What is the minimum duration of an moderate intensity intermittent bout of aerobic activity to promote and maintain health?
The correct answer is A. 10 minutes. Current physical activity guidelines recognize that aerobic exercise bouts of at least 10 minutes in duration contribute meaningfully toward weekly moderate-intensity activity targets.

Why each option
Current physical activity guidelines recognize that aerobic exercise bouts of at least 10 minutes in duration contribute meaningfully toward weekly moderate-intensity activity targets.
The ACSM and the U.S. Physical Activity Guidelines for Americans specify that intermittent bouts of moderate-intensity aerobic activity must be a minimum of 10 minutes to count toward the recommended 150 minutes per week. Bouts shorter than 10 minutes have not been demonstrated to provide the same cardiorespiratory and metabolic health benefits as sustained or longer increments.
15 minutes exceeds the minimum threshold; while beneficial, it is not the defined minimum duration recognized in established guidelines.
20 minutes is a common prescription for continuous aerobic sessions but is not the minimum intermittent bout duration specified by health promotion guidelines.
30 minutes represents the total daily accumulation goal for moderate activity, not the minimum single-bout requirement.
