The increase or decrease in heart rate – assuming all other factors are kept constant, will dictate the amount of energy the heart will require to pump sufficient blood to all parts of the body. Remember the body systems need oxygen in order to accomplish their particular functions. The heart on the other hand needs energy as well, but is usually self sufficient as long as one is not extremely starving.
By the way if you do not know, the heart is made up of muscles. These muscles depending on their strength, determine how much blood goes out of the heart to rest of the body. It therefore means a heart with stronger muscles pumps more blood than a weaker one. Also remember it does not matter whether you are sleeping, sitting in your living room or doing recreational running, a heart beat is a heart beat. What this means is, we can only manipulate the heart rate but not the type of heart beat.
What makes a strong heart? Well literally speaking, stronger heart muscles. This sounds easier than done, but with determination it can surely be done. I am not talking of surgical procedures, I am talking of exercising. When you exercise or engage in any of your favorite recreational sport such as walking, jogging, swimming, running among others daily, you are actually pushing or training your heart to work harder.
A word of caution, do not be tempted to start and accomplish everything in one day if you are beginner, take one step at a time. You can read more about this in another related article at Recreational sports for life website. When you continue stressing your heart with exercise, you are increasing its strength. This in turn makes it more powerful and as a result pumps more blood (oxygen) with fewer heart beats. The arteries become bigger and stronger allowing for more and more blood to flow out of the heart. This is what makes it easier for athletes to play their sports successfully.
If you started out walking for one mile in 30 minutes, you will soon see one of these two things happening. You will cover the same distance with less time or cover more distance with the same time, whichever way you win. Now if you are looking to cut down some weight, you will begin to see some positive results especially if you continue exercising daily.
Do not forget that the amount of calories burned depends on the amount of work done, the more the better. So the more you exercise, the stronger your heart will be and consequently, the more work you will accomplish without overworking your heart. Using fewer heart beats to do more work (or burn calories) is the main goal. Another word of caution though is to eat healthy; you need energy to burn calories!
It is a fact that extra body weight causes the heart to work harder to supply enough blood to the whole body. That is why before you begin exercising your resting heart rate may be as high as 70, but after few weeks of committed daily exercises, you will see a significant drop. What this means to you is, if you help you heart to work less, by exercising daily, you will help it to last longer. Save those heart beats now when you can for later on in life, they will be precious when you cannot exercise as much due to age.
