The Evolution of Physical Activity Promotion.

A physically active lifestyle has numerous physical and mental health benefits for patients of all ages. Despite these significant benefits, a majority of Americans do not meet current physical activity guidelines. Health care providers, especially nurses, play a vital role in physical activity promotion. Over the past several decades, exercise and physical activity guidelines have evolved from a focus on structured, vigorous exercise to a focus on moderate-intensity "lifestyle" physical activity. The author updates nurses on physical activity guidelines and provides tips for promoting physical activity, with a focus on lifestyle activities such as walking to work. This article also addresses new research findings on the importance of decreasing sedentary and sitting time, even in physically active people. [ABSTRACT FROM AUTHOR]
