Question

To reduce risk for chronic diseases, the physical activity guidelines recommend that most adults should perform at least.

Answer 1

To reduce chronic disease risk, most adults should perform at least 150 to 300 minutes of moderate-intensity, or 75 to 150 minutes of vigorous-intensity aerobic activity per week, plus muscle-strengthening activities twice a week.

Step-by-step explanation:

To reduce risk for chronic diseases, the 2018 Physical Activity Guidelines for Americans suggest that most adults perform a significant amount of physical activity weekly. According to the guidelines, adults should aim for at least 150 minutes (2 hours and 30 minutes) to 300 minutes (5 hours) of moderate-intensity aerobic activity per week, or 75 minutes (1 hour and 15 minutes) to 150 minutes (2 hours and 30 minutes) of vigorous-intensity aerobic physical activity, or a combination of both. Moreover, muscle-strengthening activities should be done on 2 or more days per week.

Moderate-intensity activities are those where you can talk but not sing during the activity, while vigorous activities are at a level where you cannot say more than a few words without pausing for breath. The aim of these recommendations is not only to reduce disease risk but to improve overall health including cardiovascular and muscular fitness, bone density, and cognitive function.

Answer 2

should perform at least 2-5 hours of moderate physical activity a week
