Aerobic exercise boosts the body's immune system and stamina, reduces the risks of diseases, cleans the arteries and helps maintain a healthy body weight. It also increases lifespan and enables an individual to manage conditions such as coronary artery disease.
Aerobic exercise refers to any activity that reinforces the heart and lungs, and enhances the ability of the body to use oxygen. These activities include walking, fogging, running, swimming and cycling. During these exercises, breathing becomes faster and deep, leading to increased blood and oxygen flow to the muscles. The blood vessels also expand to facilitate the oxygen and waste transport to and from the tissues respectively.
Aerobic exercise keeps the immune system active, hence reducing the chances of viral diseases such as the flu and colds. It also keeps the body healthy by minimizing the chances of developing conditions such as obesity, hypertension, type 2 diabetes, stroke and metabolic syndrome.
Aerobic exercise reduces low-density lipoprotein cholesterol while enhancing high-density lipoprotein cholesterol to keep the arteries clear of plaque buildup. This exercise also complements a healthy diet in preventing weight gain and maintaining a healthy body weight. Although an individual may feel fatigued after aerobic exercise, such a person gains stamina and endurance in the long run.
