    Consult the e-wang chart courtesy of Coggan et al.

    Just curious, what do you mean by "max power?"

    For common durations Coggan's chart above is a reasonable yard stick, especially when comparing to your own history.

    What is the best way to determine FT? I think that I am off the bottom of the chart!

    not sure what you're trying to say here.

    was the "just under 1000W" a peak power or was it your avg. power for the 30"? if it was your avg. for the 30" then you're either a world class professional or have a calibration issue with your watt-o-meter.

    This last season my best 5sec power was 926. I weigh in the low 140s and I think I am a poor sprinter. But other than going for sprints in group rides I don't do any training for short term power. If I worked on it more I could improve it.

    Unless your sprint is uphill, power/weight is less important than just plain power.

    You really don't have enough information for any sort of assessment.

    Well, if you want to see a profile that would fit into a chart like the one above, then you'd want to get a series of mean-maximal power tests done. The common ones for the profile above would be 5s, 1m, 5m, and FTP. There are several ways of estimating FTP w/in 10W without actually doing an hour long TT. These tests would have to be done when you're well rested and healthy, and they need to be truly maximal efforts -- no way you could have possibly gone harder.

    I had a performance assessment done earlier this year. It was a 48th b-day present and I figured it would give me a good baseline after a year of cycling (after about 17 years off the bike). They used the terms VT1 and VT2, with VT1 being the lactate threshold (64% of VO2 max) and VT2 being the "'onset of blood lactate accumulation" (86% of V02 max) - which by their description seems equivalent to FT. The VT2 (OBLA) is defined as the point where the increase in blood lactate can no longer achieve a prolonged steady state.

    So does this sound like VT2 is FT? Based on heart rate it is right in my TT and hill climb zone, but I am nomenclature confused!

    Is that ventilatory threshold? I don't know much about the implications in that area. If the HR lines up though, then it's probably about right. Power is a good way to view it though, as you can train to produce much more power at a given HR, but just using an HRM won't allow you to measure the gains.

    Good question - and I think the answer is yes, defining two threshold states. What I had for numbers is:

    V02 Max: 68.5
    Vt2 (which I think is FT): 290 watts, 4.3 w/kg
    VT1: 220 watts, 3.2 w/kg (this was at an HR of 161 which is about top of zone 3 for me)

    thanks for the assist in understanding these. The watts per kg seem better than I'd have thought but the effort/HR puts it where I would expect.

    Taylor Phinney has a max power of 1800 watts and he's 180 lbs. The 5s sprint isn't far from that. I'd say: multiply your peak by 96% to get your 5s power or divide your 5s power by 96% to get max power.

    FWIW, my best 5s power last season is 94% of my peak power.

    96% definitely sounds high for most (non track) riders..

    I just calculated out that my 5s is about 93% of my peak

    Heh, mine was a little over 94% too. Interesting.
