I think what GP is saying is that this test correlates with things like 'fitness' and 'balance', which themselves are causally related to health outcomes. But training to balance on one leg doesn't mean that your 'balance' or 'fitness' overall improve. It might be that one legged balance doesn't improve 'balance' and so doesn't improve your health outcomes. Or 'balance' is irrelevant, and it's just that 'fitness' means you're less winded at the top of the steps, and so you're less likely to fall down at the top.

> But training to balance on one leg doesn't mean that your 'balance' or 'fitness' overall improve. I'm gunna need a citation on that one. Training you balance is likely to increase your overall balance. Like, by definition. If you can stand on one leg well, then you have the muscles and the equilibrium to balance yourself. Therefore you are less likely to fall.

  I'm not making an empirical claim here. I am trying to explain why their results do not imply that "training to balance on one leg" causes good health outcomes. I'm saying that this experiment: 1. Does not define 'balance' 2. Does not show that the test they applied predicts or correlates with 'balance' 3. Does not show that 'balance' causes good health outcomes.

I put it with the correlation to health decline and grip strength. While training pure grip strength will not keep your health from declining, there is a natural tendency to increase grip strength with full body exercises and strength training, which help people live longer by increasing cardiovascular health and pushing blood to our extremities. There's even some (I'm not sure how much) research into this type of full body exercise helping ward off cognitive decline... but the articles focus on the grip strength, as that's the one through factor as you use your hands in body weight exercises, kettle bells, dumbells, martial arts, climbing, etc.

  A strong grip can sometimes prevent a bad fall. Grab the railing before you fall down the stairs.
