A self-powered vibration mechanism is provided that can be mounted on an existing pedal shaft yet operates independent from the existing pedal. Mechanical isolation or mechanical decoupling permits transferring the vibrating energy to the foot rather than to the pedal shaft and the bicycle. In another embodiment, a full removable pedal with self-powered vibration mechanism can replace an existing pedal.

An oscillatory respiratory therapy device 100 has an opening 8 to atmosphere through which air passes to the user. The device has a visual indicator 20 including a paper indicator 25 and a dye reservoir 29 mounted at the opening. Before use, the opening 8 is covered by a removable cover strip 21 that prevents air flowing through the opening. The cover strip 21 is attached to the dye reservoir 29 so that the reservoir is pulled against the paper indicator 25 when the cover strip is removed, thereby the device to be used. This causes dye to flow gradually from the reservoir 29 and spread outwardly across the paper indicator 25, which is marked to indicate duration of use.

An improved method of physiotherapy includes loading muscles of a torso of a user with a torque acting substantially about a vertical axis; and the user using an exercise equipment while the torso is loaded with the torque.

An oscillating positive expiratory pressure device includes a housing, a top cover, and an oscillating unit. The housing includes a bottom wall and a surrounding wall. The bottom wall has an inclined enclosing surface extending downwardly and terminating at an opening. The oscillating unit is swingably connected to and disposed within the housing. The oscillating unit includes a swing member, and first and second weighting pieces. The swing member includes a swing arm, and first and second swing blocks connected to the swing arm. The first weighting piece is carried on the first swing block. The second weighting piece is carried on the second swing block. The swing arm is swingable to move the second swing block to block and unblock the opening.

An explosive strength training device is provided. The explosive strength training device includes a cable set, a power box, a resistance motor and a controller. The cable set includes a rubber belt and a movable pulley block connected with one end of the rubber belt, the movable pulley block has a first main pulley disposed opposite to the rubber belt, and allows the pulling force of the rubber belt to pass through the center of the first main pulley. Through the labor-saving structure of the first main pulley, the middle section of the power belt is wound on the upper side of the first main pulley and fixedly sleeved on the positioning rod with the fixed side to form a fulcrum.

The present invention may be embodied as a system or method for dynamically exercising a user's neck muscles. The system includes a headset, an arm attached thereto, a weight, and at least one motor to move the weight, for example, about the arm. The weight may be mounted eccentrically on a radial track that is rotatable by one motor and moved linearly by another motor. The direction of the arm, the distance between an apex of the headset and the weight, the eccentricity of the weight on the axis, and the speed of rotation of the motor are all parameters that can be adjusted by the caregiver or user, either manually or via controlling software.

An exercise apparatus includes flexible elongated members configured for attachment to shoes of a user. Motor assemblies are disposed between the elongated members and the shoes, respectively, and cause the flexible elongated members to oscillate. Rotational drums attached to the flexible elongated members and are configured to rotate the flexible elongated members while the elongated members oscillate.

A running device and method of using the device are disclosed. The device may include a moveable material within an inner chamber of the running device's housing. In operation, a running device may be held in each hand and the runner may thrust both hands downward prior to landing and quickly bring the devices to a vertical stop after landing. Bringing the devices to a vertical stop may cause the moveable material to collide with the housing and increase the force exerted by the runner on the ground. A delay component may delay the peak force exerted by the material against the housing so that the translation of that force to the ground coincides with the peak force that the runner would have exerted against the ground in the absence of the devices.

An expiratory, vibratory therapy device (100, 200 300, 400) includes a compliance meter (104, 204, 304, 404) having a cylinder (110, 210, 310, 410) with a piston (111, 211, 411) movable along its length. The piston is urged by a spring (116, 226) to one end of the cylinder. The opposite end of the cylinder has an air inlet (120, 123, 219) normally closed by a springloaded occluder (129). The occluder (129) is moved to open the air inlet when the patient exhales in the prescribed manner. This allows some air to enter the cylinder and enables the piston to be displaced. The piston is coupled to a flag (106, 206, 306, 406) visible to the patient. When the correct number of prescribed breaths have been made the piston displaces the flag to indicate completion of the therapy.

Systems and methods for an exercise apparatus are provided and include a flexible elongated member, a binding apparatus, and a motor assembly. The binding apparatus is attached to the flexible elongated member and has a clamping mechanism configured to secure a shoe of a user of the exercise apparatus to the flexible elongated member. The motor assembly is disposed between the shoe and the flexible elongated member and is configured to cause the flexible elongated member to oscillate.
