CISI Inc. is a scientific research unit, which publishes books, produces videos and other "hockey knowledge" educational materials for players, parents, coaches, skating rinks and hockey organizations worldwide. Intensive research into the biomechanics, physiology and psychology of athletic performance generated a system of on-ice and dry land exercises that develop the quickness, maneuverability and the reaction time necessary to excel in the high-speed, unpredictable conditions of the hockey game.
