Heart rate drop

Heart rate drop

Post by Michael J. Gils » Fri, 19 Feb 1993 18:38:14


Three weeks ago, as has happened once before, I had a dramatic drop in
heart rate vs. effort in running.  If it follows the pattern of the
last time it happened ('91), my heart rate will be about 10% lower for
the same effort for the rest of the season.

Example: 4 weeks ago I ran 9 miles at a guilt-producingly easy pace of
9:00/mile.  My heart rate was ~163 bpm.  This weekend, I ran 18 miles
at same pace with a heart rate of ~148.  No change in diet, sleep,
temperature, terrain, etc.  I'm not unhappy with the result, I just
want to know what is happening and why.  

My workout schedule is on a three week cycle:

        Week 1 (recovery):

                Monday -     stretch
                Tuesday -    Swim, Bike 1 hr each
                Wednesday -  Lift, Run 6
                Thursday     Swim, Bike 1 hr each
                Friday       Lift, Run 7 (short hills)
                Saturday     Swim 1.5 hr, Bike 1 hr
                Sunday       Lift, Run 9-10 Fartlek

        Week 2 (intensity)

                Monday -     stretch
                Tuesday -    Swim, Bike 1 hr each
                Wednesday -  Lift, Tempo Run
                Thursday     Swim, Bike 1 hr each
                Friday       Lift, Run 6 (steep hills)
                Saturday     Swim 1.5 hr, Bike 1 hr
                Sunday       Run 9-10 Cutdown each mile + Bike 2 hr

        Week 3 (endurance)

                Monday -     stretch
                Tuesday -    Swim, Bike 1 hr each
                Wednesday -  Lift, Run 9-10 mile cutdown every 3 miles
                Thursday     Swim, Bike 1 hr each
                Friday       Lift, Run 8 (long hills)
                Saturday     Swim 1.5 hr, Bike 1 hr
                Sunday       Run 18 easy + Bike 1.5 hr

Heart rate drop

Very interesting.

This just happened to me last night on my trainer.
I was in the same gear and same resistance as
usual.  I was feeling the same pe (perceived exertion)
level but my HR was about 10 beats lower than normal.
I also had a hard time keeping it at that lower level.
I could understand a higher HR meaning I was a little
tired or over trained, but lower?

Somebody please explain this.

Could this be the "second-wind" or "runners high" (today's term - "in
the zone") that trained athlete's have (claim to have).  

I have always practiced relaxation techniques while training.  I can
actually feel a cool wash come over myself when I reach this point.
However, my perceived exertion level does not remain the same but
instead decreases.  Performance increases as I get to the point of
feeling no pain.  This is a real natural high....

Back when I was in high school (13 years ago) my doctor did a stress
test on me and and I recall using my relaxation technique after being
on the treadmill for awhile.  I recall that the nurse (who was
watching the heart monitors) called the doctor over - they looked at
the numbers and then began checking the connections.  They found that
my heart rate had dropped about 10 beats/min.   Usually they tested
fat, middle aged, heart attack risk patients - so at the age of 16, I
was not their normal test case.  This happened a few times throught
the test.  My heart rate would rise - level - and then drop somewhat
less than the rise - at each increased level of exertion.  It was as
if once the body found a rythm for a given level of exertion, it
could then relax somewhat.  This is basically what the doctor said to
me.

Since that test I have not persued this matter any.  However I have
continued to use my relaxation technique with success in both cycling
and running.  Only once swimming have I had this occur - I think this
is because I am too up-tight while swimming.

I don't use a heart rate monitor (afraid of what to do if it does not
beep) so I can't say that I have seen any numbers of this lately.  I
guess I'll have to borrow one for awhile to check this out.  I
believe that the key is efficiency though.  Your body finds an
efficient method to do the task asked of it and it then requires less
work from the heart and other body parts.

After a break (ie 5 days or maby it was the candies?) I am sometimes
about 10 bpm higher and I can hold it no problem.  This winter I have
spent about 1 month 5 to 10 bpm below what I held last year.  It
is not exhaustion and I am fairly sure that it is not sickness (a flu
did not seem to do much to me).  There are many factors that effect
your pulse and that is why researchers do not use pulse data for anything.
The important thing is *** volume and most likely if you are cranking out
the same power then your stroke volume has gone up to compensate for the
lower pulse.  What does it mean?  You got me.  If you are worried you could
go and get a fitness test with an EKG and see if there is anything abnormal
in your heart rhythms.  Get a copy of the actual charts for future reference.
  Life was so simple before I got my HRM.
