Final answer:
Recreational sports like tennis or basketball are classified as aerobic exercises, which are activities that strengthen the cardiovascular system, typically engaging continuous, moderate-intensity activity.
Step-by-step explanation:
The classification of exercise that includes recreational sports such as tennis or basketball is aerobic exercise. These activities are known to strengthen the cardiovascular system and are performed at a moderate level of intensity over a longer duration.
