A method and apparatus for detecting a jump of a moving sportsman and separating the jump from other sportsman motion is described. Accelerometer data generated by a sportsman's motion is received in a computing device. The computing device is used to apply fuzzy logic membership functions to a plurality of parameters associated with the accelerometer data to detect a pattern associated with jumps. A subset of the data is identified as representing a jump based upon the detection of the pattern. The determination is used in the computing device to transform data, whereby jumps are separated from other sportsman motion.
