Even strong athletes wobble when the eyes close

Balance is not strength. I find myself saying that often to the people I work with, and it still tends to surprise them, because we picture steadiness as something the legs hold us in. A study out this month makes the point more plainly than I can. It took competitive weightlifters, among the strongest and most coordinated movers in their age group, and found that their steadiness wavered the moment it took away their eyes.

The research, an observational study in BMC Sports Science, Medicine and Rehabilitation, tested 104 Masters weightlifters from eleven countries, ranging in age from 35 to 75. Each stood through four balance conditions: a firm surface with eyes open, a firm surface with eyes closed, a foam surface with eyes open, and a foam surface with eyes closed. On firm ground with the eyes open, sway stayed low, as you would expect from strong, well coordinated athletes. On the foam it grew. With the eyes closed it grew more. And when the researchers looked at what actually predicted these athletes' competition results, it was peak power, the raw explosive strength weightlifting is built on, that did the work. Postural stability added only a modest amount (BMC Sports Sci Med Rehabil, 2026).

These are among the strongest, most practiced movers in their age group, and even they wobbled once the floor stopped giving reliable feedback and the eyes were shut. That tells you something about what balance really is. It is not a muscle you can force into steadiness. It is the nervous system quietly stitching together several streams of information at once: pressure and stretch from the feet and joints, the horizon from the eyes, the sense of head position from the inner ear. Take one stream away, or make it unreliable, and you find out how good the stitching is.

This is where the study reaches well past a competition hall. The same stitching that the foam and the closed eyes exposed in these athletes is the stitching that tends to fray as we age. The signal from the feet grows fainter, reactions lengthen, and the margin for a stumble narrows. It matters because falls are not a minor footnote to aging. The World Health Organization notes that among older people who do fall, 20 to 30 percent suffer moderate to severe injuries such as bruises, hip fractures, or head trauma (WHO, 2021). You can read more about how that sensing quietly changes over the years in our Feldypedia entry on proprioception decline with age.

The tempting takeaway is more strength work, and strength certainly has its place. But the study is pointing at something strength did not fix in the athletes themselves. What refines balance is attention to the sensing, not gritting your way through wobble. This is the ground the Feldenkrais Method® has always worked on. In an Awareness Through Movement® lesson, steadiness is not drilled by standing on one leg until you shake. It is grown by noticing, in fine detail, how the weight moves through the feet, how the eyes and the head are involved, how much bracing is actually necessary and how much can quietly drop away.

Here is a short experiment that borrows the study's own trick. It takes a sense away on purpose, so the others have to wake up. Do it near a counter or a wall, and only go where it feels easy, pleasant, and comfortable.

Notice that closing the eyes was never a test to pass. It was a way to feel your own sensing system come online. That is the whole point. Balance grows the way most skills grow, through the nervous system getting more practice at sensing and adjusting, in small and pleasant doses rather than one heroic effort. This kind of practice sits alongside anything a physiotherapist has given you for steadiness rather than replacing it, and if your balance feels genuinely unreliable, that is worth raising with a doctor or physiotherapist first. Tai chi, which so many older adults find steadying, works on some of the same sensing through a different mechanism, gentle and slow in its own way; each approach has its own strengths.

What makes this study worth your attention is not the athletes at all, but the flip side it points to. Even these powerful weightlifters grew less steady once their sensing was challenged, which means steadiness was never only a matter of the legs. And sensing, unlike raw power, stays trainable at any age, quietly, with attention. You have not lost your balance so much as lost some contact with the information that keeps you upright. A few minutes of listening to your own feet is a small way to start getting it back, and you can read more about the fear that unsteadiness can breed, and how movement can ease it, in our entry on balance, instability, and the fear of falling.
