Remote and web 2.0 interventions for promoting physical activity

Abstract
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: Primary To compare the effectiveness of remote and web 2.0 interventions for PA promotion in community dwelling adults (aged 16 years and above) with a control exposed to placebo, no and/or minimal intervention. The influence of delivering the intervention to a group versus individually versus mixed (combined group and individually) will also be assessed. Secondary If sufficient data exists, the following secondary objectives will be explored: to assess how the professional delivering the intervention (for example health professional, exercise specialist) influences the effectiveness in changing PA; to assess how the intensity of the intervention delivery (for example frequency, duration of contact) influences the effectiveness in changing PA; to assess how the prescription of the intervention (for example duration, frequency, intensity) influences the effectiveness in changing PA.
