Question

4 — physical activity guidelines
learning objective: determine individual physical fitness guidelines to improve health.
which of the following scenarios falls within the current physical fitness guidelines for adults?
a.) 300 minutes of moderate activity per week, with two days of muscle strengthening exercises.
b.) 200 minutes of moderate activity one day a week.
c.) 100 minutes of moderate activity per week, with one day of muscle strengthening exercises.
d.) a brisk 20 minute walk each day.

Explanation:

Current physical activity guidelines for adults recommend at least 150 minutes of moderate - intensity aerobic activity per week (or 75 minutes of vigorous - intensity), and muscle - strengthening activities on at least 2 days. Option a has 300 minutes (more than 150) of moderate activity and 2 days of muscle strengthening, which fits. Option b: 200 minutes in one day is not spread out appropriately. Option c: 100 minutes of moderate activity is less than 150, and 1 day of muscle strengthening is less than the recommended 2. Option d: A 20 - minute walk daily totals 140 minutes per week, less than 150, and no mention of muscle strengthening.

Answer:

a.) 300 minutes of moderate activity per week, with two days of muscle strengthening exercises.
