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.

An apparatus for teaching baseball pitching includes a substantially flat panel having a substantially rectangular shape with adjustable height and width dimensions. The apparatus further includes at least two support members for supporting the flat panel in an upright position. The length of the support members can be adjusted to obtain a desired distance between a bottom edge of the flat panel and the ground.

According to one exemplary embodiment, an apparatus, system, method and/or computer program product may provide an athletic training performance analysis apparatus including at least one athletic training performance analysis device including at least one electronic sensor coupled to the at least one athletic training performance analysis device; at least one user interface coupled to the at least one athletic training performance analysis device configured to interact with a user to receive a user selection of at least one training performance analysis routine, the at least one user interface may include: at least one electronic computer processor coupled to the at least one electronic sensor; at least one input device coupled to the at least one electronic computer processor to receive the user selection; at least one output device coupled to the at least one electronic computer processor to provide output to the user; at least one electronic memory coupled to the at least one electronic computer processor; and at least one of: wherein the at least one electronic computer processor is configured to save or retrieve the at least one training performance analysis routine from the at least one memory; where the at least one electronic computer processor is configured to electronically monitor and electronically analyze the at least one training performance analysis routine based on the at least one electronic sensor; wherein the at least one electronic computer processor is configured to randomize at least one challenge by the at least one athletic training performance analysis device; or wherein the electronic computer processor is configured to at least one of: combine a plurality of previously saved of the at least one training performance analysis routine, or shuffle a plurality of previously saved of the at least one training performance analysis routine.

A system for communicating pitch selections wirelessly from a wireless transmitter has a coded signal generator that generates coded signals in accordance with selected pitch types. A receiver decodes the received coded signals, selects an audio file based on the received coded signal and generates an audio signal announcing the selected pitch type based on the transmitted selected pitch type in accordance with the received coded signal. The audio signal is transduced by a bone conductor transducer so that the player can hear the announced selected pitch type through bone conduction.

A pitching training tool includes: a hollow ball; a shaft; and a wing. The shaft has one end attached to the ball, and another end attached to the wing. The ball and the wing are spaced apart from each other by a length equal to or greater than a sum of a diameter of the ball and a length of the wing with the shaft interposed between the ball and the wing.

A non-spherical training ball for training a pitcher to throw a ball with proper technique is provided. The training ball has a hollow body having a spherical surface forming a spherical cap having a height greater than the radius of the sphere from which the spherical cap is formed and a substantially planar surface forming the spherical cap plane. Sidewalls form the hollow cavity of the hollow body, the sidewalls have a spherical surface sidewall portion forming the spherical surface of the hollow body and a planar surface sidewall portion forming the substantially planar surface of the hollow body. The sidewall thickness of the planar surface sidewall portion has a thickness greater than the sidewall thickness of the spherical surface sidewall portion.

A device for training a person to throw a ball includes a body. The body defines a first planar surface, a second planar surface, and a curved surface. The first planar surface is defined at a first end of the body. The second planar surface is defined at a second end of the body. The curved surface is defined between the first planar surface and second planar surface. The device has a center of mass that is located outside of the geometric center of the device.

A pitch training ball includes a center portion, a first cap, and a second cap. The center portion is opaque and has a first planar surface at a first end thereof, and a second planar surface at a second end thereof opposite to the first end. The first cap portion has a first base that is adjacent to the first planar surface. The second cap portion has a second that is adjacent to the second planar surface. The first cap, the center portion, and the second cap cooperate to define a baseball shape. The first and second caps are transparent to translucent.

A protective field screen system that includes a screen frame system (including a screen frame and a protective screen that includes a netting coupled to the screen frame), a base frame to be disposed on a supporting surface, and resilient members. The screen frame coupled to the base frame by way of the resilient members, and the resilient members to deform to facilitate movement of the screen frame relative to the base frame.
