1.5 W / kg se povazuje za aerobni prah pri testovani kardiaku
80% toho prahu se da udrzet mnoho hodin

http://en.wikipedia.org/wiki/Bicycle_performance pise:

Amateur bicycle racers can typically produce 3 watts/kg for more than an 
hour (e.g., around 210 watts for a 70 kg rider), with top amateurs producing 
5 W/kg and elite athletes achieving 6 W/kg for similar lengths of time. 
Elite track sprinters are able to attain an instantaneous maximum output of 
around 2,000 watts, or in excess of 25 W/kg; elite road cyclists may produce 
1,600 to 1,700 watts as an instantaneous maximum in their burst to the 
finish line at the end of a five-hour long road race. Even at moderate 
speeds, most power is spent in overcoming aerodynamic drag, which increases 
with the square of speed.

nevybirali pro to letadlo nejakeho 40kg strizlika ?
