G'day Matt,

Thanks for the power information and for making the point about arm weight.
Taking that point further it would seem appropriate to treat the arm and
paddle combination as three segments: i) paddle ii) forearm and hand iii)
upper arm, because each segment's centre of mass will have a different
vertical displacement when a paddle blade is raised, at least in my paddle
stroke. The cadaver paper has the arm segment values so I'll recalculate the
potential energy for lifting each segment at the weekend.

All the best, Peter
