Aerobic exercise is considered to be any form of activity that increases the heart rate. Sustained movement is the focus of aerobic exercise. In order to be effective, MayoClinic.com recommends that you engage in some form of aerobic exercise on a daily basis. Aerobic exercise helps your heart, lungs and muscles maintain optimal strength and endurance.
Respiratory System
The respiratory system is responsible for providing the body with oxygen. Every cell, tissue and muscle in the body requires oxygen for life. Oxygen is carried in the blood, originating in the lungs, where a transfer of oxygen and carbon dioxide is exchanged.
Function
Aerobic exercise increases aerobic respiration, or the speed and efficiency at which blood gases and chemicals like glucose are exchanged between the lungs and the body as a form of energy. Aerobic exercise increases the exchange of oxygen and contains four phases; glycolysis, formation of coenzymes, synthesis of oxygen and hydrogen and the transport of proteins and electrons which create energy, according to California Baptist University. This process is known as the Krebs Cycle.
Benefits
Aerobic exercise is not only recommended for increased cardiovascular and strengthening benefits, but also to increase stamina, endurance and capacity of the lungs to perform more efficiently and effectively as they take in oxygen. As the heartbeat accelerates during aerobic exercise, so does the rate of exchange in the lungs, replacing carbon dioxide and de-oxygenated blood with oxygen-rich blood and nutrients for use by the working body. Start slowly, gradually building up duration and intensity as you feel your muscles, heart and lungs growing stronger.
Types
Aerobic exercises or activities that increase the heart rate are good for increasing respiratory function, endurance and capacity. Common forms of aerobic exercise include running, swimming, kickboxing and sports like tennis and handball. Any activity that utilizes larger muscle groups and is performed on a continuous basis is considered an aerobic activity, according to Georgia State University. Cross-country skiing, stair climbing, dancing and fitness walking are also popular and effective in weight loss, and in increasing cardiovascular health and respiratory endurance and function.
Cautions
Talk to your doctor before starting any exercise program that involves aerobics, especially if you've been diagnosed with a disease or chronic illness. Wear proper clothing according to the weather, and layer clothing so you can remove outer garments as you warm up. Wear breathable fabrics and cover your face with an insulating material when running or walking in frigid weather to help warm air before it enters your lungs, suggests MayoClinic.com.
