METHOD AND COMPOSITION FOR MOTOR TRAINING OF AN INDIVIDUAL

In the motor training of an individual, a motor action to be trained is first selected. This motor action can comprise any movement, such as a walking movement, in particular a running movement, a stroke movement, a throwing movement and the like.

The purpose of the selected motor action to be trained is to ensure that the individual can perform this action faster, with more strength, greater power or longer, and the like.

In the usual training, for example, the selected motor action is performed repeatedly under varying load. On the one hand, for training a stroke movement, the motor elements of the individual active in the action, such as arm and back muscles, can be trained by allowing these muscles to contract and relax a number of times under load from additional weights.

Thus, the strength of the affected muscles will be increased.

In addition, the relevant motor elements can be trained for speed and endurance by performing the relevant striking movement frequently and quickly.

In general, such training will indeed lead to an improvement of the motor action in question, that is to say an ability to perform this motor action at a higher speed, longer and / or with greater strength and power.

The object of the invention is to improve a method of the type described in the preamble such that the effort to be made by the individual in training the selected motor elements efficiently leads to the desired result. That is, the aim is to make the best possible use of training work.

This object is achieved in the method according to the invention as characterized in claim 1. As a result, the training work to be performed with the training device is accurately adapted to the conditions prevailing when performing the motor action to be trained. Thus, the training work is performed in the working conditions of the motor elements as they operate in performing the motor action. An optimal training result is thus achieved.

Preferably, the training device is adjusted and the individual is instructed such that the involved motor elements are activated with a higher power than the desired power. The involved motor elements will develop in accordance with this requested higher power, so that this action could also be carried out with a higher power when performing the motor action.

If the training comprises successively loading and unloading the motor elements, the measure as set out in claim 3 is preferably applied. The intended rhythm can for instance be equal to the rhythm in the execution of the motor action, but can also be higher, so that ultimately the motor action can also be performed with a higher rhythm.

According to a further development, the measure of claim 4 is applied. In this way, a number of properties of the relevant motor elements can be trained, such as strength, speed and power. Depending on the setting of the variations, the different aspects are emphasized.

The measure of claim 5 is preferably applied. Thus, an accurate adaptation of the training work to the results in performing the action can be obtained, so that an optimal result of the training work can be achieved.

The invention also relates to and provides an assembly for motor training of an individual. This assembly according to the invention is characterized in claim 6. The control device processes the data collected by the measuring device from the sensors in such a way that the training device can be adjusted therewith. For example, when training the sprint, the strength and speed with which the individual pushes off with his legs on a surface will be determined. The training device will then be adjusted such that the movements to be performed by the individual on this device are well related to those performed during the sprint. For example, the frequency of movement of the leg muscles can be adjusted according to that occurring during the sprint. The force exerted thereby can be adjusted in accordance with that which also occurs in this sprint.

In a suitable embodiment of the invention, as characterized in claim 8, the measuring device comprises a track in an upper surface from which the sensors are incorporated. As noted previously, these sensors can detect the contact force and velocity of an individual moving across the career.

An assembly according to the invention can be designed in many different ways, for all motor actions to be trained. Depending on the performance expected of the individual, a suitable assembly of measuring device and training device can be selected.

The invention will be further elucidated in the following description with reference to the attached figure.

The device shown in the drawing is a preferred embodiment of an assembly according to the invention for motor training of an individual.

This assembly is particularly utilized for training an individual's leg muscles.

The assembly comprises a running track 1 on the top surface 2 of which a person 3 can perform a sprint. The career 1 is provided with a number of 1014796 4 sensors, with which relevant motor parameters such as speed, distance, pushing force and the like can be measured.

Speedometers 4 are placed at regular distances along the raceway 2, each of which can determine instantaneous speeds.

Furthermore, the runway in the top surface 2 is provided with sensors 6 which cooperate with a transponder 5 which can be carried by the person 3. With the aid of this transponder 5 and sensors 6 co-operating therewith, an accurate position determination of the person on the career can be obtained. The accuracy is preferably of the order of one centimeter.

Not visible, but per se in an obvious manner, sensors are further incorporated in the top surface 2 of the runway 1 for detecting applied force. The data from the sensors for determining the applied force and the positioning sensors and the speed meters supply their measuring signals to a central computer 8, with which the measuring data can be analyzed.

The device is further provided with a starting signal 7, which may for instance be a lamp. For example, if the reaction speed and the acceleration capacity are to be measured, the starting signal can be generated by means of the computer, on which the person 3 starts a sprint.

The course 1 preferably has a length of a few tens of meters, for example 30 meters. This length is sufficient to determine sufficient data about the sprint capacity of persons 3, as is required, for example, in football.

Instead of determining maximum performance for sporting purposes, the career can also be used to measure motor activity in rehabilitation. In combination with the to be described

101473S

5 training with the training device 15, the rehabilitation process can be optimized.

According to the invention, the measurement data collected in the computer 8 are used in this exemplary embodiment 5 for adjusting the training device 15. This training device is here a so-called leg press, which device is intended for training leg muscles in particular. The leg press 15 comprises a carriage 16 that can be moved back and forth on a frame 14, on which a chair 17 is mounted. A footrest 19 is mounted on an upright part of the frame 14.

The person 3, while using the device 15, sits on the chair 17 and rests his feet against the footrest 19.

The leg press shown here is a training device known per se and therefore does not need to be described in detail. It only needs to be noted that a number of weights 20 are coupled in the vertical part of the frame 14 to the carriage 16 via a cable 24 which runs over a number of cable pulleys.

When the carriage 16 is pushed off by stretching the legs of the footrest 19, the weights 25 are lifted, so that this movement takes place under load of these weights 25. The load is adjustable by varying the number of weight elements.

The device 15 is further provided with handles 18 attached to shoulder supports, which the person 3 holds during training.

Sensors 30 are integrated in the footrest 19, which can determine the applied force. In this embodiment, the force exerted by the left leg and right leg can be measured separately. The measuring signals are supplied via a measuring line 20 to the computer 8 for processing. Further connected to the computer 8 is a displacement sensor which measures the displacement of the carriage 16 on the chassis 14.

The assembly according to the invention is further provided with a control unit 23, in this case one

1 014? SS

6 includes display 21 and speakers 22. The person 3 is activated on this screen 21 and via these speakers 22.

As noted above, for example, the measuring force of the person 3 and his speed of movement were determined during the measurement on the career 1. The weight of the weight 25 to be used in the subsequent training is then calculated with the aid of the computer 8, and signals are then given via the screen 21 and the speakers 22 to determine the rhythm in which the test subject has to push the carriage 16 back and forth. At the same time, the force exerted on the footrest 19 is measured, so that a good comparison of the training work with the measured value is achievable. Of course, the values determined on the course 1 and the values determined during the training can be stored in the computer 8, so that after a certain period an analysis of the progress is possible. By regularly repeating the measurements on career 1, a good insight into this course can be obtained.

The computer 8 may be programmed to instruct the person 3 on the training device 15 to perform smooth movements or a sprint-like movement, alternately loading the left and right legs while training. The signals will continue for a certain time, for example to train the stamina.

The specific way in which the signals are delivered depends on the intended training. For example, in addition to a fitness training, a strength training can be done, the efficiency of which can be very high, through the feedback with the data obtained on the career 1.

The different possibilities of the training courses are compiled in training programs that are executed under the control of the computer over a certain period of time.

1014796 7

As previously noted, the method and apparatus according to the invention can be used for sport-specific training. However, the invention is also very useful for rehabilitation, in which the progress of a rehabilitating person can be accurately monitored and the training can each time be adapted to progress as shown by measuring on the career 1.

In addition to the measurement of the force exerted by the feet on the footrest 19, 10 other measurements can also be used to further improve the quality of the training. For example, it is possible to perform knee angle measurements, so that the individual differences in physique of the persons to be trained and the resulting different relationship between the muscle strength and the force measured with the footrest 19 can be validated.

It is noted that the device described here, comprising the running track 1 and the training device 15 only relates to a possible application of the invention, namely for the training of the leg muscles in particular.

However, the invention can be used for training any desired muscle or muscle group, whereby the most efficient training takes place by applying the invention. For example, it is also possible to train arm, chest and back muscles, which are necessary for the throw-in of a ball in football. In that application, the measuring device can for instance be designed optically, in order to measure the speed of the throw-in movement. The muscles in question can then be trained on a per se known training device of the type "lying pull-over". In a manner similar to what has been described above, the training device is adjusted so that the training takes place under conditions corresponding to the measured throw-in, so that the muscles concerned can be trained under those conditions of speed and strength.

Likewise, the invention can be used to train muscle groups that are effective in performing a tennis hit, or a wave hit and the like. Also the "duel strength" which is important in football and can be characterized as rotating the upper body against a resistance, can be suitably trained with the invention. All these and corresponding applications, thus coupling the measurement of a particular motor action to be trained with the training of that motor action itself, whereby the person concerned trains under conditions that correspond to those prevailing during the execution of that motor action. are covered by the attached claims.
