The methods and systems can include matching a user to an available and/or appropriate DAP system. Also provided are methods and systems including performing a workout and uploading performance information to an aggregate database of user information.

There is described an integrated unweighted gait training system having an unweighting system comprising a computer controller; a gait measurement system in communication with the controller; and a display in communication with the computer controller adapted and configured to provide real-time feedback to a user of the integrated unweighting gait training system. The unweighting system may be a differential air pressure (DAP) unweighting system or a non-DAP unweighting system.

A resistance sensing mechanism including a resistance adjusting unit including a holder frame, a locating sleeve disposed above the holder frame, an adjustment screw rod rotatably inserted through the locating sleeve and a screw nut threaded onto the adjustment screw rod and pivotally connected to the holder frame, and a sensor unit including a first linkage pivotally connected with one end to the screw nut, a second linkage having one end pivotally connected to an opposite end of the first linkage and an opposite end pivotally connected to the locating sleeve, a sensor mounted at one of the first and second linkages and a sensible member mounted at the other of the first and second linkages to face toward the sensor. Subject to the linkage relationship between the first and second linkages, the distance between the sensor and the sensible member can be changed, thereby generating a relative sensing signal.

A resistance sensing mechanism includes a resistance adjusting unit including a holder frame, a locating sleeve disposed above the holder frame, an adjustment screw rod rotatably inserted through the locating sleeve and a first screw nut threaded onto a first thread segment of the adjustment screw rod and pivotally connected to the holder frame, and a sensor unit including a linkage pivotally connected to the holder frame, a second screw nut threaded onto a second thread segment of the adjustment screw rod and pivotally connected to the linkage, a sensor mounted at one of the holder frame and the linkage and a sensible member mounted at the other of the holder frame and the linkage to face toward the sensor. Subject to the relative movement between the first and second screw nuts, the holder frame and the linkage relatively biased to change the distance between the sensor and sensible member.

A high knees exercise apparatus includes a base, a driving mechanism, a linkage mechanism and two magnetic resistance. The driving mechanism is located on the base and includes two driving member which is driven swung along arc path. The linkage mechanism is for leading the driving members swung reversely in response to each other. The two magnetic resistance devices are for providing magnetic resistances in accordance with swings of the two driving members respectively.

A system for use in rehabilitation of a target patient is provided. The system includes at least two bicycle devices for use by the target patient and a second operator other than the target patient. The at least two bicycle devices each include pedals. At least one of the pedals may have at least one sensor mounted thereon for monitoring operation of the first bicycle device and the target's condition. A servomotor is coupled to the pedals for providing gear-like resistance or pedal assistance for the at least two bicycle devices. A controller is programmed to electrically couple the at least two bicycle devices to each other.

A weight resistance exercise machine having cable and pulley linkage assemblies attached to a single weight stack. Each cable and pulley linkage assembly, which is independent of the other(s), can be used by one arm or leg during bilateral exercise training (that is, training in which both limbs of a pair are used to simultaneously to lift a weight). A tilt platform and biofeedback assembly display and measure in real-time how much each limb of a pair is contributing to such lifting effort.

A bicycle training system and methods of using the same. The system includes a movement platform that rests on a support surface and supports a bicycle in an upright manner with respect to the support surface. The movement platform includes a support frame having a base and at least one upstanding arm that supportably engages a portion of a frame of the bicycle, a resistance assembly operatively coupled to a portion of a drivetrain of the bicycle that applies varying levels of resistance to the portion of the drivetrain, and a plurality of bushings isolating the base from the support surface. The plurality of bushings are spherical thereby permitting the movement platform to move with respect to the support surface in response to forces applied to the bicycle frame during use of the bicycle training system.

A physical fitness system includes a stand assembly including a stand, a computing device mounted on the stand, and at least one integrated docking station for receiving an exercise device. At least one exercise device is configured to be releasably mounted to the docking station. Upon receiving instructions from a user input on the computing device, the system computer processor is configured to transmit instructions over the network from a system network communication interface to an exercise device network communication interface, and upon receiving the instructions, the exercise device processor is configured to activate a driver in the exercise device to change either the resistance applied to the exercise device or the weight carried by the exercise device.
