years, we've heard the phrase, "No pain, no gain," with respect
to exercise, but that might not be as accurate as once thought.
Recent studies are indicating that when you exercise, your
threshold for pain may actually be a warning, rather than
a gauge of progress.
A study that appeared in the February 2004 issue of Preventive
Medicine compared two groups of 30 college students who were
subjected to incremental treadmill exercise tests. Investigators
measured the transition from aerobic (with oxygen) to anaerobic
(without oxygen) activity. Researchers theorized that once
an exerciser completes the transition to the anaerobic state,
exercise becomes uncomfortable - and even painful. It is this
painful or uncomfortable stage of exercise that researchers
say should be a hint to "ease up."
The study authors concluded that the perceived transition
to anaerobic exercise is a good indicator of nonproductive
exercise, and a good monitor for regulation. In other words,
when you're exercising and you start to feel uncomfortable,
it may be time to stop! Talk to your chiropractor about designing
a moderate exercise program suitable to your needs.
