Question

Aerobic physical activity is done for longer time periods than anaerobic physical activity. Aerobic physical activity is better for the cardiovascular system than it is for strength endurance, while anaerobic physical activity is better at building strength endurance than it is at increasing cardiorespiratory fitness. Any activity done for longer than two minutes becomes an aerobic activity as the body adjusts to the activity and begins to supply sufficient oxygen to the muscles.

Answer 1

Aerobic physical activity is done for longer time periods and is better for the cardiovascular system, while anaerobic physical activity focuses on strength endurance. Exercising for longer than two minutes becomes an aerobic activity as the body adapts and provides sufficient oxygen to the muscles.

Step-by-step explanation:

Aerobic physical activity refers to exercises that are done for longer time periods and primarily use oxygen to meet energy demands. These exercises are beneficial for the cardiovascular system, improving endurance and efficiency. Examples of aerobic exercises include cycling, brisk walking, swimming, and rowing.

On the other hand, anaerobic physical activity involves high-intensity bursts of exercise that are performed for relatively shorter durations. Anaerobic exercises focus on building strength endurance and primarily use fast-twitch muscle fibers. Examples of anaerobic exercises include weight lifting, sprinting, and activities like basketball and tennis.

When aerobic exercises are performed for longer than two minutes, the body adjusts and starts supplying sufficient oxygen to the muscles, making it an aerobic activity.
