Final answer:
The amount of cardiorespiratory endurance needed varies depending on individual goals, capabilities, and overall health. The U.S. Department of Health and Human Services recommends adults engage in 2.5 hours of moderate-intensity aerobic activity or 1.25 hours of vigorous-intensity aerobic activity each week. However, for specific fitness goals or athletic training, more cardiorespiratory endurance may be needed.
Step-by-step explanation:
The amount of cardiorespiratory endurance needed varies depending on individual goals and fitness levels. According to the U.S. Department of Health and Human Services, adults aged 18 to 64 should engage in 2.5 hours of moderate-intensity aerobic activity or 1.25 hours of vigorous-intensity aerobic activity each week to maintain good cardiovascular health. This can be further broken down into about 30 minutes of exercise on most days of the week.
However, for specific fitness goals or athletic training, more cardiorespiratory endurance may be needed. For example, top cardiovascular athletes can achieve even higher levels of cardiac output during peak performance. Additionally, regularly engaging in aerobic activities can help build up endurance and make the heart stronger.
Ultimately, the amount of cardiorespiratory endurance needed is subjective and should be tailored to individual fitness goals, capabilities, and overall health. It is always best to consult with a healthcare professional or fitness expert to determine the appropriate amount of cardiorespiratory endurance exercise for specific needs.
