The air pressure systems comprise a chamber for receiving at least a portion of a user's body. Pressure in the chamber can be changed to adjust force on the user's body. Described herein are various methods and related structures for sealing a user into a pressurizable chamber. Also described herein are various methods and related structures for changing the shape and/or height of the chamber. Described herein are various types and configurations of chambers and support structures for chambers. Also described herein are various methods and related systems for treating various conditions using the differential air pressure systems, including but not limited to obesity, cardiac disease, multiple sclerosis, cerebral palsy, or Down Syndrome.

A basketball training apparatus includes a shot completion sensor, a condition sensor, and a computer. The shot completion sensor determines whether a shot goes through a basketball hoop. The condition sensor senses a physical condition of a basketball shooter. The computer is in communication with the shot completion sensor and the condition sensor, and has a processor for calculating shot completion percentage as a function of the physical condition.

A functional electrical stimulation system and method is provided, offering coordinated and natural movements for people or animals with motor system damage, which includes: at least one electrical stimulation device delivering electrostimulation signal to form dynamic stimulation curves through at least one stimulation channel by electrodes, at least one main processor, which communicates with a communication unit, with a high voltage generator and with a current controller; at least one sensing device bi-directionally connected to the electrical stimulation device, the sensing device processes and transmits the information to predictively stimulate according to the user needs; and a computational device bi-directionally connected to the electrical stimulation device having computational device with a display screen, a configuration unit and a communication unit allowing information exchange with the electrical stimulation device.

An exercise device having a stowed configuration and a deployed configuration, in which in the stowed configuration, the exercise device is aesthetically pleasing and suitable for most rooms due to front and side panels that hide the framing of the exercise device, and in the deployed configuration, the side panels are opened to expose the arms, which can be deployed, moved up and down to adjust the height, and used to perform exercises based on a pulley system. Pneumatic cylinders may be operatively connected to the pulley system to provide the resistance for the exercises. Handles having gas actuators may be operatively connected to the pneumatic cylinders to adjust the resistance.

An interactive exercise system includes a mechanical support system and a display module held by the mechanical support system. A force-controlled motor is attached to the mechanical support system and a reel is driven by the force-controlled motor. The interactive exercise system also has a handle graspable by a user and includes a cord extending between the reel and the handle. The handle or other accessory can be attached by a quick release mechanism. Force applied through the force-controlled motor is based at least in part on detected user force input.

The described embodiments relate to systems, methods, and apparatuses for providing linear tension to multiple areas of a person to improve training and exercise. The tension can be applied by cables supplied from cable spools that are attached within a resistance assembly. The resistance assembly can be worn as a backpack during exercises, thereby providing a portable means through which tension can be provided to the body. The cables from the resistance assembly can be attached to appendages such as the wrists and legs of the person, and the tension provided by the cables can be adjustable. For instance, the tension can be made non-uniform across the body in order to improve the person's ability to maneuver in situations where there is an imbalance of force on the body.
