Hello gentlemen,
Thank you very much for your immediate reply.
As Eddie-san pointed out, I should have tested also in rollerski (I will) and even in walking uphill.
Scott-san you don’t have to be sorry. You give me enough comment.
It should be the case that I have been producing not small lactate in rollerski, but as you wonder the shifted amount is rather significant. I am a “sugar burner”.
I will study about the drift test, but I can’t abandon the analyzer yet which I bought in March this year. And,,, Uphillathlete.com is the one who made me invest!
I think I still have some time to cure before we have snow.
Best regards,
Masaaki Ishitsuka
