Abstract

The present disclosure relates to an athletic performance monitoring device that could be worn over a limb of an athlete for assessing the motions of the limb. The device comprises of a flexible sleeve that could be worn around the limb; an elongated flexible member that can be mounted over the flexible sleeve and multiple motion sensors embedded at appropriate positions over the elongated flexible member for sensing the motions of the limb. The device is particularly useful in the sport of cricket wherein the device could be mounted over the bowling arm of the bowler for differentiating between the illegal and legal bowling action by assessing the kinematics of the elbow joint during the latter stages of ball delivery. Further the device may be configured for monitoring the arm force, action time, and twist in the bowler'"'"'s arm just before the ball is released in the course of ball delivery.
