An inflatable sport ball (10), such as a basketball, a football, a soccer ball, a volley ball or a playground ball, is provided with a self-contained inflation mechanism for inflating or more likely adding pressure to the ball. The mechanism is a self-contained, manually operable pumping chamber which is inside of the ball and which is operable from outside of the ball to compress the chamber and pump ambient air into the ball.
