It was freezing this morning. About 28F, so I decided to erg instead of rowing outside.
Plan called for steady state. So…
- 4 x 20’/1′
- ramp pace over first 10 minutes (5′ @ 2:15, 5′ @ 2:10, then 2:04 the rest of the way)
- lactate test at 60 minutes.
So, in a nutshell, here is a real life example of how uncorrelated HR and lactate can be under different circumstances.
So compare yesterday and today. power within 2 watts. Same exact warmup process. Lactate reading was 0.3 higher today, but HR was 16 beats higher. Thats more than 12% of HRR different.
I was in a different place, at a different time of day, and the room was definitely a bit warmer. I had good airflow in both cases.
The conclusion that I am drawing is that I will continue to use 60′ lactate readings as a measure of intensity. 2.3 is above the high end of what I really want to see, but I don’t want to change training intensity based on a single reading above the limit. So, I think I will hold at 185W, and continue to test. If I read above 2.0 for the next workout, then I will drop 5W.
Tomorrow: Back on the water for a 5x2K / 5′ rest at head race pace and r28.
