U of S studies effects of exercise and ibuprofen

It's a problem many of us face as we grow older...the loss of bone density and muscle mass.

Exercise can help slow that process butU of S kinesiology professor, Phil Chilibeck, said

exercise can also cause inflammation, which breaksdown muscle and bone.

"If there's too much inflammation, too much damage that might impair the repair process. And that mightbe one of the problems with aging is that you don't recover as well."

So Chilibeck is following up on a small American study that suggested taking a common over the

counter pain medication, ibuprofen, right after exercise might help reduce damaging inflammation.

"It looks like preventing inflammation was important for not only building muscle mass and strength but also building bone as well."

Chilibeckis putting about 100 women, who are 59 and older, through a nine month study.

Nancy Allan is one of them. Since March she's been exercising for an hour, threetimes a week.

After each session half of the participants are given ibuprofen. The others get a placebo.

"I think I'm getting it because I haven't had one slight physical sign that I've been exercising. No stiffness, no nothing the next day so that makes me think I'm taking the real thing. But I don't know."

Chilibeck expects participants who receive the ibuprofen will see about a fiveper cent increase in bone density. And that would translate into a substantial 25 per cent reduction in the chances of getting a fracture. He saidhe'll apply to do an even more extensive study of exercise and ibuprofen ifthe results of this study are positive.
