Heart rate based training w/Polar H10

General discussion on Training. How to get better on your erg, how to use your erg to get better at another sport, or anything else about improving your abilities.

It is, to the best of my knowledge. Let me explain. One month ago I had a medical sports checkup that includes a test on a bike ergometer. The resistance increases linearly with time at a rate of 35W/min. You are asked keep your pedalling cadence between 90-100 rpm. The moment you can no longer keep up is recorded. I had to give up at 336W @ 160 bpm. So the total test takes 9 -10 minutes, but most of it is in zones 1-4. My guess is that only a few minutes are in zone 5. I don't have a HR record of that test, just the peak values.

From rowing I know that you have to watch the HR very carefully and adjust the 500m-split time so that the HR doesn't rise too fast. I know from the past that for a 10K run, I can do about half of the time in the 90-100% zone without an increase in 500m splits.
Here are the 2K splits registered by the PM3 for this run: 8:57.5 (135 bpm) - 8:55.5 (138) - 8.55.0 (146) - 8:54.3 (149) - 8:52.7 (152).

interesting. i guess that's just individual variation then. because if i thin kback, the last time i did that amount of time IN heart rate zone 5 was a cycling time trial (with 26 minutes in zone 5, heart rate rose to just a beat or two shy of max, at 198) and afterwards i was cooked. there is absolutely no way i was gonna be able to do that again the next day.

I doubt that this test will bring your HR to max. Usually, you need a longer, rather hard effort to bring your HR to max.

As an example, I can use my own PBs:
  • 6 km, 24:09, 193 BPM max.
  • 2 km, 7:34, 180 BPM max.

Not the next day, but after 2 days :

Up to 4K my effort was very similar to before-yesterday, but then I gave it a boost so that the HR shot into the red. However, beyond 95% (152 bpm) I could barely maintain pace and the last 1K was a struggle. Although the total time is slightly better than my last, the 2K splits are very uneven: 8:58.4 (134) - 8:55.9 (141) - 8:50.6 (149) - 8:50.1 (154) - 8:55.1 (156)
It shows that for me 95% is a serious limit. The maximum was 157 bpm. Getting to 160 was impossible.

The difference is that in rowing a certain distance you measure your effort to finish that distance.
A comparable rowing test would be to start at, say, 100W and at every stroke (±2.5 sec) you increase your power by 1W until you are spent.

I am very well aware that my examples weren't ramp tests like yours.

But the fact that your test is a ramp test doesn't really solve the problem I pointed out:
That 9 minutes is too short time to build your heart rate up to max., no matter which test protocol you follow.
