Regulating group (20) for adjusting the initial operating position (A) of an interface (11) associated with a gymnastic machine (1) comprising a frame (10); a load group (16) connected to the interface (11) through a respective transmission device (17); a support group (12) designed to carry the interface (11) movable relative to the frame (10); the regulating group (20) comprising a return device (21) suitable, in use, to define, at the initial operating position (A), a stop for the movement of the interface (11) relative to the frame (10); wherein the return device (21) can be connected, in use, to the transmission device (17) through a given coupling (25), so that to each variation in the initial operating position (A) actuated through the return device (21) corresponds a respective given variation in the operating configuration of the transmission device (17).

An exerciser (10) for the sake of training the abdominal muscle group is disclosed, wherein the operator may rotate on his backbone for taking a twisting exercise for his upper and lower bodies in reverse (different) direction; and wherein the exerciser (10) includes a rotating disc mechanism (20) for the lower limb of the operator to stand thereon and swiveled under application of force, a rotating handlebar mechanism (40) for the upper limb of the operator to hold thereon and swiveled under application of force, and a coupling mechanism (30) for synchronically and reversely coupling the rotating disc mechanism and the rotating handlebar mechanism.

A waist twist machine (10) capable of synchronically swinging in different directions employs a synchronic transmission assembly, like a diverting bevel gear set, to synchronically rotate a rotating disc (30) (the position of the user's lower body) and a handle (50) (the hand-gripping position of the user's upper body) in opposite directions so that a double twisting exercise effect of the waist and the abdominal part is achieved by rotating the user's upper or lower body at a minimum angle. Moreover, the synchronic transmission assembly synchronically brings a pendulum (60) in a to-and-fro movement that acts both as a weight to provide an exercise resistance and as a power source to create an inertia swing.

The invention relates to an orthesis for controlling the angle of a limb relative to a second body part to which the limb is connected via a joint such as a hip, elbow or shoulder, which orthesis comprises:

- a first arm rotatably, around a rotation point, connected to the second body part;

- a second arm fixedly arranged to the limb; and

- guide means for providing at least a two dimensional free translation of the second arm relative to the first arm, while maintaining both arms parallel.

In an exercise apparatus having a frame that is adapted for placement on the floor, a pivot axle supported by the frame, a pair of pedal levers, pedals secured to the pedal levers, arm handles connected for motion with the pedal levers and which can utilize a variety of pedal actuation assemblies for generating elliptical motion of the pedal, the stride length portion of the elliptical motion can be increased automatically as a function of exercise parameters such as speed. In addition, the arm handles can be disconnected manually or automatically from the pedal levers

The SKY WALKER machine depicted in the two accompanying Figures, namely TABLE 1 - TABLE 2, is a machine for rehabilitation, relaxation and stretching of the joints, for corrective exercises and various forms of paramorphisms. It is also designed for those with spinal problems, such as scoliosis. This machine allows the user making gymnastic exercise to strengthen the upper body muscles. All exercises practiced are carried out in suspension (without contact with the ground) and are similar to the traditional "Swedish wall bars". The uniqueness and novelty of this machine is the automatic suspension of the user through electrically controlled lifting systems, controlled by a micro-computer and some safety devices.

The SKY WALKER machine can automatically recognize the height of a person with his/her arms raised using a safety bar connected to an encoder and automatically recognizes when this person begins to use it, or when it ends to use it, through a load cell system. This machine has two functions: "lift up and down", that is only lifting, and "lift and go" allowing the user to hang to the rungs by his/her hands, moving his/her hands to take the rungs that approach the user in succession.

An exerciser machine including a base frame, a pole frame and a swivel frame is described. The base frame can have longitudinally a head section and a rear section pivotally coupled with the head section. The pole frame can have one or more extendable poles extending longitudinally between a far end and a near end of the pole frame. A cross bar can be detachably affixed between the extendable poles. The pole frame may be pivotally attached to the base frame. The swivel frame can have one or more side bars having longitudinally a handle end and a pole end. A handle bar may be detachably fixed between the side bars at the handle end. The swivel frame may be rotably attached to the extendable poles to allow rotary movements of the swivel frame in between the extendable poles.

An apparatus that enables one or more people to simulate on land the action of rowing on water, including the simulation of an oar blade entering into and being extracted from water that is moving relative to a boat, and including feedback on rowing performance and technique. The apparatus includes the same fundamental elements as a real rowing boat, with one or two oar handles 6 per person, a sliding seat 4, adjustable footplate 5 and rigging 7 that supports rowlocks. The inertia, momentum and drag of a real boat are simulated using a damped flywheel. The percentage of torque that is transmitted between each oar handle and this flywheel is controlled using magnetic clutches, and is based upon an analysis of the position and angle of each simulated oar blade.
