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. http://www.physorg.com/news177702312.html Medicine & Health Tue, 17 Nov 2009 22:50:02 EST news177702312 The antioxidant quercetin is increasingly being marketed as a supplement that boosts athletic performance, but a new University of Georgia study finds that it is no better than a placebo. http://www.physorg.com/news171193319.html Medicine & Health Thu, 03 Sep 2009 11:00:02 EST news171193319 (PhysOrg.com) -- Drinking beetroot juice boosts your stamina and could help you exercise for up to 16% longer. A University of Exeter led-study, published today, shows for the first time how the nitrate contained in beetroot juice leads to a reduction in oxygen uptake, making exercise less tiring. http://www.physorg.com/news168787342.html Medicine & Health Thu, 06 Aug 2009 15:40:09 EST news168787342 Divers who held their breath for several minutes had elevated levels of a protein that can signal brain damage, according to a new study from the Journal of Applied Physiology. However, the appearance of the protein, S100B, was transient and leaves open the question of whether lengthy apnea (breath-holding) can damage the brain over the long term. http://www.physorg.com/news168598483.html Medicine & Health Tue, 04 Aug 2009 09:55:06 EST news168598483 When soldiers leave base for a 3-day mission, how much water should they bring? Military planners and others have long wrestled with that question, but new research from the Journal of Applied Physiology may now provide them an accurate answer. http://www.physorg.com/news166253246.html Medicine & Health Wed, 08 Jul 2009 06:28:06 EST news166253246 A team of experts in biomechanics and physiology that conducted experiments on Oscar Pistorius, the South African bilateral amputee track athlete, have just published their findings in the Journal of Applied Physiology. Some of their previously confidential findings were presented to the Court of Arbitration for Sport (CAS) in Lausanne, Switzerland in May of 2008. Other findings are now being released for the first time. http://www.physorg.com/news165500340.html Medicine & Health Mon, 29 Jun 2009 14:50:01 EST news165500340 A new study in the The Journal of Applied Physiology, suggests that astronauts need to modify their workouts to avoid extensive muscle loss during missions onboard the International Space Station (ISS). http://www.physorg.com/news157894348.html Medicine & Health Thu, 02 Apr 2009 12:34:00 EST news157894348 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://www.physorg.com/news154678090.html Medicine & Health Tue, 24 Feb 2009 06:08:49 EST news154678090 Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society. The findings may help explain why people with sleep apnea are more likely to suffer strokes and to die in their sleep. http://www.physorg.com/news150461826.html Medicine & Health Tue, 06 Jan 2009 10:57:06 EST news150461826
