A sports ball position reckoning system, comprising instrumentation in a sports ball that allows one or more players to be electronically located on a playing field or court each time a goal attempt is made. The instrumentation is configured to fit through the opening of an inflation port of the ball when the fill valve is removed. The system works in conjunction with a performance monitor system that detects ball interactions with a goal and is used to trigger the system to analyze the ball flight path just prior to the goal interaction. Player position is ascertained through the localization of the initial position of the ball's flight path. For multiple players, each player is pre-assigned a uniquely marked ball. The identity of the player who executed the attempt is determined through the player's association with the ball that executed the flight path towards the goal.

A basketball practice device for training a player to shoot with hir or her arms up includes a base member. The basketball practice device also includes a vertical member coupled to the base member. The vertical member has a lower end coupled to the base and an upper end. The basketball practice device further includes a horizontal member coupled to the upper end of the vertical member. Vertical guideposts may be coupled to the horizontal member.

A visual aid mounts to a basketball rim for shooting practice to help focus the shooter’s eyes near the back of the rim, behind the center of the rim. The visual aid is shock absorbing so as to dissipate forces of impact when the ball hits the device, so as to maintain the device in position inside the net. The device includes straps which are slidably mounted through slots in the body so as to be resilient or elastic during ball impact. Notches in the straps prevent the straps from inadvertently pulling out of the slots upon ball impact.

A training system having a support structure, where the support structure includes two or more supports forming a tunnel shape, resulting in two or more openings in the structure. The supports of the support structure also having one or more adjustment mechanisms and skin pieces. The supports, the ground, and a boundary wall defining an inner training area. The inner training area being adjustable in volume.

An apparatus includes a non-transitory computer-readable medium to direct a processor to: receive signals indicating a made basketball shot or a missed basketball shot of a basketball by a person during a basketball shooting session, receive signals indicating a location from which each made basketball shot is made, and determine and output a user cumulative score for the person for the basketball shooting session, the cumulative score being based upon the location of each made basketball shot.

A sound absorbing rebounding device provides a way for a person to practice dribbling a basketball while minimizing sounds and vibrations emanating from the basketball and the device during such practice. The device has a frame, a rebounding surface that mimics or replaces the hard surface on which a user would normally dribble to cause a rebounding effect, and a base to separate or space the rebounding surface from the floor, so that sounds and vibrations during bouncing of the basketball are not transferred to the surface on which the device is resting. The frame shape allows the user to practice dribbling in all different directions around the user's body placed relative to the user's legs, such as a T, an H, or the number 8. The device may be collapsible via hinges placed within its frame that allow the device to be collapsed in varying degrees of compactness.

A basketball training device for mounting on a basketball hoop. The basketball training device includes a blocking body that is dimensioned so as to block shot attempts that are at an undesirable shooting angle or will result in an undesirable bank angle. The basketball training device may be a part of a kit which includes a placement apparatus that can be used to grab and place the basketball training device onto the rim of a basketball hoop.

A ball supply apparatus includes: a housing coupled to the upper portion of the column structure, wherein a top portion of housing is partially opened, wherein the housing is divided by a partition into a ball storage portion and a ball discharge portion, wherein a bottom face of the ball storage portion is inclined downward toward the ball discharge portion, wherein a first opening is formed in a bottom of the ball discharge portion, and a second opening is formed in the partition at a lower portion thereof; a rotatable opening/closing plate rotatably coupled to the partition, wherein the rotatable opening/closing plate is configured to rotate to open/close the second opening; and a ball discharge tube rotatably coupled to the ball discharge portion at the first opening, wherein the ball discharge tube ball-communicates with the ball discharge portion via the first opening.

An athletic coaching method and jersey system are provided. The method utilizes jerseys with securing elements attached thereto. Number panels having specific player numbers are secured to the jerseys for use during practice. Scout team players wear the jerseys during practice. Each scout team player has a different number to represent the jersey number of a player on an opposing team in an upcoming game. The method allows coaches to more realistically simulate a game against an opposing team in practice. When the opposing team changes for the next game, each scout team player can continue to wear the same jersey but change the jersey number by switching number panels to represent a different player on the team of the next opponent. Thus, jersey numbers can be changed so that a game can be simulated for any opponent.

A modular resistance force system includes an axle configured to be rotatable around a rotational axis and one or more resistance mechanisms. Each of the one or more resistance mechanisms includes a resistance element disposed about a portion of the axle, a resistance element housing configured to house the resistance element and a resistance substance disposed between the resistance element and the resistance element housing. Either the resistance element or the resistance element housing is selectively engaged to rotate with the axle. A resistance between the resistance element and the resistance substance causes a force to be applied to the axle when the resistance element and the resistance element housing move relative to each other.
