Children and adolescents (6-17) should do at least 60 minutes (1 hour) or more of moderate-to-vigorous physical activity daily. Aerobic: Most of the 60 minutes or more per day should be either moderate- or vigorous-intensity aerobic physical activity and should include vigorous intensity physical activity on at least 3 days a week.
According to the National Heart, Lung, and Blood Institute, moderate-intensity activities like walking or cycling enhance heart health by improving blood flow and reducing the risk of heart disease.
Specifically, exercise physiology dictates that low intensity, long duration exercise provides a larger percentage of fat contribution in the calories burned because the body does not need to quickly and efficiently produce energy (i.e., adenosine triphosphate) to maintain the activity. On the other hand, high intensity activity utilizes a ...
In general, it is performed at a moderate level of intensity over a relatively long period of time. For example, running a long distance at a moderate pace is an aerobic exercise, but sprinting is not. Playing singles tennis, with near-continuous motion, is generally considered aerobic activity, while activities with brief bursts of energetic ...
3. For additional health benefits, adults aged 65 years and above should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate-and vigorous-intensity activity. 4.
Then the intensity is raised if desired. [4] [5] [6] The exercise can be any activity that can be titrated, such as walking, jogging, swimming, using exercise machines, and these may be mixed to add variety. Increasing the intensity can be more challenging than increasing duration, and a heart rate monitor may be employed to track intensity.

Other studies have shown that exercise-based rehabilitation at a moderate intensity in heart failure patients improves cardiorespiratory fitness and increases both exercise endurance capacity and VO2max (12–31% increase). [15] More recent studies have examined the effects of high-intensity exercise on patients with heart failure.
