Cardiovascular
exercise raises the heart rate for an extended period of time, which improves
oxygenation throughout the body. Cardiovascular exercise is very important for
anyone who is looking to burn calories and lose weight. In addition to weight
loss cardiovascular exercise is good for the heart and lungs by building them
up and making them strong, it reduces stress and promotes healthy restful sleep
and reduces the risks of heart attack, high cholesterol, high blood pressure
and diabetes. All cardio exercise is good for the body and helps burn calories.
So which ones burn fat and burn fat the quickest?
Initially man thought that high
intensity cardio exercises would burn fat faster because you are increasing the
heart rate faster to burn more calories. This is true, however what scientists
figured out is that during high intensity cardio exercises the first thing the
body uses are glycogen, which are the bodies stored carbohydrates.
Carbohydrates are important for the body to use energy. However, the point of
doing cardiovascular exercise is to burn fat. What scientists figured out was
that during low intensity cardio exercises the body burns fat leaving the
glycogen stores for regular everyday activities. Still you would have to do a
lot of low intensity cardio to burn even 1 pound of fat because low intensity
exercises burn fewer calories than high intensity cardio.
Ultimately,
what man figured out was that even though low intensity cardio burns fat, high
intensity cardio boosts the metabolism to burn calories and continues to burn
calories long after a workout is through. So even though high intensity
exercises use glycogen stores first, once all of the stores are used up the
body moves on to fat stores. Additionally, after high intensity exercises the
body will convert food from later meals back into glycogen and store them for
energy, rather than turning the food into fat.
So
to get the most out of your cardio workouts it is important to do both high
intensity and low intensity cardio exercises. One way to do this is through
interval training. Interval training involves bursts of high intensity work
alternated by periods of low intensity or rest. An example of this would be
walking for 5 minutes then running for 5 minutes. Then walking for 3 minutes,
while the body has a chance to recoup and catch your breath, then run for 1
minute followed by walking 1 minute. And continue to alternate walking and
running for 1 minute each up to 20-30 minutes (depending upon how long your
workout is). No only will you burn more calories, you will burn more fat and
also increase your lung capacity so you catch your breath quicker and are able
to do more high intensity activities.
Implement
interval training into your workout plan. Or you can do one day of low
intensity and the next day high intensity. It is all up to you how you want to
implement cardio exercise into your exercise routine but remember it is
necessary so don’t leave it out.
