I recall there being some debate, many years ago now, over what type of sport was most suitable for nudists taking into account the lack of any protective clothing and the need to involve persons of both sexes. One sport which was devised and introduced into nudist colonies in the UK was a game known as 'miniten'. This was a sort of tennis without racquets and may indeed have been an early form of volleyball. As I recall, miniten never swept the world but it may still survive in some areas.
