Description

  The present invention relates to a grip detection mechanism adaptable to exercise equipment, an exercise equipment including the grip detection mechanism, and a method of using the exercise equipment.

  Conventionally, in the measurement of grip strength, the grip force is measured by measuring the load between the changing handles by the grip of the spring-only principle by gripping a pair of oppositely held handles. With regard to a measuring instrument of grip strength, in Patent Documents 1 and 2, a grip portion provided with a closed space is formed by a flexible member, and the grip strength is measured by measuring the pressure of the closed space which changes by gripping this grip portion. The configuration is disclosed.

  By the way, it has been reported that training by management of grip strength can prevent blood pressure drop or high blood pressure. It is considered that this can be used not only for measuring grip strength, but also for exercise equipment that uses grip strength as a guide for such training and the like. However, the conventional grip strength meter has a problem that it can not be adapted to use for such training and the like.

  Further, according to Patent Document 3, the short diameter in plan view of each of a pair of outer shells formed of a metal plate or a synthetic resin material or the like into a bowl shape having a substantially oval shape in cross section and an arched cross section. A hinge is provided at the center of one side of the direction, and the shell is overlapped with the recess facing each other, and the hinge is rotatably connected with a hinge pin (therefore the main body is bivalve or musical instrument Has a structure close to the castanet.) One end of the support is fixed at the center of the concave part of one shell, and the support is erected, and an elastic plate of appropriate length molded into the other end of the support. And fix one end of the elastic plate to the inner side (recessed portion) of the other shell with the approximately central portion of the convex surface fixed and the shell opened with the appropriate size at the opposite peripheral edge of the hinge portion A sounding-type fingertip function recovery exerciser is disclosed.

  Holding this exercise tool for recovery of the finger tip function with the palm and repeating the squeezing and loosening operations repeatedly makes the circulation of the whole body as well as the palm and the fingertip active, and restores hand numbness and grip function due to high blood pressure In addition, the elastic plate is pressed and deformed every time the grip is in use, and a light sound is emitted, the sense of use can be consciously conscious, and it can be used without getting tired for a long time It is said that.

  However, in the sound-production-type fingertip function recovery exerciser described in Patent Document 3, adjustment of the hardness of the elastic plate is difficult, and the elastic plate is too hard to be grasped unless it is deformed. There was a problem that was not soft enough to exercise properly. In addition, it has been troublesome to replace the elastic plate that has been fixed each time the adjustment is made.

  In addition, there has been a problem that it is necessary to exercise for a long time using this exercise tool for recovering the function of the fingertip for the improvement of hypertension.

It is not intended to be limiting.

The grip strength detection mechanism 1 of the present invention comprises a grip portion 12 formed of a cylindrical flexible member;
Sealing members 13 and 16 which seal both ends of the grip portion 12 to form a deformable sealed space surrounded by the grip portion 12;

In the grip portion 12, there is provided a battery case having flanges 11A, 11A at both ends,
Both ends of the grip portion can be pressed against the flanges 11A and 11A by the sealing members 13 and 16, respectively, and the grip portion 12 can be sealed by the sealing member (claim 2).

Further, the control unit 31 sets a predetermined pressure equal to or less than the detected pressure as a reference grip force based on the pressure detected by the pressure sensor according to the maximum grip of the user gripping the grip 12;
The display unit may be configured to indicate that it has been detected that the grip of the user gripping the grip has reached the reference grip (claim 3).

  The reference grip strength may be set within a range of constant height and width with respect to the pressure corresponding to the reference grip power, and the reference grip power may be displayed on the display unit (claim 4).

  Furthermore, the present invention includes an exercise tool 10 having the grip strength detection mechanism 1 of the present invention described above (claim 5).

  In addition, as a method of using the exercise tool 10 including the grip strength detection mechanism 1 (claims 1 to 4), the grip portion 12 is gripped for a certain period of time with the reference grip force and gripped. Exercise to lower blood pressure can be performed by repeating releasing (claim 6).

Also, the control unit 31
Based on the pressure detected by the pressure sensor 28, set and record a reference grip strength by the pressure below the detected pressure,
As a method of using the exercise tool 10 provided with the grip strength detection mechanism 1 (claims 3 and 4) as the reference grip power indicated by the pressure detected in the enclosed space,
Set the standard grip to approximately 30% of the maximum grip of the user,
The grip portion 12 is held by holding for 2 minutes while holding a constant force of about 30% of the user's maximum grip power, then holding the grip for 1 minute and releasing it twice with the left and right hands a total of 4 times The blood pressure can be lowered by repeating (claim 7).

  According to the grip strength detection mechanism 1 of the present invention, it is suitable for use as an exercise tool used for various trainings and the like.

  Further, according to the grip strength detection mechanism 1 of the present invention, the movable part can be significantly reduced compared to the case where the grip strength is detected and measured by the principle of spring only, so that the structure can be simplified and the size and weight can be reduced. . Further, by holding the pressure sensor 28 and the like on the sealing member 16, the whole can be miniaturized and simplified as a substantially rod-like cylindrical shape, and the usability can be remarkably improved by these.

Embodiment FIG. 1 shows an exerciser 10 provided with a grip strength detection mechanism 1 according to an embodiment of the present invention. The exercise tool 10 provided with the grip strength detection mechanism 1 is generally formed in a substantially cylindrical shape, and the central portion in the direction of the central axis of the cylinder serves as the grip portion 2, and cylindrical end portions 3 at both ends of the grip portion 2 , 4 are provided respectively. Here, although the grip portion 2 is formed in a barrel shape having the largest diameter at the central portion, it may be made to have a constant diameter in the central axis direction instead, so that the diameter is smallest at the central portion Alternatively, the cross-sectional shape of the outer peripheral side surface in the direction along the central axis may be a shape that conforms to the hand as a corrugated shape.

  In the grip strength detection mechanism 1, the switch portion 5 is disposed substantially at the center of the end face of one end portion 4, and the switch portion 5 is turned clockwise to turn on the power supply. An operator of the power switch is configured. Further, the switch portion 5 is pivoted counterclockwise to remove the switch portion 5 and replace the battery. Further, in the grip strength detection mechanism 1, the display unit 7 is provided on the end face of the other end 3. The display unit 7 is a bottomed cylindrical transparent or semi-transparent member having a low peripheral wall height, and is fitted to the inside of the top cap 16 so as to cover a wiring board 23 described later. Here, as shown in FIG. 8, in the display unit 7, a circular display unit 7A corresponding to the light emitting diode 8A installed at the center of the wiring substrate 23 is formed at the center, and further, the display unit 7A at the center The circular and triangular display portions 7B to 7M corresponding to the light emitting diodes 8B to 8M are formed concentrically and at regular equiangular intervals (about 30 degrees) around it. Here, in the display units 7B to 7M with this constant isometric interval, only one display unit 7B of these display units 7B to 7M is formed in a triangular shape with the tip disposed on the side of the central display unit 7A. , And the other display parts 7C to 7M are formed in a circular shape so that the display part 7B can be easily distinguished from the other display parts 7C to 7M.

  Further, in the present embodiment, the shapes of the other display parts 7C to 7M are circular, but the shapes of the other display parts 7C to 7M are not limited to the circular shape and can be easily distinguished from the display 7B. It is good also as what can be made, for example, other shapes, such as a rectangle.

  As shown in FIG. 2, the grip strength detection mechanism 1 having the above configuration holds the grip strength by holding and pressing the grip section 2 with the display section 7 on the upper side so that the display section 7 can be visually confirmed. It can be detected and measured, and furthermore, the detection result of the grip strength can be used to execute training.

  FIG. 3 is a cross-sectional view taken along the line A-A 'of FIG. The grip strength detection mechanism 1 includes a cylindrical battery case 11 having flanges 11A and 11A at both ends. Further, the grip portion 12 is formed in a cylindrical shape by a flexible material such as silicon resin so that the diameter of the central portion is maximized, and the battery case 11 is arranged in the axial direction inside the grip portion 12; The end on the end 4 side of the grip 12 is pressed against the flange 11A of the battery case 11 by the end cap 13 which is a cylindrical sealing member located at the end 4 using a screw 14 to seal And the end on the end 3 side of the grip 12 is pressed against the flange 11A of the battery case 11 using the screw 17 with the top cap 16 which is a cylindrical sealing member located at the end 3 And sealed. Thus, the grip strength detection mechanism 1 is formed by the battery case 11 and the grip portion 12 as a deformable sealed space 18 whose inside is cylindrical.

  The grip strength detection mechanism 1 is between the flange 11A of the battery case 11 and the top cap 16, between the flange 11A of the battery case 11 and the end cap 13, between the screw 14 and the end cap 13, the screw 17 and the top cap An O-ring 19 which is a flexible sealing material made of synthetic rubber, for example, silicon resin, is disposed between the space 16 and the like as appropriate, thereby preventing air leakage from the sealed space 18. A through hole 11B is provided in the flange 11A of the battery case 11 on the end cap 13 side, and a check valve 21, for example, an umbrella valve 21 is provided on the closed space 18 side of the through hole 11B. It is comprised so that the air omission etc. in long-term leaving can be prevented, preventing the sudden flow in and out of the air in 18 [FIG. 3 (A)]. The O-ring 19 and the umbrella valve 21 may be omitted if the sealed space 18 can be sufficiently maintained for practical use.

  Further, the wiring board 23 is disposed at the end on the top cap 16 side. Furthermore, the switch portion 5 is removed inside the cylindrical battery case 11 so that the dry cell 24 can be stored, and the switch 5 side electrode of the dry cell 24 stored in this way is wired via the switch portion 5 Battery terminals 25 and 26 are provided so as to be connectable to the substrate 23 and to connect the electrode of the dry cell 24 on the wiring substrate 23 side to the wiring substrate 23. Thereby, the grip strength detection mechanism 1 removes the switch portion 5 to accommodate the dry cell 24, and drives the electronic circuit provided on the wiring substrate 23 by the dry cell 24.

As shown in FIG. 3B, the through hole 27 is provided in the top cap 16 on the wiring substrate 23 side of the battery case 11, and the through hole communicating with the through hole 27 is provided in the flange 11A. The wiring board 23, a pressure sensor 28 is provided so as to close the transmural hole 27. Here, the pressure sensor 28 is formed such that the end on the flange 11A side extends from the outer periphery of the cylindrical shape, and this cylindrical portion is disposed so as to fit into the through hole 27; An O-ring 29 which is a sealing material is disposed between the through hole 27 and the through hole 27. As a result, the grip strength detection mechanism 1 effectively avoids air leakage and detects the pressure in the enclosed space 18 by the pressure sensor 28. Here, the pressure sensor 28 is a so-called semiconductor pressure sensor 28, but various pressure sensors can be widely applied as needed.

  As the pressure sensor 28 used in the present invention, for example, a piezoresistive semiconductor pressure sensor using piezoresistive effect is preferable.

  A sensor chip used for a piezoresistive semiconductor pressure sensor is a silicon chip with a substantially concave silicon layer with a cross section downward provided with a small cavity (this cavity serves as a diaphragm (pressure receiving part)) by etching on a glass pedestal. A piezoresistive portion (strain gauge) is formed on a thin silicon surface which is overlapped and which corresponds to the roof portion of the hollow.

In the present invention, in the piezoresistive semiconductor pressure sensor, the pressure in the sealed space 18 increases as the grip 12 gripped by the user is recessed and the volume in the sealed space 18 decreases. When the thin silicon surface on the diaphragm is bent, the electric resistance value of the piezoresistor (strain gauge) changes, and this change is converted into an electric signal (processed and amplified by an electronic circuit).

  Further, in the grip force detection mechanism 1, a drive circuit for driving the pressure sensor 28, a control circuit by a computer for processing the detection result of the pressure sensor 28, light emitting diodes 8A to 8M corresponding to the display portions 7A to 7M, etc. Be

  The grip strength detection mechanism 1 has a peripheral wall made of a transparent or translucent resin material so that the light emission of the light emitting diodes 8A to 8M can be visually recognized from the outside through the display unit 7 attached so as to cover the wiring substrate 23. The end portion 3 is formed by fitting a cylindrical outer cap 35 having a high height to the outside of the top cap 16 so as to cover the display unit 7.

  Thus, both ends of the grip portion 12 made of a cylindrical flexible member are sealed by the end cap 13 and the top cap 16 as sealing members, and a deformable sealed space 18 surrounded by the grip portion 12 The pressure sensor 28 held by the sealing member detects and displays a change in pressure of the sealed space 18.

  Further, each end of the grip portion 12 is pressed against the flange 11A of the battery case 11 and sealed by the cylindrical battery case 11 having the flanges 11A and 11A at both ends, and inside the battery case 11 By holding the dry cell 24, it can be configured to be portable and usable, and the whole can be made portable and small and lightweight. Moreover, by making the whole into a cylindrical shape, the shape excellent in design can be obtained.

  FIG. 4 is a block diagram showing the configuration of the grip strength detection mechanism 1. In the grip strength detection mechanism 1, the supply of power is started by the operation of the power switch by the switch unit 5, each unit starts operation, and the entire operation is controlled by the control unit 31 which is a computer provided on the wiring board 23. In addition to detecting and measuring the grip strength, the display of the display unit 7 is switched to cause the user to execute training based on the detection and measurement results, and further, the signal output unit 32 is driven to generate a signal sound.

  FIG. 5 is a flowchart showing a processing process related to the operation of the exercise tool of the present application and the control of the control unit 31. When the control unit 31 starts operation by supplying power, in step SP2, first, detection and measurement of the maximum value by the grip strength of the dominant hand (in the present embodiment, the right hand is the dominant hand; the same shall apply hereinafter). Execute the process Here, in this detection and measurement processing, first, after making a signal sound to notify start of detection and measurement by driving the signal output unit 32, the pressure sensor 28 repeatedly detects and measures the pressure of the enclosed space 18 . According to the detection and measurement results, when an increase in pressure in the enclosed space 18 is detected, the control unit 31 determines that the user strongly grips the grip unit 2 and starts the measurement of the grip strength. After this determination, the user detects the maximum pressure just before the user grips with full force and loosens his hand, and the detected pressure is recorded as the maximum grip of the dominant hand (right hand) involved in the training.

  The following is an embodiment of the present invention.

  When the control unit 31 detects and measures the grip strength in this manner, the display unit 7 may display the detection and measurement results (step SP3). Here, as shown in FIG. 6, the control unit 31 sets, for example, in the clockwise direction from the display unit 7B with reference to the display unit 7B having a different shape among the display units 7B to 7M with a constant angular interval. Every time the measured value increases by a fixed value, the number of light emitting display units is increased. In this embodiment, when the constant value is set to 5 kg and the grip strength corresponding to the detected pressure is 0 kg or more and less than 5 kg, only the display unit 7B having a different shape is lit. In the case where the detected and measured grip strength is 5 kg or more and less than 10 kg, the display unit 7B having a different shape and the adjacent display unit 7C clockwise are turned on, and the detected grip strength is 10 kg or more and less than 15 kg , And the two display portions 7C and 7D adjacent in the clockwise direction are lighted. The above step SP3 can be omitted as appropriate.

  As a result, the grip strength detection mechanism 1 displays the grip strength measurement / detection result by stepwise display. In the display of the grip strength measurement / detection result (step SP3), a display unit capable of displaying numbers may be provided and displayed by numbers, or may be notified by voice. When the control unit 31 displays the grip in this manner, the control unit 31 may drive the signal output unit 32 to generate a signal sound to draw the user's attention.

  Subsequently, the control unit 31 waits for the elapse of a predetermined interval time (for example, one minute) while displaying the detection and measurement results of the grip strength in this manner, and then the hands used for detection and measurement of the grip strength. Training in this case (right hand in this case) is started (step SP4). Here, the control unit 31 notifies the user of the start of training by driving the signal output unit 32 to generate a signal sound. The interval time may be omitted as appropriate, and training may be started immediately without inserting the one-minute interval time. Thereafter, the pressure sensor 28 repeatedly detects and measures the grip strength. The control unit 31 sets the force of a fixed ratio of the grip force detected and measured in step SP2 (that is, the pressure less than the maximum grip force detected and measured in step SP2) as the reference grip force, and is repeatedly acquired by this reference grip force By determining the detection and measurement results, it is determined whether or not the grip strength which is continuously detected and measured is present in a predetermined range of the reference grip strength, and the determination result is displayed (step SP5).

  Here, this reference grip strength is set to, for example, approximately 30% of the grip strength detected and measured in step SP2. The control unit 31 sets a pressure within a fixed height range with respect to the reference grip force, for example, a pressure of ± 5 kg as the pressure of the upper limit value and the lower limit value, and makes the determination sequentially by the upper limit value and the lower limit value. Here, as shown in FIG. 7A, when the detection / measurement result is equal to or more than the upper limit value, the control unit 31 causes the display unit 7A at the center of the display unit 7 to display the display unit 7A in red. . On the other hand, when the detection / measurement result is less than the lower limit value, the display unit 7A at the center is displayed in yellow. When the detection / measurement result is between the upper limit value and the lower limit value, the display unit 7A at the center is displayed in blue. The color emitted by the display unit 7A is not limited to the above. For example, blue when the measurement result is equal to or higher than the upper limit, green when the measurement result is between the upper limit and lower limit, the measurement result is If it is less than the lower limit value, it may be red and can be changed appropriately.

  Thus, the control unit 31 notifies the user of the current grip strength relative to the reference grip power. The control unit 31 continues this training for a fixed time (for example, 2 minutes), and when the fixed time elapses, the signal output unit 32 is driven to generate a signal sound, and a grip release instruction to the grip is notified. (Step SP6). In addition, when the time (two minutes) of this training has elapsed, the display units 7B to 7M arranged at regular intervals are selectively displayed around the display unit 7A to notify the user. More specifically, for example, as shown by arrow A in FIG. 7A, the display portions 7B to 7M are selectively turned on or off, and the portions to be subjected to the blinking are sequentially changed clockwise. Then, the user is notified of this selective blinking by one round depending on the training time.

  In the display of pressure detection results based on such standard grip strength, in place of such three-step color-coded display by red, blue and yellow, it is executed by color-coded display by a different color It may be executed by displaying four or more levels of color coding. Alternatively, the display may be performed by selective display of the display portions 7B to 7M arranged in a circumferential shape, and a display portion of grip strength may be additionally provided to display together the detected and measured grip strengths.

  Thus, by switching the display of the display unit 7A according to the standard grip strength, the grip strength detection mechanism 1 can maintain the grip strength at the standard grip strength for a certain period of time, and can train so as to relax the finger muscles. Training has been reported to be effective in alleviating high blood pressure as described below. That is, when maintaining the reference grip strength for a certain period of time, while effectively avoiding the occurrence and deterioration of a disease associated with high blood pressure, the muscle to be gripped can be safely strained, and the muscles are rapidly It will relax and as a result, the blood vessels will dilate. Repeating this training significantly improves the elasticity of the blood vessels, and as a result, it is said that high blood pressure is improved. Thus, in this embodiment, the training utilizing the grip strength detection mechanism can prevent or further improve hypertension, and the grip strength detection mechanism can be used for the training intended for the above effect.

  When the grip is released in this way, the control unit 31 stands by for a fixed interval time (for example, one minute) (step SP7), thereby releasing the user's grip and giving a signal to take a rest time. During the one-minute interval time, for example, the display units 7B to M in the all-on state are sequentially turned off counterclockwise every predetermined time, and after one minute, all the display units 7B to M are turned off Alternatively, the user may be notified that one minute has elapsed. Further, when a certain time elapses, detection and measurement of the grip strength of the grip of the grip portion by the hand opposite to the dominant hand (in the present embodiment, the opposite hand to the left hand is the same for the left hand) are started (step SP8) The grip is detected in the same manner as described above for step SP2, and the grip corresponding to the detected pressure is displayed (step SP9).

  Step SP8 and step SP9 can be omitted as appropriate.

  Also, start training with the hand opposite to the dominant hand (step SP10), and calculate the standard grip strength from the detected and measure grip strength as in the case of the right hand, and determine the detected and measure pressure using the standard pressure And displayed (steps SP11 and SP12). In this case, as shown in FIG. 7 (B) as appropriate in comparison with FIG. 7 (A), the display on the display portions 7C to 7M is switched counterclockwise to display the passage of time, The user may be made to recognize that the training is

  In this way, when the training is ended after a predetermined time has elapsed, the number of repetitions of the training is determined, and if the number of repetitions is less than two, an interval is interposed to return to detection and measurement of the grip of the right hand and repeats a series of processing (Steps SP13 to SP14) If the processing has already been repeated twice, the entire processing is ended (step SP15).

  In addition, about operation of the exercise tool of this invention, it was possible to abbreviate | omit suitably about step SP3, step SP8, and step SP9 as mentioned above.

  In addition, it is possible to set the above standard grip strength to a value calculated from the grip power maximum value of the dominant hand initially detected and measured in step SP2, and unify it to this, thereby again detecting and measuring the grip power maximum value Can be omitted. That is, in this case, step SP8, step SP9, and step SP2, step SP8 and step SP9 of the second training after one training (steps SP1 to SP14) with the dominant hand and the opposite hand are omitted. Can.

  Next, the effect of training using the exercise equipment provided with the grip strength detection mechanism 1 of the present invention will be described.

  The contents of the training are as described in the above-described first embodiment. The operation of the exercise tool of the present invention will be briefly described again. After switching on the main body, the following operations 1 to 4 are performed.

Operation 1: After gripping the grip 12 with full force, loosen the force and release the hand. At this time, the pressure of the enclosed space 18 at 100% grip strength of the user is detected.
Operation 2: The grip portion 12 is gripped again, but this time it is gripped with about 30% of the maximum grip power of the user, and the grip strength is kept constant for two minutes while the central display 7A emits blue light. In the case where the display 7A emits light in blue while holding the grip 12, it indicates that the user holds about 30% of the grip strength in gripping the grip, and in the case of emitting yellow, the grip is weak ( It indicates that the grip is strong (grip strength exceeds around 30%) when emitting in red, that the grip strength has not reached around 30%.
Step 3: Hold for 2 minutes with a force of about 30% of the maximum grip and hold for 1 minute, then rest for 1 minute. In addition, it is important to take a break after releasing the grip for one minute.
Step 4: Steps 1 to 4 are divided into one operation, which is repeated twice with the left and right hands a total of four times (one set).

  When the exercise tool of the present invention is used, use at a position lower than the heart is effective. For example, the exercise tool of the present invention is placed on the thigh and grips the grip portion 12 while sitting on a chair And more effective.

  In order to confirm the effect brought about by the above-mentioned training, actually 10 subjects use the exercise equipment of the present invention to perform the above-mentioned series of exercises (operations 1 to 4) twice with the left and right hands. Repeating (1 set) was performed for 4 weeks at a pace of 5 days a week, and under the supervision of the exercise physiology laboratory of Nippon Physical Education University, the numerical value of the highest blood pressure of each subject was measured.

  Table 1 lists the sex and age of each subject, and also the numerical values of the measurement results of systolic blood pressure in the first week and the fourth week of each subject. In the examination, as described above, the exercise tool of the present invention is carried out once a day (8 minutes + 3 minutes), one set for 4 weeks, as described above, without changing the lifestyle habits so far. Then, at the first week and the fourth week, they are measured at the daily exercise physiology laboratory. Once a day (8 minutes + 3 minutes) and 1 set, as mentioned above, the exercise equipment of the present invention with a grip of 30% "2 minutes hold for 1 minute rest" twice a total of 4 times with the left and right palms repeat.

  As is clear from Table 1, all four of the 10 patients showed a decrease in systolic blood pressure in 4 weeks. In addition, it was also confirmed that there is a drop in systolic blood pressure among those who take antihypertensive drugs.

  The reason why the systolic blood pressure has been lowered is still under study, but by holding the exercise tool of the present invention for 2 minutes with a grip strength of about 30%, the muscle of the arm compresses the blood vessels and blood circulation (blood flow) Although it drops a little, when you rest for the next minute, as soon as the muscle relaxes, blood circulation in the blood vessel is activated to stimulate the cells inside the blood vessel, and this stimulation stimulates NO (from the inner wall of the blood vessel) It is reasonably presumed that the cause is the active secretion of nitric oxide).

  That is, NO (nitric oxide) is made of a thin vascular endothelial cell on the inner wall of the blood vessel, and serves to spread the blood vessel, improve circulation, keep the blood vessel soft and stabilize the blood pressure.

  In addition, NO (nitric oxide) decreases in secretion when the function of the thin vascular endothelial cells diminishes due to aging, disturbance of lifestyle, stress or the like, and as a result, blood pressure tends to rise. Therefore, it is found that by holding the rest of the exercise apparatus of the present invention alternately with both hands with a grip of about 30%, NO is secreted from the blood vessels of both arms and circulated around the whole blood vessels to lower blood pressure. It was obtained.

  Also, as seen in Table 1, the effect was also seen in those taking antihypertensive drugs. It seems that NO works to keep the blood vessels soft and to break down the plaque that may clog the blood vessels.

  The specific configuration suitable for the implementation of the present invention has been described above in detail, but the present invention can be variously modified in the configuration of the above-described embodiment without departing from the spirit of the present invention. It can be combined.

  That is, although the above embodiment describes the case where approximately 30% of the detected and measured maximum grip is set as the reference grip, the present invention is not limited to this, and in the case of the reference grip, gripping by continuation of a fixed time It can be changed variously as long as it does not burden the human body. In addition, the upper limit value and the lower limit value related to the determination can be variously set in the same manner.

  In the above embodiment, the case of setting and recording the standard grip by detecting and measuring the grip every training has been described, but the present invention is not limited to this, and in the case where it is practically sufficient, The setting of the standard grip may be omitted.

  In the above-mentioned embodiment, although the case where training concerning the handgrip of the right hand and training concerning the handgrip of the left hand were performed by processing of a continuous control part was described, the present invention is not limited to this and is carried out individually. You may do so.

  Although the above embodiment has described the case where training related to the prevention of hypertension is performed by detecting and measuring the grip strength, the present invention is not limited to this, and the mode of detection and measurement of grip strength and such training It may be set to be executed by switching the above, and it can be applied to the case where only grip strength is simply detected and measured.
