Basketball is one of the indispensable equipment in NBA games. It has some unique characteristics and requirements to ensure the fairness of the game and high-level competitive experience.
Characteristics of basketball
Basketball used in NBA games has the following characteristics:
1. Size standardization: The standard size of basketball used in NBA games is 29.5 inches (about 75 cm) of ball circumference, weighing about 22 ounces (about 620 grams). This size is suitable for most players to hold and control the ball, while maintaining the stability and controllability of the ball.
2. Durable material: basketball used in NBA games is usually made of leather or synthetic materials to ensure durability and long-term use quality. The leather basketball has better feel and touch feedback, while the synthetic basketball is more durable and not susceptible to moisture and sweat.
3. Air pressure standardization: basketball used in NBA games must be inflated according to the specified air pressure, usually 7.5 to 8.5 pounds per square inch (about 0.5 to 0.6 atmospheric pressure). This standard air pressure is designed to ensure the flexibility and controllability of basketball, so that players can better control the trajectory and bounce of the ball.
Requirements of basketball
NBA has very strict requirements on basketball to ensure the fairness and consistency of the game.
1. Brand certification: NBA only allows the use of officially certified basketball brands, such as Spalding. These brands must comply with NBA regulations and pass strict quality inspection and testing.
2. Ball state: the basketball must be kept dry, clean and free of obvious wear. Any basketball with obvious defects or damages will be replaced or repaired.
3. Use in competition: basketball can only be used in competition, not in other occasions or training. This can ensure the state and quality of basketball during the game.
In general, the basketball used in NBA games has standardized size, durable material and regulated air pressure. These requirements and characteristics ensure the fairness of the competition and high-level competitive experience. Both players and spectators can feel the charm and passion of NBA games through this special basketball.
