Researchers participating in the Multidimensional Intervention for Early Osteoarthritis of the Knee (Knee Study) determined that physically inactive, middle-aged people with symptomatic osteoarthritis benefitted equally from strength training regimens, self-management programs, or a combination of the two. Details of this study are available in the January 2010 issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. Osteoarthritis (OA) is the most common form of arthritis and the second leading cause of disability in the United States. Currently OA is the most prevalent chronic condition among women, afflicting 35-45% of women by the age of 65.
Researchers in Australia found that prolonged television viewing was linked to an increased risk of death, even in people who exercised regularly, and recommended more be done to encourage people to spend fewer hours sitting still in front of the TV. The study, which appeared online on 11 January in the journal Circulation, is the work of lead author Dr David Dunstan, a researcher at the Baker IDI Heart and Diabetes Institute in Melbourne, and colleagues. The researchers wrote that studies have been done on television viewing time and health, but these have focused on links with cardiovascular risk, and not risk of death. So for this study they investigated the link between prolonged television viewing time and all-cause, cardiovascular, cancer and non- cardiovascular/non-cancer mortality in Australian adults.
Athletes put less strain on their anterior cruciate ligament (ACL) while making a cut on a natural grass surface while wearing a cleat. This is the conclusion from a study by investigators at Hospital for Special Surgery (HSS) that tested the strain placed on the ACL of four different shoe-surface interactions: Astroturf/turf shoe, modern playing turf/turf shoe, modern turf/cleat, and natural grass/cleat. The study appears in the January 2010 issue of the Journal of Biomechanical Engineering. "It appears that a similar cut made on four different surfaces, the best strain profile is in grass/cleat combinations, " said Mark Drakos, M.D., formerly an orthopedic fellow in the Sports Medicine and Shoulder Service at HSS.
Aetna Launches New Team-Based Fitness And Nutrition Program To Help People Achieve Healthy Lifestyles
Aetna (NYSE:AET) today announced a new team-based fitness and nutrition program for employers nationwide that uses online social networking to encourage people of all health and fitness levels to work together with their colleagues to achieve their optimal health.

"We all know the health benefits of losing weight, being more active, quitting smoking, eating a healthier diet and more, but many people don't know where to begin and the thought of doing it alone is often daunting, " said Lonny Reisman, M.
University at Buffalo researchers are the first to show that a controlled individualized exercise training program can bring athletes and others suffering with post-concussion syndrome (PCS) back to the playing field or to their daily activities. In a paper published in the January issue of the Clinical Journal of Sport Medicine, the researchers report that a program of progressive exercise developed individually for each participant and performed at levels just below the onset of symptoms is safe and can relieve nearly all PCS symptoms. Their results counter the accepted wisdom that PCS should be treated with rest, reassurance and antidepressants, and that physical activity should be avoided.
Protein supplements don't improve performance or recovery time and, according to a recent study, such supplements are inefficient for most athletes. "They are often poorly used or unnecessary by both high-level athletes and amateurs, " says Martin FrÃ chette, a researcher and graduate of the UniversitÃ de MontrÃ al Department of Nutrition. FrÃ chette submitted questionnaires to 42 athletes as part of his master's thesis. Sportsmen were asked about their use of supplements while keeping a journal of their eating habits for three days. They came from a variety of disciplines including biathlon, cycling, long-distance running, swimming, judo, skating and volleyball.
