Sports science is this sort of generic name for all the sciences that attach themselves to sports, So, within sports science we have sub-categories such as psychology, sports coaching and sports injuries there are also various other sub-categories such as nutrition. And really what we're trying to do in sports science is to use what we know about the body, about the brain, about the way that we learn, in order to give athletes the best advantage possible, so that they can perform at their best. I also study performance analysis, which is really the science behind analyzing team players and individual performance; and looking at how it's been performed, measuring the performance and then making adjustments to the performance, to get athlete to perform better. So, we can look at tactical play or we can look at individual performances. So, we could look at someone's golf swing for instance, and measure the speed of the club head and determine whether or not the muscles are being used efficiently. Or we could look at a football team scoring a goal and see how it was done, in order to try to do it this way more often.
