What is the recommended duration for vigorous exercise per week according to cardiorespiratory guidelines?

1. 50 minutes

2. 75 minutes

3. 120 minutes

4. 150 minutes

The correct answer is: 75 minutes

The recommended duration for vigorous exercise per week according to cardiorespiratory guidelines is 75 minutes. This is based on the physical activity guidelines provided by reputable health organizations, which suggest that adults should engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity each week. Vigorous exercise is defined as activities that significantly raise the heart rate and breathing rate, leading to improvements in cardiovascular fitness and overall health. Engaging in this level of exercise helps in reducing the risk of chronic diseases, improving mental health, and promoting weight management. While some options suggest longer durations, the key guideline is the balance between moderate and vigorous activities, with the 75 minutes for vigorous exercise providing a clear benchmark for those aiming for a higher intensity in their workouts. This reflects the current understanding of how different intensities of exercise contribute to overall health.
