Physical Activity and health promotion
Regular
physical activity
confers physiological, metabolic benefits
Claude Bouchard, PhD, Steven N. Blair, PED, and William Haskell, PhD, Editors
Research has repeatedly shown that
exposure to regular, frequent bouts of
physical activity stimulates physiological and
metabolic changes that benefit health. It is
helpful to classify these as either (a) chronic
effects, that is, adaptations to training acquired
over weeks or months, or (b) short-term,
acute responses to each individual session
of activity. Health-related adaptations to
training are dealt with in other chapters. This
chapter describes selected acute responses
that are clearly related to health outcomes
and explains their relevance. The extent to
which these responses benefit health depends
on the type, frequency, and regularity of
activity and the extent to which particular
acute responses persist into the postactivity
period. For people who achieve the minimum
recommended amounts of physical activity
(Haskell et al. 2007, p. 1423), acute responses
should be stimulated on five days per week
(for moderate-intensity activity) or three days
per week (for vigorous intensity). For reasons
often related to statistical power and logistical
considerations, the experimental models used
to study acute health-related responses have
relied mainly on planned, structured exercise,
as opposed to physical activity performed
during daily living. For this reason, the term
exercise predominates in this chapter rather
than physical activity. Studies of short periods
of detraining are included because they
illustrate that the changes to health outcomes
that are rapidly lost when regular training is
interrupted are mainly attributable to acute
effects. Intuitively, unstructured periods of
physical activity may be expected to stimulate
acute responses that are qualitatively similar
to, but less conspicuous than, those arising
from planned sessions of exercise.
