A device has a lightweight inner bladder and an outer layer that covers the inner bladder. The inner bladder bunches up, crunches, becomes pleated, folded or the like against the inner surface of the outer layer. The bunched up surface of the inner bladder may be flattened and/or reconfigured upon impact, thereby absorbing energy. The bunched up inner bladder may create an uneven surface on the outer layer thereby altering the manner through which the device travels through the air. The device may be configured for any of a variety of sports or games such as, for example, a simulated soccer ball, football, rugby ball, baseball and/or softball, a tennis ball, a beachball or other oversized ball, a golf ball, a flying disc, a weighted punching bag, or any of a wide variety of devices for play and/or training.

A recreational ball formed from a plurality of layers, a bladder and a valve. The plurality of layers is formed from a variety of different materials. Each of the materials that each of the plurality of layers is formed from is specifically oriented to create a ball that is durable, comfortable, and militates against air leaking from the bladder of the ball, as well as moisture seeping into the plurality of layers. The valve extends from a first layer of the plurality of layers, through the plurality of layers and is insertingly positioned within the bladder.

Described is a sports training system that can be used to assist pitchers in identifying foot placement and mechanics during a pitching motion. The sports training system includes a mat and plurality of foot pads. The mat is designed to have at least a pitching plate and a plurality of grid zones, while the foot pads are used for placement in one or more of the plurality of grid zones to assist the pitcher with foot placement.

A method and system of officiating a sporting event with a player on a field of play with a play boundary is disclosed. A ball sensor in a ball of sport and a player sensor in player equipment may be detected when breaking a detection field generated by a field generator along a play boundary. Play data and participant data may be sent to a processor to determine an officiating result, and the officiating result may be sent to an official's mobile device for confirmation.

An apparatus, methods and systems are provided for creating a shot information database comprising ball flight data combined with a user's intended golf shot type, the user's golf club selection, the user's setup position and dynamic swing adjustment made to produce the golfer's intended golf shot with the selected golf club to produce said golf shot. This invention presents to the user such information as a score, wherein said score reflects the accuracy of the user's golf shot. In addition, the ball flight data includes a trajectory angle, an elevation angle, a quadrant in a target plane comprising an x-y coordinate system coplanar with said target plane and a characterization of a type of golf shot produced by said golfer, such as a draw. Another embodiment of this invention performs a statistical analysis on said shot information to create basic and advance shot reports to assist a golfer or a third party to learn a golfer's strengths and weaknesses with respect to the user's ability to hit certain golf shots with certain golf clubs; in addition, the golfer is able to learn with setup keys and swing keys are more successful in hitting certain golf shots with certain golf clubs. In this manner a golfer or user is able to learn what it takes to improve his/her golf swing while better understanding their particular capabilities and tendencies. Another embodiment of this invention allows a golfer to practice indoors in a manner that simulates outdoor practice at a driving range, For golfer's who are visually impaired, this invention provides accurate feedback to a golfer who is visually impaired to the extent that they cannot see the flight of the struck golf ball. Said golfer benefits little at a driving range where they are unable to see the results of their golf swings This apparatus characterizes each golf shot using a particular practice ball which interoperates with the apparatus in such a way to enable said apparatus to acquire said ball flight data. Another embodiment of this invention allows a golfer to enter or speak remarks on the results of the previous shots or, more simply called post shot remarks. All shot information is stored in permanent storage for later historical performance analysis.

A training device that includes a sports implement connected to an air resistance member in near engagement by a connection system. In one arrangement, the air resistance member has a first and a second layer of material. The training device reduces the distance the sports implement travels by application of air resistance once airborne once thrown, kicked, struck, or otherwise moved by an athlete. While still under the influence of the athlete, the training device's resistance to air strengthens the athlete during the course of athletic movements.

A lacrosse training ball that is made up of a shell that defines an enclosure having an interior volume is disclosed. The shell includes a plurality of pads connected along a plurality of seams sewn with a thread having a finishing knot. The interior volume is substantially occupied by a filler that includes a mixture of a first material and a second material.

A golf swing training device is disclosed that will provide instant feedback on the position of the golfer's clubface at impact. The device consists of a rebounding surface enclosed, and attach to a frame with a safety net, a goal, a golf mat to provide a hitting surface, and a ribbon attached from the bottom of the frame to the golf mat for alignment and shot analysis. The rebounding surface faces opposite the goal such that when a practice golf ball hits it, it will land in the goal if struck properly. Its angle may be adjustable to accommodate different clubs for a proper rebound into the goal. The rebounder surface may be made from a foam material with a fabric covering that when struck, leaves an indention for visual target reference, repels the ball, and indicates ball spin by referencing where the ball landed inside or outside the goal.

The invention relates to a play device intended for juggling, comprising upper branches, and lower branches, an upper linking part, and a lower linking part, the upper and lower linking parts being aligned along a main axis, and a peripheral armature, of annular shape arranged between the upper linking part and the lower linking part along the main axis, said upper branches and lower branches forming an external envelope delimiting an interior space of the play device and being configured to deform in such a way that the device passes from an initial shape to a bowed shape when a user bounces the play device on his body, and from the bowed shape to the initial shape after the bounce.

The invention relates to a method of motion analysis for an assembly comprising at least one juggling device, the at least one juggling device 1 comprising a motion analysis module, intended to acquire at least inertial data, the method comprising the following steps: a step A of acquiring data, called acquired inertial data, relating to the movements of the at least one juggling device, a step B of detecting a bounce, called juggle, of the juggling device on the body of a user on the basis of the acquired inertial data, a step C of counting the number of successive juggles of the juggling device.

The invention further relates to a computer program enabling the implementation of such a method and an information storage means comprising instructions for the implementation of such a method.
