A new study has shown that racehorses are extremely sensitive to changes in daily light and, contrary to humans, can adapt very quickly to sudden shifts in the 24-hour light-dark cycle, such as those resulting from a transmeridian flight, with unexpected benefits on their physical performance. http://phys.org/news238149648.html Biology Tue, 18 Oct 2011 09:41:02 EST news238149648 For obese seniors, dieting and exercise together are more effective at improving physical performance and reducing frailty than either alone. http://phys.org/news220724570.html Medicine & Health Wed, 30 Mar 2011 17:50:09 EST news220724570 The endothelium is the inner lining of our blood vessels and normal functions of endothelial cells include enabling coagulation, platelet adhesion and immune function. Endothelial dysfunction is associated with reduced anticoagulant properties and the inability of arteries and arterioles to dilate fully. http://phys.org/news215694566.html Chemistry Mon, 31 Jan 2011 11:10:10 EST news215694566 In the largest study to date of the Arthritis Foundation's Tai Chi program, participants showed improvement in pain, fatigue, stiffness and sense of well-being. http://phys.org/news208411446.html Medicine & Health Mon, 08 Nov 2010 04:30:01 EST news208411446 (PhysOrg.com) -- New research suggests that athletes and footballers may want to limit the time they spend training at altitude to improve their performance. http://phys.org/news197046224.html Medicine & Health Tue, 29 Jun 2010 16:04:20 EST news197046224 (PhysOrg.com) -- Anti-aging supplements made up of mixtures might be better than single compounds at preventing decline in physical function, according to researchers at the University of Florida's Institute on Aging. In addition, it appears that such so-called neutraceuticals should be taken before very old age for benefits such as improvement in physical function. http://phys.org/news193415477.html Medicine & Health Tue, 18 May 2010 15:50:01 EST news193415477 More than one-third of adults ages 65 and older fall each year in the U.S., and, according to the Centers for Disease Control, 40 percent of all seniors admitted to the hospital are there due to injuries from falls. However, a new study has found that falls are not just a problem for older adults. Researchers have found that people in their 20s and 30s have significant issues affecting their balance, indicating an increased risk for falling. Carmen Abbott, an associate clinical professor in the University of Missouri School of Health Professions, has developed a screening test that could quickly diagnose an individual's risk of falling at any age. This primary fall prevention strategy could then be used to reduce the risk of falling. http://phys.org/news188654590.html Medicine & Health Wed, 24 Mar 2010 13:40:04 EST news188654590 Rats fed a high-fat diet show a stark reduction in their physical endurance and a decline in their cognitive ability after just nine days, a study by Oxford University researchers has shown. http://phys.org/news169209397.html Medicine & Health Tue, 11 Aug 2009 12:00:04 EST news169209397 When participants performed a mentally fatiguing task prior to a difficult exercise test, they reached exhaustion more quickly than when they did the same exercise when mentally rested, a new study finds. http://phys.org/news154678090.html Medicine & Health Tue, 24 Feb 2009 06:08:49 EST news154678090
