FTP

How close to your 5 min power should your FTP be or how big a difference for a trained rider is significant?

The range commonly referred to in trained cyclists to 72% - 77%.  Which is actually quite wide.

 

So, if you do a MAP test (incremental ramp to exhaustion), your pVO2Max (which correlates well with your 5 minute power), your FTP would be somewhere between 72% and 77% of the average power produced in the last 3 minutes of the test (I think it was 3, would have to check that).

bruce, by your calculations......

 

Assume a 5 minutes of 400 watts, that gives a indoor FTP range of 288-308 watts (all indoor) Add 15 % for outdoor (using a median of 300 watts FTP, 75%), one arrives at a FTP of 345? Theoritically of course.....

I would say 3 minutes at 400w.  5min power does correlate well with pVO2Max, but they use 3 min in the MAP test.

 

But yes, sounds reasonable to me because those are similar to my numbers.

OK... thanks. Sorry to sound daft, but if you say 3 minutes at 400w? 1)Does that translate into 5 minutes at a slightly lower figure and 2) should one use a 3 minute 400 watt figure to arrive at an FTP of 345 using the above formulae?

1)  Yes, very much so.  Think about it logically, power is the equivalent of intensity.  If you can handle a certain intensity of a period, then surely you must be able to handle a higher intensity for a shorter period. 

 

2)  I wouldn't recommend that you establish your ftp this way.  What I would say though, if I new an athlete could produce 400w for 3 minutes, is that the athletes ftp is around 340 - 350 watts, and he should aim for that figure when doing a 60min threshold test.  For a 20min threshold test I'd give the rider a target of 345/0.95 which would be 360-365 watts.

You remind me of a certain geek that used to work for me.  Once he asked me my advice as to what to buy his girlfriend for her birthday.  I gave him the name of a new perfume that had just been released - he looked at me as if I was mad and said he was think more along the lines of a new PDA or something.

 

Michelle must be a special lady to put up with your k@k - I suggest you treat her really well, could be a long wait before you find another like her

I dont think that determining your ftp by looking at 3min or 5min power is at all accurate... you get riders who are super strong for 5min and below average in a 30min tt, and vice versa. The best way to determine your ftp is to just do a 30min flat out tt!

Thanks bruce. SRM should be here in a week and then the truth will be told... maybe against fox hill?

Agreed, but it can give you a ballpark figure!

Let's see, Mclean, Beneke x 2, van Biljoen, Harvey, Green, Ryder, Moolman, van Eeden, Labuschagne x 2, etc etc etc

 

We are going to have to hit new bests on our Maximum Power Curve just to hang in there!

 

Can't wait!

How does a sprinters FTP like Robbie Hunter compare to a guy like Rasmussen?

[Imtb]

I don't mean those specific riders but in general the FTP of a sprinter compared to a climber.

This should answer your question far better than I can:

I love her lots and she knows it... Pull her leg all the time so she understands me... I must say she's my everything and diamonds/flowers/25 years subscription to Heat magazine won't be enough...anyway,

 

I wonder if I should call her in from outside... She's washing my bike from todays session... Nah, I'll wait another 30 minutes, The chain must be clean clean for sweet shifting...
