We know that muscles get stronger by repairing the micro-tearing that happens during a workout. So are bones also strongest where they’ve healed from a break?
Like every other question in the field of human health, the answer is yes … and no. A broken bone heals with the formation of a “callus” at the break. Your body directs calcium to that point, but because you’re not putting that broken bone to work, the rest of that bone becomes weaker (while the bone at the break that’s healing becomes stronger).
When the cast comes off, the healed area is, in fact, stronger than the surrounding bone. But this difference is rebalanced when we return to regular activity.
Of course, unless you’re recovering from a broken bone, the idea of “building bone strength” might not occur to you. Nobody’s selling magazines with the “5 Moves for Your Sexiest Skeleton.” But bone strength is just as important as muscular or cardiovascular health. Just like muscles, our bones rely on us to keep them in good health. And as we age, skeletal health can make the difference between staying active or losing our ability to walk.
