A volleyball training apparatus has a laterally extending arm supported on a riser. A resilient member such as a spring is operably connected within the arm. The resilient member is connected to a flexible connector, such as a cable, that is connected to a volleyball. A series of spacers retains the volleyball away from the rigid arm. The height of the arm may be adjustable to locate the volleyball at a desired height. After a user strikes the volleyball, the volleyball is displaced from its original static position, but quickly is snapped back into the static position by the resilient member pulling the volleyball toward the arm against the spacers.

A device configured to encourage a tennis player to hit a tennis ball higher over a tennis net includes a pair of telescoping rods. Each pair of telescoping rods can include an inner segment and an outer segment. The outer segment can surround at least a portion of the inner segment. The outer segment can be movable with respect to the lower rod to at least one raised position and at least one lowered position. The lower rod of each telescoping rod can be attached to a vertical support post at opposing ends of a tennis net or directly to the tennis net. At least one fastener can be attached to the outer segment of each pair of telescoping rods. A string can attach the at least one fastener of each telescoping rod. The string can extend above and generally parallel to a top surface of the tennis net.

In an embodiment, a volleyball training device includes a handle with two sliding grips. The sliding grips may each slide between one end of the handle and the center of the handle. The handle may include an anchor connected through its center. One or more foot straps, each including an anchor, may be connected to the handle anchor with a resistance band or strap. Two foot straps may be connected to the handle anchor with separate resistance bands, or by s single resistance band threaded through the handle anchor.

An apparatus comprising a pair of gloves, wherein an index finger portion of a left glove is connected to an index finger portion of a right glove, and wherein a thumb portion of the left glove is connected to a thumb portion of the right glove.

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.

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.

A sports training apparatus for training athletes to deliver a ball or other object at an appropriate arc. The sports training apparatus includes an adjustable horizontal target that is positioned between the athlete and the target. It gives guidance to the athlete at the time of release. The athlete's height, game being played, desired arc, technique employed and position on the court determine the appropriate configuration, placement, and use of the sports training apparatus described herein. Athletes use the sports training apparatus repeatedly to train, learn, and be able to repeat the desired arc for a particular shot in their sport.

The scorekeeping system includes a plurality of scoring elements. An upper bracket can be secured a first string having a first portion of the plurality scoring elements and a second string having a second portion of the plurality of scoring elements. The first string can have a first thread and a second thread, each of the first thread and the second thread being threaded through the first portion of the plurality of the scoring elements. The second string can have a third thread and a fourth thread, each of the third thread and fourth thread being threaded through the second portion of the plurality of the scoring elements.

A training system, kit, and method including a weighted wearable equipment, e.g. gloves, having a sensor (e.g. accelerometers, gyroscopes, photoelectric sensors, position sensors, tilt sensors, pressure sensors, temperature sensors, blood pressure sensors, heart rate monitors, and SpO2 sensors) and including a weight enhancement (e.g. weight bodies in closed pockets); a non-weighted wearable equipment of the same type as the weighted wearable equipment, the non-weighted wearable equipment having a sensor and. not including a weight enhancement; and a training application in functional communication with each of the weighted wearable equipment and the non-weighted wearable equipment and having a data processor that includes instructions for: analyzing data received from the sensor of each of the weighted wearable equipment and the non-weighted wearable equipment and generating predictive information derived from exercise training data from the sensors.
