no when it comes to fighting with weapons whatever weapon or style you use, as soon as a weapon is involved it isn't a sport at least not internationally, some countries do have sports that involve weapons. For instance kendo is considered a sport in several countries but not  internationally since the practice sword is still a sword. Brook must be able to do at least some martial arts, but so far we haven't seen him do so. (any swordfighter must have least have some martial arts basis to be able to handle a sword).
