Physical activity is widely recognized as an important component of overall health and well-being. Current federal guidance continues to examine the relationship between physical activity, sedentary behavior, and health outcomes across different age groups.
The current Physical Activity Guidelines for Americans, developed by the U.S. Department of Health and Human Services, state that adults can receive substantial health benefits from 150 to 300 minutes of moderate-intensity aerobic activity each week, 75 to 150 minutes of vigorous-intensity aerobic activity, or an equivalent combination of the two. The guidelines also include muscle-strengthening activities on at least two days each week.
Research reflected in the guidelines has also expanded understanding of how physical activity can affect health. Evidence shows that physical activity is associated with benefits involving cardiovascular health, blood pressure, type 2 diabetes, certain cancers, brain health, bone health, and physical function. For older adults, regular physical activity is also associated with a lower risk of falls and fall-related injuries.
Another significant finding is the relationship between sedentary behavior and health. Current guidance emphasizes that adults benefit from moving more and spending less time sitting. Research has shown that even relatively small increases in moderate-to-vigorous physical activity can provide health benefits, particularly among people who are not regularly active.
The guidelines also no longer require physical activity to occur in sessions lasting at least 10 minutes. This reflects evidence that shorter periods of activity can contribute to overall health benefits. Additional benefits are associated with activity beyond 300 minutes of moderate-intensity activity per week.
