Swim vs. Bike/Run Heart Rates?

Swim vs. Bike/Run Heart Rates?

Post by Chuck Amsle » Sat, 17 Jul 1993 16:50:29


Recently I've started paying serious attention to my training heart
rates (in order to get a feel for intensity levels in preparation for
starting a more scientific/systematic training regime).  It seems to me
that I've read somewhere that percent-of-maximum heart rate levels are
lower for swimming than for biking and running but I cannot find
anything about it now (including in the rec.sport.triathlon FAQ).  If
anyone could confirm or dispel this notion, I'd be appreciative.  If
it is true, about how much less are the heart rates?

This is indeed true.  In general, your max heart rate for swimming is
10-15 beats per minute lower than for land exercises (running, biking,
etc).  Although I've never read anywhere as to why this is, the masters
coaches here at Stanford suspect that it's probably because when your
body is prone in the water, your heart doesn't have to work as hard
against gravity to pump *** throughout your body.  The cooling
effect of the water also means that your heart doesn't have to work
as hard to circulate *** to keep you cool.  Just my 2 cents...

This is possibly true, but I would like to add one thought:

For some reason, perhaps that You use Your arms, You must keep a much slower
pace when swimming compared to the 'legs sports'. You can't keep a 'sprint'
speed when swimming 1500-4000 meters, but when running or biking You can keep
a pace not far from Your maximum without getting stiff immediately.
   And, honestly, do You spend as much time on swimming as on running and biking?
Some ten years ago I was an elite swimmer and today when 'tri-ing', I get
more or less the same heart rates for all the legs. So, perhaps it's a matter
of being able to push yourself in the swim-leg? I would be glad to hear from
other former swimmers who have compared the heart-rates for the different exer-
cises.
   BTW, I have also learnt that (swimming in particular) if You have been an
elite athlete in one of the legs, You have an ability to pull in another gear
when it comes to short sprints compared to the rest of the bunch, even if You
are more or less equal in longer distances.

 A good book on the whole subject of swimming is one put out by the IOC
Medical Commission by Costill, Maglischo and Richardson (1992), Blackwell
Scientific Publishing, Oxford. On pg 14 is described the *** reflex common
to many mammals whereby just putting your face underwater lowers heart rate by
5-8 bpm. Pg 172 describes swimmers as having heart rates 8-10 bpm lower than
during similar levels of effort (%VO2max) on land.
This however hasn't stopped my HR hitting 190 in the pool!

(In case you hadn't noticed I'm new to this system and apologise for the
peculiar item before. Please bear with me I'll have it figured soon, after all
it can't be as tough as a 200 fly !)

With all these articles about heart rate in-the-pool versus on-land, I
was wondering how people measure their heart rate in the water.  Do
you have a waterproof pulse monitor?  Do you stop swimming and just
count your pulse?  (You can run and count your pulse in principle, but
swimming and counting your pulse would be tough.)

It's the research, stupid.

I use to swim 8x25 meters (approx 10 seconds rest between each but the
last, where I rest 5 seconds). Immediately when I stop the last one,
I count my pulse in ten seconds and multiplies it with six. In ten
seconds, the pulse is quite constant after the above described series.
   If You are very used to counting the pulse, I think You could do
that in six seconds and multiply that with ten, but then there might
be counting-errors, by the fact You only count in six seconds.

I think the safest thing to say about heart rates is that they are very
variable.  Mine gets very high.  I know other swimmers who just cannot get
their heart rates high.  I've had coaches in the past who try and make you
do sets with a certain heart rate.  Two of us who swam together would be
amused, since I could (almost) sit on the edge of the pool and get my heart
to the desired (moderate) level, while he couldn't get it to that rate
while racing!  What seems to be more important than max heart rate is your
recovery time.

A few years ago when I was living in Belgium, we did a few test sets with
waterproof electrodes on and a receiver in our caps.  The set was either
5 x 400 or 6 x 200 with a couple of minutes rest in between, since the coach
was taking a drop of *** from our ears to measure lactate acid.
After the set, you would plug the receiver into the computer/printer and get
a graph of your heart rate throughout the set.  On the last 400 I got up
to 211.  My heart rate was a fair bit higher than the other swimmers, but
I also had the steepest recovery curve and would be back below 80 within
a minute.  (I was 27 years old then.)

I've heard that your swimming max heart rate is about 10 beats per minute
less than your cycling max heart rate, and that your cycling max heart rate
(on the road, so with some cooling from the breeze) is about 10 less than
your running max heart rate -- but I have no reference to back that up!

When I was in first year University (age 17), I was used as a guinea pig in an
experiment that involved running on a treadmill.  The students stopped me
when I hit 225 -- I was unable to convince them I was still fine!  I don't
remember even feeling close to the limit then.


 
 
 

Swim vs. Bike/Run Heart Rates?

I have recently used my water-proof Heart Rate Monitor to measure my
Hearty Rate during a hard run and a hard swim.

Just over a week ago, I wore it for a tough, hot, hilly 15k road race.
I ran most of the race at 175-180 and in the last 300-400 metres sprinted
and pushed it to 202.

This morning, I used it in the pool during 2 broken 900 metre Long Course
sets. Set was 2 x (400-400-100). I swam the 400s at a rate of 160 in times
of 5:16-5:22. I swam the 100s at a sprint pace of 1:09-1:12 and my heart rate
at the end of the 100s were 181/182.

I find in the pool my heart rate recovers very quickly compared to running
outside on a hot humid day. This combined with the overall lower heart rate,
and my physical feeling at the end of races of different sports makes me
think the lower heart rate has a lot to do with cooling effectiveness of
your environment.

I also believe heart rates have a lot to do with other things:

   1)How efficiently you perform the sport
       - I am not nearly as strong as other swimmers that I can beat
         it is my technique and efficiency
       - my running technique is much poorer than many fellow runners
           and I have to work harder at it

   2)How strong are the sport specific muscles compared to your overall
     aerobic fitness.
       - climbing a steep hill for 10 minutes on my bike can not get the
         heart rate over 165.  My legs feel like they will blow up long
         before I get the heart rate any higher.  I am (compared to
         running & Swimming) weak on the bike.
