I’m surprised that inside a gym would be warmer than outdoors in any time outside of Autumn and Winter.

 

anyways, I’m wondering the same as my heart rate at  a given intensity can vary 20-25 beats on a cold vs hot day. What I’ve been doing is still trying to stick to the zone 2 heart rates…. So on hot days I just slow down dramatically. But not sure if that’s what we are supposed to be doing

I think I’m all set. I’m thinking the 3 minute, and even the 1.5 minute break between warmup and workout threw off the test results, so I’m assuming I’m correct in discarding first 5 or 10 minutes

from now on I won’t take a break between warmup and workout aside from restarting treadmill

one thing is certain, I take much longer than 3 minutes for heart rate to stabilize at a given intensity. I think that’s the crux of why I’ve been a bit confused.

Thanks Seth, that is a valuable article. But I’m still a little confused on the question in my last two posts, whether or not the first 5 or 10 minutes after a warmup, upon starting the workout, should be discarded as “bad data”, due to the heart rate drift stabilizing more afterwards for the last 55-60 minutes of a workout.

Here is todays workout, which gives a better indication of what i was talking about in previous post, this time whole workout was above 5%.

Incline: 9% for warmup and workout
Warm up 23 minutes before beginning workout, working up to 3.0 mph workout pace.

65 minute workout (not including 23 minute warmup)
Drift: 150/141=6.39%
Drift discard first 5 minutes: 150/143=4.9%
Drift discard first 10 minutes: 150/144=4.17%
Last 37 minutes of the workout, the avg heart rate stayed constant at 150bpm (150/150=0%)

Thanks. I did another drift test a couple days ago, walking on a treadmill on an incline. I warmed up 20 minutes working up to the steady state speed I used, took a 3 min bathroom break, then began the workout.

 

i think this is my last question? Should I disregard the first 5 or 10 minutes of my workout when determining drift?

this is all after warming up:

-using entire 65 minute workout: 132/126= 4.8%
-discarding first 5 minutes: 132/128 =3.13%

discarding first 10 minutes: 132/129 = 2.32%

 

obviously in this scenario, I’m okay if I don’t do any discarding of the initial few minutes. But in many other workouts, I’d be over the 5% unless I don’t take the first 5 or 10 minutes out of the equation.

Seth, I think I was frustrated and spoke too soon in my post. Sorry. I think it just took 30 min or so during my OP’s walk for the hr to get up to its steady state level, what do you think?

today I tried an actual drift test on a treadmill at a constant speed, walking on an incline. Had jaw surgery a few weeks ago so can’t run yet. Warmed up 15 min, then started the test. Average heart rate of 122 and it actually drifted down in the second half. I found out about the polar beat app’s ability to show avg heart rate over a range, so will start taking advantage of that. It’s probably likely the drift test will correlate with my lactate test heart rates, looking at a couple of my old runs before my surgery, that seems to be the case

[SlowAndSteady]

Too add, on my long runs (an hour and a half ish), once my heart rate gets to the 145-155 range 30-45 minutes in, I can usually keep my pace from then on without my heart rate continuing to increase at a steady rate

[SlowAndSteady]

Thanks very much for the response Seth.

 

i don’t typically track drift carefully since i was so focused on lactate, but i do notice that when i typically started a run at say, 120-125bpm, 30 min in itl be maybe 135-145 (or more if temp is high).

is drift test more accurate than lactate?

 

also, unfortunately nose breathing test has never been accurate for me (i don’t think, correct me if im wrong). My 2.0mmol/l lactate was 30-35 beats lower than my nose breathing when i did the lactate test and remained that way as I improved my 2.0mmol heart rate over time. Even now, I can nose breath at like 160bpm, which is about 80% of my mhr

 

so I think either I’ve been training at too high of a heart rate  at 140-150bpm (based on blood lactate) to make improvements, and need to back down to walking again and use drift test?     Or, I’ve been training at too

low of a heart rate and need to use nose breathing test and run closer to 160bpm

or maybe I should keep using lactate and I’m just not doing enough volume (4-5 hours a week at 140-150bpm for the last 9 months), and that wasn’t enough to make pace improvements from my 13-16 minute miles. Mile pace heavy fluctuation due to temperature

Thanks Adam, I managed to fix it. Quit drinking alcohol (2 months sober now) and have walked about 90% of days the last year. Got a lactate meter, and my lactate at 144bpm is now 1.8mmol/L!!! Now do jogging 4-7/week trying to stay under 135bpm (I feel more comfortable being conservative for now)

[SlowAndSteady]

Scott is right.

 

also, I made huge improvements to my severe aerobic deficiency thru quitting alcohol and just walking every day for multiple months. Like raised my aet ceiling 30bpm

[SlowAndSteady]

Bumping… I hope that’s not frowned upon

[SlowAndSteady]

Scott, I have a theory on why there is the mismatch. I read that alcohol can prevent fat oxidation… and I was drinking too much when I took that test. I wonder if that can explain it?

[SlowAndSteady]

Also Scott… I made a post in the Aerobic Assessment section with my lab result pics…. It said it needed approval before being posted… that was about a month ago I believe. Anything you can do so it will show up?

[SlowAndSteady]

Thanks Scott! Also, in my original post, I meant to say I’ll be increasing allowable hr by 1 beat per week*…. Not month lol. That would take quite a while

[SlowAndSteady]

Above comment I meant to say was not* improving
