Another standers of fitness that is often cited is fit enough to protect against heart attack. there is, of course, no absolute protection against heart attack. but stamina training ( to be described in detail letter) does appear to reduce the risks.
Here's what happens. suppose you decide to train for stamina by swimming. as you swim, your heart begins to beat faster and harder. it pumps more blood through your body with each beat. After you have trained for a while, your heart will pump fewer times. yet each pump will send more blood to your muscles. you won't feel as tired, even after swimming for so four, because you have improved your stamina. at the same time you will have strengthened your heart and artery system.
the normal pulse rate of a resting adult is about 70 beats per minute. it can be 80 to 90 beats in untrained individuals. by comparison, the resting pulse rate of person who has built up stamina can be 55 to 60 beats a minute, or even less.
when you are fit, your heart doesn't have to pump as often because each pump delivers more blood. therefore, a fit person's heart beats several thousand times less every day than an unfit person's heart. this appears to reduce the wear and tear on the heart valves and blood vessels.
