Answer #1

Answer :

Exercise intensity related to the health rate :

Exercise intensity means how much energy is expended when exercising, it is varies from one person to another.

* The normal heart rate is 72 - 80 beats per minute.

* If the activity or exercise is doing by person the heart rate is increases.

* when doing exercises the oxygen need is very important to the tissues or cells for getting energy.

* So that the blood circulation may increases by increasing heart beat or heart rate.

* So exercise intensity may increases the heart rate.

* the maximum heart rate up to 220

* so to get exercise intensity we have to subtract our age from 220 .

* for example one person age is 50 years, we need to subtract from 220 .

* so 220 - 50 = 170 .

* so the maximum heart rate for 50 years old is 170.

* here the exercise intensity is 50 - 70 % from our maximum heart rate.

* so here for 170 exercise intensity is 85 - 119.

So by doing exercises the need of energy also high, so exercise intensity high heart rate also high.
