My son is involved in water polo and track. He recently broke his arm in an accident which made me wonder. Is one sport better for bones than the other?

One recent study found that overall bone density was better in impact sport athletes (those who play basketball, tennis, and so on) when compared to water sport athletes. No other differences were found between these two groups. However, both groups of athletes showed better bone health when compared to other kids the same age who weren’t physically active.
