Any info I May find useful in a treadmill stress test?

Have to get a treadmill stress test for my job as part of a standard medical screening (FAA pilot physical) The company pays for it but wonder as long as I’m there is there any useful info I might be able to obtain?

For example is it possible to use the data to obtain info such as accurate aerobic or lactate threashold zone limits or any other useful info that could be used later for training?

No. Zero usefulness.

They didn't even let me get to my max hr (which was likely higher than it is on the bike).

I did two in the last six months. It's so unlike anything regarding riding that there's no useful correlation. You're just going steeper and faster every three minutes or so and having your BP/HR monitored. No blood draws, no respiration measurements, etc.

Hot tip. Walk as long as you possibly can, even to the point of awkwardness. Saves your calves and back for a bit longer and might get you to the next level (if you don't ever otherwise run).

Naw. They don't let you do much. They want to compare your results after a set period of effort increases with the study populations in their tables. I was "a fit person of 46" and never even got to a 120 HR. Long ago, my wife wanted to have her MHR tested in a medical setting, just in case, I guess. We were starting to do some harder bike rides and she was a little nervous about the HR numbers she was seeing, like so many folks we see here. They pulled the plug on her when she was still probably 20 beats from MRH. "Not on my watch" they told her.

OTOH, yeah, that was useful information if pumping one's ego counts.

Did they say why they would not let her go to MHR? What did they mean by “not on my watch”?

I just had one early this week. I knew they would not take me to max. They said their goal is to see how my heart behaves (still ticking?) at 131. I'm 65, so based on their equation (no arguing please, I'm just telling what they did) my, let's say population MHR is 155. One common rule of thumb is that LT = 0.8 * MHR = 131, so clearly they had LT in mind. They actually took me up to 153. We would have gone higher but I said "can we stop?" since glute and hamstring pain was significant. It went away quickly, so it must have been lactate, not muscular breakdown.

I would like to find a really good set ofRPE criteria. to see if Ican narrow it down between upper zone 4 and lower zone 5. I certainly had lactate and speech issues, but I was at t two word level and did not really feel out of breath - I breathed hard but did not gasp. I don't want to do the time trial until after my doc explains the results, but I want to just get on nd pedal Z1 and Z2. I can do that now, but I'd like to know if top of Z4 is in the "canonical" 131 range or up near the 150s. Historically my numbers have been higher hr than the standard.

Yes, you can find the threshold point if you have the HR data. But only for running, not cycling.

Because they're different heart rates, running uses more of the body for one. And also we're probably better trained for cycling and more efficient at it.

When I did my stress test a few years ago after a bout of atrial fibrillation a week previous I was told to go as hard/long as possible until I thought I would collapse. Managed to get heart rate to 203bpm after about 15 minutes (age 40) but no AF. I found that It just felt awkward trying to run at the later stages with my hands gripping a pole in front of me instead of swinging naturally like they would when running. I was told this was to lessen the "noise" on the ECG.

Ok in the stress test I felt lactate in the glutes, hamstrings behind the thighs, and calf just below the knee. In cycling I normally feel it in the quads rather than the hamstrings.

​​​​​​Everybody should run a little. It might save your life one day. Unless it's slow zombies, then running isn't even necessary.

If that's the situation, I'm confident I can outrun someone close to me...

Rubiksoval, why did you need two in such rapid succession? I'm guessing I'm rather older than you (65 here), and they're not monitoring me that closely. I am considered to have some risk for heart problems based on family and lifestyle, but I haven't presented with any problems - maybe that's it.

Walk as long as you can: You mean, don't run on the treadmill until you actually must? I think that's what I did - I did not plan to run since my legs, especially knees, are nowhere near in condition for it. In the last two transitions I don't know what the speeds/grades are, but I went from a smooth, fast walk to a shuffle where my legs stayed bent all the time, but it didn't feel like running or like race-walking. I mainly didn't want to go away with my knees feeling beat up, or even being actually beat up. Perhaps I didn't game my stress test optimally!

I had an ablation so that was pre and post op.

Yes, don't run until you must. I went an additional level the second time after walking an extra level. My lower back and ankles were just screaming from not typically running up 10% grades or whatever it was. So the extra few minutea of walking (quickly) helped with that.

The nurse doing the test told me to do that and said it usually helps most people stick it out longer.

Kewl, inside scoop on competitive secrets! Put it on the cover of Bicycling Magazine: "Senior roadies! 5 pro secrets to max out your stress echocardiograms!
It makes perfect sense, I was worried about that same stuff. Yoga has helped me with a lot of little potential joint issues, but I still run into muscles it hasn't
helped me with yet.

Ablation was successful, I presume?
