At the Olympic Games, aquatics means the water sports: swimming in a pool, diving from a board, water polo (the ball game in the pool), artistic swimming (the one that used to be called synchronised swimming, with music and held poses), and the long race in open water. Those are the five.

At the Olympic Games, aquatics means the water sports在奧運裡，aquatics指的是水上運動： swimming in a pool游泳池裡的游泳， diving from a board從跳台跳水， water polo (the ball game in the pool)水球（泳池裡的球類比賽）， artistic swimming (the one that used to be called synchronised swimming, with music and held poses)花式游泳（以前叫synchronised swimming，配著音樂做出定格動作的那項）， and the long race in open water以及公開水域的長距離游泳。 Those are the five就是這五項。

Though actually, outside the Games people use aquatics more loosely for water sports in general, or for the building where you do them — an aquatics centre is a big public pool, often with diving boards and a warm teaching pool as well. The word feels a little official; a child going to the pool would just say swimming.

You almost always meet it as aquatics, not an aquatic. Teachers and sports news like it because one word covers the whole water family of events.
