It is hypothesized that the theoretical model of adherence
to exercise associated with the belief in health can provide a
plausible explanation for the significant differences
observed in this context. In this case, even when considering
that the harm to health caused by physical inactivity can be
present from an early age, individuals only tend to adopt
concepts of health promotion and disease prevention/
rehabilitation with regard to exercise when they grow older,
as they perceive the threat of and their vulnerability to
diseases.
