Scientists find sleep deprivation affects athletic performance considerably

New research shows a lack of sleep can cause an athlete performance to fall significantly. The research, carried out by scientists at the University of California, showed energy expenditure during submaximal exercise decreased 3.9 percent; maximal aerobic power decreased 2.9 percent and time to exhaustion decreased by 10.7 percent (37 seconds). Submaximal heart rate decreased after sleep restriction, as well as peak heart rate and Psychomotor Vigilance Test response speed.
