Anaerobic Exercise Vs Aerobic Exercise - Which is Better For You?

When it comes to promoting weight loss and cardiovascular health, almost everyone thinks of aerobic exercise as the solution. Although it may be the most popular choice and it is not necessarily obvious the best solution. Secondly anaerobic exercise, has incredible benefits that are often overlooked.

First let's clarify aerobic and anaerobic in terms of the dependence of oxygen. We like organisms need oxygen at all times. Although oxygen is not considered aerobic and anaerobic depends depends oxygen, this is only in molecular terms. Whether you wind sprints or running a marathon as a body breathe and use oxygen all the time.


Oxygen is just one variable among different ways of energy. Therefore, exercises that are considered aerobic in nature like running or cycling with low to moderate intensity for a long time, get their energy mainly oxygen-dependent pathways of energy. While the exercises that are considered anaerobic in nature, such as weightlifting and sprints are shorter and more intensity, mainly get their energy not dependent pathways of oxygen.


Aerobics are considered beneficial for cardiovascular health, people tend to choose activities that are low to moderate in intensity but longer duration on activities that are higher in intensity but much shorter. Therefore aerobic vs anaerobic battle.  


Currently, the activities that are considered aerobic or anaerobic are not so different in terms of energy. Activities requiring different ways of energy are briefly explained as follows:


    
The activities are very rich in intensity that requires a lot of energy very quickly through the use of energy phosphagen. This energy path does not depend on oxygen.


 It supplies energy quickly, but only for a short period. Indeed, it follows from the energy from an energy rich element called "phosphates" which is stored in skeletal muscles in very limited quantities. Because of its limited supply, phosphate discharges quickly (10 seconds or less). However, in about 5 min almost all phosphate is again reset to zero and is stored in skeletal muscle.


    
Activities that are high in intensity and longer duration (up to 2 minutes), use the path of glycolysis for energy. The path of the glycolytic energy uses glucose is stored as glycogen in the body, because it is a source of energy.  


This energy pathway functions in the absence of oxygen and converts glucose into energy, but also produces lactic acid as unpleasant by-product. At this intensity, the body can not metabolize or get rid of the lactic acid as fast as it is produced. Lactic acid builds up and causes havoc in skeletal muscles affected his ability to do the job. This is known as the lactate threshold or anaerobic threshold.


    
Activities that are mild to moderate in intensity and more than 2 minutes long used the route energy from oxidation. This energy pathway is oxygen dependent. As in the path of the glycolytic energy use of glucose in the body because it is a source of energy. However, this pathway converts glucose to pyruvate enter the Krebs cycle. 


 The Krebs cycle is very efficient and produces energy from glucose without producing lactic acid as a byproduct. Therefore, more energy is produced as required longer duration of activity. This energy pathway may also use fat as a suitable source of low energy intensity. However, the process is very slow and inefficient, especially in terms of performance.

Although these energy pathways are different in their processes, which are closely interdependent. Let's look at how the energy pathways work together during an activity such as running: heating by jogging for 10-15 minutes at an easy pace. In this present body does not need to resort to the anaerobic energy pathways by which oxidative pathway uses energy to lead the race.


 After warming up, increase the pace and make a 400-meter race in a moderate to high intensity. In this intensity both phosphagen and energy pathways involved in glycolysis. After 400 meters, finishing with a sprint of 60 m. 

 The immediate energy demand for such intense activity but of short duration high can only be ensured through energy phosphagen. Cool Running on low for 800m. The oxidative pathway provide energy during cooling.

As shown in the example above, the three energy pathways simultaneously working at all times and our bodies naturally knows when and how perfectly emphasize good energy path as dictated by the intensity and duration of the activity.  


When just looking at the facts, it becomes clear that anaerobic vs. Aerobics is more semantic than anything else. Aerobic exercise has received more attention and has been associated with better health in comparison with what is anaerobic counterpart. The truth is that both are under the same umbrella.

Fitness should be considered as a whole and not in parts. You should be more concerned with participation in activities or exercises that stimulate all the energy pathways rather than any aerobic or anaerobic training. 


 The body is naturally intelligent and distinguish whether or not we do not "aerobic" or "anaerobic" exercise. Simply responds by providing the necessary energy required by the activity.
