A stationary exercise cycle. The stationary exercise cycle includes a frame, a crank rotatably connected to the frame, a driven wheel rotatably connected to the frame, and a frame stiffener. The frame includes a down tube and a fork. The crank and the driven wheel are in operative communication via a continuous flexible member. The frame stiffener is connected to the down tube and the fork and encircled by the continuous flexible member.

The specification relates to a mobile exerciser. The mobile exerciser can include a mobile exerciser frame; a foot rest assembly attached to the mobile exerciser frame having a working position and a stored position; and a pedal assembly attached to the mobile exerciser frame having a working position and a stored position. The mobile exerciser can be converted from a push mode to a pedal mode by moving the foot rest assembly into a stored position and the pedal assembly into a working position and the mobile exerciser can be converted from a pedal mode to a push mode by moving the foot rest assembly into a working position and the pedal assembly into a stored position.

A bicycle crankarm provided with an electric/electronic system, including a battery power unit, a processor having a standby mode and a running mode, and a wake unit that emits a wake signal of the processor, wherein the wake unit is completely supported by or in the crankarm.

A rehabilitation and exercise system can include a base. A static device can be coupled to the base and configured to provide isometric exercise for a user by receiving static force from the user to facilitate at least one of osteogenesis or muscle hypertrophy for the user. In addition, a dynamic device can be coupled to the base and configured to provide a dynamic exercise for the user by being moved by the user to facilitate at least one of osteogenesis and muscle hypertrophy for the user.

A compressible material is provided for use with athletic equipment and apparel for enhancing the effects of physical exercise for a person. The material can include one or more compression members that extend from shoes, insoles for shoes, exercise gloves, wraps for exercise equipment, exercise mat or floor covering, headbands, socks, exercise garments, free weights and sports helmets. The compression members can be made of one or more of rubber, thermoplastic rubber, foam rubber, polyurethane rubber, silicone rubber, thermoplastic resin and thermoplastic elastomer. Positioning the compressible material such that it is between the user and any surface for example when exercising, requires the person to maintain balance while performing the exercise by using other muscles that would not ordinarily be used during the exercise, and provides proprioceptive feedback to the person's central nervous system.

An exercise device, such as a bicycle or spinning bike, includes a frame, a first set of crank arms connected to a rotary shaft supported by the frame and having an imaginary rotational axis stationary with respect to the frame. A second set of crank arms is mounted eccentrically with respect to the rotational axis of the rotary shaft. A second shaft is coupled to the second set of crank arms such that rotation of the second shaft generates vibrations of the crank arms in the second set of crank arms.

The invention relates to a bicycle ergometer, composing at least one pedaling device for a user and a vibration unit, wherein: the vibration unit has at least ore main shaft (12), which is driven directly or indirectly by a motor (54) and has an eccentric disk (6) fastened thereto; the eccentric disk (6) is rotatably coupled to a connecting rod (1); and the connecting rod (1) transmits, by means of a rod eye (1a) disposed on opposite from the eccentric disk (6), the vibrations to the bearing (29) of the pedaling device such that the vibrations are applied substantially exclusively to this bearing (29) in the vertical direction.

A fitness equipment and an automatic oxygen-generating fitness equipment are disclosed. The fitness equipment comprises a power unit, a sensor unit and an oxygen-generating assembly. The power unit comprises a belt drive turnplate, a belt and a magnetic wheel. Rotation of the belt drive turnplate drives the belt to operate so that the magnetic wheel is driven to rotate. The sensor unit is adapted to detect the belt drive turnplate and generate an activation signal when the belt drive turnplate is rotating. The oxygen-generating assembly comprises a control unit, a motor and an oxygen generator. The control unit is configured to receive the activation signal from the sensor so that the motor is activated to drive the oxygen generator to operate. The control unit may also control the equipment to switch between an oxygen-generating mode and a non-oxygen-generating mode.

A crank apparatus includes a crank arm having at least one cavity on one of the surfaces of the crank arm, at least one thin material layer embedded within the at least one cavity and having an exposed outer surface, and at least one sensing element attached to the outer surface of the thin material layer. The crank arm is manufactured of a material with non-uniform strain characteristics, the thin material layer is manufactured of a material with uniform strain characteristics, the crank arm is adapted to be deformed by a force, the thin material layer is adapted to be deformed correspondingly with the deformation of the crank arm, the at least one sensing element is adapted to measure the corresponding strain of the thin material layer to measure the force applied on the crank arm. A bicycle and a stationary exercise bicycle equipped with the crank apparatus are further provided.

A method of calibrating a crank arm-mounted power meter includes receiving an angle measurement from a first sensor disposed on a crank arm, the angle measurement corresponding to an angular orientation of the crank arm. A predicted load measurement is then calculated based on the angle measurement and weight data for the crank assembly including the crank arm and stored in memory. A load measurement corresponding to a load on the crank arm is obtained and a zero offset value is then calculated by determining a difference between the predicted load measurement and the load measurement. Power calculation logic for determining power applied to the crank arm is then updated using the zero offset value.
