Healthy, older adults free of heart disease need not fear that bouts of rapid, irregular heartbeats brought on by vigorous exercise might increase short- or long-term risk of dying or having a heart attack, according to a report by heart experts at Johns Hopkins and the U.S. National Institute on Aging (NIA). Researchers say such fears surfaced after previous studies found that episodes of errant heart rhythms, more formally known as non-sustained ventricular tachycardia, more than double the chance of sudden death in people who have already suffered a heart attack. In a study presented Nov. 16 at the American Heart Association's (AHA) annual Scientific Sessions in Orlando, the research team monitored for on average 12 years the medical records of 2, 234 initially healthy men and women, ages 21 to 96, and participating in the NIA's Baltimore Longitudinal Study of Aging.
Strength training exercises using dumbbells can reduce pain and improve function in the trapezius muscle, the large muscle which extends from the back of the head, down the neck and into the upper back. The exercises also improve the muscle's ability to respond quickly and forcefully among women suffering trapezius myalgia, a tenderness and tightness in the upper trapezius muscle. The results are the latest findings from an ongoing Danish study aimed at reducing repetitive strain injury caused by office work. Repetitive strain injury has become increasingly common. The authors cited two recent Danish surveys, one of which found that more than half of female office workers reported frequent neck pain.

The artificial lower limbs of double-amputee Olympic hopeful Oscar Pistorius give him a clear and major advantage over his competition, taking 10 seconds or more off what his 400-meter race time would be if his prosthesis behaved like intact limbs. That's the conclusion - released to the public for the first time - of human performance experts Peter Weyand of Southern Methodist University in Dallas and Matthew Bundle of the University of Wyoming. The Weyand-Bundle conclusion is part of a written Point-Counterpoint style debate published online in the Journal of Applied Physiology on Nov. 19. Weyand and Bundle were the first two authors of the study publishing the test results acquired as part of the legal appeal process undertaken after the governing body of Track and Field - the International Association of Athletics Federations (IAAF) - banned Pistorius from able-bodied track competitions, including the Olympics.
Parents who sign their children up for sports as part of an educational experience and to learn about teamwork may be learning some of the same lessons themselves, according to new research from Purdue University. "People often think about how youth sport benefits children because of physical activity, self-confidence and friendships, but we found that parents also are affected when their children play organized team sports, " said Travis Dorsch, a doctoral student in health and kinesiology who led the study. While children are making friends and learning to work well in groups, parents are practicing the same behaviors in the stands and on the sidelines.
For many Americans finding time to get in the recommended 30 minutes a day of exercise can be almost as difficult as discovering the lost city of Atlantis. According to the Loyola Center for Fitness just because you're glued to your desk doesn't mean you can't exercise. "Taking a break from work for even a few minutes can help you feel better and increase your energy level, " said Kara Smith, special programs coordinator for the Loyola Center for Fitness. Here are some exercises that allow you to work out in the three main fitness categories, cardiovascular, strength and flexibility, at or near your desk. "If co-workers give you a strange look while you're exercising ask them to join you, " said Kara.
