A timing device comprising a housing, a controller within the housing, and a shock sensor connected to the controller and within the housing. The controller receives a first signal from the shock sensor when the shock sensor detects a first shock or vibration. The controller receives a second signal from the shock sensor when the shock sensor detects a second shock or vibration. The controller starts a timer in response to receipt of the first signal. The controller stops the timer in response to receipt of the second signal.

The invention provides an apparatus for playing a game, the apparatus comprising; a moveable portion configured to emit a moving beam of radiation; a detector and a device arranged to be worn by a player, wherein the device is configured to send a signal to the detector in response to interaction with the beam.

A method and apparatus for physical exercises and, in particular, for training the movements jump and squat from spot for training. The method and apparatus can have the jump and squat motions follow into a continuous alternating sequence as a response to a passing via a training spot in the same continuous alternating sequence of a lower obstacle, obligating the performance of jump, and of the upper obstacle obligating the performance of squat.

An agility ladder has a plurality of rungs including first and second rungs. A left link assembly has ends pivotally attached to left ends of the first and second rungs, and a right link assembly has ends pivotally attached to right ends of the first and second rungs. The left and right link assemblies each include first and second links having equal lengths, with the first and second links joined at a link pivot joint which allows the first and second links to form an angle between them of less than 180 degrees.

The present invention discloses an interactive exercising apparatus. The invention describes an exercising apparatus that includes a long rope connected to a rubber ring at one end and to a handle at the other end. The rope also consists of a small plastic two way swivel to connect the rubber ring with the rope and avoid rolling of the rope while the exercising apparatus is being rotated during exercise. The invention is designed for two to forty participants that require a leader and players and is described as a rotating large group jump rope that comes with more than twenty variations. The invention is provided to promote active and healthy lifestyle, to get participants moving, having fun and develop fitness skills.

A device for an exercise apparatus includes a linear adjustment system and a sensor coupled to the linear adjustment system. The linear adjustment system varies a length of the device thereby fixing the loading interface of the exercise apparatus at any one of a plurality of functional positions in the functional range of the loading interface. The sensor measures the force exerted on the linear adjustment system. A correlating mechanism is used to correlate the force exerted on the linear adjustment system with the force exerted on the loading interface. The device allows exercisers to exert high or maximum loads in any one of a plurality of positions throughout their entire range of motion without first passing through a weak range of motion.

An example exercise mat is disclosed. The exercise mat comprises at least one sensor to detect an article on the mat and obtain a force measurement exerted by the article through a movement; and a communications unit to communicatively connect the mat to a computing device and provide the force measurement to the computing device. The computing device performs a plurality of calculations based on the force measurement.

A luminous jumping ball includes a connecting rod, an ankle ring, and a roller. The ankle ring is fixedly connected to an end of the connecting rod, another end of the connecting rod facing away from the ankle ring is rotatably connected to a rotatable sleeve, the rotatable sleeve is fixedly connected to the roller through a spring, two ends of the spring are fixedly connected to an end of the rotatable sleeve and an end of the roller, respectively, and the spring, the rotatable sleeve, and the roller are coaxially arranged. The connecting rod and the roller are connected through the spring. When the roller collides with the ground, the spring acts as a cushion to prevent damage caused by rigid connection during the collision, thereby increasing a service life of the jumping ball and a smoothness of rotation of the roller.
