Using a dynamic moment of inertia to increase bat speed in baseball players using the “Pro-Impusle swing trainer”

The common method of training and warming-up in baseball is by using weighted disks that are added to the player’s baseball bats. The current scientific evidences showed that the use of these devices doesn’t improve the performances of the players and actually slows down their swing speed and batted ball speed. Our partner developed a new device that focuses on increasing the swing speed in rotational sports such as baseball. The prototype uses elastics to allow a variable resistance and some timing aspect to the player’s training.
