In our state, science fair projects cannot use human subjects. You might want to check on that before planning a project. Also, Most of the things being presented here wouldn't qualify as a science project at CP's school or the one where I teach. A good project needs one testable variable and the ability to hold all other factors constant. Scoring is too subjective to make good science and unless athletes are put on the same diet and sleep routine, ect you cannot control for those things either.
