Final answer:
The ideal duration of cardiorespiratory endurance exercise is about 60 minutes per day, which aligns with health guidelines to maintain cardiovascular health and improve overall fitness.
Step-by-step explanation:
The ideal duration of cardiorespiratory endurance exercise should be about 60 minutes per day. This amount of time is sufficient for vigorous aerobic activity that can significantly benefit cardiovascular health. According to the U.S. Department of Health and Human Services (HHS), adults should engage in at least 150 minutes of moderate-intensity aerobic activity per week, or 75 minutes of vigorous-intensity aerobic activity. These recommendations can be translated to approximately 1 hour per day. Some examples of vigorous aerobic activities include playing basketball, running, or swimming. Not only does such exercise help maintain a healthy cardiovascular system and improve overall fitness, but studies also show that it can reduce the risk of several chronic diseases and potentially extend life expectancy.
