The technical definition of aerobic exercise is “any form of exercise or activity that uses the aerobic metabolism — meaning oxygen is heavily involved in the cellular reactions that provide the body with the energy necessary to perform activity,” explains Michael Jonesco, DO, an assistant professor of internal and sports medicine at the Ohio State University Wexner Medical Center in Columbus. “You’re making yourself more efficient at delivering oxygen to the rest of the body.”
In general, to increase your aerobic fitness you should exercise intensely enough to reach your target heart rate range. Your target heart rate range is 60% to 80% of your maximum heart rate. A general formula to determine your maximum heart rate is 220 minus your age. (For example, if you are 50 years old, your maximum heart rate is 170 and your target heart rate range is 102 to 136.) Check your heart rate as you exercise and try to keep it within your target heart rate range.

Your heart rate rises during aerobic exercise. It can rise from 70 beats per minutes (bpm) at rest to as high as 170 bpm or even higher during exercise, depending on the intensity of the exercise, your fitness level, your age, and other factors. Whether you're training is aerobic or anaerobic is determined by the intensity of your workout, and monitoring the intensity is the key to know which one you're doing.
Aerobic capacity is a measure of the ability to perform oxidative metabolism. Multiple systems are involved, including the pulmonary, cardiac, vascular, and musculoskeletal systems. Patients with MD have lower aerobic capacity, especially those patients with aggressive forms of MD (Sockolov et al., 1977; Edwards, 1980; Haller and Lewis, 1984; Lewis, 1984; Wright et al., 1996). Poor aerobic capacity results in reduced activity levels. Other organ dysfunction, such as decline in pulmonary status and cardiomyopathy, may further contribute to declining levels of aerobic capacity.

Higher intensity exercise, such as High-intensity interval training (HIIT), increases the resting metabolic rate (RMR) in the 24 hours following high intensity exercise,[24] ultimately burning more calories than lower intensity exercise; low intensity exercise burns more calories during the exercise, due to the increased duration, but fewer afterwards.


Observe basic safety while walking outside. Watch for traffic all around you. Always walk on sidewalks or on the left side of the street facing traffic if there is no sidewalk. Carry an ID and a cell phone or change for a pay phone. Use caution if wearing headphones (perhaps use just one earpiece so you can hear traffic and other noises around you). Make yourself visible in low-light situations by wearing reflective gear, such as vests with reflective tape are especially visible.

Aerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process.[1] "Aerobic" means "relating to, involving, or requiring free oxygen",[2] and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism.[3] Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time.[1] What is generally called aerobic exercise might be better termed "solely aerobic", because it is designed to be low-intensity enough so that all carbohydrates are aerobically turned into energy.


Walking is a low-cost and effective form of exercise. However, the wrong type of shoe or walking action can cause foot or shin pain, blisters and injuries to soft tissue. Make sure your shoes are comfortable, with appropriate heel and arch supports. Take light, easy steps and make sure your heel touches down before your toes. Whenever possible, walk on grass rather than concrete to help absorb the impact.

Form: Stein says it doesn't matter whether someone is swinging his or her shoulders or walking straight from the hip, as long as they're comfortable and have the right intensity. Hoffmann, however, says it's best to have elbows bent at a 90 degree angle, the arms swinging freely so that they come up to about chest level, the fingers curled into a loose fist, and the feet moving forward at a brisk pace. "If your hands are just dangling at the sides, you're probably not walking fast enough to get any heart rate increase," says Hoffmann, who notes that the extremely sedentary and overweight can begin an exercise plan with a stroll and work up to a quicker pace.
The heart has four chambers that fill with blood and pump blood (two atria and two ventricles) and some very active coronary arteries. Because of all this action, the heart needs a fresh supply of oxygen, and as you just learned, the lungs provide it. Once the heart uses what it needs, it pumps the blood, the oxygen, and other nutrients out through the large left ventricle and through the circulatory system to all the organs, muscles, and tissues that need it.
