Electromechanical rehabilitation of a user can include receiving a pedal force value from a pedal sensor of a pedal; receiving a pedal rotational position; based on the pedal rotational position over a period of time, calculating a pedal velocity; and based at least upon the pedal force value, a set pedal resistance value, and the pedal velocity, outputting one or more control signals causing an electric motor to provide a driving force to control simulated rotational inertia applied to the pedal.

A rowing exercise apparatus has a linkage assembly that is provided in two boxes. One box includes a forward frame member, a crank rotatably mounted on the forward frame member, and a forward portion of a seat supporting link operatively connected to the crank. Another box includes a rearward frame member, a rocker link pivotally mounted on the rearward frame member, and a rearward portion of the seat supporting link operatively connected to the rocker link. The linkage assembly is made suitable for use by rigidly connecting the two frame members to one another and by rigidly connecting the two portions of the seat supporting link to one another. At least one bracket is rigidly interconnected between the two portions of the seat supporting link. One such bracket is welded onto a rearward end of the forward portion of the seat supporting link to underlie and directly support a proximate end of the rearward portion of the seat supporting link. A seat is mounted on the seat supporting link for movement through at least one elliptical path as the linkage assembly moves through cycles relative to the rigidly interconnected frame members.

Portable modular training systems are described herein. In one aspect, a modular training system includes a system container including a container front, a container rear, a container first side, a container second side, a container bottom, and a container top, defining a container cavity, and an exercise structure comprising a platform connector with a vertical support bar coupled to an interior surface of the system container and a horizontal bar coupled to the vertical support bar and extending external to the system container via an aperture defined by the system container.

A multi-stimulation neurorehabilitation assistant system, comprising a support unit, an audio stimulation unit, an acupoint stimulation unit, an electronic stimulation unit, a training unit, a display and optical frequency-flashed stimulation unit, and a control unit. The support unit includes a rotatable top-side portion over the top of the user's head. The audio stimulation unit includes two speakers. The acupoint stimulation unit includes several acupoint agents. The electronic stimulation unit includes several electronic stimulation agents. The training unit can sense user's own movements to output measurement signals. The display and optical frequency-flashed stimulation unit can be switched between a display mode and an optical frequency-flashed stimulation mode. The control unit electrically connected with the speakers, the acupoint agents, the electrical stimulation agents, the training unit and the display and optical frequency-flashed stimulation unit, so that users can obtain multiple stimulations at the same time during rehabilitation.

An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

Disclosed is a multifunctional exercise chair for body stretching, comprising a wheelchair frame body, wherein a mounting frame is detachably mounted on an end of the wheelchair frame body away from the driving rear wheel and located under the seat cushion, a pedal gear is rotatably mounted at a bottom of the mounting frame and a pedal is provided thereon, a hand crank gear is rotatably mounted on a top of the mounting frame and a hand crank handle is provided thereon, a rotating shaft is provided between two driving rear wheels; a driven gear is fixedly mounted on the rotating shaft, a supporting chain gear is mounted on the mounting frame and arranged adjacent to the pedal gear, and the hand crank gear, the pedal gear, the driven gear and the supporting chain gear are wound and connected by a transmission chain.

An adjustable elliptical trainer is disclosed, which includes a body, a sliding rail, a connecting piece and a movement mechanism. The sliding rail has one end rotatably connected to the body around an axis and other end detachably connected to the body by the connecting piece along a longitudinal extension direction of the sliding rail. The movement mechanism includes a sliding part matched with the sliding rail, and the sliding part is provided on the sliding rail and is slidable along the sliding rail. The axis is perpendicular to the longitudinal extension direction of the sliding rail, a first connection point is provided at a joint between the connecting piece and the sliding rail, and a second connection point is provided at a joint between the connecting piece and the body, the connecting piece is configured to be movable relative to the sliding rail and/or the body.

A pedaling exercise device includes a rotation mechanism configured to pivotally support a rotation shaft to allow rotation, a pair of cranks having first ends connected to both ends of the rotation shaft of the rotation mechanism, respectively, a pair of links having first ends rotatably connected to second ends of the cranks, respectively, and having second ends provided with wheels, respectively, a pair of pedal portions connected to the links along a longitudinal direction of the links, respectively, a rolling surface connected to a first end of the rotation mechanism on a user side, and a restriction portion configured to restrict separation of the wheels from the upper surface of the rolling surface in a case where the first end of the rotation mechanism is lifted such that the rotation mechanism is erected in a state where a second end of the rotation mechanism is grounded.

A method includes receiving electronic content via a network, the electronic content comprising an exercise class, and receiving user data associated with a user participating in the exercise class using an exercise machine. The method also includes generating an executable control for a user interface based at least in part on the user data, and providing the executable control, via a display of the exercise machine, while the user is participating in the exercise class. In such a method, the executable control is operable to modify a parameter of the exercise machine while the user is participating in the exercise class.
