WARM IS BETTER
It is the influence of circadian rhythms
on body temperature that seems to yield
the most control over the quality of a
workout. When body temperature is at its
highest, your workouts will likely be more
productive; when your temperature is low,
chances are your exercise session may be
less than optimal. Body temperature is at
its lowest about one to three hours before
most of us wake up in the morning, in
contrast to late afternoon when body
temperature reaches its peak. (To determine
your own circadian peak, refer to
the box to the right.) Studies have consistently
shown that exercise during these
late-in-the-day hours produces better performance
and more power. Muscles are
warm and more flexible, perceived exertion
is low, reaction time is quicker,
strength is at its peak, and resting heart
rate and blood pressure are low.
Heart attacks occur most often in the morning, when blood pressure is highest. Although healthy individuals shouldn't worry about exercising in the morning, those with cardio risk factors should use caution.
