Exercise load query

Actually, this time i used my Waho TickrX HR chest belt :) 

So what now?

And btw, i am wondering about the exercise load you get. I did only get close to such high EL numbers on really hard 3-4h cylcing rides with quite some climbing... using a chest strap.

Something is off here

So let me show you another example, closer to your workout:

10x3min at 28spm and quite max tempo... almost no anaerobic effect and only 96 EL. How come?

I am completely dead after that, but my HR does barely go beyond 150bpm. When going for a run or cycling I am always immediately close to 145-150 and never feel so destroyed. What is wrong here? Neither the wrist HRM nor the Chest belt bring realistic HR data... I do not get it

It is perfectly normal that you register very little anaerobic benefit because you have spent little to no time above your lactate threshold.

You said earlier that your MaxHR is about 175, so same as mine. Therefore, your lactate threshold - if you leave it to its default value, should be around 155  correct ? Check your watch. You cannot expect meaningful anaerobic benefit if you spend no time above your lactate threshold (shows a max HR of 153). In fact, what surprises me, is that you even got 0.6 in this session ! You deserved none  !

Your HR record above looks MUCH BETTER than the one you posted earlier today, and indeed looks like it's been recorded with a proper chest strap. The one you posted earlier, I'm sorry, but it doesn't look right to me. The shape of your HR log doesn't look like it's been done with a chest strap. You can see it for yourself, it's not smooth. It's spiky everywhere.

How is it possible, that i wrench the last bit of energy out of my body while rowing... and get 155bpm... and while running or cycling I get easily to 165bpm and do not feel so destroyed at all? 

Ok so for this, I don't know. I am not particularly fit, we're about the same age and my VO2Max is 44 only. But I can do a steady rowing session at 160bpm without issue. I will be tired after, but I won't be wrenched.

Let me post a few example of my rows, perhaps you can find something useful. Both steady sessions, one to improve my VO2Max (so rowing at 160bpm, so above my lactate threshold, and note the 0.9 anaerobic benefit), the other to improve my aerobic base (so rowing at 130bpm).

Thx

How do you get 84 intensity minutes out of a 45min row @130bpm but only 57IM out of a 30min @160bpm row?

I find most of these garmin calculations quite confusing

Because heart rates of 130 and 160 both  belong to the same category of "Vigorous" as per Garmin's metrics.

(I personnally don't pay attention to these intensity minutes, it's too imprecise to mean anything to me).

You have 130 as vigorous? My vigorous minutes start at 143bpm. I find that all very confusing and close to frustrating. Maybe I should stop working out with a Garmin completely and just enjoy the workout itself for what it is without all this fuzz

I think you're confusing the way Intensity Minutes are calculated with the heart rate zones.

Heart Rate zones are calculated as % of MaxHR (90, 80, 70 etc), unless you override this obviously.

For the Intensity Minutes, you only have 2 categories: Moderate and Vigorous (that's it) and I don't think there is a direct equivalency with the HR zones. Garmin unfortunately doesn't explain precisely what the threshold is for a minute to qualify as Vigorous. HR obviously is going to matter but they say other parameters (age, sex, resting HR, weight, height and probably a few others I forget) are used. Just because your Zone 4 starts at 143 (is it what you were trying to say ?) doesn't mean this is where minutes become Vigorous.

I agree with you, a lot of this stuff isn't particularly useful.
