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 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 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.

A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

A bat includes a handle having a proximate end and a distal end, a barrel having a hollow portion that accommodates the distal end, and a first damping section at least partially sandwiched between the handle and the barrel in the interior of the hollow portion. The material of the first damping section has a D hardness of 60 or more, a loss coefficient tan δ of 0.11 or more as determined under conditions of a temperature of 20° C., a frequency of 150 Hz, and the amount of strain 3000 μST, and a loss coefficient tan δ of 0.09 or more as determined under conditions of a temperature of 20° C., a frequency of 500 Hz, and the amount of strain 3000 μST.

A sensing system and method determines whether a slow pitch softball has been delivered in a strike zone. The system includes: a dual, mirror image slow-pitch software home plate; the home plate having an upper surface and a lower surface; the lower surface configured for attachment to ground; the upper surface comprising a pressure or impact sensing array covering at least edges of the upper surface of the home plate; the sensing array having a battery source for powering the system; the sensing array issuing an electrical signal when sensing pressure or impact; and the electrical signal connected to an audio or visual output device that indicates receiving of the electrical signal by a visual or audio emission.

Representative embodiments of the present technology include a bat having a barrel shell and a frame structure. The barrel shell may include a barrel region of the bat and part of a tapered region of the bat. The frame structure may include a first portion positioned outside the barrel shell and a second portion positioned inside the barrel shell. In some embodiments, a distal end of the frame structure is in the barrel region but is longitudinally spaced from a distal end of the barrel shell. In some embodiments, the distal end of the frame structure is longitudinally spaced from an end cap of the bat. The barrel shell may flex or pivot relative to the second portion of the frame structure. In some embodiments, the only connection between the frame structure and the barrel shell within the barrel shell may be within the tapered region.
