Judging heartrate under the influence of MPH HCl

Training
1

Hi, I have a prescription for MPH HCl to help me deal with my ADHD. I’m experiencing very little side effects and it helped me a lot.
What I’ve noticed though is a slight increase, about 5bpm, in resting heartrate. That’s to be expected.
I’ve also noticed that, in training, my heartrate has been slightly elevated and it’s much easier for me to reach a higher heartrate and stay in that zone. My max heartrate however did not increase.

This has lead to my LTHR being pretty much the same as 95% of my maxHR.

Now I’m wondering if this has ramifications for judging HR zones/response when analysing interval sessions. Has anyone got some experience with this or some medical/scientific insight? Or am I just over thinking here and the models are just as applicable?

First of all congrats on that.

Models are just that, models. If you care about the accuracy of your zones, you should go for a lab test. They will be able to give you personalised zone recommendations based on your actual body.

There is some research on this though: ADHD Prescription Medications and Their Effect on Athletic Performance: A Systematic Review and Meta-analysis - PMC
