Basketball players need all of these physical attributes because they all contribute to a basketball player's ability to succeed on the court. Cardiovascular endurance and muscular endurance are essential because basketball games are long and require a high degree of endurance to maintain the players performance throughout the game.

Body composition, balance, and agility are all also essential physical attributes of a successful basketball player.
