Heartrate Question

good question Dcoughlan, my heart rates are always high in january even though right now im doing 100 mpw

it must be because it is cold, i'm not sweating much and so my blood volume has dropped.

blood volume is more water (plasma) than blood cells, so in summer, my blood volume is higher.

in fact, if i went to Miami to train, within hours my blood volume would rise as i would have to drink more water to cope with the warmer weather. my resting heart rate would drop from 46 to 38 and all my training heart rates would fall too.

is it cold where you are?

California so not really.. in the 40s.

same here in England, in the 40's we dont have much cold weather, very rarely below freezing in the day.

just cool weather mostly 35-55

temps in the 40s are cool enough to substantially lower my blood volume and raise my heart rate.

this is normal, i am running very well in all my workouts.

I ran 1:49/3:42 and had similar heart rates for similar efforts while teammates would be at 10-20 beats /min less.

My effort seemed the same, my heart just beat faster.

I think they are guidelines that can be kept on a sliding curve.

I have medium heart rates...75-80% is about 160 and my max is about 200. Anyhow, I'm working with a guy who was a good MD runner whose easy days (75-80%) are between 165 and 175. Being a MD guy generally means your AT is higher so you can train at higher heart rates than LD counterparts. Don't worry about it. Take your heart rate in the morning just to be sure it's not rising.

That does not make sense.

1) higher tolerance for accumulation of lactic acid (while staying below the anaerobic threshold) allows MD guys to run faster without tying up. They just can't go as long.

2) MD guys usually have higher resting heart rates...if he's using that as a guideline (don't know, just guessing) then there's naturally going to be a gap there.

Dcoughlan,

What is your Max HR? If it is 210+, your training heart rates wouldn't seem all that out of whack.

Have you read the Hadd thread from awhile back?

It's changed my life. I was always training at too

high a heartrate. Now I run twice as many miles as

I did before, with no hint of injury (I always had

IT band problems before), and I'm getting faster!

I'm expecting some big PRs later this spring!
