The present invention relates to a unit, an apparatus and a method for measuring the maximum muscular strength, and more particularly, a measurement unit detachable to the muscular exercise device, a measuring device comprising the unit, and using the apparatus The present invention relates to a method of measuring the maximum muscular strength by sensing the load vertically upward from the weight body.

Modern people enjoy a variety of exercises to revitalize their minds and bodies and to improve their health. Among them, weight training is a representative exercise for improving muscle strength. In constructing such weight training program, it is essential to evaluate the individual's strength, and in general, the maximum strength (1 RM; 1 Repetition Maximum) The strength is measured by measuring.

Conventionally, the maximum muscle strength has been measured directly by allowing the subject to lift various weights, but such a method is particularly likely to cause muscle damage or an increase in blood pressure, especially for beginners, the elderly, and women. The measurement took a lot of time.

To solve this problem, select the weight that the subject can comfortably carry out, perform the repetition as much as possible, check the number of times, and indirectly obtain the maximum strength from the equation of 100-(repeat times × 2) =% 1RM. Although the phosphorus method has been proposed, problems of muscle damage and long duration still remain, and there are many variations in accuracy depending on the selected weight of the subject, the number of repetitions, and muscle fatigue.

In recent years, although the maximum strength measurement by the isokinetic exercise equipment has been carried out, such equipment is not only very expensive, but even if the muscle strength is measured by the isokinetic equipment, when you actually want to exercise using the exercise equipment, There is a contradiction that the maximum strength for strength setting must be remeasured either directly or indirectly.

The present invention has been made to solve this problem, the guide rod, coupled to the guide rod of the muscle exercise machine including a weight body having a through-hole for the guide rod and a wire connected to the uppermost weight of the weight body is provided with a load cell By using a removable maximum strength measuring unit, the load cell detects the upward load from the weight generated when the weight is lifted, thereby making it possible to measure the maximum strength of various body parts in an easy and inexpensive manner. For that purpose.

The maximum strength measurement unit of the present invention for achieving the above object is a maximum strength measurement unit detachable to the muscle training apparatus including a guide rod, a weight having a through-hole for the guide rod and a wire connected to the uppermost weight of the weight body. A clamping member for clamping the guide rod; A load cell coupled to the lower portion of the clamping member; And a load transmitting member coupled to the lower portion of the load cell to transmit a load vertically upward from the weight generated when the weight is lifted, to the load cell. It is coupled to the guide rod to contact, characterized in that the load cell detects the vertically upward load from the weight.

Since the maximum strength measurement unit of the above configuration is detachable to the guide rod of the strength exercise mechanism by the clamping member, it can be used in combination with several strength exercise instruments for measuring the strength of each body part with only one measuring unit. The cost is reduced.

In addition, by sensing the vertically upward load from the weight generated when the weight of the muscle exercise device is lifted, it is possible to easily measure the maximum strength by only one trial. The time required for the measurement is also shortened without causing damage or the like.

In the present specification, the term "vertical upward load from the weight generated when the weight is lifted" means that when the subject applies a force to lift the weight of the muscular exercise device to measure the strength, It refers to the force acting in the vertical direction upwards to the weight body, and more precisely, the weight set on the muscular exercise device from the force acting in the vertical direction so on the weight body by the force exerted by the subject. It refers to the force minus the weight of the body weight state.

According to the above configuration of the present invention, a clamping member for tightly coupling the maximum strength measurement unit to the guide rod of the muscle exercise mechanism, the load to be in contact with the highest weight body of the strength exercise mechanism when the maximum strength force measuring unit is coupled to the guide rod By including a transfer member and a load cell that receives and senses a vertically upward load from the weight through the load transfer member, it is possible to implement a detachable unit in which the maximum strength can be easily measured.

In addition, the maximum strength measurement unit of the present invention to achieve the above object, in addition to the above configuration, the load transmission member is characterized in that the height can be adjusted.

"Load transfer member is capable of height adjustment" means that the height of the load transmission member itself can be adjusted, as well as to implement the height adjustment by the auxiliary members of various lengths coupled to the load transmission member In the latter case, contact with the highest weight will be an auxiliary member coupled to the load transmission member.

According to the above configuration, for example, in the case of the muscle exercise mechanism further protruding vertically upward from the periphery of the through hole of the uppermost weight body so that the guide rod penetrates, each of the muscle exercise mechanisms has various protrusions. By adjusting the height of the load transmitting member appropriately according to the height of the hole, the maximum strength measuring unit is coupled to the muscle exercise mechanism, so that the load transmitting member overcomes the height while clamping the guide bar exposed from the position higher than the protruding hole. Since the contact with the highest weight body is made possible, for example, the length of the load transmission member is short and coupled without contact with the highest weight body, so that the loads vertically upward from the weight body cannot be properly transmitted to the load cell. Can be prevented, and it is easy to be used for muscle exercise equipment of various heights of protrusion holes. This will allow you to measure your maximum strength.

In the above configuration, the maximum muscle strength measuring apparatus includes a maximum strength force measuring unit of any one of the maximum strength force measuring units.

That is, according to the method of measuring the maximum strength of the present invention, since the maximum strength measurement device that is detachable from the guide rod of the strength exercise device is used, the various strength exercise devices for measuring the strength of each body part with only one measurement device are used. It can be used in combination to reduce costs, and it is also possible to easily measure the maximum strength by only one trial by detecting the load vertically upward from the weight generated when the weight of the muscular exercise device is lifted. As a result, there is no need for repeated trials, and the time required for the measurement is also shortened without causing muscle damage or the like.

In the present specification, the term "upright load from the weight body generated when the weight body is lifted and transmitted through at least a part of the maximum muscle strength measuring apparatus" means that the weight of the muscular exercise device is measured by the subject for strength measurement. When a force is applied to lift the sieve, it refers to a force that acts vertically upward on the weight, and more precisely, the force exerted on the weight by the force exerted by the subject. The force is referred to as a force obtained by subtracting the weight of the weight body state set in the muscular exercise device.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(Example)

1 to 3 illustrate a maximum muscle strength measuring unit 30 and a clamping member 10 and a sensing member 20 constituting the unit 30 according to an embodiment of the present invention, respectively.

First, the clamping member 10 of the exemplary embodiment of the present invention shown in FIG. 1 serves to couple the maximum muscle force measuring unit 30 (FIG. 3) to the muscle exercise mechanism 40 (FIG. 4), and the fixing unit 10. (11), the moving part 12, the insertion part 13, the adjusting part 14 and the coupling part 15.

The clamping member 10 is inserted into the guide rod 46 (FIG. 4) of the muscle exercise mechanism 40 through the insertion portion 13 to be in close contact with the fixing portion 11, and then rotates the adjusting portion 14 to move. The part 12 is moved in the horizontal direction to be in close contact with the guide bar 46, and is configured to firmly clamp the guide bar 46 by the fixing part 11 and the moving part 12. The sensing member 20 is fixedly coupled to the lower side of the shape as shown in FIG. 3.

The sensing member 20 shown in the front view in FIG. 2 serves to sense the vertically upward load from the weight body 41 (see FIG. 4) of the muscle exercise mechanism 40, and the load transmission member 21. , The load cell 22, the coupling part 23, and the cable 24.

The load transmission member 21 and the highest weight body 41 which is the uppermost of the weight body 41 of the muscle exercise mechanism 40 when the maximum muscle force measuring unit 30 is coupled to the muscle exercise mechanism 40. It is in contact with each other, and is applied to the load cell 22 by receiving a vertical upward load from the weight body 41.

It is preferable that the load transmission member 21 be able to adjust the height, and the configuration such that the length of the load transmission member 21 itself can be adjusted such that the height is adjusted by rotating the load transmission member 21. Of course, it is to include a separate auxiliary member (not shown) of various lengths coupled to the load transmission member 21 and optionally adjust the height by combining the auxiliary member of the appropriate length, the latter In this case, it is an auxiliary member coupled to the load transmission member 21 that comes into contact with the uppermost weight body 41, and the auxiliary member receives a load vertically upward from the weight body 41 to receive the load transmission member ( 21 will be delivered to the load cell 22 through.

When the load transmission member 21 is configured to adjust the height in this way, for example, the guide rod 46 penetrates vertically upward from the periphery of the through hole (not shown) of the uppermost weight body 41. In the case of the muscular exercise device 40 further comprising a protruding hole 45 (see FIG. 4), an appropriate auxiliary member is used depending on the height of the various protruding holes 45 for each of the muscular exercise devices 40, or By adjusting the height of the load transmission member 21 and then coupling the maximum muscle force measuring unit 30 to the muscle exercise mechanism 40, thereby clamping the guide rod 46 exposed from a position higher than the protrusion hole 45. While the load transmitting member 21 can overcome the height and make contact with the highest weight body 41, for example, the length of the load transmitting member 21 is short so that it cannot come into contact with the highest weight body 41. From the weight body 41 by The load of the vertically upward it is possible to prevent problems, such as those that can not be properly transmitted to the load cell 22, it is possible to easily measure the one repetition maximum in the weight instrument 40 of the various extrusion hole 45 in height.

The load cell 22 is a gravimetric element that outputs an amount of deformation such as compression or elongation by weight as an electric signal. In the present invention, a compressive force can be measured. As long as the measurement of the vertically upward load is possible, the form is irrespective.

The load cell 22 is formed at the lower side of the clamping member 10 by the coupling of the coupling portion 23 of the sensing member 20 and the coupling portion 15 of the clamping member 10, as shown in FIG. 3. It may be fixed, and the fixing method may be any type, such as screwing and integral, and although not shown, the load cell 22 may be provided with a zero adjustment means, an appropriate casing, etc.

In addition, the load cell 22 includes a power supply unit (not shown) for supplying power to the load cell 22 through a cable 24, and a display unit 50 which shows an output value from the load cell 22; 5).

Now, referring to FIG. 4, which is a schematic diagram of a state in which the maximum strength measurement unit 30 according to an embodiment of the present invention is coupled to the muscular exercise device 40, the maximum strength measurement method according to the present invention will be described.

Typically, the strength exercise device 40 is a plurality of weights 41, the grip 44, the weight body 41 is provided so that a person can lift the weight 41 to the hands, feet, forearms, ankles, etc. Wire 42 connecting the grip 44 and a pin 43 for setting the weight state of the plurality of weight bodies 41, a guide rod 46 for guiding vertical movement of the weight body 41, Through-holes (not shown) formed in the respective weight bodies 41 so that the guide rods 46 penetrate, and are formed vertically upward from the periphery of the through-holes of the uppermost weight body 41 of the weight bodies 41. It includes a protrusion hole 45 and the like surrounding a portion of the rod 46.

In order to measure the maximum muscular strength according to the present invention, first, the weight body 41 is set to the minimum weight state so that even a person with weak muscular strength can be lifted. It may be carried out after coupling to (40).

Typically, the minimum weight state is achieved by not inserting the pin 43 at all or by inserting the pin 43 into the uppermost weight body 41. The reason for setting to the minimum weight state is that the muscle exercise mechanism 40 Is set to a weight that is too heavy for the subject to lift and causes the subject to exert a force on the weight 41, the weight 41 will not be lifted even if the subject is exerting maximum muscle strength. This is because there is no force transmitted to the load transmission member 21 at all, and therefore, the measurement of muscle strength is impossible at this time.

Of course, even if it is set to a weight state that can be lifted by the subject, the force applied to the load transmission member 21 vertically upward from the weight body 41 is the strength exercise mechanism ( 40) is only the force minus the set weight, so even if the subject exerts the maximum force, the force itself transmitted from the load transmitting member 21 and sensed by the load cell is considered to be the maximum muscular force of the subject. Since there will be no number, it can be seen that the numerical value which must be finally expressed as the maximum muscular power of the subject through the display unit 50 or the like should be calculated in consideration of the weight of the weight 41 which was set at the time of the muscular strength measurement. .

If only this is taken into account, it is not necessary to set only the minimum weight state as described above, as long as it is set to a weight state that the subject can lift, and according to the subject the other appropriate weight state, for example, male , Even if it is set to a different weight state according to a woman, an elderly person, a child, or the like, or set to the same weight state for everyone, but set to a predetermined weight state obtained by, for example, an experimentally obtained maximum muscle strength. It is a good thing.

In this way, the weight body 41 is set to a predetermined weight state, preferably a minimum weight state, and as shown in the figure, the maximum strength force measuring unit 30 uses the clamping member 10 to increase the strength exercise mechanism ( 40) to the guide rod 46.

At this time, the clamping member 10 firmly clamps a predetermined portion of the guide rod 46 emerging from the position higher than the height of the protruding hole 45 while the load transmission member 21 contacts the uppermost weight 41. Will be done.

If the maximum muscle force measuring unit 30 is coupled to the guide rod 46 while the load transmitting member 21 is not in contact with the uppermost weight body 41, it occurs when the subject lifts the weight body 41. The vertically upward load from the weight body 41 is applied to the load transmitting member 21 only after the top weight body 41 is lifted by a distance from which the load transmitting member 21 is separated from the top weight body 41. And a factor that interferes with accurate strength measurement, such as being suddenly hit by the load transmission member 21 and applied, the load transmission member 21 is in contact with the highest weight body 41 in the state of the maximum strength measurement unit ( It is preferable to install 30).

Then, when the subject to apply the lifting force to the weight body 41, the force is transmitted to the weight body 41 through the wire 42, the force in the upward direction perpendicular to the weight body 41 acts And, the force minus the set weight of the force acts vertically upward to the load transmission member (21).

Thus, the force transmitted from the load transmission member 21 and sensed by the load cell 22 is converted into the muscle strength value (maximum muscle strength value) of the subject by the display unit 50 connected through the cable 24 of the load cell 22. The display unit 50 includes a digital display 52 capable of providing various types of information such as an analog method such as an indication needle, a digital method of displaying a numerical value, etc. It is preferable.

In addition, as shown in FIG. 5, the display unit 50 includes a print unit 53 so that the measurement results can be printed, and a power supply unit for supplying power to the load cell 22 (shown in FIG. 5). And amplification unit (not shown) to amplify and output the minute output from the load cell 22, and various menu buttons, function buttons, etc. Accordingly, it is desirable to be able to provide a suitable training program to the subject, and to provide an appropriate selection mode according to a predetermined weight state of the muscular exercise device 40.

Furthermore, the load cell 22 and the display unit 50 may be a wireless communication system other than the wired connection via the cable 24 and the cable 51, and the display unit 50 and the computer (not shown) may be used. It is also a good idea to connect to make use of measurement results in various applications or to provide training online services by connecting to the Internet.

Although specific embodiments of the present invention have been described above, various modifications and changes are possible without departing from the scope and spirit of the present invention. For example, in the present invention, the power supply unit and the print unit included in the display unit may be configured separately from the display unit.

According to the present invention, the detachable maximum muscle strength measuring unit having a load cell and coupled to the guide rod of the muscle exercise device including a guide rod, a weight body having a through-hole for the guide rod and a wire connected to the highest weight body among the weight bodies; By using it, it is not necessary to separately install the maximum strength measuring device in each strength exercise device, thereby reducing the cost for measuring the maximum strength of various body parts and from the weight generated when the weight is lifted. By sensing the load in the vertical direction by the load cell, it becomes possible to measure the maximum muscle strength of various body parts in an easy and inexpensive manner, so there is no risk of muscle damage and it does not take a long time.
