Swimming can't really be played. Swimming is more of a social event. You can swim for sport but its simply a timed race of a set stroke over a certain distance. E.g 50m Butterfly. Swimming is used, however, in sports such as water polo.
Vigorous activity refers to aerobic activity. This is exercises such as running, swimming, playing ball sports, or other activities that make the heart rate race. Vigorous activity is healthy, however it is unhealthy when done in excess without rest or recovery.
