A swing training device for improving the proper swing of ball sports including but not limited to baseball and softball. The swing training device has an elongated barrel having a substantially quasi-stadium cross-sectional shape connected to a handle portion. The hitting surface of the barrel is one of the two opposing curved surfaces of the circular segments of the quasi-stadium cross-sectional shape. The swing training device may be a modified regulation wood bat that is modified via diametrically opposing longitudinal tangential section cuts so that the un-cut curved hitting surface is oriented such that the grain runs against the ball at contact.

A kinetic motion learning device includes an information storage unit configured to associate and store in advance a pitching motion video and pitching trajectory information for a plurality of pitches actually delivered by a pitcher on a potential opponent team, and is configured to read a set of the pitching motion video and the pitching trajectory information stored in the information storage unit, output the pitching motion video being read to a projector, output the pitching trajectory information being read to a pitching machine, and control motion timings of the projector and the pitching machine so that a time of ball release of the pitcher in the pitching motion video displayed on a screen and a time of the pitching machine launching the ball with the pitching trajectory information match. The projector is configured to project the pitching motion video onto the screen so that the pitching motion video is displayed on the screen at a motion timing controlled by the kinetic motion learning device. The screen includes a hole through which a ball launched by the pitching machine can pass at a position of ball release of the pitcher in the pitching motion video displayed.

A training apparatus for baseball training includes a base and training attachments that may be attached to the base to allow a user to practice a variety of training techniques. The base may be modular so that it has an adjustable width and disassembles into separate components. At least one training attachment is designed to train a batter to properly incorporate thrust into a swinging motion when swinging a baseball bat. The attachment has a pivotally mounted member with a contact element attached to the top end of the member. The member pivots forward and downward when the user's knee contacts the contact element when properly executing a swinging motion. Thus, the training attachment provides direct and immediate feedback to the user regarding the user's batting form. Other training attachments may be used for hitting balls and for pitching to targets strategically placed around a strike zone.

A system and a method related for evaluation of sport ball data. The method includes calibrating a first coordinate system of a first camera to a second coordinate system of a baseball field; capturing, with the first camera, one or more images including a first batter; determining biometric characteristics of the first batter based on the one or more images and the calibration of the first camera to the baseball field; mapping the biometric characteristics of the first batter to an upper positional limit and a lower positional limit of a first strike zone for the first batter; and determining positional limits of the first strike zone in the second coordinate system.

An example ball glove ball catch system includes a ball glove and a ball catch. The ball glove may comprise webbing and a hand opening. The ball catch may be located between the hand opening and the webbing.

A visor that can be removably attached to a variety of field masks, including those used in softball and baseball and other sports, to protect the user from weather elements and minimize sun damage while not affecting play and withstanding movement. In some embodiments, the visor may include a curvilinear base having at least one recess. The visor may additionally include a brim attached to, or formed with, the base. The visor may further include a fastener received in the at least one recess, where the fastener is configured to secure the visor to the field mask.

A sports bat article, and a method of forming the sport bat, is disclosed. The method may include shaping an elongate wood piece to have a barrel portion and a handle portion suitable to be used as a sport bat, with the wood piece having a shaped surface. The method may also include applying a substance to the shaped surface of the wood piece in which the substance may be effective to harden a surface of the wood piece. Applying the substance to the shaped surface of the wood piece may include immersing a portion of the wood piece into a pool of the substance.

A ball assembly for a swing trainer that withstands repeated hits with forces applied by professional athletes. The ball assembly comprises a ball, a wire rope, a ball stud swaged to one end of the wire rope and a connector sleeve swaged to the other end of the wire rope. A whole is drilled through the exact center of the ball and wire threaded therethrough. After the ball stud and connector sleeves are swaged to the ends of the wire rope, the ball stud is pressed into the hole in the ball. The wire rope may be coated to extend life.

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 shoe has a sensor system operably connected to a communication port. Performance data is collected by the system and can be transferred for further use via the communication port. The shoe may contain an electronic module configured to gather data from the sensors. The module may also transmit the data to an external device for further processing. Users can use the collected data for a variety of different uses or applications.
