I am 38 and in great shape (workout 4 or 5 times a weak), and I have
found that if I do highly intensive workouts like heavy sprints or
running stairs fast, I will get nauseated and often throw up. Does
this mean I have something wrong with my heart or something or is it
just the way I am? I played sports competitively in college in this
happened then too. Now that I am older I guess I care more about these

Hello, bigsini-ga! 

 What you are experiencing is not that unusual. Many elite and amateur
athletes get nauseous or throw up after intense bouts of exercise. I
cannot tell you how many times I have watched members of my son's
hockey team come off the ice and retch behind the bench!

 With that said, it is always a good idea to get an annual physical to
make sure your doctor begins to establish a baseline for you as you
get older and to rule out any potential medical issues. And of course,
if your nausea and vomiting become worrisome for you, or begin to
occur at other times as well, please make an appointment for a
thorough evaluation as soon as possible.


Take a look at the posts on the following forum and you will find that
you have a good deal of company. Ingesting food too close to a workout
can be a problem. So can ingesting too little food, which can result
in low blood sugar. Not enough water, too much heat, equilibrium
changes, etc, can all contribute to nausea or vomiting during or after

See "Throwing up after working out."


From "Nausea During Workout," by Stew Smith. September 22, 2005,13190,Smith_092205,00.html

"Often, I receive an email concerning that nauseated feeling you can
get when exercising. There are a few issues that can cause this
uncomfortable feeling as well as many ways to prevent it."

"In my experience, that nauseated feeling has nothing to do with how
good of shape you are in. I have seen many people (including myself)
who are above average athletes toss their cookies during workouts. We
used to joke in my younger days that "if you are not throwing up at
the end of a PFT you are not trying." That is about as true as the
saying, "No Pain - No Gain". Here are some of the things that can
cause and prevent this unpleasant feeling:

From Wikipedia:

"Exercise induced nausea is a feeling of sickness or vomiting which
can occur shortly after exercise has stopped as well as during
exercise itself. It may be a symptom of either over exertion during
exercise, or from too abruptly ending an exercise session. People
engaged in high intensity exercise such as aerobics and bicycling have
reported suffering from exercise induced nausea. A study of 20
volunteers conducted at Nagoya University, Japan associated a higher
degree of exercise induced nausea after eating. It has been suggested
that exercise induced nausea could be caused by increased endorphin
levels, which are released while exercising. Endorphins have been
associated with nausea and vomiting, so this theory is plausible, but
unsupported by evidence."


From PubMed:

"Exercise-induced nausea is exaggerated by eating."  Appetite. 2001;

"This study was conducted to determine whether and under what
circumstances exercise causes nausea. Twelve healthy volunteers (20-37
years), including six athletes, participated in the study. Subjects
were studied on seven occasions. Each subject performed low and
high-intensity exercise without eating, immediately after eating a
beef patty and 60 min after eating. Besides these exercise
experiments, effect of meal on nausea was studied in each subject for
180 min without exercise. Exercise was done on a bicycle ergometer for
60 min at 40-50% maximal heart rate reserve and 20 min at 70-80%
maximal heart rate reserve. Subjects were tested for nausea by visual
analogue scales. Both low and high-intensity exercise caused nausea.
Scores for nausea were greater during exercise at fasting state and
immediately after eating than those without exercise (p<0.05 during
low-intensity exercise, and p<0.01 during high-intensity exercise).
Immediately after eating, scores for nausea were greater during
high-intensity exercise than during low-intensity exercise (p<0.05).
During high-intensity exercise, scores for nausea were greater
immediately after eating than without eating (p<0.05). There were no
differences in ratings for nausea between the sexes in any of the
experimental conditions.

** "Training did not decrease exercise-induced nausea. In conclusion,
exercise causes nausea, the severity of which is related to exercise
intensity and food intake, but not sex differences nor physical


The importance of cooling down to prevent venous pooling:

"It is important in an exercise routine to "cool down" (keep moving
for several minutes at low intensity such as slow jogging, walking, or
marching in place) after a workout. This allows blood, rich in oxygen,
to be distributed from the working muscles to the brain and other
organs of the body, thus preventing blood from pooling in muscles that
are no longer active.

* This phase prevents the dizziness, nausea, and muscle cramps that
can occur after a workout."



 Finally, you might want to reevaluate the anaerobic portion or your
workout - perhaps tone it down a little with some shorter sprints with
adequate rest periods in between. Pay attention to whether you are
pushing yourself too hard. See if that helps a bit.

 I hope the references I have provided serve to ease your mind a bit.
