...killed when a Swedish tanker blew up in a Hamburg drydock. Loaded, the Europoort carries enough oil to pollute beaches from Holland to Spain, though Esso strictly bans any ocean discharges except in dire emergencies. Empty, the ship is as potentially explosive as nitroglycerin, with a rich mixture of oxygen and oil fumes in its massive tanks. To prevent inadvertent explosions, a Japanese company has designed an automatic system that forces inert, nonflammable gas into emptying tanks, thus displacing oil fumes. But such devices are not yet in general...
...ready to take patients, he is already swamped with applicants, many of them middle-aged men worried by the deadly statistics of heart-artery disease and premature deaths in the U.S. "I'm practicing preventive medicine," Cooper says. He believes that his measurements of heart action and oxygen metabolism under stress enable him to forecast with 80% accuracy whether a man is likely to have a heart attack within five years...
Four-Quart Goal. The amount of work that muscles do can be measured by the amount of oxygen they consume. Soon after Cooper entered the Air Force in 1960, he was assigned to its School of Aerospace Medicine near San Antonio. Using thousands of airmen as his captive subjects, Cooper hit upon a twelve-minute run (now recommended only for men under 30) as the basic test. If the greatest distance a man can cover in those twelve minutes is less than a mile, he is in Cooper's very poor" fitness category. If he weighs...
...cardinal requirement of aerobic exercise is that it must tax the person's capacity to the point where he is breathing hard and his heart is pounding at 130 beats per minute or more. Cooper grades exercises according to how fast they induce the training effect and increase oxygen use. Running and jogging rank first, followed by swimming, cycling stationary running, the handball-squash-basketball group of sports, and walking. An aerobics fan must attain a weekly score of at least 30 points on Cooper's scale. He may do this by walking three rules in no more...
...week. His wife Mildred accompanies him at least part of the four-mile way. With aerobics adopted at scores of Y.M. and Y.W.C.A. centers, hundreds of clubs springing up, and an estimated 8,000,000 Americans trying the system, Cooper has done much to increase the U.S. consumption of oxygen on a basis that is medically and physiologically sound...
