Answer

Aerobic physical activity is characterized by lower intensity, longer duration, and relies on oxygen for energy, while anaerobic physical activity is characterized by higher intensity, shorter duration, and relies on energy sources other than oxygen.

Explanation

Aerobic physical activity and anaerobic physical activity are two types of exercise that differ in their intensity, duration, and energy systems used.Aerobic physical activity, also known as endurance or cardio exercise, is characterized by lower intensity, longer duration, and is performed at a moderate level of intensity over a longer period of time. This type of activity primarily uses the aerobic energy system, which relies on oxygen to produce energy. Examples of aerobic activities include running, swimming, cycling, and walking. These activities increase heart rate and breathing, improving cardiovascular endurance and overall fitness.Anaerobic physical activity, on the other hand, is characterized by higher intensity, shorter duration, and is performed at a level of intensity that is too high for the aerobic energy system to meet the energy demands. Instead, anaerobic activities rely on the anaerobic energy systems, which do not require oxygen and produce energy through the breakdown of glucose and other nutrients. Examples of anaerobic activities include sprinting, weightlifting, and high-intensity interval training (HIIT). These activities lead to the buildup of lactic acid and require more energy in a shorter period of time.In summary, aerobic physical activity is sustained and relies on oxygen for energy, while anaerobic physical activity is short-lived and relies on energy sources other than oxygen. Both types of activities are essential for overall health and fitness, with aerobic activities focusing on endurance and cardiovascular health, and anaerobic activities focusing on strength, power, and speed.
