A systematic review of physical activity promotion strategies

This article was first published in:British Journal of Sports Medicine:1996:30:84-89We have reviewed randomised controlled trials of physical activity promotion to provide recent and reliable information on the effectiveness of physical activity promotion. Computerised databases and references of references were searched. Experts were contacted and asked for information about existing work. Studies assessed were randomised controlled trials of healthy, free living, adult subjects, where exercise behaviour was the dependent variable. Eleven trials were identified. No United Kingdom based studies were found. Interventions that encourage walking and do not require attendance at a facility are most likely to lead to sustainable increases in overall physical activity. Brisk walking has the greatest potential for increasing overall activity levels of a sedentary population and meeting current public health recommendations. The small number of trials limits the strength of any conclusions and highlights the need for more research

Mapping the multiplicity of the self

In this commentary we offer a critique of the task devised by Hermans (2001): the PPR (Personal Position Repertoire). We first emphasize the important contributions made by Hermans and collaborators toward improving our understanding of the dialogical self, and then analyze several problems raised by this new method of studying the self. The issues we address are: the meaning of the concept of prominence; the possible reification of the positions adopted in this task; and the problem of the power differential between clients and psychologists.info:eu-repo/semantics/publishedVersio
