VO2 12s #4

Did the VO2 12s again. My fourth time doing these. They didn’t feel so bad at all – I actually quite enjoyed them. Time has come to do something about the resistance on the rollers. I’m reaching the upper limit of what I can do with them. I need to find a shop that sells belts, pulleys and drives so I can rig a resistance unit onto them.


Today’s VO2 Max session:
467kJ, av. 235W, NP 256W, TSS 56,5

Previous sessions:
469kJ, av. 240 W, NP 257 W, TSS 56,1
474kJ, av. 239 W, NP 258 W, TSS 57,2
439kJ, av. 222 W, NP 240W, TSS 54,0

There is more to it than the figures show. I’m quite sure I hit the 30s harder this week, so let’s analyse each nine minute segment:
1: 142kJ, av 264W, NP 270W, TSS 16,4
2: 140kJ, av 261W, NP 268W, TSS 16,1
3: 140kJ, av 261W, NP 269W, TSS 16,2

And comparing to the last set I did:
1: 141kJ, av 261W, NP 268W, TSS 16,2
2: 139kJ, av 257W, NP 265W, TSS 15,8
3: 138kJ, av 257W, NP 265W, TSS 15,7

So I was correct! Today’s was an increase in performance. Small, needed an awful lot of analysis to show it, but it was there.
