training and awareness, many falls are preventable.
How Does Balance Compare to Other Aging Measures?
| Measure | Predicts Aging | Involvement of Body Systems | Linked to Fall Risk |
|---|---|---|---|
| Single Leg Balance | Very Strong | Muscles, nerves, vision, vestibular, sensory | Direct |
| Grip Strength | Moderate | Muscles, nerves | Indirect |
| Knee Strength | Moderate | Muscles | Indirect |
| Walking Speed (Gait) | Somewhat Strong | Muscles, nerves, coordination | Indirect |
The table above highlights why balance — especially the single leg stance — emerges as the most reliable and sensitive marker of neuromuscular aging.
Who Should Try the Balance Test?
The test is particularly useful for adults over 50, regardless of current physical activity levels. It’s also valuable for clinicians looking to:
- Identify patients at higher risk of falls.
- Track age-related changes for personalized care plans.
- Motivate patients to continue healthy movement and balance training.
If you or someone you care for is worried about falling, this simple measurement can provide valuable insight and help guide next steps.
Frequently Asked Questions (FAQs)
Is the single leg stance test safe for everyone?
Most healthy adults can safely perform the test. If you have any history of falls, dizziness, or mobility issues, consult a healthcare provider first and try near a stable surface or with support nearby.
How long should a healthy adult over 50 be able to balance on one leg?
Ideally, 30 seconds is considered excellent. Unable to maintain balance for at least five seconds may indicate an increased fall risk and a need for improvement.
Does practicing the test directly improve balance?
Yes. Regular practice activates muscles, nerves, and feedback systems, making your balance sharper over time.
Is balance loss inevitable as we age?
Some decline is natural, but proactive training and awareness can slow or reverse some losses, helping you maintain independence longer.
Are balance exercises as important as strength or cardio?
Absolutely. Cardiovascular and strength training are vital for overall health, but balance training is unique in preventing falls and promoting safe movement, especially in older adults.
The Bottom Line: Small Test, Big Insights
Standing on one leg for 30 seconds might seem trivial, but it offers profound clues about your body’s ability to age well. By regularly practicing balance and paying attention to how long you can maintain the stance — especially after age 50 — you empower yourself to take charge of neuromuscular health, reduce the risk of falls, and embrace a more active, independent future. Clinicians are taking note, and now, so can you.
Tips to Integrate Balance Training Into Your Routine
