In a swing exercise machine having a seat, a seat driving apparatus that moves the seat along a locus formed by a combination of a periodic swing motion around an anteroposterior swing shaft and a periodic swing motion around a transverse swing shaft, and a control circuit that can control rotation speed and rotation direction of a motor. The control circuit can switch the rotation direction of the motor, so that the seat can be moved in a reverse direction along the locus. Since the human body is asymmetrical in the anteroposterior direction, the regions of the human body where muscle activities occur when the seat is moved in the reverse direction are different from those when the seat is moved in a normal direction. Thereby, it is possible to vary the effect of the swing exercise on the human body.

Swing exercise machine

An oscillation-type exercise device is provided with a pair of reins on the right and on the left disposed in front of a user seated on a seat portion. Base ends of the pair of the reins are coupled to a pair of extensible mechanisms housed inside the seat portion. Handle portions to be gripped by the user are attached to tip ends of the pair of reins. Each extensible mechanism is configured to change the length of the reins, that is, each extensible mechanism causes the reins to generally extend and retract.

Oscillation-type exercise device

A wedge-shaped tilt provider is attached in contact with the bottom surface of a seat and the upper surface of a seat connection member of a rocking mechanism to set the seat to an initial inclined position relative to a reference position. By setting the seat to a forwardly inclined position from a horizontal position where the seated surface of the seat is set horizontal, the user straddling the seat can increase the amount of muscle activity of his or her rectus muscle of abdomen, or abdominal muscle. Further, by setting the seat to a rearwardly inclined position, the user straddling the seat can increase the amount of muscle activity of his or her back muscle such as paraspinal muscle. With use of a rocking type exercising apparatus having the above construction, a stress of exercise simulating horseback riding is given to the user by changing the position of the seat relative to the reference position by a certain degree of inclination, while rocking the seat which the user straddles, whereby the user is selectively provided with an exercising effect onto a specific site of his or her body.
