Have you noticed a fluttering heartbeat or heart palpitations
during your weight workouts or shortly after? Should you be unnerved about this experience?
“Weightlifting
due to the muscular exertion delivers an increased return of blood to the heart
due to the pumping effect of skeletal muscle,” says Dr. Ronald Scheib, MD, cardiologist,
Medical Director at Pritikin Longevity Center & Spa in Miami.
“By abruptly
increasing the volume of blood returning to the heart chambers, it will
increase the pressure and produce dilatation of the chambers that are involved
in controlling heart rhythm,” continues Dr. Scheib. “As a consequence,
abrupt lifting weight can produce transient arrhythmias.”
Don’t let
the medical lingo frighten you; this occurrence is benign. If you’re having heart
palpitations seemingly related to lifting weights, there’s yet another possible
cause.
And that’s
anxiety, which can be over anything, including your weight lifting regimen. In
between weight lifting sets you may find yourself worrying about something,
such as a relationship or job situation, and as a result, you have palpitations.
The weight lifting didn’t cause the
palpitation, but that just happens to be what you were doing shortly before you felt it. The mix of increased blood volume and stress can bring
on heart palpitations.
These benign possibilities don’t mean that
you can’t have an actual pathology that needs treatment. Pay attention to when
your heart has palpitations and see if there’s a pattern.
See a cardiologist and maybe get some tests just to make sure all is fine. I know for a fact that in my case, extreme
anxiety can bring on heart palpitations (my MR angiogram and echocardiogram
were normal).
