A method for monitoring the motion of a sport ball that has been impacted by an individual during the course of an athletic activity includes the steps of the sport ball sampling motion data from one or more of its motion sensors at a sampling rate, the sport ball saving the sampled motion data in a buffer at a first saving rate, the sport ball saving at least a portion of the sampled motion data in a file separate from the buffer at a second saving rate, wherein the second saving rate is adjustable separate from the sampling rate and varies during the course of the athletic activity based on impacts to the sport ball, and the sport ball wirelessly transmitting the sampled motion data in the file to a portable electronic device.
