Procedure for Muske ⁷ training and device for performing the procedure.

The invention relates to active "resistance" training or on active "resistance" exercises »as well as on an embodiment of a device for performing a such trainings.

There are different training methods known in the book "The Principles of Exercise Therypy" by M.D.ß / rdner et alt 6, Bell and Sons, Ltd., London 1957, described. "Resistance" training attacks the leg Limbs an external force to the forced Counteract muscle contraction · Over the course of a The muscles develop when the tension is in the period of time Muscles by the opposing or external resistance force is enlarged, an increase in their strength and a abnormal enlargement (hypertrophy).

This external force can either be dynamic or static are fed.

aO9811 / 0321

The person exercising works in the pall of the static feed usually opposed to a relatively immovable object. This can be a wall, for example, or an opposite and be equally strong link. In either case, the muscle does not move after its initial contraction; one such isometric contraction assists the maximum performance exerted by the muscles in a short period of time 1st. It is believed, however, that isothrasal contraction causes irritation to the joints and a curvature of the Itoochen can cause »as well as little growth brings in dynamic strength or strength as it does not allow maximum performance over a natural trajectory of a body part is exercised.

In the dynamic case, the exercising person works against a relatively flexible force. Such a force can be generated by weights, springs, or by a pressure exerted by H _P nd by a physiotherapist. A yielding force enables the muscle to be trained over the entire range of motion of the muscle. However, the muscle is not equally strong over its entire range of motion. While the muscles, due to the mechanical advantage of the limbs with which the muscles are connected, are physiologically strongest when fully extended, the exerciser is strongest, or may be the greatest, in the middle range of motion Exercise powers. Advantageously, the resistance should

- 2 aO9811 / 0321

change force according to the force exerted by the exerciser Person going out. At the beginning and at the end of the movement there is in Hegel a lower counteracting force than that advantageous, which is needed in the middle course. Such changes in the resistance are not without further achievable with weights or springs - Eire such Change can be achieved through the hand pressure of the physiotherapist, which counteracts the practicing person who However, the forces occurring here are not easily measurable It is desirable that the resistance be measurable so that the exerciser's port step can be recorded can

It is therefore the object of the invention to provide a method and a device for training the movement of the person exercising over the entire range of motion of the Muscle counteracts and that delivers any desired resistance force that can be adjusted in the course of the practicing person can be overcome; this resistance should also be in equilibrium with the force exerted by the person to avoid bouncing or Avoid "unbalance effects".

It is also a device to be created, the evenly and repeatedly regulated constant power, unregulated absorbs variable performance and maximum performance ■

Furthermore, a device is to be created which has an immediate bftres reading of the dynamic force that τοη the exercising person is exerted in the course of their movement.

A speed of movement should also be provided that is constant and therefore for the person exercising Predictable and safe, as well as safe and favorable exercise conditions for optimal dynamic neuro-musculature training creates.

Finally, a device is to be provided that "earths the movement." of the exercising person, whereby the guided movement is concentric to the axis of the joint with which the Limb and the trained muscle work together, and can also run in a plane with this muscle.

According to the invention, the problem posed is achieved by that the speed up to which the person uses the device to adopt muscle strength along the path can move to a predetermined maximum along the entire Path is limited · The device for executing the

Is even. The manometer is calibrated so that it divides the pressure in pounds ζ 453.6 gr) by the mechanical gain or growth of the joint system, so as to create a real display of the force exerted on the operator at the point of application of the force will.

It is noted that the hydraulic system controlled the pig. only allows a constant acceleration of the piston 106 in both directions. In certain circumstances it is desired to enable other movements su. For example, it may be desirable to “allow the person practicing” with a Press constant acceleration in one sighting and quickly and without forcing in the other direction squeeze out a bending movement. Ss can also be upset on the other hand » enable the exercising person to do so with constant soling Pull in a Biohtung su and quickly without force ι

is at one end at the common connection point the inlet of the regulator valve 120, the outlet of the regulator valve 138 and the one outlet 108A of the cylinder 108 and its other end is connected to the valve 200. A bypass line 204 iat with one end at the common connection point the inlet of the regulating valve 116, the outlet of the regulating valve 136 and the other Auelaaaes 108 B of the cylinder 108, and the other end thereof is connected to the valve 200. A return line 206 is with one end at the common connection atelle of the outlet the regulating valve 132 but also constitutes constants Flow and the inlet of the regulating valves 13 and 138 are connected. The different combinations the four-way valve 200 are as follows

1. Line 202 coupled to line 206 allows piston 106 to move freely to the left;

2. Line 204 coupled to line 206 allows piston 106 to move freely to the right;

3 Both lines 202 and 204 coupled to line 206 allow free movement in both Directions;

This yentil is set aui 'a maximum bridge, s.B 20 pounds (9072 gr) should the exercising person attempting to exert a force, that crosses this bridge in the system becomes no the excess power consumed in acceleration. This arrangement limits the resistance that the machine offers the exercising person and eliminates "overtraining" the person exercising

The shut-off valve 130 is also in line with the inlet of the Heguller valve 132 to form the constant Flow and is with a quick-closing device Mistake. This arrangement enables the piston 106 to be stopped in any position of its movement and further allows the exercising person to grasp an isometric grip sn against which they can apply any force they may can generate, can exercise.

in turn ait a gear 26β is connected. The gears 266 and 266 are each in singular engagement as a gearwheel 68 because it is attached to a shaft 270. A tooth log 272 is attached to the shaft 270 and can be driven either clockwise or counterclockwise by the person exercising. The shaft 270 corresponds to the shaft 42, which is shown in Figure 2 and the toothed disk 272 corresponds to the toothed disk 46. The clutch 256 transmits a rotation oaent only in the counterclockwise direction. The coupling 263 transmits a rotation only in a clockwise direction.

Therefore, if the exercising person does not rotate the shaft 270, none of the clutches 256 or 265 will be pressed in la rotates clockwise, the shaft 258 old the "limit speed" is rotated counterclockwise, and the clutch 256 is engaged to the son corner 250 via the gear 254, the clutch 256, the shaft 258, the gear 260 and the Zalrrxad with the Coupling shaft 270. Regardless of which exerts a torque on the exercising Pereon the shaft 270, the son corner 250 rotates at this constant speed and exerts a counter-working auxiliary L _a from st. Similarly, if the exercising person turns shaft 270 counterclockwise, shaft 264 is turned clockwise at the limit speed , and the clutch

As soon as a clutch is engaged, the system cannot be accelerated by the person exercising, which affects the Drive characteristics of the motor and the worm drive is due in only one direction. Everyone about that Limit speed applied force sum Sin. move a clutch counteracts a fieaktlonakraf t of the mechanical system, while the system is relatively slowly gives way under the suggested force. When the force being guided decreases, e.g. when the exercising person pushes the When they stop moving, the system stops moving.

The system thus sets the action of the exercising Peneon kinetic resistance, which is precisely dependent on the force that it supplies, and it is momentary at the moment always a little less than the force that the person is supplying.

Additional features can be introduced into the mechanical system. The motor is connected to the voltage source 274. A switch 276, in series with the motor, enables the motor to be turned off, creating an isometric handle ^{11.

If "a limit force the resistance has been supplied renigetens _t slept the relay and schalteb the motor 252 a. Two magnetic couplings 286 and 288 are arranged in a row between shafts 258 and 264. As a result of the torque that can be transmitted to the coupling 286, a variable resistor 290 can be controlled, which is connected in series with a voltage source 292. The maximum torque that can be transmitted by the clutch is controlled by a variable resistor 294 connected in series with the clutch 283. These clutches start to slip at the maximum torque and any force in excess of such a maximum that is exerted by the person exercising is consumed during acceleration.
