Maximum heart rate varies quite a bit from individual to individual and it does not have anything to do with how well conditioned one is.
As for the comment by Freddy Boy on "help me with my sprinting on the bike". Well, Freddy, you messed up and chose the wrong parents. Sprinting is related to the proportion of your muscle fibers that are "quick twitch" and that is genetic. One can not train to become a great sprinter. Sprinters are born. Sure great sprinters have to train but they can not train to be great. You either have a great sprint or you don't.
