David Pearsall and Rene Turcotte, along with graduate student Yannick Michaud-Paquette of McGill University wanted to find out how the mechanics of the hockey stick and blade affected the flight of the puck and be able to point to specific movement patterns which resulted in more accurate shots. As Turcotte told LiveScience, “Very little information exists describing the kinetics and kinematics of skating and shooting skills. We are for the first time learning about how skills are executed in an optimized fashion.”
Twenty five hockey players, ranging in skill from novice to varsity level players, were told to shoot pucks at targets located in the four corners of a goal until they had hit each target ten times. They were allowed 20 shots per target with their accuracy percentage recorded. Their stick and the pucks were marked with reflective stickers that could be seen by six 3-D motion capture cameras placed around the goal. Everything from the angle, pitch and yaw of the stick blade to the stick velocity and contact time between puck and stick were measured as possible variables for accuracy.
