Final answer:
Aerobic exercise includes activities like running, swimming, and cycling; they are sustained, rhythmic exercises that improve cardiovascular health, endurance, and muscle oxygen use.
Step-by-step explanation:
Aerobic exercise stimulates the functioning of the heart and lungs. These exercises involve activities that use oxygen to meet the body's energy requirements during the workout. Running, swimming, and cycling are all examples of aerobic exercises that can enhance cardiovascular endurance and overall health.
What Makes an Exercise Aerobic?
An exercise is considered aerobic if it includes continuous and rhythmic physical motion that increases the heart rate and respiration while using oxygen to generate the body's energy. To qualify as aerobic, the activity must be at a level of intensity that can be sustained over an extended period.
Benefits of Aerobic Exercise
Aerobic exercise has numerous benefits, including improved cardiovascular health, increased muscular endurance, and more efficient oxygen use by muscles. Regular aerobic activities such as cycling, walking, and running can help make the heart stronger and improve overall fitness.
