[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a health condition for grasping the correlation between the amount of physical activity and the degree of physical fatigue when an elderly person exercises to judge whether or not the exercise is appropriate for that person. Regarding management device.

[0002]

BACKGROUND OF THE INVENTION In recent years, sudden death during sports has become a problem as the number of elderly sports population increases. It is thought that this is because the function of the body cannot keep up with the amount of exercise when the elderly person, who is usually not very active, suddenly performs intense exercise, and the body is overloaded. In order to prevent this, it is necessary to understand the relationship between the amount of exercise and the degree of physical fatigue individually and avoid exercise that causes excessive fatigue.

On the other hand, recently, with the development of IC and sensor technology, information such as body temperature, heart rate, respiration rate, blood pressure, and perspiration can be easily measured with a device as small as a wristwatch. Therefore, with these devices, the degree of physical fatigue during exercise can be predicted.

However, with such a device alone, it is only possible to make an expression such as "how many heartbeats are there in one hour of jogging", and the amount of exercise cannot be objectively grasped.
Especially in the case of exercise for the elderly, there is a large difference in physical strength between individuals, so there is often a large difference in the amount of exercise even for the same one-hour jogging, and it is not possible to grasp the exact amount of exercise generally based on the amount of exercise time and the number of steps taken. . In addition, it is not only the elderly who need to accurately understand the relationship between the physical fatigue level and the amount of exercise, but also the athlete.

[0005]

[Technical Items Attempted to Develop] The present invention has been made in view of such a background, and the correlation between the amount of physical activity and physical fatigue required for health management or sports management can be easily and in real time. This is an attempt to develop a health management tool for exercise that can be grasped as described above.

[0006]

[Constitution of the invention]

[Means for Achieving the Object] That is, the first invention according to the present application is to provide a health management apparatus for exercise, which includes an exercise tool including an impact amount sensor during exercise and a signal transmitting unit, and a physical fatigue sensor during exercise. And a device main body including a signal receiving unit, and an arithmetic processor for performing arithmetic processing on information obtained from an impact amount sensor and a physical fatigue sensor in any one of the exercise equipment and the device main body. And a notification means for outputting the result of the arithmetic processing, and the impact amount sensor is characterized in that the conductive gel is a pressure-sensitive conductive element.

In addition to the above-mentioned requirements, the second aspect of the present invention according to the present invention is characterized in that the exercise equipment is athletic shoes. The above objects are achieved by these inventions.

[0008]

In the present invention, since the correlation between the amount of impact during exercise and the degree of physical fatigue can be announced by the notifying means, it is possible to check whether the exercise exerts an excessive burden on the body during exercise. You can check in real time. In addition, the athlete can think of pace allocation while looking at the display and can practice efficiently without fatigue.

(Manufactured by Shin-Etsu Chemical Co., Ltd.), F250-121 (manufactured by Nippon Unica Co., Ltd.) and the like.

In addition to the components A, B and catalysts described above, pigments, curing retardants, flame retardants, conductive fillers, etc. may be added within a range that does not impair the properties of the silicone gel, and further prevent In order to improve vibration and buffering properties, a silicone gel mixed with a filler of minute hollow spheres may be used. Such filler material may be Philite (registered trademark) manufactured by Nippon Philite Co., Ltd. Pancel (registered trademark) Matsumoto Microsphere (manufactured and sold by Matsumoto Yushi-Seiyaku Co., Ltd.) can be exemplified.

Further, if soluble granules such as salt are mixed in the silicone gel stock solution and poured into a mold, and the soluble granules are melted out in water after curing by heating, a porous silicone having a greater buffering effect is obtained. A gel can be obtained.

The conductive silicone gel 10 is a silicone gel to which a conductive filler is added in order to impart conductivity. As the conductive filler, carbon black, carbon fiber, graphite, metal powder, metal oxides, metal flakes, metal fibers and the like, other than the conductive substance itself, insulating organic, inorganic fine particles nickel, cobalt, gold, There is a plated or coated conductive material such as silver.

In general, these have an arbitrary shape such as a spherical shape, a flaky shape, or a fibrous shape. In the present invention, any of these conductive fillers can be used, but the conductive silicone gel is finished. When the amount of compressive displacement is plotted on the horizontal axis and the electrical conductivity is plotted on the vertical axis, the conductivity curve has a downward sloping right, and if one or more fibrous fillers are applied, the pressing force It is possible to obtain a relatively easy-to-use conductive silicone gel in which the conductive state is improved in proportion to.

The conductive silicone gel 10 can also be made porous by the above-mentioned method, but in this case, salt is not used as much as possible to prevent the oxidation of the filler, and sucrose, glucose and the like are not used. It is desirable to apply non-electrolyte-based soluble granules. When a spherical or scaly conductive filler whose conductivity curve normally rises to the right is applied to the porous conductive silicone gel sheet, the conductivity curve falls to a relatively steep downward slope. Therefore, it becomes an easy-to-use filler. When a hollow sphere-plating type conductive filler is applied to a porous conductive silicone gel sheet, the conductivity curve also decreases to the right, but such conductive filler has a specific gravity of the silicone gel stock solution. Since the difference is eliminated, there is an advantage that the dispersibility of the filler is good.

By the way, since the conductive silicone gel has not only the function as a sensor but also the cushioning and vibration-proofing function of the silicone gel itself, if it is provided on the sole of the shoe, the impact on landing is alleviated. If you apply it to the grip part of the boat oar etc., as will be described later,
Not only cushioning, but also contributes to good grip and stress relief. Therefore, in this embodiment, it is not always necessary to separately provide the silicone gel 9, and a structure in which the conductive silicone gel 10 is incorporated into the silicone gel 9 may be adopted.

For example, the amount of impact per unit time is integrated to index the momentum, and the change over time of this index value is shown in FIG. 3 (a). The bar graph 20 may be displayed on the display unit 17. Incidentally, such a bar graph 20 serves as a good pacemaker when continuing exercise while maintaining the same amount of exercise, and can be used for practicing a marathon or the like.

Furthermore, as shown in FIG. 3B, the relationship between the index value of the amount of exercise and the heart rate representing the degree of physical fatigue is displayed on the display unit 17 as a line graph 21 plotted at regular intervals as shown in FIG. 3B. You can also By the way, looking at the line graph 21 as described above, for example, even if there is no change in the amount of exercise, it can be determined that the body is being overloaded when the heart rate is abnormally high, and it is possible to determine whether the exercise is interrupted or stopped. Actions such as mitigation can be taken immediately.

In addition, the arithmetic processing unit 19 counts the number of impacts and multiplies the number of steps by a stride input in advance to calculate the total running distance, or calculates the average speed from the required time, The data may be displayed on the display unit 17. Furthermore, in the arithmetic processing unit 19,

Can be used as the stimulus, and any means can be used as long as it can be recognized visually or aurally by an exerciser or its observer. Further, in the case of using voice, it is preferable that the exerciser wears an earphone, a receiver and the like because it is mobile.
