G'day, There's an interesting chapter on human power in Wilson's classic book 'Bicycling Science' that covers the human power generation and energy consumption for movements such as cycling and rowing. On the whole the two seem to be comparable despite the very different actions. On a bike 100W seems to be a reasonable cruising power and 200W a decent workout over an hour. Re the horizontal vs. vertical stroke some considerations on classic body types that fit a large proportion of older paddlers: the increased efficiency of a 'horizontal' paddle stroke if the paddler has restricted mobility and relatively high upper body strength compared to abdominal muscle strength the increased efficiency of a 'vertical' paddle stroke if the paddler is flexible with low upper body strength but strong abs. Grand discussion Niels and Matt. Thanks. I'm about to cycle home! All the best, PeterO *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
