![]() ![]() ![]() Aerobic - means with oxygen in normal situations your muscles use energy (glucose) that requires the addition of oxygen (O2) the oxygen is captured in your lungs (respiratory) and transported to your muscles by your heart and blood vessels (circulatory) once combined with O2, the glucose fuels the muscle contractions and, thus, body movement aerobic exercise - a moderate form of exercise that is sustained over an extended period of time, generally involving the large muscle groups and placing a demand on the heart and lungs to deliver oxygen to the muscles aerobic exercises are most effective for developing cardiovascular fitness, for example, walking, jogging, cycling and swimming anaerobic - (without oxygen) as your muscles work faster and harder, they require more energy and, thus, more oxygen your lungs breathe deeper and your heart beats faster trying to keep up with the demand when your muscles demand for energy surpasses your lungs' and heart's abilities to deliver oxygen, your muscles have to burn energy (glycogen) without O2, which is used up fairly quickly and produces more waste products, specifically lactic acid anaerobic exercise - a form of exercise that involves short, intense bursts of energy anaerobic exercise can only be maintained for 1-2 minutes, slightly longer through specific anaerobic training. ![]()
