Exercise has the capability to improve many aspects of health, yet nat
ional surveys have indicated that the general population is not exerci
sing sufficiently for such benefits to accrue. With a great proportion
of the population attending general practices each year, general prac
titioners have a unique opportunity to increase the prevalence of exer
cise. With such a realization, 'exercise on prescription' schemes, in
which general practitioners prescribe exercise as an alternative to me
dication, have become increasingly popular within the United Kingdom.
However, few guidelines as to good practice exist. This paper aims to
bridge this gap prior to the availability of detailed evaluations, by
drawing upon the experiences of a scheme established in 1993 by the LI
FE Project, a community-based heart disease prevention programme. The
scheme currently has 22 general practices referring patients to a coor
dinator who decides upon the most appropriate form of exercise prescri
bed after an introductory consultation and a health check. To date, ov
er 600 patients have been referred. The paper focuses upon various asp
ects associated with exercise on prescription including patient select
ion, targeting of general practices and leisure venues, ethical consid
erations, adherence issues, and the most appropriate specific exercise
options.
