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:

  • b)
    break the heart record

Exercise helps the heart to beat slower

Exercise plays a significant role in improving cardiovascular health by making the heart more efficient. Here are some key points explaining how exercise helps the heart beat slower:

- **Improved Efficiency**: Regular aerobic exercises like jogging, cycling, swimming, and fast walking force the cardiovascular system to work harder, leading to increased blood and oxygen delivery to the muscles. This, in turn, makes the heart more efficient in pumping blood with each stroke.

- **Reduced Wear and Tear**: With regular exercise, the heart becomes stronger and more efficient, resulting in a slower resting heart rate. A slower heart rate indicates that the heart is functioning more effectively and experiencing less wear and tear.

- **Cardiovascular Health**: Exercise helps to prevent cardiovascular diseases by promoting better circulation and reducing the risk of plaque buildup in the arteries. The increased blood flow during exercise helps to keep the arteries clear and lowers the chances of heart attacks.

- **Release of Endorphins**: Exercise stimulates the brain to release endorphins, which act as natural painkillers and help to control stress and mood. This can contribute to a sense of well-being and improved mental health after a workout.

In conclusion, regular exercise not only benefits the heart by making it beat slower but also promotes overall cardiovascular health, reduces the risk of heart-related issues, and contributes to better mental well-being.
