But, HR can change based on variables, but that doesn't mean you are in any worse shape that day. I've had my HR show higher than usual during threshold intervals, but felt fine and ignored it. When I tested my lactate it was between 3 and 3.5 (which was the plan). If I had followed my HR I would have run too slow, and because of some silly variable that didn't really affect my shape that day.
If your threshold pace is 3.10, if thats a normal day you'll try running at that pace, and neither Lactate or HR can tell you that is too fast or too slow before halfway unto your intervals. You dont get to LT HR in the first interval. So lets say its a really hot day and because of the heat 3.10 is harder than usual. Then I'll simply adjust my pace, either by feel or by testing my lactate halfway. In my experience I won't get to LT HR before at least halfway, so how does that help me any more than lactate testing?
"But if you follow the pace control on the the 85% HR zone you got to be for sure that you are running at your LT pace"
You won't run at 85% in the first few intervals, they will always feel sort of fresh anyways. Anyway, when you train with lactate for a while, you develop the ability to know what lactate you currently have, there is no way I will get 5 mmol if the goal is 3. If I did I would feel it in my breath and legs, easily.
No, you should take it within 40-60 seconds as the lactate starts dropping after that, or if a really hard workout after 60 seconds. One thing that HR cannot do is when you have an all out workout, you would want to know how much lactate you are able to produce. If you get 14mmol, you'll know theres more work thats needed to be done. Lactate is energy and so getting 17mmol on that day would be better, HR could never tell you this, right?
Other than that, yes I agree, you don't necessarly need a lactate meter, its expensive and HR work just fine, but if you have one I think its a useful way to really measure how hard you are training and how your lactate production is etc.
I don't trust lactate because of propaganda/advertising. I've never seen a lactate commercial my entire life. The reason is because good runners use them as a tool to improve. For example: Marius Bakked (13.06) and Henrik Ingebrigtsen (5th in the 1500m final in London) + more
You see my problem? First you have great runners that use the lactate meter a lot to improve, and feels that lactate is very important in your training, then a guy like you says its not important and that HR is better. Its confusing. But really, its not what I'm most curious about. I'm more curious about correct 800m training.
Canova says: 800m aerobic support is between 8-12mmol. But if you dont test your lactate, how do you know if you are in the right intensity? What is 8-12 in mmol?
Whats the difference between threshold intervals and pure steady state aerobic training? I would love if you were able to talk more about this last part, didn't quite understand everything.
a. Pulsen kan helt klart si noe om dagsformen, særlig hvilepuls. Men terskel er laktat på ca. 3,0 uansett om dagsformpulsen viser 150 eller 180. Det hjelper lite å holde bom fast på 170 i puls hvis dette betyr 5,0 i laktat fordi man på denne gitte dagen har terskelpuls på 150. Eller motsatt, ligge på 2,0 i laktat og 170 i puls når dagsformen tilsier at man kunne ha hatt 180 i puls og 3,0 i laktat.
