A training, rehabilitation, and recovery system comprises an exercise apparatus including a user interface member coupled to a plurality of links and joints, brakes capable of resisting movement of at least a subset of the links or joints, and sensors capable of sensing movement at the joints or the user interface member. The system also includes a processor configured to receive from the sensors positional data of the links or joints over an initial movement of the apparatus by a user, from which positional coordinates of the user interface member are calculated and a reference trajectory is established. An end space is defined based on the reference trajectory. Over a subsequent movement of the apparatus by the user, the processor receives additional positional data and determines a completion of a repetition based on the positional coordinates of the subsequent movement and the defined end space.

A plastic ball having a generally spherical shape with a plurality of depressions located in only one hemisphere of the ball and lying along circumferences of the ball that pass through the center of the hemisphere, in which the depressions are equally spaced radially about the center of the hemisphere.

A modified sphere structure including: a sphere body with a groove formed on a surface of the sphere body along a distribution path; a light source module disposed in a containing space of the sphere body, wherein the groove is connected to the containing space to define a light releasing space and light emitted from the light source passes through the light releasing space; and a light guiding member filling to the light releasing space to allow the light emitted from the light source to be distributed on the light guiding member along the distribution path and transmitted to outside of the sphere body.

A training aid comprises a plurality of elongate bodies. Each of the elongate bodies comprises a first end and a second end. A holder is coupled to the first end, and includes a clip extending along each of the elongate bodies and forming an accommodating space. The accommodating space is oriented to accommodate an object to be inserted along each of the elongate bodies in a direction pointing the first end to the second end. Each of the elongate bodies is bendable to a deformed state and is fixable in the deformed state.

A sports training system including a set of numbered panels to be placed on a playing or training surface. The training system uses circular panels strategically positioned on the ground to guide a player's feet into a proper sport stance for multiple sports, including baseball, soccer, and basketball. The training system provides multiple circle-shaped panels. The panels are sized appropriately such that when a player being trained places feet on opposite sides of the panel, the player is placed in an athletic stance, approximately shoulder-width apart. The location of the panel on the playing surface places the player in a proper position. The panels may be formed from neoprene. The panel lays flat on a playing surface. Each panel has indicia printed on one side. The panels are positioned throughout the playing surface and may be located appropriately for certain types of offensive or defensive formations.

A sports training device is configured to be supported by one of the below-grade base anchors typically available at baseball and softball fields. The device comprises a frame made up of a net holding portion and a support portion configured to support the net holding portion. The support portion includes an insert post configured to fit into the base anchor. The net holding portion is configured to be rotatable relative to the support portion about a vertical axis. The net holding portion can also be configured to be movedand secured in a positiontransverse to the vertical axis. The training device can thus be placed in several configurations in order to provide a net target in a desired position so that a player can practice delivering a ball to the net.
