Subject: Heart Rate Zones heat adjusted

Just read a blurb (not long enough to be considered an article) regarding increasing your heart rate zones to account for outside temperatures >72F.

Anyone ever heard of this?  It seems to make sense.

 

Does your heart rate seem to rise when it gets HOTTER?

"In reviewing recent metabolic fitness reports of athletes from Darvin McBrayer, B.Sc, A.P.S, U.S.P.T.A, owner of fitlab.us, his reports states, “As temperature and humidity climb, allow 1 bpm (beat per minute) for every 2-3 degrees above 72 degrees. For example, say your BASE PACE top is 138. At 85 degrees, it’s okay to increase your BASE PACE heart-rate to 143.”

Daren goes on to write, “You will still be metabolically in tune.”

So as the heat climbs and our heart rate increases, we now know it’s okay to adjust our heart rate accordingly!"

It's above 72° here from March through November. I probably should reduce my training zones during the rest of the year.

Cool

I was coming here to post the exact same article! Should we be adjusting our training zones to reflect the heat?

After further thought, maybe I should note the outside temperature during the time of the LT test. 

The last time I did one was in the morning last spring.  ~80ish.

That would make sense if HR was a direct response for training intensity and HR was not affected ONLY by temperature but also by diet, hydration, sleep, stress, fatigue, fitness level, etc.

If you want to adjust your pacing during a race in tough weather conditions IMO do so via RPE primarily and by HR/watts/pace secondarily. Yes you can estimate using the 1 bpm per F degree in temp but you should do so fully aware that others things can also be affecting your HR.

I agree completely with Jorge. I almost train exclusively on RPE during the summer, using the fall and spring to associate RPE with training zones with my HRM and Power Meter. It's an approach to consider, as it will always allow you to deal with extreme conditions and environmental outliers (heat, malfunctioning equipment -HRM or Power Meter, extreme cold, etc).

On the bike, I find that even in 110+ degrees, I can put out a similar effort with a HR elevated by 5-8bpm's over a more moderate day. For runs you need to just take the pace down a bit, RPE will tell you if you are working too hard for the conditions right quick!
