Exercising for at least 30 minutes everyday is great for your health! You may have heard or read about this phrase more than once before and on many occasions while looking for health related help. Where you encountered these golden words of wisdom is not really the big deal, but knowing their importance is. I refer to them as words of wisdom first, because they are true and secondly because if you act on them they will change your life. We have heard or read time and time again that daily exercises when added to healthy eating can be the difference between spending our hard earned finances to pay for hospital bills and going on our favorite well deserved vacations. vh
To understand why exercising daily is a crucial part of a healthy lifestyle in the modern world we need to understand how the human heart functions. This is not to scare you, I am not about to tire you with hard to understand terminology, but rather layman’s reader digest version. We all know that a normal adult human heart rate is around 72 beats per minute. Of course this will vary depending on what the person is doing at any given time, for example the rate will drop significantly when one is asleep and rise beyond 72 when a person is working. Other factors such as stress, body weight or sickness may also cause the rate to rise. As I said before, I am going to restrict this explanation to exercising or involving in your favorite recreational sport.
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. vh
These muscles depending on their strength, determine how much blood goes out 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 beat.
