I think the psychological thing is gonna be really rough on human players, just standing still and watching when you wanna jump up and down in excitement or wave around in horror.
Some ideas include:
Just put up your track kids...
.
Lots of sprints. Calculate the distance between the human player pad and the load zone, and multiply that by too (running back as well). Multiply that distance by say...at most 10 a match (running more than they need to keeps em in shape). Multiply that by the rough number of rounds per day of competition. Your human player should be able to run that distance, with a 5 lb. weight in each hand (equal arm development) very very fast. That's only if you're all hardcore though. The human player does need to be in awesome shape, or else things will be tough for your team.
