Evaluating physical activity

Physical activity as a public health intervention is still a relatively
new concept and although the health benefits of activity are widely
acknowledged (1) there is still no consensus as to the most effective
way of getting people to become more active. This has led to calls
for ‘properly designed’ evaluation studies (2) and has elevated
the importance of finding out what works. This article examines
evaluation methods and looks at the dilemmas and some of the
successful approaches experienced by the author.
