Harder is not necessarily
smarter, especially when it
comes to exercise.
According to a study recently
published in the Journal of
Applied Physiology
(2007;103,432-42), researchers
wanted to find out which methods
of exercise would have the
greatest impact on low-density
lipoprotein (LDL-bad
cholesterol) and high-density
lipoprotein (HDL-good
cholesterol).
The study followed 240
sedentary and overweight
subjects assigned for 6- months
to one of four exercise groups:
non-exercise control;
high-amount / vigorous-intensity
exercise; low-amount/
vigorous-intensity exercise; or
low-amount/ moderate-intensity
exercise.
At the end of the study,
researchers discovered that the
low-amount/ moderate intensity
exercise group experienced
“sustained reduction in
very-low -density lipoprotein”
during 15 subsequent days of
detraining, where as the more
vigorous groups showed
