Targeted Watt / KG according to 4 & 20 min best

[VS1]

Hi,​

If I have recorded average wattage for 4 minutes, for 20 minutes and for 30 minutes - is there a way to calculate / predict what should be my best average power for 1 min, 5 sec. And other durations ?​

Thanks.​

Not for times that short/that much shorter than your test durations. However, if you plot the work you performed in 4, 20, and 30 min against time, you should get a straight line that would allow you to estimate your power from, say, 3 min to 40-60 min with reasonable accuracy.

Thank you! if I understand correctly you mean that it is pretty much linear but not for.. say.. 5 sec and 10 sec all outs..

The model works well up to maximal aerobic power riding and allows for a component of anaerobic capacity but once you get into sprinting, that's using different physiological capabilities - i.e. your neuromuscular abilities.
