The present invention describes an electromechanical exercise machine that simulates the inertia and weight of a mass in Earth's gravity field and allows a user to move said simulated mass in the primary degrees of freedom of a traditional barbell free-weight system, with or without the use of various accessories.

Systems and methods for hypoxia delivery are provided. An apparatus for providing intermittent normoxia and hypoxia intervals includes a breathing component, a normoxia fluid source, a hypoxia fluid source, a valve, and a control system. The valve is configured to disrupt flow from at least one of the normoxia fluid source and the hypoxia fluid source and the control system is configured to cause the at least one valve to switch between delivery of fluid from the normoxia fluid source and the hypoxia fluid source while maintaining positive pressure at the breathing component.

Systems, methods, and computer-readable mediums for generating, by an artificial intelligence engine, an exercise program comprising a first user energy score, wherein the method comprises generating, by the artificial intelligence engine, the exercise program including an exercise plan including a plurality of exercises. Each respective exercise is associated with user energy consumption metrics based at least on a metabolic equivalent of task (MET) value, and based on the user energy consumption metrics, the first user energy score is associated with the exercise program. The method includes receiving data pertaining to a plurality of users. The data includes physical activity goals the plurality of users desires to achieve. The method includes determining second user energy scores for the physical activity goals, and based on the first and second user energy scores, assigning, by the artificial intelligence engine, at least a subset of the plurality of users to the exercise program.

Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks formed parallel to each other along first axis, a second track disposed on the pair of first tracks, and moving along the first axis, and formed along second axis, a hand holder disposed on the second track, and moving along the second track, and on which at least one of hand and arm of a user is held, a stopper for a track disposed on the pair of first tracks for limiting a movement range of the second track, and a stopper for a holder disposed on the second track for limiting a movement range of the second pair of first tracks, wherein the first axis and the second axis are disposed with an inclination.

An exercise system includes a workout server. An active workout session is created for a user on the workout server. An exercise information is collected for a user at a first exercise device and a second exercise device. The exercise information is tracked to the active workout session and maintained on the workout server. This allows a user to maintain a workout session across multiple devices.

Sensor data is collected from a sensor monitoring a tension generating device of an exercise machine. The sensor data is analyzed to determine whether the sensor data is within a specification. In the event the sensor data is not within the specification, an error stop mode is entered for the tension generating device.

An upper and lower body push and pull exercise machine with a rotatable one directional resistance mechanism and adjustable angle having a movable user support frame having a forward end and a rearward end and the rearward end is pivotable relative to the floor, an angle adjusting mechanism, movable lower body user supports having a foot support platform and a shin support pad operatively connected to the movable user support frame; movable upper body user supports having a gripping handle operatively connected to the movable user support frame, a linkage assembly operatively connected to all of the user supports, a rotatable one direction resistance mechanism operatively connected to the upper and lower body user supports for creating resistance to the exercise motion of the user supports, and a resistance mechanism drive assembly operatively connecting all of the user supports to the rotatable one direction resistance mechanism.

An electric treadmill includes a motor and a motor driving circuit. The motor driving circuit is operable to control electric current flow from a positive electrode through the motor to a negative electrode to drive the motor. The motor driving circuit has a switch path connected between the positive electrode and the negative electrode. The switch path has a resistance element and a switch element connected in series. When the motor driving circuit receives power, the switch element will be switched to a disconnected state, so that the resistance element is inactive. When the motor driving circuit does not receive power, the switch element will be switched to a connected state, so that the resistance element becomes a load between the positive electrode and the negative electrode for consuming power generated by the motor when the endless belt is driven to rotate by an external force.

System for mechanically assisting rehabilitation of a patient. The system includes: a manipulator having at least five degrees of freedom and defining a free end; a limb support for supporting a limb of the patient, and secured relative to the free end of the manipulator; a force sensor operatively connected to the limb support to allow measuring input forces applied by the patient; and a processor communicatively connected to the force sensor, the manipulator, and a memory store which defines a scale factor. The processor is configured to control operation of the manipulator to move the limb support, and further configured so that responsive to receiving an input force measurement from the force sensor, the processor determines an applied force as a function of the input force and the scale factor.

A treadmill includes a frame. A running belt is coupled to the frame so that the running belt is adapted for rotation relative to the frame. At least one sensor is adapted for collecting parameter information regarding the experience of a user of the treadmill. The parameter information is selected from the group consisting of the user's heart rate, total expended calories, stride length, stride force, cadence, pace, distance, resistance level, incline level, carver count, carver cadence, step count, ground contact time, relative position within a race, and relative position on the treadmill. The treadmill also includes at least one light source that is adapted to selectively communicate information to an instructor relating to the parameter.
