Sometimes I hate learning things.
This is one of those times.
For weeks now, news outlets everywhere are all writing about some recent research that shows that poor performance on a 10-second one-legged balance test predicts higher mortality in middle-aged test subjects.
If you recklessly claim that a single variable leads to death, you can make the news. (Fear gets people to read so editors can’t resist.) If you recklessly claim that a single variable leads to health or less chance of death, you would get widely criticized for it.
For example, if I used this same study to claim that performing well on a single leg stand test for 11 seconds or longer decreases mortality risk, I would – somewhat justifiably – be criticized for spreading misinformation.
Balance is one of many measures of fitness. If a large study group (they used 1700 people in the study discussed here) performs poorly on any one single measure of fitness, for sure there will be higher mortality among less fit people in general. It is another thing to conclude that this specific test has some magical bearing on mortality.
You might recall that a similar news splash happened not too long ago with grip strength.Poor grip strength was correlated with higher mortality. Duh.Again – poor fitness is correlated with higher mortality.
If I work on my grip strength and balance, I’ll be invincible!
At least the study authors used a low enough threshold of 10 seconds.Most balance tests are horribly flawed in design and have you stand on one leg for 30 seconds with your eyes closed – something you would never need to do in real life (unless someone is running you through this silly test.)
In life, we most often have our eyes open and we are moving, even if on a single leg.And these movements are often done in response to something in the outside world – something we want to pick up, put down, go after, or move away from.It makes sense then to (1) train balance in realistic ways and (2) to integrate reactive training with balance training.
I provide examples of how to do this usefully, practically, and realistically in the Alzheimer’s Fitness Specialist Course – 40% off through July 5 with code JULY4.
