Lactate Threshold Power Duration

[hjs]

Ah, I thought you talked about your current form, what you once did is ofcourse not relevant now. Put some recent results in that predictor yes.

I did 5000m yesterday, 23min 03sec / 132 watts. My best so far. Wasn't a full on test.

A few days ago I did a full on 60 minute test after a rest day and only managed 108 watts. This puts my 60 minute power way short of what any predictions says it should be.

This puts my Functional Threshold power (60 min power) at only 82% of my 5,000m (23 min power).

Don,t overthink it. You have plenty of room for improvements. Focus on that, testing again and again is not needed. A real full 60 min is really tough. Not something to do often.

Why is my 60 minute power so poor compared to my 60 second power?

60 seconds, fitness plays not such a big role, base strenght does.

60 min, aerobic fitness is most important. Answer, you are not very fit. And not just relative but also absolute. Don,t know your stats, but even the 60 second test is not outstanding.

I know I'm not fit.

I'm 57, 5'7" and 14st 5lbs.

Age 41 I did 2000m in 7min 15sec 270 watts and 5000m in 19min 19 sec av 225 watts as a Lightweight.

I know the 60 second test isn't outstanding, I know it's crap and I'm embarrassed by how crap it is but the 60 min power is even more crap.

Found old note book, edited 2000m time above. 500m age 41 was 1:38 372 watts.

Looking at Murray's records for 5000m 10000m and 60 minutes his FTP is nearer 87% to 90% of a 20 minute duration.

Might a rowers FTP be consistently a lower percentage of shorter distances / durations than a cyclists?

If you take Greg above his FTP is only 83% of his 5000m average power.

Daniel above has FTP at 86% of his 5000m power.

I think there is no alternative other than to do a full 60 minute test. Probably why The New Zealanders do this. Rowers with a similar 2000m & 5000m power may have vastly different 60 minute power.

Looking at the small sample above, rowers FTP is a lower percentage of shorter durations than cyclists.

Is there any published data on rowers power curves?

Taking Daniel and Gregs 6000m power compared to their 60 min power.

Daniel's 60 min power is 87.2% of his 6000m power
Greg's 60min power is 84.4% of his 6000m power

A hypothetical rower with a 2000m power of 400 watts would average 340 watts for 6000m and 304 watts for 60 minutes.

That works out at 60 minute power being only 89.4% 6000m power. Cyclists have a higher FTP in relation to their 20 minute power.

I'm still improving quite rapidly, and I haven't done the hour test in a few months, so my current posted numbers aren't great for this kind of study. If I make a PB attempt right now, as long as I've prepared properly, it'll come.

I guess for 5k now I could probably go 1:57/500 (218.5 watts), the 6k @ about 1:58/500 (213 watts) and the hour @ 2:01.5-2:02 (195.1-192.7 watts).

So my 60' wattage is probably about 91% of 6k wattage, and 89% of 5k wattage (and about 72% of my 2k wattage from my recent PB, but then I could probably edge another couple of seconds out of that 2k now too).


I wonder how this will evolve this year. I am getting stronger In May my favourite 137.5m pool opens for the summer and I'll be using that a lot for extended periods, along with the rowing, the weight training etc.

According to the link my 2000m power would be 60 sec power divided by 1.53.

I did 350 watts for 60 seconds which would predict I would do 228 watts for 2000m.
And 1.1764 times my 6k power would be only 172 watts for 2000m.

I'm clearly aerobically challenged.

Today I was feeling tired and weak in the legs from yesterday - 10,000m av 126 watts.

60sec av 345 watts
60sec av 350 watts
500m av 226 watts
