RAPID CHANGE OF DIRECTION (COD) MOVEMENTS ARE COMMONLY PERFORMED IN MANY TEAM SPORTS SUCH AS SOCCER, ICE HOCKEY, BASKETBALL, AND NETBALL. COD MOVEMENTS MAY OCCUR IN RESPONSE TO AN OBJECT (E.G. BALL, PUCK, BOUNDARY LINE, ETC), IN RESPONSE TO PLAYER MOVEMENTS (E.G. TEAMMATES), OR IN AN ATTEMPT TO EVADE AN OPPONENT. THERE ARE A WIDE VARIETY OF STRATEGIES USED TO COMPLETE COD MOVEMENTS; HOWEVER, LITTLE RESEARCH HAS INVESTIGATED THE STRATEGIES OR TECHNICAL CUES THAT RESULT IN SUPERIOR PERFORMANCE. THIS ARTICLE PROVIDES A DESCRIPTION OF 3 MOVEMENT STRATEGIES (FALSE-START PIVOT, FORWARD-MOVING SIDESTEP, AND PIVOTING CROSSOVER).
