Aerobic Exercise/Cardio: Their Benefit and Some Drawbacks | You Must Read Before You Hit.
Aerobic
Exercise which is commonly known as cardio, is a physical workout which
includes low intensity to high intensity. During these exercises we use high
amount of bodily energy which works as fuel and later we take proper diet to
fulfil the required amount of energy absorbed during exercises.
When practiced in this way, examples of
cardiovascular/aerobic exercise are medium to long distance running/jogging, swimming, cycling, and walking,
according to the first extensive research on aerobic exercise, conducted in the
1960s on over 5,000 U.S. Air Force personnel by Dr. Kenneth H.
Cooper.
The two types of exercise differ by the
duration and intensity of muscular contractions involved, as well as by how energy
is generated within the muscle.
During
increased exertion, muscle glycogen is broken down to produce glucose, which
undergoes glycolysis producing pyruvate which then reacts with oxygen to
produce carbon dioxide and water and releases energy. If there is a shortage of
oxygen, carbohydrate is consumed more rapidly because the pyruvate ferments
into lactate. If the intensity of the exercise exceeds the rate with which the
cardiovascular system can supply muscles with oxygen, it results in build-up of
lactate and quickly makes it impossible to continue the exercise. Unpleasant
effects of lactate build up initially include the burning sensation in the
muscles, and may eventually include nausea and even vomiting if the exercise is
continued without allowing lactate to clear from the bloodstream.
Benefits:
There
are many health benefits of doing aerobic exercise in your daily life, some of
them we are quoting here.
·
Strengthening the muscles involved in
respiration, to facilitate the flow of air in and out of the lungs.
·
Strengthening and enlarging the heart
muscle, to improve its pumping efficiency and reduce the resting heart rate,
known as aerobic conditioning

Some drawbacks of aerobic exercise include are:
·
Overuse injuries because of
repetitive, high-impact exercise such as distance running.
·
Is not an effective approach to
building muscle.
·
Only effective for fat loss when used
consistently.
