Aerobic & Cardio Articles

Anybody in the world needs to have physical activity. It doesn't matter who you are, cardiovascular activity is needed for well-being and a high quality of living. Lives can be better in all kinds of various ways with it's various advantages. There are two kinds of cardiovascular activity: aerobic and anaerobic. Why is it necessary to participate in either of these?

Muscle fatigue occurs when lactic acid is produced. Before more anaerobic is attempted the muscles must use this lactic acid up in a rest period. During anaerobics, oxygen is used by the muscles to restore burned energy. Training makes lactic acid removal in the body more effective. A few examples of anaerobic exercise are; sprinting, hill climbing, running intervals, jumping rope, and varied activities that take large spurts of energy.

Aerobic exercise is exertion that is usually lower in activity level and longer in duration. The term aerobic translates to with air or with oxygen. It is performed to condition the muscles to be more active for increased periods of time. It is often referred to endurance training or cross training. Swimming, biking, waliking, or jogging are some examples of aerobic exertion. To retain the body's exertion level, a large amount of oxygen is required to create the necessary energy. Aerobic exercise is very important for optimal health and enhanced performance.

When greater exertion level exercises are performed in a shorter area of time it is known as anaerobic activity. The term anaerobic translates to without air or without oxygen. As the body is worked in very strenuous activities it develops a chemical known as lactic acid to maintain it's energy. While aerobic exercise is performed to raise endurance, anaerobic exercise is to raise muscle strength for times when great amounts of energy are essential in a quick time.

In general, anaerobic exercise ends up burning less calories than aerobic exercise does, but it does build muscle and lean body mass. As more energy is burned with muscle that replaces fat cells, muscle and lean body mass inceaseIncreased muscle mass leads to lost weight and a leaner figure as muscle groups burn more energy than fat cells. As you start to exercise anaerobically, there is a shortage of oxygen to the muscles. With anaerobic training the body can become better equipped to handle fatigue. As the fitness level increases, the body produces less lactic acid and the disposal of it from the body becomes more efficient. With fortified muscles, the groups can perform from twelve percent - 50% more effectively, allowing the body to accumulate higher levels of lactic acid during exercise.

Anaerobic activity is usually for people who have already reached a certain amount of fitness and are trying to increase speed, agility, and strength. People need to do a good deal of aerobics warming up and muscle stretching previous to and after an anaerobic exercise session. It is not recommended to participate in anaerobic exercise if you are a pregnant woman. Also, if you are a novice to physical activity, you should begin at about fifty percent intensity level for your particular fitness degree.
