Cardiovascular endurance consists of maintaining an increased heart rate and breathing rate for a longer period of time. Cardiovascular endurance can be accomplished through consistent exercise performed for prolonged periods of time. Cardiovascular exercise improves your body's ability to bring oxygen from the environment, into the lungs, and diffused into the bloodstream. With an increase flow of oxygen to cells in the body will help them work to their capacity. In addition, cardiovascular exercise helps the heart become bigger and stronger (it is a muscle), allowing more blood to be pumped out with each beat. If more blood is pumped out with each beat, the heart does not have to beat as fast or work as hard.

Find the low and high target heart rate zones for a 46-year-old teacher from El Cerrito Middle School with a resting heart rate

alexgriva [62]

The low and high target heart rate zones for the 46-year-old teacher with a resting heart rate of 78bpm are;

Low target heart rate = 87 bpm

High target heart rate = 131 bpm

We are told that the resting heart rate of the 46 year old teacher is 78 bpm.

Now, the formula for calculation of the estimated maximum age-related heart rate is;

Maximum age related heart rate = 220 – person's age

For this 46 year old man;

Maximum age related heart rate = 220 - 46

Maximum age related heart rate = 174 bpm

Now. since his resting heart rate is average at 78 bpm, then the low and high target heart rate will be gotten from the formula;

Low target heart rate = 50% × Maximum age related heart rate

High target heart rate = 75% × Maximum age related heart rate

Thus;

Low target heart rate = 50% × 174

Low target heart rate = 87 bpm

High target heart rate = 75% × 174

High target heart rate ≈ 131 bpm
