Abstract: A system for assessing athletic performance comprises a mounting device wearable by an athlete, a sensing device attachable to the mounting device, and a base unit. The sensing device comprises acceleration sensors for measuring acceleration data during an athletic test to produce at least three acceleration signals, rotation sensors for measuring rotation data during the athletic test to produce at least three rotation signals, signal conditioning hardware for conditioning the acceleration and rotation signals and sampling the acceleration and rotation signals at a sampling rate to produce acceleration and rotation data, and, a wireless communication device for transmitting the data. The base unit comprises a wireless communication device for receiving the data, a feature extractor for extracting features relating to athletic performance from the data based on a plurality of expected events of the athletic test, and, an output device for outputting the extracted features.
