power weight ratio
 

whats a good max power for someone weighing 155 lbs?

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

thanks cliche, i think were the only ones up. since ur the only one to answer both my post

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.

well i did a vq training session and i did a 30 sec all out effort and got just under 1000 watts.

What's a vq?

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

Poifick! Cheers WR :)

I'm at the top of the 'untrained' category on that w/kg list :(

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.

vq is robbie ventura's coaching thing. theres one here in orlando, chicago and one being built somewhere out west. the "just under a 1000 watts was peak power.

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.

what data do i need then?

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..

My best 5s is also 94% of my peak

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

my 5s max is 94.83163665% of my peak, approximately.

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