Cyclists with a "Running" Problem

[Odinson]

I use LTHR zones amd not the default.

 

Did you do the lab tests to get the LTHR numbers?

Yes, was the Vitality Elite Fitness Assessment (a few years back), and compared it to the finger prick test. There was 1bpm difference, so I took the lower of the two.

Nice, would be an interesting test to do.

Dumb question warning...

 

LTHR will be different for running and cycling right? I have my cycling no's, is there a way I can translate these into running? Formula or something like that

IMO the number will be the same, as the test protocol is the same, at least that’s how Joe Friel and Dr. Andy Coggan explain the LTHR test.

You go as hard as you can for 30 mins. After 10 mins press the lap function, then take the average HR for the final 20 mins. That’s your LTHR. They mention doing the same test for running and cycling. Not 100% accurate but close enough.

 

In the lab test (for VO2max), it’s a ramp test using power. The watts increase on a linear line, eg. 1W every 4 seconds. At the same time, your HR should increase on a similar linear trend. As soon as it spikes that is your crossover point which is the LT value.

 

The blood test will determine the amount of lactic acid in your blood after a series of tests. A medical student did some tests on members from my club as part of their practical work. They told us how to ride, and for how long... which wasn’t lab controlled. I remember the number was close to the lab test results (1bpm).

 

With training, it is possible to increase the LT, but your maxHR is genetic. That’s why I changed to %LTHR as my zones.

My wifes also has a very high HR...imuch higher than mine, even though she is a few years younger.

 

It’s important that you work out your Training HR zones according to your specific running max HR or lactic threshold HR, and not the standard age based calculation.

Women tend to have a higher HR than men and your max HR supposedly slows as you get older so that's spot on.

Yeah sure, but +/- 25 beats higher.... age difference 3 years.

Maybe her HR and moer meter are linked

I'm not too fussed with the exact accuracy of the HR. To be honest, the biggest use I get out of it is monitoring fatigue or oncoming and outgoing sickness, etc. using the resting HR reading. I've found that it's extremely accurate at predicting an oncoming cold and handy for telling me when I can get to running again. I seldom use it on a run but if I do check in I only need to know roughly which zone I'm in (and that I'm not going too fast for the purpose of the run) rather than the exact HR.

How does your check your resting heart rate... Is there an app for that?

[Stretch]

When I do a long tempo run I try keep it below 150.

Good question

I usually try measure it by relaxing horizontal on the couch or bed for about 5 minutes or before I get up in the morning....

 

Now with my polar vantage It gives me my lowest and highest HR for each day, so I wear it when I sleep and check it before getting up. I’m still not convinced that this is accurate..... but I gues the overall trend is more important and if you see a largish increase then you know something is amiss or not recovered.

 

It’s a massive improvement from the good ole days when you had to manually feel and count your pulse rate..... something you laatjies probably never had to experience

I still have a strap... So have in the past manually put my strap on in the morning and monitored the HR... Would be nice to be able to run an app that works out the average over a specified time. Just looked on the store.. Seems there are a couple of apps

LT for running and cycling are generally not interchangeable.

If you have an HR watch with an optical reader, it usually always records your RHR. You need to wear it when you're sleeping to get a good measurement. 

 

Like Barry said, your HRH is a good indicator/predictor of what's going on with your body - stress, sickness, etc.

I’m no medical expert, far from it - so I can only comment on what I see, read and hear.

 

My question is: Lactic acid is produced when the HR exceeds the threshold, so how would one’s body know the difference between one type of workout and another?

 

Edit: let’s ignore conditioning of the person. A fit cyclist doesn’t make him/her a fit runner. It just means the intensity vs duration will differ.

CBlake. Couldn't respond directly to your post....running LTHR and cycling LTHR different across sports.

 

Different sports, difference muscles...
