  When the user 1 finishes exercising, the heart sound sensor 2 is attached to the chest near the position of the heart and the heart sound S is recorded. For example, a microphone is used as the heart sound sensor.

  The heart sound S can be picked up even while exercising, but it is not desirable because of noise.

  The measurement data of the heart contraction or expansion of the measurement data of the present invention is most preferably immediately after exercise.

  The heart sound sensor 2 records the heart sound S, and the analog signal A is sent to the AD conversion unit 3 through the cable 2a.

  The AD conversion unit 3 includes a crank circuit 3a, an AD converter 3b, and a memory circuit 3c so that the level of the analog signal A does not change.

  The conversion of the digital signal D from the analog signal A of the sound pressure signal level is performed by first amplifying the weak current of the sound pressure signal level and adjusting the sound pressure of 64 gradations in the range of 4A (ampere) to 20A by the 6-bit AD converter 3b. A sound pressure signal level that can be confirmed by level is judged as “1” of 64 gradations, and “0” is assigned when there is no sound pressure level, so that an analog signal of one cycle is “1” or “1”. A “0” matrix table (FIG. 6) is created.

  The matrix table (FIG. 6) is stored in the memory circuit 3c, and at the time of transmission, digital signals “0” and “1” are transmitted by sequentially scanning the matrix table along the horizontal axis or the vertical axis.

  The 6-bit AD converter 3 may use, for example, 12 bits, 24 bits, 48 bits, etc., and 64 gradations may be 128 gradations, 256 gradations, and 512 gradations.

As shown in FIG. 2, the heart sound 2 is repeated with contraction Y and expansion Z as one cycle (Y + Z).
The memory circuit 3c stores the 64-gradation sound pressure signal converted into the digital signal D by the AD conversion unit 3 in units of one cycle, is connected to the Internet 5 from the user terminal 4, and is managed by the management server 6 as measurement data. Sent to.

  The AD conversion unit 3 and the user terminal 4 are connected by a cable 3d.

  For example, the AD conversion unit 3 can be incorporated in the user terminal 4, and in that case, the cable 3d is unnecessary.

Further, as shown in FIG. 3, the AD conversion unit 3 may be a separate type fixed to a part of the body like a fixed band 16, or may be incorporated in a mobile phone or a PC of the user terminal 4.
The management server 6 receives the measurement data transmitted from the user terminal 4 by the mail receiving means 7.

  The management server 6 includes a database 10 and is connected to the user terminal 4 via the Internet 5 so as to be able to send and receive e-mails. The user information data 12 and measurement information data 11 for each user are included in the database 10 and an e-mail address. A mail address confirming means 9 for confirming, and a mail transmitting means 8 for transmitting an e-mail created by the measurement data analyzing means 13 and the mail creating means 14 to the user terminal 4 at the delivery address of the user.

  The digital signal D received by the digital signals “0” and “1” is reassembled into a matrix table (FIG. 6) using the measurement information data 11 included in the database 10 of the management server 6.

  In the user information data 12 of the database 10 included in the management server 6, the measurement data of each person measured and accumulated in the past is recorded.

  In the user information data 12, personal data such as the age, sex, height, weight, medical history, lifestyle, etc. of each person is recorded.

  The measurement information data 11 is input with scientifically verified scientific data.

  Based on the user information data 12 and the measurement information data 11, the measurement data transmitted from the user terminal 4 via the Internet 5 is analyzed by the measurement data analysis means 13 to evaluate the exercise load intensity.

  When the measurement data analysis means 13 performs the exercise load intensity evaluation, the exercise load intensity evaluation is created by the mail creating means 14, the user is confirmed by the mail address confirmation means 9, and the Internet 5 is transmitted by the mail sending means 13. Is transmitted to the user terminal 4 via.

  According to FIG. 2, the amplitude X indicates the contraction force of the heart, Y indicates the contraction time of the heart, and Z indicates the expansion time of the heart.

  The heart sound S is composed of two of the amplitude X when S1 is contracted and when S2 is expanded.

  Heart sound S is repeated with contraction Y and expansion Z as one cycle (Y + Z).

  A sound pressure is generated in the heart sound at the start of contraction, which is called heart sound S1 and can be grasped by an analog waveform.

  Further, sound pressure is generated although it is weak at the end of contraction. This is also called heart sound S2 and can be grasped by an analog waveform.

  When the exercise load is strong, the heart contracts strongly and supplies blood to the body. The sound pressure of the heart sound S1 generated at this time is high, and the analog waveform is also large.

  Conversely, when the exercise load is weak, the heart contracts weakly and discharges blood to the body. In this case, the sound pressure of the heart sound S1 is low and the analog waveform is also small.

  Usually, the expansion time becomes shorter if the contraction force X is strong, and becomes longer if the contraction force X is weak.

  When the contraction force X is strong and the ratio of the expansion time to one cycle is extremely small, it is evaluated that the exercise load intensity is too strong.

  Conversely, when the contraction force X is weak and the expansion time for one cycle is long, it is evaluated that the exercise load intensity is weak.

  If it is evaluated that the exercise load intensity is too strong, the body is adversely affected unless the exercise load is weakened. If the exercise load intensity is evaluated to be weak, the exercise load is not increased unless the exercise load is increased.

From the relationship between the input exercise load and the corresponding amplitude of S1 and the ratio of the extension time, the intensity range where S1 starts to increase rapidly and the ratio of the extension time is constant becomes a safe and effective exercise range.

  A scientific exercise load intensity evaluation can be obtained by measuring the strength of one cycle of amplitude X and contraction Y and expansion Z, the magnitude of the waveform, and the time.

  It can be said that the longer the time of one cycle (Y + Z), the less the burden on the heart.

  In one cycle (Y + Z), the analog waveforms of S1 and S2 of the amplitude and sound pressure level of the heart sounds of the contraction Y and the expansion Z of the heart can be read.

  The analog waveform of S1 and S2 of the amplitude and the sound pressure level of one cycle (Y + Z) is repeated.

  FIG. 3 shows a mobile phone of the user terminal 4, in which the heart sound S is recorded by the heart sound sensor 2 in which the exercise load intensity of the user is attached to the chest near the heart, and the analog signal is converted into a digital signal. The conversion unit 3 is fixed to the user's arm with the fixed band 16, connected to the mobile phone with the case 3 d from the AD conversion unit 3, and transmitted to the management server 6 using e-mail.

  The measurement data transmitted from the user terminal 4 is received by the mail receiving means 7 of the management server 6. The management server 6 includes a database 10 and is connected to the user terminal 4 via the Internet 5 so as to be able to send and receive e-mails. Each user information data 12 and measurement information data 11 is included in a database, and an e-mail created by the measurement data analyzing means 13 and the mail creating means 14 is added to the user's distribution address. For the mail transmitted by the mail transmitting means 8 to be transmitted to the user terminal 4, the exercise load intensity evaluation is displayed on the display unit 16 of the mobile phone of the user terminal 4. FIG. 4, FIG. 5 and FIG. This is a screen example.
