ABSTRACT:
An improved striking implement is provided. The striking implement includes an essentially cylindrical metal shaft having a central cavity. A massive load is disposed within the central cavity at some distance from the upper end of the implement. When the striking implement is swung to contact an object to be struck, the load imparts a secondary impact, additive to the primary impact of the shaft upon the struck object, thereby increasing the forcefulness of the blow as a whole. Appropriate choice of suspension means for the load and situating of the load and suspension means optimize the additional energy imparted to the struck object. In the case in which the implement is a sports bat for striking a ball such as a softball or baseball, significant increase in the speed with which a hit ball leaves the bat, and thus meaningful athletic performance enhancement, is attainable by using the cavity-loaded bat illustrated as an embodiment of the invention.
