I call it the resting phase, while you call it the power phase. Why 
would I be wrong, and not you? Tradition is not a valid argument.

The energy to change sides amount to about 30 Nm in my case: I lift over 
3 kilograms about 1 meter in the air. If I do that every second, I put 
about 30 Watts into just lifing my arms. If that efficiently converts to 
forward power, I should give a kayak a speed of about 2.5 miles per hour 
(which is just below my normal touring speed), if the measurements from 
this site are correct:
