Indeed.
That's why Mike doesn't row at a higher rate.
I am not saying that Mike _should_ row at a higher rate for 5K.
I am saying that he can't.
If he could, holding his technique steady, and therefore suffering the additional muscle fatigue and aerobic stress, he would be faster.
But he can't.
Holding his technique together, he can't row 5K at a higher rate on the erg, either.
That's why he pulls 5K on the erg in 1:48 rather than 1:38.
That Mike can't rate higher (and therefore go faster), either OTW or on the erg, doesn't mean that someone else his age and weight can't.
To do so, they just have to have more physical capacity, comparable to a younger rower.
Clearly, Mike's 5K on the erg shows that his physical capacity is severely limited.
The problem, I think, is his maxHR.
On the erg, Mike and I row the same rates and paces with the same HRs.
But I couldn't row 5K at 1:38 if I had a max HR of 163 bpm, either.
But for me, 163 bpm is just middlin' UT1.
AT for MIke is probably about 155 bpm.
For me, AT is 180 bpm.
My HR is around 155 bpm when I am pulling 1:48, too.
But I won't row 5K with a HR of 155 bpm.
I can row a FM with a HR of 155 bpm.
I'll row a 5K with a HR of 180 bpm.
