Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supports walking, jogging, and other rhythmic exercises as exercises.
The present invention relates to an improvement in an exercise support device for enhancing body fat burning efficiency and exercising healthily, happily, and safely.

[0002]

2. Description of the Related Art Many people, regardless of whether they are sportsmen, maintain or improve their health, such as walking, jogging, treadmill exercise, steppers, skywalkers, etc. Exercise is taking place. If you are a professional sportsman,
In sports gyms, etc., there are specialists (instructors) who have acquired health management skills. However, in the case where amateurs, children, and ordinary people who cannot be said to be sportsmen personally exercise around the home, self-management is required. There is no other way than to do it.
And often, accidents are reported that can only be attributed to sudden or extreme exercise, and the need to manage the level of exercise for health promotion is highlighted.

[0003] However, the health condition of a person depends on the physical condition of the day,
In addition to being affected by the mental state, it is also affected by outdoor environmental changes such as temperature and humidity, the presence of sunshine and wind, so it is important to determine how much exercise is useful for promoting health and how dangerous it is It is very difficult for amateurs. As an example of the exercise support device invented from such a viewpoint, FIGS. 11 and 12 show a device as a running pacemaker disclosed in Japanese Patent Application Laid-Open No. 61-953. This allows the user to easily take a fixed pace that is set in advance, and also measures the pulse and automatically lowers or lowers the pace if this exceeds a predetermined upper limit or falls below a predetermined lower limit. Raised, so that you can always exercise safely.

FIG. 11 is a block diagram of the electric circuit, and FIG.
2 is a diagram showing an appearance and a use state. In the figure,
1 is a main body of a running pacemaker, 2 is a pace signal generating means (variable frequency oscillation circuit) for generating a pace signal at a set speed, and 3 is a pace instructing means for notifying the pace signal as a sound from a speaker 24 or by displaying it. is there. Reference numeral 4 denotes a detector 6 attached to the body as pulse detecting means and an amplifier 7 for amplifying the signal. The display means 5 comprises a counting means 14 for counting either the pulse rate detected by the pulse detecting means 4 or the pace signal, and a display means 15 for displaying the counted value.

Reference numeral 17 denotes a pulse rate setting means, and reference numeral 18 denotes a pulse comparison means (digital comparator) which compares the set reference pulse rate with the detected pulse rate and outputs an output signal corresponding to a deviation between the two. . The pulse rate setting means 17 includes a pulse lower limit value setting dial 21 and a pulse upper limit value setting dial 22.

Next, the operation and usage will be described. Power on
OFF and other explanations that seem to be natural or too detailed in terms of operation principle are omitted. Before starting the running, the pacemaker 1 was attached to the wrist as shown in FIG.
Put 0 on your finger. With this, the pulse rate is measured and displayed.
The user sees this and checks and confirms his / her health condition. Next, the pulse lower limit value setting dial 21 and the pulse upper limit value setting dial 22 are operated to set the upper and lower limits of the allowable pulse rate based on the physical condition of the person. Next, when a desired pace is set in the pace signal generating means 2, the speaker 24
, So that the pace sound like pi, pi…
Just run along with this.

If the pulse rate exceeds the upper limit while the vehicle is running, the output of the pulse comparing means 18 causes the output pace of the pace signal generating means 2 to decrease. When the pulse rate falls below the lower limit during running, the output pace of the pace signal generating means 2 is increased by the output of the pulse comparing means 18 and the output pace is controlled so as to approach the set pulse rate. The momentum is controlled.

As described above, the running pacemaker is useful for maintaining a constant pace of exercise in a steady state. However, as is well known, it is important to perform a preparatory exercise before and after the start of the exercise and to slowly start and end the exercise. Accidents such as cardiac paralysis in exercise occur when sudden changes in physical load occur immediately after the start of exercise,
Alternatively, although there are many cases that occur when the load suddenly changes at the end of the exercise, there is a fundamental problem that the above-described conventional device configuration cannot cope with the above-mentioned transient.

[0009]

Since the conventional exercise support device is configured as described above, there are the following problems. 1) Since only the pulse rate of the user is detected, the control is delayed and an overload pace is easily generated, which is not preferable for health. In addition, the pulse rate is not stabilized at a steady value for some people even if they exercise at the indicated pace. 2) Since the output is a dry electronic sound, it lacks fun.

3) At the beginning of exercise and at the end of exercise transition at the end of exercise, it is not possible to instruct a pace change necessary for health corresponding to warming up and cooling down such that the exercise amount is gradually increased and gradually decreased. . 4) The use effect is low only after the movement enters the steady state, and the use efficiency is low.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a fun exercise and exercise device that can control the pulse rate extremely stably and is fun to use. It is another object of the present invention to provide an exercise support device capable of instructing a change in pace necessary for health corresponding to warm-up and cool-down. In addition, including the momentum of the momentum from before the start of the exercise until after,
An object of the present invention is to provide an exercise support device that can be used effectively and has high use efficiency.

S and the above-mentioned music data are stored. 100
Is a main body of the exercise support device. Body part 100
Is mounted on the body or clothing of the user, and is connected to the main body 100 by a lead wire or wireless transmission means (not shown). Although a power source is necessary, it is not shown. The use state explanatory diagram of FIG. 2 will be described. FIG. 2 shows a jogging state outdoors as an example of exercise, and a main body 100 of the exercise support device.
The exercise step sensor 31 is attached to the waist band, and the sounder (earphone) 43 and the pulse sensor 32 are attached to the ear.

Next, the operation will be described with reference to the functional circuit diagram for explaining the operation in FIG. 3 are a plurality of music data stored in the memory 44.
Reference numeral 52 denotes music data selection means for selecting a specific one from music data, and 53 denotes selected music data.
First, for example, the following items are input from the use condition input means 35 (using the input device 33) or selected from among items registered in advance. a) The intensity of the exercise to be started here, for example, the degree of exercise such as "walking", "jogging", "skywalker" and other types, fast, slow, normal. b) The expected duration of this exercise, for example, 1 hour or 3 hours. c) The title or type of music to be used. d) Your pulse rate at rest.

The target pulse rate time function generating means 36a creates a time change pattern of the pulse rate from the start time to the end time of the exercise of the target pulse rate of the user based on the above input items, After the start signal input by the user,
Output HBd (t) that varies with elapsed time (FIG. 4a)
Occurs. When the start button (not shown) is turned on,
First, since the selected music is reproduced at the original reproduction tempo (Tx) of the music, the user can adjust to the music (if the selection of music is not appropriate and it is difficult to exercise in accordance with the music). Start exercising at your own pace). FIG. 4b shows the change in tempo of the music played.

The exercise sensor 31 detects the exercise tempo of the user as a pulse signal, and the exercise tempo calculation circuit 31a calculates the exercise tempo Wh (t) based on the pulse signal (FIG. 4).
c). Next, the difference between the pulse rate HB (t) (FIG. 4d) obtained by the pulse sensor 32 and the pulse rate calculation circuit 32a and the target pulse rate HBd (t) is HBd (t) −HB (t) = ΔH ( t) (1) (FIG. 4e) is calculated by the pulse comparison circuit 36b.

Next, music tempo correction amount calculating means 38a
Accordingly, the correction value required to correct the exercise tempo of the user in a direction in which the difference ΔH (t) in the pulse rate becomes zero is equal to ΔH (t) and a predetermined constant (A) in the original tempo Tx of the music. , And the correction value is added to a predetermined multiple D · Wh (t) of the user's exercise tempo to calculate the corrected music tempo Wm (t). (FIG. 4f) Wm (t) = D · Wh (t) + A · ΔH (t) · Tx = D · Wh (t) + A · [HBd (t) −HB (t)] · Tx (2) And 0.5 ≦ D ≦ 2, and can be set arbitrarily. For example, if D is 2, the tempo is twice the tempo of the exercise, but this may be easier to match depending on the type of music (this does not necessarily mean that the tempo is doubled). The music data 52 selected by the output tempo Wm (t) determined in this way is corrected by the music data correction circuit 38b, and the music is reproduced at the corrected tempo. At this time, if the tempo suddenly changes greatly in the middle of the song, the user feels uncomfortable, so that the correction is gradually performed over time so that the tempo changes slowly. That is,
It is preferable that the tempo be changed at a change pace of about 20% or less per minute at the earliest.

A can be set. In equation (2),
If A is set to zero, the music tempo can be matched to the current user's exercise tempo. This is called user tempo control, and the tune is adapted to the tempo of the user's exercise, so that the user can exercise easily (whether or not it becomes a discipline). If you're tired but don't want to stop exercising, you can exercise at your own pace and have fun with the music. When A is not zero, the strength of inducing the movement increases according to the magnitude of A. Such a state is called guided rhythm control. Control is performed so that the user's pulse rate follows the target pulse rate, so that training can be performed according to the degree of exercise initially set.

FIG. 5 shows correction characteristics of the correction by the correction amount calculation circuit 38a for the music data to facilitate understanding. The horizontal axis in the figure is the target pulse rate HBd (t) and the pulse rate HB
(T) is a difference ΔH, where zero indicates a state in which the two coincide with each other, plus indicates a state of HBd (t)> HB (t), and minus indicates a state of HBd (t) <HB (t). I have.
The vertical axis indicates the tempo Wm (t) of the output music, ΔH
Is zero, then Wm (t) = D · Wh (t). Here, D is the same as D described above, but the characteristic line shown in FIG. 5 is a line when D = 1. The exercise tempo Wh (t) is, of course, a variable. If the exercise tempo Wh (t) changes, the characteristic line in FIG. 5 moves up and down. Tx is the original tempo of the selected music and is a constant. And the music used is
Since the user has selected it because he / she thinks it is suitable for the exercise to be performed, the original tempo Tx and the exercise tempo W
There is no significant difference in h (t).

The slope A in the graph of FIG. 5 depends on, for example, the intensity of the exercise input first. It goes without saying that even if the music is reproduced at different tempos, the pitch is not changed. Further, the lines B · Tx and C · Tx in the figure indicate the limitation on the range of change of the output tempo Wm (t) described in the second embodiment. The display unit 34 displays each input information for confirmation, displays the remaining time of the exercise, the current pulse rate, the target pulse rate and its difference, the title of the music, and the like.

Embodiment 2 FIG. Equation (2) shown in Embodiment 1 Wm (t) = Wh (t) + AＡΔH (t) ・ Tx = Wh (t) + A ・ [HBd (t) -HB (t)] ・ Tx If the output tempo Wm (t) is too far from the original tempo Tx of the music, the user will feel uncomfortable. Therefore, as shown in FIG. 6, a tempo correction amount limiting circuit 45 is provided so that Tx and W
The ratio with m (t) is monitored, and if this ratio exceeds a predetermined range, further changes in Wm (t) are suppressed. That is,
B · Tx> Wm (t)> C, where B and C are predetermined constants
-Add a limit of Tx.

This restriction level is shown in FIG. For example, the values of B and C are often, for example, about 2 for B and about 0.5 for C. However, since the values vary depending on the type of music selected and the sensibility of the listener, the number of B and C is determined in particular. Not something. Tempo correction limiting circuit 45 is used in the first embodiment.
It goes without saying that the present invention can be used not only in the above case but also in other forms described below.

Embodiment 3 FIG. 7 shows a control circuit of the exercise support device according to the third embodiment. In the case of Embodiment 1,
The tempo of the music changes during exercise, but in some cases, it may be more comfortable to listen to the music at the original tempo Tx (very close tempo). Therefore,
Wm ′ (t) = E · (Wh (t) + F · ΔH (t)) (3) is obtained by the tempo correction amount calculation circuit 38C shown in FIG. Here, E and F are constants. E may be 1, but the music may be reproduced at half, twice, or three times the tempo, for example, 1/2, 2, or 3. In this case, half, 2
It does not mean exercising at twice or three times the pace, but means that one movement of the exercise is matched to 拍, 2 and 3 beats of music. Next, the weighting arithmetic circuit 46 sets the number α of 0 to 1 between the original tempo Tx and the corrected tempo Wm ′ (t) as a weighting coefficient and Wm ″.
(T) is set as the output tempo again, and music is reproduced based on Wm ″ (t) calculated by calculating Wm ″ (t) = α · Tx + (1−α) Wm ′ (t) (4) May be. Here, if α is set to 0, the correction (F · ΔH (t)) for bringing the pulse closer to the target is calculated using the exercise tempo W
The reproduction is performed by the correction just added to h (t), and α is set to 1
Then, the music is reproduced at the original tempo Tx.

Α may be input from the input means 33 and set to a constant value, or may be a predetermined pattern, for example, α = 1 during warm-up immediately after start.
And, over time, a smaller value if desired,
At the time of cool-down, control may be automatically performed to gradually return to 1 from the desired value. This is referred to as weight coefficient program control. It should be noted that W in the above equation (3)
Wm obtained in Embodiment 1 instead of m ′ (t)
(T) may be used.

Embodiment 4 FIG. In the third embodiment, the user can change the tempo of the output music by changing the setting of the weight coefficient. However, for example, there is a case where there is a demand to more actively select a reproduction tempo of music according to a preference in order to listen to music happily.
Therefore, instead of performing the correction of the expression (4) by the weight correction circuit 46 in FIG. 7, the correction by the following expression (5) may be performed. Wm ″ (t) = Wm ′ (t) + k (β · Tx−Wm ′ (t)) (5) Here, Wm ′ (t) is the same as that shown in equation (3) of the third embodiment. In the same manner, E = 1. K indicates a gain and is a predetermined constant. β · Tx represents the tempo of music desired by the user. β may be input from the input means 33 and set to a constant value, similarly to α in the third embodiment, or may be a predetermined pattern, for example, β = 1 during warm-up immediately after the start, and β Control may be automatically performed to reduce the value to a small value as desired with the passage of time and gradually return to 1 from the desired value at the time of cooling down.

Embodiment 5 In the above explanation, the music data has been described without any particular restrictions on the format, so the tempo control is explained with the intent of extending or shortening the time between notes. did. However, when the music data is so-called MIDI data, the time interval between all musical notes is known in advance, so that the interval between musical notes is controlled for each musical note based on the number of beats (phase control). You may do so. If the user feels strange when the time interval changes for each musical score, the phase may be controlled for each bar.

FIG. 8 is a functional circuit diagram for explaining the exercise assisting device based on the phase control. In the figure, music data 53 is M
It is configured in the IDI format, and the time interval for each musical score is output as phase data. Reference numeral 31b denotes a phase detection circuit that detects the phase of the motion (or time for each step) based on the output of the motion sensor 31. The motion sensor 31 and the phase detection circuit 31b constitute a motion phase detection means. Reference numeral 38X denotes a phase correction amount calculation circuit that corrects the phase of each music score of the music data 53. Reference numeral 38Y is a music data correction circuit for correcting the original music data based on the phase corrected by the phase correction amount calculation circuit 38X. In the case of FIG. 8, the phase correction amount calculation circuit 38X calculates Wm (t) = D · Wh (t) + A · ΔH (t) · Tx = D calculated by the tempo correction amount calculation circuit 38a of FIG. 3 of the first embodiment. Wh (t) + A. [HBd (t) -HB (t)]. Tx: Performs the same calculation as (2), and based on this tempo, the phase control angle β
Is calculated as β = Y · (Wm (t) / Tx) using Y as a coefficient, and corrected by adding to the phase of MIDI data.

As another method, phase difference information between the timing of the exercise tempo signal detected by the exercise sensor 31 and the timing of the tempo of the music being output is obtained, and the music is shifted in a direction to reduce / increase this phase difference. May be advanced / delayed. That is, the movement phase detecting means detects a time difference between the output timing of the musical score of the music data and the movement timing of the user's movement as the movement phase with respect to the music data tempo. In the description of each embodiment, what is called a circuit is the same as the means of the present invention. The music data may be stored in a storage medium such as a CD or an MD, or may be transmitted every time by telephone or broadcast.

The exercise support apparatus according to each of the embodiments described above is housed in, for example, a box of a portable telephone so that music data taken in by a portable telephone (such as the Internet) can be stored in a memory. In other words, exercise using the latest popular music data becomes possible, and it is possible to handle the music more happily. In addition, if a part of the electronic circuit is shared with the electronic circuit for a mobile phone, the configuration can be reduced.

[0041]

As described above, the exercise support apparatus according to the present invention is based on the difference between the target pulse rate and the current pulse rate, and outputs the music tempo based on the current exercise tempo of the user. Is corrected, so that an effect that an effective exercise can be performed while listening to music happily is obtained.

Also, the music tempo is determined by weighting and adding the tempo controlled based on the difference between the target pulse rate and the current pulse rate and the original tempo of the music. Can be controlled.

Also, since the weighting coefficient can be arbitrarily set by the user, control can be performed according to the physical condition and mood of the user on the day.

Further, since the weighting coefficient can be program-controlled by a predetermined pattern, control suitable for warming up and cooling down can be performed.

In addition, since there is provided a tempo correction amount limiting circuit for limiting the corrected music tempo within a predetermined multiple of the original music tempo, it is possible to exercise happily without discomfort.

In addition, music can be reproduced and enjoyed with a setting that emphasizes the original tempo of music.

In the case where the music data is MIDI format data, since the phase correction amount calculating means for correcting the phase of each musical score is provided, the music can be controlled according to the timing at which the user moves his / her body. , Less discomfort,
Music control becomes possible.

Also, since it is incorporated in the case of the portable telephone, it is convenient to carry around and exercise, and it has an effect that the latest music data can be easily taken in.
