Aging Muscles: 'Hard To Build, Easy To Lose'
Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which decreases strength and increases the likelihood of falls and fractures. New research is showing how this happens — and what to do about it...

Back to Basics: Yes, Sergeant!
If Mark Roozen, a personal trainer in Colorado Springs, set his group conditioning classes to music, the playlist could start with “I’ve Been Working on the Railroad.” Mr. Roozen’s routines are as likely to incorporate logs, wheelbarrows and sandbags as circuit machines, Pilates equipment and other gym staples...

Slushies: the new weapon for exercising in heat
Reading up on Australian sports research for an upcoming magazine story, I came across this little nugget about dealing with competition in hot conditions.

They introduced ice vests at the 1996 Olympics (which have since become widely used commercial products), and in 2004 brought big bathtubs full of ice-water to the Athens Olympic venues, actually immersing their endurance athletes shortly before their competitions...


Phys Ed: Can Vitamin D Improve Your Athletic Performance?
When scientists at the Australian Institute of Sport recently decided to check the Vitamin D status of some of that country’s elite female gymnasts, their findings were fairly alarming. Of the 18 gymnasts tested, 15 had levels that were “below current recommended guidelines for optimal bone health,” the study’s authors report.
