Hi Folks,

I've just started intervals and I'm able to output 250watts at 80% of my max hr.

What can you folks do in terms of output @ 80%

Power output is not generally quoted as a percentage of heart rate, as under conditions of constant heart rate power declines.

Power is generally quoted in terms of duration: 1 minute, 5 minute, 20 minute, 1 hour. In addtion, absolute power is generally not quoted, rather watts/kilogram. 250 watts is not very much if you are 150 kg. It is if you are 50 kg.

Stop looking at your heart rate...

ok... maybe by 80%, he means his LT HR?

In anycase... John is correct... the only really important value is your power to weight ratio as a function of time.

If you want to know where you stand in the grand scheme of things... find your LT power and compare this to this chart.

http://www.t2r.org/train/powerprofiling.htm

I find this chart to be a little on the low side. I'd add 0.2 to 0.3 to the 20 min times. This chart might be dated, and the power outputs of all catagories have gone up over the years.

true...........

I can produce more then 800watt with a heartrate under 140 for 1 second.

I cant produce more then 600watt with a heartrate under 140 for 1 min!

do you understand?

When you do a med test you can work out how many watts you produce at 80%. Its hard to relate Watts with heart rate because you can lose form. Heartrate will change when form is different.

Eg, when you are fit and have good form a rider can ride 300watts@150HR, but when the rider has no form, he might have trouble riding 300watt@175HR.

I think you just got a power monitor on you bike, if so you will learn so much from training. How to save power in races and how to use it at the right moments. You will also train smarter! if this is right, have fun!

I guess he is referring to his maximum aerobic power, mine is ~360W/ 162bpm (195 max) at 72 kg. Maximum power is ~420W over 3 mins (socalled "Freiburger Staffel", starting at 100W with 20W steps every 3 mins).

Dr.Dos, You're quite correct.. thank you.

Last time that I was tested, it was 77% (base level sift) 254W,91% 380W (anaerobic level sift) ,444W max on 3 minute steps on ergo test with oxygen analyzer. It was like 2 years ago.

I have not done a controlled test in a while but Wednesday I did a ramp test very similar to that prescribed by Ric Stern. What happened is I went out to do a couple 20 minute hill repeats, but from the start I was not feeling weli, I think a bit over overtraining as I had swollen glands. Since I was not able to hold my target power after about a mile into the climb, I decided to drop back the power than slowly ramp up over the remaining length of the climb and use is as a MAP test. The result was a MAP of exactly 400 watts with a peak of 513 watts.

I am afraid to get on a scale for watts/kg...

My maximal aerobic power was 340 watts and 60kg 2 months ago.
Right now i think it's 350 watts and I weight 59kg.

My power in February was 276 watt on mlss. I weight 62,5 kg. Now should my power on mlss be a lot higher, I think I am already above 300. (yes I know that is a lot more, but we changed the way I trained dramaticall)
