From San Diego, at the Experimental Biology 2005 meeting
Athletes who perform short, high-intensity activities benefit from training their lungs as well as their arms and legs. A new study points to one reason why.
Exercise physiologist Lorrie Brilla of Western Washington University in Bellingham and her colleagues trained 15 physically fit and healthy 22-year-olds to strengthen muscles that drive respiration. Five days a week, the volunteers would suck air forcefully through a training apparatus 60 times while their noses were pinched closed. No air entered the mouth until the suction reached 75 percent of an individual's maximum sucking capacity.
