An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

The neurological rehabilitation system described includes at least visual display components, a robotic platform, a sensor array, and a neurological rehabilitation controller. The neurological rehabilitation controller controls the robotic platform based on outputs from the sensor array and generates at least a real-time visual simulation displayed using the visual display components. The generated real time visual simulation simulates a task as part of an enhanced task-oriented therapy for a patient undergoing neurological rehabilitation. The robotic platform is a physical structure that interfaces with the patient and facilitates the patient's movement of various body parts (e.g., arms and/or legs) in synchrony with the real-time visual simulation to perform a virtual task over time. The robotic platform also receives control instructions from the neurological rehabilitation controller, which articulate the platform and apply resistance force to the patient interface(s) to create a more realistic task experience.

An isometric, dynamic isotonic concentric and dynamic isotonic eccentric motorized guidance exercise apparatus for human muscle development is provided. The exercise apparatus comprises a frame, an electric motor, the electric motor including an output shaft and secured to the frame, a drive guidance assembly, the drive guidance assembly secured to the frame and connected to the output shaft; at least one tactile feedback interface member, the at least one tactile feedback interface member secured to the drive guidance assembly; a weight plate, the weight plate secured to a limb of the human body, the limb positioned at the at least one tactile feedback interface member and wherein energizing the electric motor actuates the drive guidance assembly, the drive guidance assembly induces a motion in the at least one tactile feedback interface member, the limb engages the at least one tactile feedback interface member and the limb actuates the weight plate.

A rowing machine provides resistance to both pushing and pulling motions of both the upper body and lower body. A linear sliding seat that moves in a longitudinal direction is connected to a flywheel to provide resistance to back and forth motion. A handle arm is also connected to the flywheel to provide resistance to back and forth motion. The flywheel creates cyclical back and forth motion of the seat and handles for the user to push and pull with the arms and legs. The handle arm and seat may be linked together, and then one or the other linked to the flywheel, providing synchronization between the handlebar, carriage and flywheel.

A device for therapy or exercise includes a frame, a base at least partially supporting and extending from the frame, a user support moveably coupled to the base and positioned adjacent the frame, a foot crank system coupled to the frame, a hand crank system coupled to the frame, and a motor coupled to at least one of the foot crank system and the hand crank system. The motor selectively powers the foot crank system and the hand crank system and is operable in an active mode and a passive mode.

The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.

A training apparatus for fencing, the training apparatus including: (a) a movement mechanism having an extended state and a retracted state, the movement mechanism adapted to be coupled to a support structure on a first end thereof; (b) a target platform, the target operationally coupled to a second end of the movement mechanism; and (c) a computing component, the computing component electronically coupled to the movement mechanism and configured to control movement of the movement mechanism between the extended state and the retracted state.

A system and method for optimizing a person's muscle group performance thru modulating the arm, leg, and core muscle exertion rate based upon the exerciser's metabolic and geographic data. The system uses real-time measurement gathering and storing of physiologic parameters from humans during physical exercise activity and the geographic data of the exercise activity to determine information for optimizing the exerciser's physical exercise performance of the basic working muscle groups in the rider's arms, legs, and core. The system broadcasts to exercisers information including, but are not limited to: a) the current condition of their monitored muscle tissue, b) which muscle groups the riders should modulate and change their level of energy output during the exercise activity, and c) level of energy exertion at which riders should be employing at that moment in the relevant working muscle groups to optimize their physical exercise performance.

An upper limb rehabilitation training system in two-person standing type and an application method thereof are provided. The upper limb rehabilitation training system includes an upper limb rehabilitation training platform, two weight-reducing suspending support structures arranged oppositely, and two standing frames arranged oppositely; the upper limb rehabilitation training platform includes an all-in-one computer which includes a computer and a touch display screen, and a periphery of the touch display screen is provided with a grating structure; the upper limb rehabilitation training platform is provided with a two-person interactive upper limb training module including two control handles, a virtual training prop and a virtual training scene. The two control handles are suspended from the two weight-reducing suspending support structures, respectively; the grating structure is configured to identify the control handles and positions thereof. The computer controls the two control handles to perform game interaction with the virtual training prop.

A fitness bar housing free-moving weights. The movement and speed of the weights can be controlled by a flow impeder. Other embodiments are described.
