I found this
interesting article in one of my favorite online publications, Outside
Magazine. The author Claire Martin points out some of the positive
benefits of load bearing exercise, especially on increasing bone
density. Important info for any age! Have a healthy and happy holiday

So you've swapped
your running shoes for swim goggles and a life membership at the
pool, thinking that no-impact sports mean no physical wear and tear.
Not so fast. Contrary to popular fitness wisdom, such a move might
undermine your health down the road. A recent study clinched what
a few researchers already guessed: Since bone tissue breaks down
and rebuilds itself not unlike muscle tissue, stress from high-impact
sports involving running, and load-bearing activities like backpacking
and weight-lifting, can actually strengthen bones.
In the broadest
study yet of bone density, conducted at Australia's Edith Cowan
University, doctors surveyed 60 female athletes and found that those
who had engaged in high-impact sports for 20 years had much stronger
bones than those who swam. "This should alert men and women
in their twenties and thirties to start now," says Barbara
Drinkwater, a Seattle-based physiologist and one of the country's
leading bone density experts. "A lifetime of running and jumping
exercises is crucial to bone strength."
mean enter a marathon tomorrow. While stronger bones guard against
injury, repetitive impact can predispose athletes to stress fractures.
So it's wise to ease into any new high-impact sport. Start off slowly
and increase your duration and intensity by no more than 10 percent
each week. "If you tend to overdo everything, running 80 miles
a week, you'll have problems," Drinkwater says. "Run three
miles a day and you'll be fine."
