An exercise apparatus to enhance muscle recruitment of a user includes a base platform, a rotatable shaft coupled to the base platform, a brake assembly coupled to the base platform and operably connected to the rotatable shaft, the brake assembly having a controller designed to engage and disengage the brake assembly from the rotatable shaft, and a pair of cables with first ends coupled to the rotatable shaft and second ends coupled to a bar. The controller engages the brake assembly with the rotatable shaft to lock the rotatable shaft in a stationary position for a predetermined time to permit the user to perform an isometric movement with the bar. The controller disengages the brake assembly from the rotatable shaft after the predetermined time to permit the rotatable shaft to rotate to permit the user to perform a plyometric movement with the bar.

A respiratory rehabilitation apparatus includes a housing, an adjustment rod provided in the housing to change a pressure load generated during respiration, a pair of stoppers for selectively adjusting respiration pressure, a pair of pressurization-movement parts configured to be pressurized and moved inwards in a longitudinal direction of the housing by respiration pressure during respiration, a pair of elastic members disposed between the pressurization-movement parts and the stoppers, and a pair of diaphragms disposed so as to be in close contact with outer sides in a longitudinal direction of the pressurization-movement parts.

An exercise device for use by persons with limited strength or mobility includes a a frame member situated in an interior area of a body member. First and second upper appendages are coupled to and extend away from upper left right regions of the body member. First and second lower appendages are coupled to and extend away from lower left right regions of the body member. A top appendage may extend away from a top region of the body member. A tension member, such as a tension spring, is situated inside each appendage and is configured to be selectively bent, extended, or otherwise manipulated and is resilient to return to an unbent and retracted configuration. Movement of respective tension members enables a person to exercise, experience the touch sensation, and have feelings of pleasure and enjoyment. A magnet attached to the frame member attracts other magnetic or metal items.

An adjustable resistance exercise machine for providing variable resistance forces on a pull cable extending from the machine. The adjustable resistance exercise machine generally includes a plurality of power springs that may be selectively engaged using a cam mechanism. By engaging springs with different forces, the resistance may be adjusted incrementally as preferred for performing different exercises. The adjustable resistance exercise machine may be connected to various structures, either below or above an exerciser, to allow the exerciser to choose whether to pull the pull cable up or down during exercise.

A resistance system is configured to perform a resistance exercise for an axial base, such as a torso, and a longitudinal member, such as a leg and arm. The resistance exercise helps develop the longitudinal member and axial base by forcing the longitudinal member to pull against different, but constant tension forces, and also forcing the longitudinal member to maintain a proximal distance to the axial base. A short resistance member extends between a foundation mount on the axial base and an intermediate mount on the longitudinal member. A long resistance member extends from the foundation mount, joining with the intermediate mount, and attaching to a distal mount. The short resistance member generates greater tension force than the long resistance member when stretched. The multiple and independent connections made by resistance members create different tension forces for resistance exercises.

A variable stride exercise apparatus may provide a novel linkage assembly and corresponding exercise apparatus suitable for linking circular motion to relatively more complex, generally elliptical motion. Left and right cranks are rotatably mounted on a frame. A foot supporting linkage is movably connected between a rocker and the left and right cranks in such a manner that may provide a variable paths of motion controlled by a user of the apparatus.

An exerciser comprises a first block, a second block, a first torque member, a second torque member, and a damper assembly. The first block has an axle pivotally coupling with the second block. The first torque member is arranged at a first position or a second position of the first block. The second torque member is arranged at a first position and a second position of the second block. The damper assembly couples with the first block and a second block. The forces exerted on the first torque member and the second torque member will increase or decrease the distance between the first torque member and the second torque member.

Apparatuses and methods for an oropharyngeal exercise device. The oropharyngeal exercise device has interchangeable parts comprising complete mouthpieces, complete springs, a housing, a progress gauge, and a stopper. The oropharyngeal exercise device and its interchangeable parts are organized and stored in a standardized kit. The kit allows a patient to take the exercise device on the go and makes home-health treatment of oropharyngeal disorders easier and more accessible. Patients can customize the exercise type and resistance. A variety of mouthpieces also allows patients to perform not only isometric exercises, but also perform dynamic exercises to increase flexibility and range of motion.

A pelvis exercising system including: a movable seat, sized and shaped to support a user by his pelvis; a vertical supporter which supports the seat above the ground; a flexible connector mounted between the vertical supporter and the seat; wherein, the seat comprises a front portion and a rear portion extending upwardly away from a central arch, each of the rear and front portions comprises a length which is long enough to support a front portion and rear portion of the user's pelvis, while not significantly restricting the abdomen and lower back from bending in relation to a sagittal plane of the seat. A sensor positioned to measure movement of said seat relative to a base, wherein the sensor provides measured values of the seat relative to the base to a processor; and the processor controls a device based on the measured values. Related apparatus and methods are also described.
