A ground-effect footplate against which a user applies plantar force and moves their foot in 3D across all seven lower-extremity biomechanical axes to accomplish specific as well as global ambulatory objectives related to lower extremity performance improvement, injury prevention and rehabilitation. A device comprising at least one articulating leg connected to a ground-effect footplate and a surface for a user to position against. The device can be used in conjunction with software to create virtual ambulatory environments that mimic GRFVs and cause moments of force that initiate muscular activations that substantially mimic human ambulation, and can couple those movements with non-functional movements in order to improve ROM, speed, strength, and proprioception.

Anchored HydroResistance Speed Training is a running speed training apparatus and training method which is used/done underwater. The apparatus is used to firmly stabilize a floating person's hips while they carryout sprinting mechanics in a maximal rate of force development manner against the resistant environment of the water they are submerged in. The rationale is to enable water-resisted maximal rate of force production training using sprinting mechanics, where this otherwise is not feasible due to the lack of anchoring to a sturdy surface. The apparatus provides the necessary anchoring of a person to an affixed object and stabilizes the waist, iliac crest, anterior iliac spine, and thoracolumbar regions, without restricting limbs, thereby allowing the primary ranges of motion involved in sprinting. The base of the apparatus is firmly affixed to the floor of pools by way of a suction cup base or by being permanently installed into a pool floor.

A method of exercising includes positioning a foot of a user onto a pedal of an exercise device. The pedal is pivotably connected to a pair of supports forming a triangular base and has a neutral position relative to a pivot axis of the device. The method includes applying a first force to the pedal to rotate the pedal about the pivot axis in a first direction, toward a first support. The method includes resisting movement of the pedal toward the first support with a resistance mechanism of the device. The method includes applying a second force to the pedal to rotate the pedal about the pivot axis in a second direction, opposite the first direction, toward a second support and away from the first support. The method includes resisting movement of the pedal toward the second support with the resistance mechanism of the device.

A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The weight training apparatus allows for weight training without weights. The weight training apparatus may provide a more effective and safer mechanism for training than conventional techniques.

An electric adjustable magnetic control damper comprises a force applied unit, a magnetic control unit, a driving unit, and a control unit; a driving rod drives the force applied unit displaced linearly, and a screw sleeve for the screw sleeve to displace linearly and for the screw rod and the magnetic ring to be rotatable, the magnetic control unit has a fixing seat able to displace linearly, and the fixing seat has a the permanent magnet, the driving unit has a motor and a gear train, the control unit can input the required damper value to drives the motor to rotate; whereby the motor and the gear train drives the fixing seat displaced, and create a required gap between the permanent magnet of the fixing seat and the rotor of the magnetic ring to create eddy load for being dampers of axial displacement of the driving rod and rotation of the rotor, and the damper achieves the effect of fitness exercise.

The various devices and systems herein include oropharyngeal exercise devices having a pump bulb with a bulb body having a flow restriction structure with a restricted configuration in which the flow restriction structure is configured to restrict the flow of fluid through the lumen such that the user must apply a force to increase the flow of the fluid. Other devices include containers and/or lids thereof with the bulbs attached to or integrated therein.

An exercise device is provided, including: a main body, two fan wheels and a magnetic resistance assembly. The main body includes an axle disposed thereon. The two fan wheels are connected to the axle and rotatable relative to the main body. The magnetic resistance assembly includes two magnetoresistive rings disposed respectively on the two fan wheels and around the axle, a magnetic unit and a controlling unit. The magnetic unit includes two magnetic portions respectively corresponding to the two magnetoresistive rings. The controlling unit includes a lever rotatably disposed on the main body at a pivot point, and the magnetic unit and an operating portion are disposed on the lever and located by two opposite sides with respect to the pivot point. The pivot point and the axle are eccentrically arranged.

An adjustable exercise apparatus is an apparatus that engages both halves of an antagonist muscle group during the extension and retraction of specific movements and exercises. The apparatus includes a base frame, a first track, a second track, a crossbar, a first resistance-piston system, a second resistance-piston system, a first lockable mount, and a second lockable mount. The base frame stabilizes the upright orientation of both the first track and the second track along the ground. The crossbar reinforces the position and the orientation of the first track and the second track with each other. The first resistance-piston system and the second resistance-piston system provides an adjustable resistance to a variety of movements and exercises throughout use. The first lockable mount and the second lockable mount secures the desired position of the first resistance-piston system and the second resistance-piston system along the first track and the second track, respectively.

A multi-functional modularized exercise apparatus including a bracket, a seat, a power module, at least one exercise module, and a control system is provided. The seat is disposed on the bracket. The power module is securely disposed on the bracket and is located outside the seat. The at least one exercise module is disposed on the power module and connected to the power module. The control system is electrically coupled to the power module, and is configured to adjust a resistance of the power module and adapted to switch the power module to an active mode or a passive mode. An external force is applied to the at least one exercise module and is transmitted to the power module to overcome the resistance of the power module.
