Question Description
One remarkable change in recent years is that millions of people worldwide spend several hours a week in vigorous exercises. Ask any jogger the reason for running a considerable distance come rain or shine, and the answer almost certainly will be: “It makes me feel so good.”Exercise of this kind, which makes the heart and lungs work harder, undoubtedly has a pleasant effect, provided of course, that the program has a doctor’s approval. Jogging, cycling, swimming and fast walking, all of which work the heart and lungs, are known as aerobic exercises.They force the cardiovascular system to deliver more blood and oxygen to feed the increased needs of the muscles. The heart is eventually more efficient, delivering more blood and oxygen with each stroke. A slow heart rate is often a sign of long term authentic activity.A world-class runner may have a heart beat at forty strokes a minute, less than half the average. If the heart beats more slowly and more efficiently, wear and tear on it and the arteries is clearly reduced. As disorders of the cardiovascular system head the list of fatal diseases in many countries, any move to cut their toll is beneficial. The heart pumps harder during exercise, the blood surges through the arteries. This,say some doctors, discourages plaque, a substance that coats the artery walls, hinder in the flow, often causing heart attacks. Exercise may stimulate the brain to release endorphins, painkillers with a similar structure to morphine as well as their analgesic effect. Endorphins are believed to help control stress and mood. This may explain why so many people feel better mentally after a work out. Exercise helps to build bones and improves the muscles. Stronger bones ward off the dangers of the degenerating condition known as osteoporosis. A large muscle is more effective, more flexible and produces more energy. Better muscles help us to work with less fatigue.On the basis of your reading of the passage, choose the correct option:Q.
