Two recent research papers provide very different answers. Several weeks ago, information in this column reported on the different physical activity recommendations that exist for the public.
Some experts advocate 'moderate lifestyle' activities.
Other experts argue for a public health prescription of more vigorous exercise. Two recent research papers intensify this discussion even further. Participants in this study were approximately 40000 women over the age of 45 years. A very interesting review article on the validity of current exercise guidelines concludes that the intensity of physical activity is MOST important. The suggestions in this paper are both interesting, and controversial.
