Provided is a swing speed analyzer for mounting on a swinging implement and comprising a first accelerometer, a processor and a shock attenuator. The processor uses an output from the first accelerometer to compute a swing speed of the swinging implement. The shock attenuator is comprised of a material that is sized and dimensioned to dampen an impact shock wave by more than 50% at 125 Hz. The material is preferably sized and dimensioned to dampen the impact shock wave from more than 1000 g to less than 500 g. Suitable attenuators can include viscoelastomeric materials such as foam. The swing speed analyzer can advantageously include any of a releasable attachment mechanism, a liquid crystal or other visual display, a second accelerometer, and a strain gauge. The analyzer can advantageously be attached to a golf club, a tennis racket, a baseball bat, or a hockey stick.

The present application relates to devices and methods for adjusting the weight of a racket using variably weighted racket damping devices.

A tennis racquet that provides audio or visual feedback to a player. Sensors sense the impact of a ball on the racquet. A feedback indictor provides visual or audio feedback.

The present invention relates to a system and a method for gathering ball game data and in particular tennis match data in real time. To this end the system comprises a hands-free voice receiving means (4) adapted to receive words spoken by the player (2) wearing the receiving means. The words are then analyzed by an analyzing means adapted to analyze a dedicated ball game vocabulary used by the player. The analysis of the spoken words translates these words into digital match data. This data can be displayed, at least as score of the game by a display (10). More elaborate match data information can be gathered. Such data may be fed to an expert system giving back advice to the player.

A lacrosse stick holder mounts on a vertical surface and serves as complete storage system for the stick, horizontally or vertically, and other equipment. The holder has a base or mounting plate, and one or more forked projections. The forked projections define a notch or slot that receives the shaft of the lacrosse stick, and may be formed of spring-loaded jaws that spread to allow the shaft to pass and close over the shaft to secure it removably in place. A hook or hooks are provided on the base plate for attaching a sports bag, gloves, pads or other ancillary equipment. Spacers permit a series of these holders to be attached in a row for storing multiple sticks.

A tennis training aid can be used to teach proper wrist and racket position for swings such as a forehand ground stroke, two-handed backhand stroke, or volley. A training aid includes a forearm attachment member that can be quickly and easily attached to a player's forearm. A wrist positioning member can be attached between the forearm attachment member and the player's racket to maintain proper wrist angle and racket position. A first wrist positioning member can be used for a forehand ground stroke or two-handed backhand stroke, while a second wrist positioning member can be used for volleys. The forearm attachment member can include a rotatable member, and the wrist positioning member can be slightly elastic, in order to allow the racket to move slightly with respect to the wrist, and to allow for slight wrist movement, in order to provide a natural feel for the player.

A training device to improve tennis skills. The device includes wristbands for encircling each wrist of a user and a tension device with an umbilical attached to it and to the wristbands.

A tennis training apparatus and method of use thereof, for improving a forehand and/or backhand of a tennis player. The apparatus includes a wristband, an “L”-shaped bracket attached to the racket, and an inflexible strap linking the L-shaped bracket to the wristband. When the strap is tightened, it causes the wrist to bend backwards in extension at an approximately ninety degree angle to the forearm. A second component of the training aid is a restraining plate in the form of a torso attachment worn by the player, wherein the torso attachment retains alignment of the player's hand, hips and shoulders; thereby, forcing the player to rotate his hips to perform a stroke. The torso attachment may be subsequently employed or removed during two-handed backhand strokes. The tennis training apparatus significantly improves the power and control of strokes, and also reduces and/or prevents the risk of developing tennis elbow.
