Team sports do not necessarily require a ball for competition. Examples of team sports without a ball include skiing, ultimate Frisbee, dragon boat racing, and synchronized swimming. Skiing involves skiing down a mountain or hill, while ultimate Frisbee requires two teams to compete against each other by throwing and catching a Frisbee disc. Dragon boat racing is a water sport that involves teams of paddlers racing against each other in long boats. Synchronised swimming is a team sport that involves swimmers performing choreographed routines in time with music. All of these team sports are exciting and provide a fun way to stay active.
