Need Help for Unicycle Documentary!!!

Hey me and a friend are currently working on a documentary on another friend who will be unicycling 100 miles for charity. We have been looking for charts that display how a unicycle effects your body such as strain on the muscles but have not been sucessful. Does anyone know where we could possibly find a chart like this or statistics. Also we would like to compare a unicycle to bicycling or other physical activities and how they differ in terms of muscle strains. Please Help with any links

As far as I know there are no such charts. :confused:
