High-impact exercise good for bones

LOS ANGELES Researchers studied hundreds of male and female athletes who took part in the 2005 National Senior Games in Pittsburgh.

They found those who competed in high-impact sports such as basketball or track and field had better bone mineral density than those who participated in lower impact sports.

Even the researchers say they were surprised to find that active adult participation in high impact sports had such a positive influence on bone health for mature athletes.
