Q

What are the 4 major findigns of the US surgeon generals report?

A

1) inactive people can improve health by becoming even moderately active on a regular basis.
2) PA does not need to be vigorous for benefits
3) Greater health benefits can be achieved by increasing the amount (duration, frequency, or intensity) of physical activity.
4) reduces the risk of developing or dying from some of the leading causes of illness and death in the United States.
