Freiburg model of lactate measurement

Recently I did a test on an ergocycle to determine lactic acid conc. at various increasing loads. Started at 160 watts and 4.5 minutes later blood was taken, and after 5 min the second interval, this time at 200 watts was started - again 4.5 min, take blood. This was repeated using the same 40 watt increments until I got to 360 watts where I failed after 3.5 minutes.

So is 360 watts my MAP? I'm 63-64 kilos and a slightly better than average rider so perhaps this makes sense, but then I read about other methods where the load increase is different; i.e. 20 watts per minute and wonder if this were the case could I have tolerated 2 minutes at say 380W after 2 minutes at 320W and 360W instead of double the length of time.......

Comments and experiences are welcome!

360 W isn't your MAP when using my schema or British Cycling's methodology. For us we use 20 W/min (on a continually increasing load) for elite males or 25 W/min for non-elite males. 15 W/min for women.

With the continually increasing load we increase ours 5 W/12 secs, and it doesn't matter if you finish a complete minute (at the end) or not. we just calculate the MAP as the best 60-secs.

thanks Ric. That's interesting, I do know from the test which power corresponds to a 4mmol lactic acid conc, and the diversion in the curve signifying LT. Is it possible to (gu)estimate FT from 4mmol power?
