Answer:
80%
Step-by-step explanation:
More than 80% of adults do not meet the guidelines for both aerobic and muscle-strengthening activities. Similarly, more than 80% of adolescents do not do enough aerobic physical activity to meet the guidelines for youth. Working together to meet Healthy People 2020 targets via a multidisciplinary approach is critical to increasing the levels of physical activity and improving health in the United States.
The Physical Activity objectives for Healthy People 2020 highlight how physical activity levels are positively affected by:
Structural environments, such as the availability of sidewalks, bike lanes, trails, and parks
Legislative policies that improve access to facilities that support physical activity
New to Healthy People 2020 are objectives related to policies targeting younger children through:
Physical activity in childcare settings
Behavioral interventions to reduce television viewing and computer usage
Recess and physical education in the Nation’s public and private elementary schools
