I was diagnosed with Grave's disease last fall. I caught it very early when I noticed that my average heart rate began to climb and lost a bunch of weight. I am on PTU and have slid into a hyporthyroid state and so have cut way back on my meds. Even now my resting heart rate is 10-15 BPM higher than before my illness. This complicates figuring out my training zones for my first ironman. So, using common sense and RPE I have just rejiggered my zones up 10 BPM. My coach is planning on doing lactate levels within the next month. Any thoughts on this Juareg, as I heard you had the same thing?

Thanks for your question and " welcome in the club."
First of all can you give me your TSH free T3 and free T4 values prior to the PTU and the latest lab results now.
Second " do you check HRV ( heart rate variability ) in your training.
3. Lactate values may help if you use lactate as a trend information ( see FaCT system )
If you use it as a traditional system with 2 and 4 mmol , but certainly if you look for the system , where the check for the increase of more than 1 mmol/L lactate step you may be up for some surprises.
HR , HRV and lactate values seem to change dramatically with the potency of T3 lavels.
T3 on the other hand seems to be influenced very strong by hypoxy training , as well some other training variables.
I am in the office for the moment , but will take some time over the next few days to give you some back ground on thyroid hormone reaction I collected over the last 2 years, and as you will see it is very interesting.
So will be back here in the evening with a short start on this particular matter.

Thanks Juerg! I will have my tests for you tomorrow.
I guess I am ignorant of HRV. I do wear a HR monitor and watch what zone I am in.

HRV -heart rate variability.
It seems , that if your "system " is running more on sympathetic activity ( work exercising , adrenaline , epinephrine a.s.o your HRV will drop ) if you run more on a vagal situation ( sleep , relalaxed , good recovered you have a much higher HRV.
Now interesting is that if you have a release of T3 ( resp. conversion of T4 to T3 you will see a rise in HRV. This is very easy to track down for me as I am on a dosage of T4 and T3 , because my thyroid don't function anymore . ( Radio treatment to treat a severe Graves disease ) result of this treament is often a hy[pothyroid situation, which I have or had.
Now interesting is the HRV in tracking down the half value time of T# which will help to time dthe intake of this hormone much better , than the classical way of just taking it.
You can track on 1 - 2 hours exactly the most effectivness on this hormon and therefor can plan your most active time in the day, or better sleeping pattern in the night.
The variation on HR is very clear : up to 10 - 15 beats , depending on the timing , which in my case at least also reflects in actuall perfromance and bodyfeeling.
It as well may reflect on release on other hormons like HGH and testosteron.
This leads to an interesting hypothtical point in the latest drama on the tour de France.
Landis - has a thyroid problem , takes most likely thyroid medication which will alter a lot of different hormon parameters in his body. Take a combination of dehydration the day before ( bad race ) combined with the frustration ( race tour is over ) and some alcohol ( see altitude and dehydration ) influence of alcohlo to altitude and dehydration .
following by a body reaction of rehydration and changes in parameters like blood values as well as some hormonal reaction and you may very likely be out of the " normal " range of blood values.
Taking the fact that he was drinking water like crazy in his " famous " stage win you sometimes wonder , that any of this guys are even close to " normal " levels at all.
This just a thought, purely based on performnace drifts I can see and produce with my own body due to the fact that I take T4? T3 in a very "controlled way." I decide the timing and not my body with a biological release . So as promised I will be back with some more "questions " infos about this particular very interesting topic .

Juerg, I would love your input on this if you could. Thanks!
