Tennis racket with enhanced gaming features

摘要

A tennis racket comprising: a handle with a heel; a head configured to support string; and a groove that connects the handle and the head; where the racket has a power greater maneuverability to about 4500, the ratio Maneuverability Power to being governed by the equation: Formula ** ** where SW = the moment of inertia in kilograms per square centimeter of tennis racket around an axis of swing weight that is perpendicular to a longitudinal axis of the tennis racket parallel to a striking surface of the tennis ball contained by the head, and passing through a point of the handle is 101.6 mm (four inches) from the heel along the longitudinal axis, ** ** Formula where wt = the weight in grams of the racket, b = the distance in millimeters between a center of gravity of the racket and the heel, TW = the moment of inertia of the racket about the longitudinal axis, and PUW = (Wt) (b)
