I do not think so, but apparently it is.
sport /sp?rt, spo?rt/ [spawrt, spohrt]
–noun 1. an athletic activity requiring skill or physical prowess and often of a competitive nature, as racing, baseball, tennis, golf, bowling, wrestling, boxing, hunting, fishing, etc.
In my opinion a sport must be of a competitive nature, but I am disagreeing with the definition in a way.
