A recreational game is disclosed, including at least one flying disc, wherein a player on each of a set of teams throws the flying disc towards two sets of goal rings positioned on opposing sides of one another. The player on each set of teams attempts to throw the flying disc through one of the two sets of rings to obtain a point value. At least one ball is utilized as a defensive element to prevent the flying disc from travelling through one of the rings.

A body weight support system includes a support track, a trolley, and a power rail. The support track has a first portion and a second portion. The trolley has a support assembly and a drive assembly. The support assembly is configured to support at least a portion of a body weight of a user. The drive assembly is configured to movably suspend the trolley from the first portion of the support track when the user moves along a first surface and is configured to movably suspend the trolley from the second portion of the support track when the user moves along a second surface separate from the first surface. The power rail is coupled to the support track and is configured to be in electrical contact with a portion of the trolley as the trolley moves along the first portion and the second portion of the support track.

Posture training systems provide hands-free shoulder and back\spine alignment assistance for facilitating correct posture and alignment of the shoulders and spine of an athlete throughout swing or other physical rotational movements, and methods of their use. The posture training systems include vests that provide information during and throughout the rotational movement about spine-tilt angle relative to the ground, plane of the shoulders during torso rotation, perpendicularity between the spine and a line drawn between the shoulders, as well as departures from or maintenance of any of the initial parameters.

A muscle activity output system includes: a muscle activity database configured to hold movable part attitude information and muscle activity information in such a manner that the movable part attitude information and the muscle activity information are linked to each other; and a processor. The movable part attitude information indicates an attitude of a movable part of training equipment. The muscle activity information indicates a muscle activity of each of muscle sites of the exerciser. The processor is configured to acquire the movable part attitude information while the exerciser is moving the body along the trajectory, acquire current muscle activity information for each of the muscle sites based on current movable part attitude information of the training equipment and the muscle activity database, and output the current muscle activity information for each of the muscle sites.

A positioning system includes a golf ball and a mobile terminal. The golf ball includes a battery and a transmitter configured to operate with electric power supplied from the battery and transmit a radio signal to outside of the golf ball. The mobile terminal includes a receiver configured to receive the radio signal from the golf ball and a processor configured to measure the position of the mobile terminal, and to measure the position of the golf ball based on the strength of the radio signal received by the receiver at two or more points at which the measured position of the mobile terminal differs.

Provided is a weight exercise apparatus. The weight exercise apparatus includes an exercise main body in which movement occurs according to the user's weight exercise, a sensor module detecting movement of the exercise main body, and a processor configured to control a UI unit to display a UI element indicating an exercise state of a user corresponding to the detected movement on a UI screen, wherein the sensor module includes a first laser sensor comprising a first measurement accuracy and a first measurement frequency to detect weight setting of the exercise main body when the weight plate is in a stationary state and a second laser sensor comprising a second measurement accuracy lower than the first measurement accuracy and a second measurement frequency higher than the first measurement frequency to detect movement of the weight plate when the weight plate is in a moving state.

A computer-implemented method for determining a target situation in an athletic event. Positional information including the relative positions of a group of selected participants is initially received from a tracking system, and the aggregate motion of the selected participants is detected in real-time using the positional information. The target situation may be determined to have occurred when a change in the aggregate motion occurs in accordance with a predetermined characteristic during an initial time interval.

Presented is an apparatus and system for an artificial turf system. The artificial turf system includes a backing layer having a plurality of fibers extending therefrom. The artificial turf system further includes a plurality of impact sensors located at least partially on, in, and/or beneath the backing layer, wherein the plurality of impact sensors are operable to detect a force or pressure applied to the backing layer.

An indoor, stationary, bicycle training device that provides advantages over conventional designs of exercise bicycles is provided. The stationary bicycle may include a tilting/pivoting mechanism to orient the indoor bicycle to simulate descending or climbing. The indoor bicycle may include flexible and resilient frame elements to support the indoor training device to move side-to-side under some riding situations thereby simulating the side-to-side swaying motion of an outdoor bicycle under the same riding situations. The indoor bicycle may include several combinations of frame adjustments to provide configurable dimensions of the indoor bicycle to adjust the frame to properly fit the rider, which may be adjusted based on corresponding dimensions of a user's outdoor bicycle. Still other aspects of the stationary bicycle device may aid in creating an “outdoor” feeling while using the device.

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.
