Defining Aerobic Activity
The term 'aerobic' is used to describe the exercise or activity that requires oxygen in order to efficiently produce the necessary amount of energy by the body to execute the activity.
The human body makes use of three different energy systems which fuel the body amid activity: at the beginning of the activity, then amid acceleration and finally to support endurance.
Amid this process the body quickly works to satisfy all of the elements required for the activity - using glucose, fatty acids, amino acids - pulling from stored sources and working towards creating a chain reaction that will fuel the body throughout the workout.
The Endurance Factor, Heart & Lung Health
The element of endurance involves the skeletal muscle which requires a satisfactory supply of oxygen from the heart to the lungs in order to maintain the activity for an extended amount of time. All too often, we forget that the human heart is simply a giant muscle which requires strengthening in order to remain in a healthy state.
If the heart itself were the only factor involved, we could do plenty to ensure that it continues to beat strong by performing aerobic related activity. Those include the following: a brisk walk that gets the heart rate up, running, jumping rope, water or snow or cross country skiing, roller or ice skating, or any other activity which increases heart rate.
However, it's not all about the heart. Let's look at other factors which impact heart health.
1. The lungs are a big part of the healthy heart picture; and because we're doing all of these fun aerobic activities - if we don't smoke and if we reside in a relatively low polluted area where the air is clean, then we're doing quite a lot for lung strength.
2. Here is where we get into trouble where the heart is concerned. We can perform all of the most aggressive exercise in the universe yet if our daily diet contains large amounts of saturated fats - as well as total fats, the negative results of these foods play out an unwanted scene within our arteries.
The arteries are the fuel lines to the heart - much like the fuel lines work in cars, carrying fluids back and forth which keep the engine running. When these lines become blocked, the engine stops - just as clogged arteries become narrowed due to build-up and create issues for even the strongest of hearts.
For those who have been blessed with awesome genes, plaque accumulation within the arteries may be greatly lessened. While being as active as possible is an excellent road map to follow where optimum health is involved, the genes are the most controlling factor.
Many an individual has gone through their life in an obese state to have lived up into their nineties - and some even longer. These individuals never watched their dietary habits - and some even smoked on a regular basis. Many would argue that these individuals would have lived even longer if they had watched their daily diets as well as avoided smoking. We'll leave it at that because at this point, it's all subjective.
