Anaerobic VS Aerobic Exercise
The words aerobic and anaerobic refer to energy pathways that are utilised during exercise. Aerobic means "with oxygen" and anaerobic means "without oxygen".
Fat needs oxygen to burn completely so in order to burn fat during an exercise we need to move slowly and smoothly. This enables muscle cells to be supplied with enough oxygen to continue with its aerobic capacity and utilize fat as the main energy source.
Anaerobic exercise requires moving at an increased pace or with greater effort. Exercising this way burns more calories but results in a greater demand for oxygen which cannot be delivered in sufficient quantities to allow cells to continue burning fat. When we breath heavy we start to develop an oxygen debt and muscle cells switch to burning mainly carbohydrates, this fuel burns quickly and does not require oxygen.
Anaerobic exercises such as sprinting or weight training require more effort and up to 95% of the fuel used will be carbohydrates.
Although anaerobic exercises burn more carbohydrates they can be important in any weight loss program. They help burn fat indirectly by increasing the metabolic rate after an exercise session. Fitness expert Tom Venuto has taught thousands of people worldwide exactly how to utilize anaerobic exercises to burn the stored fat indirectly. Aerobic Exercise to burn fat directly.
Aerobic exercise like walking or swimming will burn a greater percentage of body fat. Aerobic exercise is an effective way to lose fat only if you are motivated enough to workout frequently, aerobics only burn fat during the workout so if you want encouraging results you need to be able to exercise daily and for longer periods.
Anaerobic exercise burns more calories than aerobic exercise because each movement generates more force from the cells. However when muscle cells contract with more force they switch to using carbohydrates as the main energy source. This type of exercise may seem incorrect for weight loss but in fact it helps produce an adaptive response with a side effect of an increased metabolic rate. During periods of rest the cells accelerate the fat burning process.
Aerobic exercise can develop into anaerobic exercise
Most exercises can be performed as aerobic (burn fat) or anaerobic (burn mainly carbohydrates) the terms simply refer to the energy pathway required. For example walking is easy and a good aerobic exercise but if we increase the effort the body moves faster, eventually we end up running which then uses the anaerobic energy pathway. The Anaerobic pathway means oxygen uptake becomes insufficient for fat to continue to be the main fuel source.
In fact most exercises or movements we perform result in a split between the fuels used, for example if the effort is about average like vacuuming a room or washing a car then we'll probably be burning about 50% carbohydrates and 50% fat.
Fast weight loss will come when the individual performs each exercise correctly and within their own unique capacity.
Calorie Burning Facts On Exercise
Calorie burning can be increased by controlling how we exercise. Different exercises burn various amounts of energy and some use different fuels. Take a look at some facts about burning calories.
- Calorie burning is higher when exercise is performed for longer periods
- If exercise is performed at a faster pace more calories will be used
- A higher number of calories are burned when exercise becomes intense
- The heavier an individual the more energy burned during exercise
- The more lean weight an individual possesses the more energy burned during rest
- Fitter people tend to burn more fat during exercise
