Having the size of a fist, the human heart is a pear-shaped, hollow organ through which blood is pumped to all part of the human body. The heart is a member of the circulatory system of the human body which is responsible for the supply of nutrient and oxygen in the body, and also helps in moving out carbon dioxide and so many other waste products in the body. The heart is made of muscle tissues and rests for only a fraction of seconds within each beat.
It is very important that the heart keeps beating ceaselessly as it is the powerhouse of the circulatory system. The heart is very important to the extent of being capable of causing the death of a human if it stops beating for just some few minutes.
For a lifespan of 76 years, the human heart moves nearly 169 million liters of blood and nearly 2.8 billion beats.
The heart rate is the total number of times a persons heart beats per minute, it can also be termed as a pulse. As heart rate varies between people, having a good knowledge of your pulse or heart rate can help in monitoring the heart health status.
This is same as the cardiovascular output which comprises of both the heart rate and the stroke volume. The stroke volume is same as the volume of blood pumped by the heart within a minute. This is normally not monitored as it is more important to have a good knowledge of the heart rate or pulse.
Through the monitoring of the heart during exercise, you can be able to keep track of your fitness level and safety. You also get to track your success level or the progress attained as a result of your exercise.
Most athletes have slow heart rate, this is because the heart muscles are been strengthened when you engage yourself in much physical training. This physical activity or exercise makes the heart to beat at a lower rate but yet still pumps an equal amount of blood just as the fast beating ones. The heart needs not work in order to pump blood when carrying out exercise. One who carries out much exercise will have a resting heart rate of about 40 to 60 beats per minute.
The following are the reason why its very much important to monitor your heart rate during an exercise:
Monitoring your heart rate during exercise is very important as it helps you to determine your maximum heart rate. The maximum heart rate, in essence, can be used to determine from an aerobic point of view the type of exercise or workout that is good for you. Monitoring your heart rate will also serve as an indicator of how fit you are. Those who are fit falls within the heartbeat of 50 to 60 per minute at a resting level, while unfit persons have a resting heart rate or pulse falling within 80 to 90 beats per minute.
We can now say that the maximum heart rate of a person is the number of beats you are expected to aim for during exercise. It happens to be a certain percentage of the maximum heart rate, which is between 50 to 70 percent.
In essence, to determine your maximum heart rate means to determine the optimum fitness level required of you, so you don’t have to workout your body system. In essence, you are guaranteed of effective and safe exercise when your heart rate is been monitored during exercise.
When monitoring your heart rate during exercise, you can be able to determine if you are overtraining yourself to gain your fitness. You are likely to be exposed to health problems. When you overtrain beyond expectation, issues such as low blood pressure due to dehydration can put you at risk. According to the American Council on Exercise, you have a higher chance of being exposed to infection as a result of chronic overtraining or exercise.
Just as the issue of overtraining or exercise, the act of monitoring your heart rate can be a good way of gauging your level of fitness and training. This, in essence, helps you to avoid making exercise without getting to the required target of fitness.
When you are not getting to the required level of exercise, you can not burn out enough calories if you are actually trying to lose weight. In this situation, cardiovascular endurance and building of strength will not be attained.
Looking at it from an economic point of view, you end up paying much money and wasting useful time in the name of going to the gym for exercise.
