Description

The present invention relates to a training support method and a training support system.

Conventionally, smart watches with GPS that measure and display various data (distance, speed, pace, pitch, heart rate, output, vertical movement, etc.) during exercise such as running, bicycle (road bike), swimming, etc. are widely known. Has been done. Many of such smart watches have a function of comparing exercise results with preset general threshold values (indexes) and presenting them to the user. For example, Patent Document 1 includes a sensing unit configured to be attached to a user's shoes, and the sensing unit includes a gyro sensor and is configured to monitor the movement of the foot during the user's exercise. Represents a processing means for obtaining the user's first ability characteristic including the foot landing location of the user's foot when landing on the ground surface based on the sensor 1 and the output from the first sensor, and the ability characteristic. A system with a transmission means for transmitting a data package to a remote receiver is described.

In addition, the exercise ability of the user is measured by measuring the heart rate, the amount of oxygen and carbon dioxide in the exhaled breath, and the blood lactate concentration while changing the exercise intensity of the user (subject). A method is known (for example, Patent Document 2), and an attempt is made to support training for improving a user's athletic ability based on the measurement result. Here, the items indicated by athletic ability include maximum heart rate, maximum oxygen uptake (VO _2max : Maximum Volume of Oxygen Consumed Per Minute), anaerobic threshold (AT), and aerobic threshold (AT: Anaerobic Threshold). AeT: Aerobic Threshold), ventilation work threshold (VT: Ventilation Threshold), lactate work threshold (LT: Lactate Threshold), blood lactate accumulation start point (OBLA: Onset of Blood Lactate Accumulation) and the like are calculated. Among these, anaerobic work is an index that indicates athletic ability (endurance athletic ability) in so-called endurance sports such as long-distance running such as full marathon, ultramarathon, ultra trail, and long-distance compound competition such as triathlon. Threshold (AT) and lactate work threshold (LT) are widely used.

JP-A-2017-2000489 Japanese Unexamined Patent Publication No. 2016-195661

However, in conventional systems and methods that measure and utilize exercise data, the threshold value (index) to be compared with the exercise result is a general fixed value, and the exercise ability of users with different exercise abilities and experiences can be determined. It was not always well suited for the purpose of improvement. In addition, even if the user's athletic ability is individually measured as in the past and a training menu or program is created by the user based on the result, it is sufficient depending on the target athletic competition (especially endurance sports). In some cases, the training effect could not be obtained.

Therefore, the present disclosure has been made in view of such circumstances, and an object of the present disclosure is to provide a training support method and a training support system that can sufficiently contribute to the improvement of the athletic ability of users having different athletic abilities and experiences. To do.

In general, if you continue exercising for a long time, even if you maintain the same heart rate due to fatigue or lack of muscle strength, the phenomenon that the exercise speed (running speed, etc.) actually decreases can actually occur. In endurance competition, it can be said that the hypothesis that it is difficult to maintain the exercise speed in the first half is established because it stalls in the second half. However, as a result of intensive research by the present inventor in order to solve the above problems, the anaerobic work threshold (AT) and lactate work threshold (LT), which are indicators of endurance exercise ability, have been set in endurance sports. We have found that if the index is used as it is in the training of a certain exercise, the influence of the endurance competition as described above on the athlete may not be sufficiently reflected, and the present invention has been completed. That is, the present disclosure adopts the following configuration in order to solve the above-mentioned problems.

[1] An example of the training support method according to the present disclosure is
A method for assisting the training of a user who performs at least one of running exercise and bicycle exercise.
The user is provided with a first exercise motion that gives a load from the initial load in the exercise to the time when the load is gradually increased to all out, and the heart rate of the user performing the first exercise motion, and The first step to measure the amount of oxygen and carbon dioxide in the exhaled breath,
Maximum heart rate, maximal oxygen uptake (VO _2max ), anaerobic work threshold (AT), and aerobic work threshold based on the heart rate and the measured data on the amount of oxygen and carbon dioxide. The second step of calculating or estimating the athletic ability of the user including (AeT), and
The user is provided with a second exercise motion in which a heart rate corresponding to the anaerobic work threshold value (AT) is exhibited, and the second exercise motion is provided to the user after a certain period of time has passed since the first exercise motion was completed. The third step of monitoring the heart rate of the user who is performing the operation, and
A fourth step of adjusting the exercise speed so that when the user's heart rate fluctuates in the second exercise operation, the heart rate becomes a heart rate corresponding to the anaerobic work threshold value (AT).
The heart rate corresponding to the user's anaerobic threshold (AT) and the adjusted exercise speed of the user in the second exercise motion are set as indexes in the training of the exercise by the user, or , The fifth step of notifying the user as the index, and
Is configured to include.

The athletic ability may include VO ₂ SCORE (drive-in index) and various predicted times. Further, the anaerobic work threshold (AT), the aerobic work threshold (AeT), and the heart rate corresponding thereto are the oxygen amount (concentration) in the exhaled breath measured by a well-known release circuit method or the like. It can be obtained from the amount of carbon dioxide (concentration) or the relationship between the amount of exhaled breath and the pulse rate. For example, the aerobic work threshold (AeT) is set as the first-step rising start point (transformation point) of carbon dioxide in exhaled breath, and the anoxic work threshold (anoxic work threshold) is set as the second-step rising point of carbon dioxide in exhaled breath. AT), and the heart rate when those points are reached can be the heart rate corresponding to the aerobic work threshold (AeT) and the anoxic work threshold (AT). Further, the "heart rate" in the present disclosure has a certain range with respect to the central value, for example, about 0.9 to 1.1 times (center value ± 10%), or 0.95 to 1.05 times. It may have a range of degrees (median ± 10%), and in the present disclosure, the range having such a range may be expressed as being near or near (the center value of) the heart rate. ..

Here, the "all-out" in the present disclosure is a state in which the load exercise at that time cannot be continued any more (a state in which all the exercises are completed) in the first exercise motion, and the user or the administrator (observation). Indicates a state in which the person) subjectively judges, and represents a so-called "driven" state until the user is exhausted. In other words, "all-out" is a state in which an exercise load is applied to the limit points of the user's muscle endurance function and respiratory function in the exercise. In particular, the "all-out" in the present disclosure is preferably at least a state in which the user's respiratory function has reached its limit. On the other hand, in a single exercise event, for example, when the user performs a separate or similar exercise movement and then performs the first step with some muscle fatigue of the user remaining, the original respiratory function (respiratory organs) is performed. The muscle endurance function reaches the limit when the system ability) is not "all out", and as a result, it tends to be difficult for the user to continue the first exercise movement. Such implementation is not preferred in the disclosure.

In the training support method configured in this way, the first exercise motion is provided to the user, the numerical value related to the user's exercise ability is calculated once (measurement in the first stage), and then after a break for a certain period of time is inserted. The user is further provided with a second exercise motion at a heart rate exercise intensity corresponding to the anaerobic work threshold (AT). That is, an environment is created in which the endurance system ability is accurately calculated by imposing another exercise on the user who has all out in the first exercise motion. For example, a user who exercises infrequently or a user who has low endurance ability tends to be in a fatigued state for a relatively long time after the measurement by the first exercise motion. Therefore, during the second exercise motion, the anaerobic state calculated by the first exercise motion is performed. Exercise intensity at the Sexual Work Threshold (AT) can also increase heart rate. When the user's heart rate fluctuates in this way, the exercise speed is adjusted (measurement in the second stage) so that the heart rate becomes the heart rate corresponding to the anaerobic work threshold (AT), and the adjustment is performed. The later exercise rate and the heart rate corresponding to the anaerobic work threshold (AT) are set as indicators in the exercise training by the user. As a result, users are provided with training of appropriate intensity to improve their endurance ability (for example, average pace per 1km for a full marathon: this pace allows efficient running in the running economy). Can be provided.

[2] Further, in the first step, the initial load in the exercise and / or the degree of increase in the load may be adjusted according to the experience value of the exercise by the user. In general, a user who has little exercise experience or running experience tends to be in a tense state at the time of measurement in the first exercise motion, which has a great influence on the heart rate and exhalation, and when the exercise intensity increases, all out in a relatively short time. It tends to end up. Therefore, by reducing the initial load of such a user (for example, starting from walking) as compared with a user having a high experience value, it is possible to perform more accurate measurement of athletic ability.

[3] Further, in the above configuration, the user is provided with exercise in a normal pressure low oxygen concentration environment as training for the exercise, and a guideline value of the exercise speed in the training for the exercise is based on the index. The sixth step to decide and
The seventh step of continuously or intermittently and regularly or irregularly monitoring the arterial oxygen saturation (SpO ₂ ), heart rate, and exercise rate of the user who is training the exercise.
In the exercise training, the following (1) to (4);
(1) Conditions under which the arterial oxygen saturation (SpO ₂ ) is equal to or higher than a predetermined value.
(2) Conditions under which the heart rate is equal to or lower than the heart rate corresponding to the anaerobic threshold (AT).
(3) Conditions under which the heart rate is equal to or higher than the heart rate corresponding to the aerobic threshold (AeT).
(4) The heart rate becomes a predetermined value larger than the heart rate from the heart rate corresponding to the anaerobic work threshold value (AT) (for example, the upper limit in the vicinity of the heart rate corresponding to the anaerobic work threshold value (AT)). Conditions (which will be about the value),
The exercise speed and / or the eighth step of adjusting the oxygen concentration in the normal pressure low oxygen concentration environment may be further included so as to satisfy at least one of the above conditions.

Such a low oxygen concentration environment can be realized by adjusting the nitrogen concentration in the air at normal pressure, and an exercise effect equivalent to that of high altitude training in a so-called low oxygen concentration state can be obtained. In addition, by adopting training with a guideline value (for example, starting at the adjusted exercise speed) based on the appropriate index set in the 5th step, training for improving endurance system ability should be further optimized. Can be done.

[4] Further, in the sixth step, the normal pressure low oxygen concentration environment is determined according to the experience value of the predetermined exercise by the user or the experience value of training under the normal pressure low oxygen concentration environment. It is also preferable to adjust the oxygen concentration and / or the exercise speed in the above.

For example, as training in a low oxygen concentration environment, an oxygen concentration corresponding to an altitude of about 1000 m to about 5000 m can be set. Since the ability to adapt to high altitudes differs depending on the individual exercise ability of each user, users who have little experience in exercise habits and high-intensity training set the oxygen concentration in a semi-high altitude (1000 m to 1600 m) environment at the beginning of training, and exercise. The speed may be adjusted slightly higher. Normally, arterial oxygen saturation (SpO ₂ ) may be less than 90 when high-intensity training is performed in a flat environment, but if you have little experience in exercise habits or high-intensity training, you can do so. It rarely falls below 90. Therefore, when a user with little exercise experience trains in a high altitude environment, the arterial oxygen saturation (SpO ₂ ) may drop sharply, which poses a health risk and needs to be gradually adapted.

On the other hand, for users with abundant exercise experience, it is desirable to apply an oxygen concentration of about the upper limit (1600 m) of the semi-highlands at the beginning of training and adjust the exercise speed somewhat conservatively. Since the ability to adapt to high altitudes differs depending on each user, if the exercise intensity (running speed, etc.) is increased even if the exercise experience value is high, the arterial oxygen saturation (SpO ₂ ) will decrease, which is a health risk. May occur. As described above, it is desirable that the training in a low oxygen concentration environment is performed under the control of monitoring the arterial oxygen saturation (SpO ₂ ) and the heart rate.

In addition, as the main method of training in a low oxygen concentration environment, there are a method of applying a high intensity exercise load (training exceeding the usual exercise intensity) and a method of applying the usual exercise intensity. In either case, by training in an environment with low oxygen concentration, the effects of improving aerobic capacity, fat burning effect, increasing mitochondrial mass, strengthening muscle strength, improving lactic acid utilization ability, etc. can be achieved in a relatively short time. You can get it by exercising. Therefore, for users who are not so-called athletes, training in a low oxygen concentration environment is recommended as an alternative method for exercise such as normal running. In this case, as described above, improvement of the aerobic capacity can be expected by performing the heart rate between the value corresponding to the anaerobic work threshold (AT) and the aerobic work threshold (AeT).

[5] When the exercise is an exercise (triathlon or duathlon) that is continuously performed by combining both a running exercise and a bicycle exercise, the first exercise to be performed in the competition of the exercise is the earlier. After performing the step and the second step, it is preferable to carry out the third step for the exercise to be performed later in the competition of the exercise. In this way, the exercise load state in the previous competition can be reproduced once, and then an appropriate index of exercise intensity can be obtained.

[6] Further, in the above configuration, based on the exercise capacity data of the user, the following (α) to (γ);
(Α) Intense exercise (high-intensity training such as interval training and repetition training) such that the heart rate is between the maximum heart rate and the heart rate corresponding to the anaerobic threshold (AT).
(Β) Intense exercise (aerobic capacity) such that the heart rate is a value between the heart rate corresponding to the anaerobic work threshold (AT) and the heart rate corresponding to the aerobic work threshold (AeT). Training for improvement),
(Γ) The heart rate becomes a predetermined value larger than the heart rate corresponding to the anaerobic work threshold value (AT) (for example, an upper limit value near the heart rate corresponding to the anaerobic work threshold value (AT)). Exercise with such intensity (training aimed at increasing AT and exercise intensity (running speed, etc.) at the same AT),
At least one of the above, or at least a combination of two or more, may be set as the training menu of the user, or may be notified to the user as the training menu.

By doing so, for example, weekly, it is possible to propose to the user a combination of training plans in various heart rate zones according to the training principle.

[7] Further, an example of the training support system according to the present disclosure is a system for supporting the training of a user who performs at least one of running exercise and bicycle exercise.
A first exercise device that provides a first exercise motion that gives a user a load from the initial load in the exercise to the time when the load is gradually increased to all out.
A first monitoring unit that monitors the heart rate of the user who is performing the first exercise operation, and
A measuring unit that measures the amount of oxygen and carbon dioxide in the exhaled breath of the user who is performing the first exercise operation, and
Maximum heart rate, maximal oxygen uptake (VO _2max ), anaerobic work threshold (AT), and aerobic work threshold based on the heart rate and the measured data on the amount of oxygen and carbon dioxide. A calculation unit that calculates or estimates the user's athletic ability including (AeT),
A second exercise device that provides a second exercise operation in which a heart rate corresponding to the anaerobic work threshold value (AT) is expressed to the user for which a certain period of time has passed since the end of the first exercise operation. ,
A second monitoring unit that monitors the heart rate of the user performing the second exercise operation, and
An adjusting unit that adjusts the exercise speed so that when the user's heart rate fluctuates in the second exercise operation, the heart rate becomes a heart rate corresponding to the anaerobic work threshold value (AT).
The heart rate corresponding to the user's anaerobic threshold (AT) and the adjusted exercise speed of the user in the second exercise motion are set as indexes in the training of the exercise by the user, or A setting notification unit for notifying the user is provided as the index.

In addition, in this disclosure, a "part" and a "device" do not simply mean a physical means, but also include a configuration in which the functions of the "part" and the "device" are realized by software. Further, the functions of one "part" and "device" may be realized by two or more physical means or devices, or the functions of two or more "parts" and "devices" may be realized by one physical. It may be realized by physical means or equipment. Further, "part" and "device" are concepts that can be paraphrased as, for example, "means" and "system".

According to the present invention, when the user's heart rate fluctuates in the second exercise motion after the user goes all out in the first exercise motion, the heart rate corresponds to the anaerobic work threshold (AT). The exercise speed is adjusted so as to be the heart rate, and the adjusted exercise speed and the heart rate corresponding to the anaerobic work threshold (AT) are set as indexes in the exercise training by the user. As a result, it is possible to provide the user with training of appropriate intensity for enhancing the endurance system ability, and as a result, it is possible to realize the improvement of the athletic ability of the users having different athletic ability and experience.

[Operation example 1]
Next, with reference to FIG. 4, an operation example and its action and effect in the training support method using the training support system 1 will be described. FIG. 4 is a flowchart showing an example of a processing procedure in the training support method according to this operation example. The processing procedure described below is only an example, and each processing may be changed as much as possible within the scope of the technical idea of the present disclosure. In addition, the processing procedure described below can omit, replace, and add steps as appropriate according to the embodiment and each configuration example (the same applies to other operation examples).

First, the administrator of the training support system 1 activates the training support system 1 (each of the treadmill 2, the respiratory metabolism measurement device 3, and the control device 4) and various programs (measurement program, calculation program, control program, etc.). To execute. Then, the control calculation unit 41 in the respiratory metabolism measuring device 3 and the control device 4 sets an index for measuring the motor ability of the user U and running training according to the following processing procedure, and notifies the user U of the index. Further, in the present embodiment, prior to the processing in each of the following steps, the measurement parameters required in each step and the initial value sets of various calculation parameters are read from the storage unit 43 and appropriately stored in each function unit. I will do it. However, of course, the reading of such parameters may be performed at an appropriate timing as long as it is before the processing of each step.

(1st step S1)
In the first step S1, as the first step, the user U is asked to perform the first exercise motion. In this case, the user U is given a load from the initial load in running (exercise) to gradually increasing the load to all-out. At that time, the heart rate of the user U performing the first exercise motion and the amount of oxygen and carbon dioxide in the exhaled breath are measured. In the first step S1, the initial load and / or the degree of increase in the load in the first exercise operation may be adjusted according to the experience value of running by the user U. For example, by reducing the initial load of a user with a low experience value of running compared to a user having a relatively high experience value (for example, starting from walking), more accurate measurement of athletic ability can be performed. As another example, since the beginner user U tends to go all out in a short time when the running speed increases, for example, the advanced user U is accustomed to increasing the running speed while starting from a speed of about 3 km / h. Therefore, for example, a speed of about 5 km / h is started, and the degree of increase in speed is increased by 0.5 km / h in units of 30 seconds, for example.

(Second step S2)
In the second step S2, the maximum heart rate, maximal oxygen uptake (VO _2max ), anaerobic work threshold (AT), based on the measured data on the heart rate and the amount of oxygen and carbon dioxide (change). And, the exercise ability of the user including the aerobic work threshold (AeT) is calculated or estimated. As described above, the anaerobic work threshold (AT), the aerobic work threshold (AeT), and the heart rate corresponding thereto are the oxygen amounts in the exhaled breath measured by a well-known release circuit method or the like. It can be derived from the concentration), the amount of carbon dioxide (concentration), or the relationship between the expiratory volume and the pulse rate.

(Third step S3)
In the third step, the user U is asked to rest for a certain period of time (complete rest or light movement. The time is not particularly limited, but may be several minutes to several tens of minutes, and may be sufficient from the viewpoint of measurement efficiency. Good.). Then, as the second step, the user U is asked to perform the second exercise motion. In this case, the user U runs for a certain period of time at an exercise speed represented by a heart rate corresponding to the anaerobic work threshold (AT) calculated or estimated in the first exercise motion, and during that time, the user U's heart rate. Monitor the number.

(4th step S4)
In the fourth step, when the heart rate of the user U performing the second exercise movement fluctuates (in most users, the heart rate tends to be higher than the heart rate corresponding to the anaerobic threshold (AT)). ), The exercise speed of the treadmill 2 is reduced so that the heart rate returns to the heart rate corresponding to the anaerobic work threshold (AT). In other words, users with low running frequency and users with low endurance ability tend to remain in a fatigued state for a relatively long time after the measurement by the first exercise motion, so that the calculation was performed by the first exercise motion during the second exercise motion. Heart rate tends to increase even at exercise intensity at the anaerobic threshold (AT).

(Fifth step S5)
Then, in the fifth step S5, the heart rate corresponding to the anaerobic work threshold (AT) of the user U and the adjusted exercise speed in the second exercise motion of the user U are obtained in the running training by the user U. It is set as an index, the result is notified to the user, and the measurement is completed.

According to the training support method according to the present disclosure carried out in this way, the first exercise motion is provided to the user U, the numerical value related to the exercise ability of the user is once calculated (measurement in the first stage), and then a certain period of time After the break, the user is further provided with a second exercise motion at a heart rate exercise intensity corresponding to the anaerobic work threshold (AT). As a result, it is possible to create an environment in which the endurance system ability is accurately calculated by imposing another exercise on the user U who has all out in the first exercise motion. Then, in the second exercise motion, when the heart rate of the user U fluctuates, the exercise speed is adjusted so that the heart rate becomes a heart rate corresponding to the anaerobic work threshold (AT) (second exercise). (Step measurement), the adjusted exercise speed and the heart rate corresponding to the anaerobic work threshold (AT) are set as training indexes, so the user U can train the appropriate running intensity to improve endurance system ability. Can be provided to. As a result, it is possible to contribute to the improvement of the athletic ability of the users U having different athletic abilities and experiences.

[Operation example 2]
Next, with reference to FIG. 5, other operation examples in the training support method using the training support system 1 and their effects will be described. FIG. 5 is a flowchart showing an example of a processing procedure in the training support method according to this operation example. This operation example has the same configuration as the processing procedure in the operation example 1 except that the sixth step S6 to the eighth step S8 are executed following the execution of the fifth step S5. The sixth step S6 to the eighth step S8 may be performed immediately after the fifth step S5 is performed, or may be performed at a later date, for example.

(6th step S6)
In the sixth step S6, the user U is provided with exercise in a normal pressure low oxygen concentration environment (so-called hypoxic training) as running training. At that time, the guideline value of the exercise speed in the training is determined based on the index set in the fifth step S5. Specifically, the exercise speed at which training is started can be the adjusted exercise speed set in the fifth step S5, or a speed slightly slower than the speed. In the hypoxic training here, since the exercise ability of each user is different, the set index is also different for each user. Therefore, the normal pressure low oxygen concentration environment of the private room or the normal pressure air of low oxygen concentration is provided to each user. It is desirable to perform in an environment using a so-called hypoxic mask that can be provided. Further, as a normal pressure low oxygen concentration environment, an oxygen concentration corresponding to an altitude of about 1000 m to about 5000 m can be realized by a low oxygen generator using a known membrane separation method, for example. In addition, when running on a treadmill, the endless rotating belt is rotating, so if you run without tilting, you will get a feeling of running just by jumping upwards, so you can get the same feeling as running outdoors. Is desirable to travel at an inclination of, for example, 1% to 2%.

Further, in the sixth step S6, in addition to the index set in the fifth step S5, the oxygen concentration and / or exercise according to the experience value of running by the user U or the experience value of hypoxic training. It is preferable to adjust the speed. For example, the user U, who has little experience in running or high-intensity training, may set the oxygen concentration in a semi-high altitude (1000 m to 1600 m) environment at the initial stage of training and adjust the exercise speed to be slightly higher. On the other hand, in the case of the user U who has abundant running experience, the oxygen concentration of about the upper limit (1600 m) of the semi-highlands may be applied at the initial stage of the start of training, and the exercise speed may be adjusted somewhat conservatively. As a result, it is possible to suppress a rapid decrease in arterial oxygen saturation (SpO ₂ ) and perform safe training. Even in this case, it is desirable to perform training under the control of monitoring arterial oxygen saturation (SpO ₂ ), heart rate, and exercise speed, as performed in the following seventh step S7.

(7th step S7)
In the seventh step S7, the arterial oxygen saturation (SpO ₂ ), heart rate, and exercise rate of the user U undergoing hypoxic training are continuously or intermittently and regularly or irregularly monitored. For example, when performing about 30 minutes to 40 minutes hypoxia training, for example, arterial oxygen saturation every 10 to 15 minutes (SpO _2), heart rate, and by checking the rate of motion, arterial oxygen saturation (SpO ₂ ) Is below a predetermined value (for example, 80% to 90% or 85%), it is possible to carry out management such as adjusting the exercise speed and oxygen concentration to carry out safer training. In addition, hypoxia training from the next time onward will be carried out with the same control values as the previous time, and if the heart rate and arterial oxygen saturation (SpO ₂ ) decrease, the running speed will be increased or the oxygen concentration will be decreased (altitude). You may make adjustments such as raising).

(8th step S8)
Further, in the eighth step S8, preferably, the conditions shown in (1) to (3) are satisfied so as to satisfy at least one of the conditions shown in (1) to (4) below. As such, or to meet the conditions of (1) and (4), the exercise rate and / or oxygen concentration in hypoxic training is adjusted.
(1) Conditions under which the arterial blood oxygen saturation (SpO ₂ ) is equal to or higher than a predetermined value (for example, 80% to 90% or 85%) (2) The heart rate is equal to or lower than the anoxic work threshold (AT). (3) Conditions under which the heart rate is equal to or higher than the heart rate corresponding to the aerobic work threshold (AeT) (4) The heart rate is from the heart rate corresponding to the anoxic work threshold (AT). Conditions that are larger than the number by a predetermined value (for example, about the upper limit value near the heart rate corresponding to the anoxic work threshold (AT))

Hypoxia training is roughly divided into a method of applying a high-intensity exercise load (training exceeding the usual exercise intensity) and a method of applying the usual exercise intensity. In both cases, in an environment with a low oxygen concentration. By training, effects such as improvement of aerobic capacity, fat burning effect, increase of mitochondrial mass, strengthening of muscle strength, and improvement of lactic acid utilization ability can be obtained in a relatively short time. Therefore, for example, while managing so as to satisfy the condition of (1), the heart rate is equivalent to the anaerobic work threshold (AT) to the aerobic work threshold (AeT) under the conditions of (2) and (3). By performing between the values (exercise intensity corresponding to (β) described later), it is possible to effectively improve the aerobic capacity from beginners to advanced people in exercise / running.

In addition, for intermediate and advanced people who have exercise / running habits, it is effective to perform hypoxia training as a training method with a load that cannot be performed outdoors. Therefore, for such intermediate and advanced persons, for example, while managing so as to satisfy the condition (1), the anaerobic work threshold (AT) or a lower heart rate lower than that under the condition (4) is low. By performing oxygen training (exercise intensity corresponding to (γ) described later), maximal oxygen uptake (VO _2max ) is increased, anoxic work threshold (AT) or lactate work threshold (LT) is improved, and lactate. It is possible to efficiently improve athletic ability such as strengthening tolerance, improving aerobic capacity, and strengthening muscle strength.

In addition, by carrying out hypoxic training with a guideline value based on an appropriate index set in the fifth step S5, training for improving endurance athletic ability can be further optimized.

[Operation example 3]
In this motion example, when the type of exercise is a combination of both running exercise and bicycle exercise (triathlon or duathlon), the first step is for the exercise to be performed earlier in the exercise competition. And after the second step is carried out, the third step is carried out for the exercise to be carried out in the later order in the exercise competition. The first step S1 to the third step S3 are equivalent to the steps described in the operation example 1.

That is, for example, in the case of a triathlon, a bicycle exercise (motorcycle) is performed before a running exercise. Therefore, after performing the first exercise motion (motorcycle power meter or indoor cycle) in the first step S1 and the second step S2 for the motorcycle, all out and measuring the exercise ability, the third step S3 for running ( Perform two-step measurement with a treadmill). Since the running motion is different between the running exercise and the bicycle exercise, the muscles and fatigue used are also different. Therefore, after measuring the athletic ability by driving enough to go all out by bicycle exercise, by taking a break for a certain period of time and starting the measurement in the running motion, the exhalation in the running motion in the physical state after the bicycle exercise is measured. Can be done more accurately. In other words, the exercise load state in the previous competition can be reproduced once, and then an index of appropriate exercise intensity can be obtained.

[Operation example 4]
This operation example is an example of providing (proposing) a training menu suitable for the user U based on the measurement result and the index setting result in the operation example 1. That is, based on the athletic ability data of the user U, at least one of (α) to (γ) shown below, or at least two or more combinations, more preferably all combinations, of the user U. It is set as a training menu or notified to the user U as a training menu. In this case, for example, weekly, according to the training principle, training plans in various heart rate zones can be combined and proposed to the user. Further, in particular, by determining the exercise speed represented by the heart rate corresponding to the anaerobic work threshold (AT) based on the set appropriate index, even more effective training becomes possible.

(Α) Intense exercise such that the heart rate is between the maximum heart rate and the heart rate corresponding to the anaerobic threshold (AT) (high-intensity training such as interval training and repetition training).
(Β) Intense exercise (improvement of aerobic capacity) such that the heart rate is between the heart rate corresponding to the anaerobic work threshold (AT) and the heart rate corresponding to the aerobic work threshold (AeT). Training for)
(Γ) The heart rate becomes a predetermined value larger than the heart rate corresponding to the anaerobic work threshold (AT) (for example, about the upper limit value near the heart rate corresponding to the anaerobic work threshold (AT)). (Training aimed at increasing AT and exercise intensity (running speed, etc.) at the same AT)

Further, although not particularly limited, for example, when hypoxic training (see operation example 2 described above) is applied as the training of (β) or (γ), the frequency is recommended to be at least once / 10 days. Will be done. In particular, it is considered that the hypoxic training is carried out once a week or more to promote the adaptation to the low oxygen concentration environment (highland environment) and contribute to the improvement of the endurance system ability. For example, as discussed in the reference example below, a user who is undergoing hypoxic training on a regular basis (once a week or more) may lower the oxygen concentration (raise the altitude) and increase the running speed. Heart rate and arterial oxygen saturation (SpO ₂ ) tend to be difficult to increase. In addition, users who have continued hypoxic training for 3 to 6 months tend to have improved VO 2 _max and AT at the time of measurement as exercise ability.

The method of providing the training menu to the user U is not particularly limited, and for example, an appropriate spreadsheet recorded on the cloud that can be shared and edited by a browser is used for one month online. A training program can be designed and shared with the user U so that the training results and the like can be input. It is also possible to give feedback to the user U at a frequency of about once a week, and set the training menu and intensity for the next week in consideration of the training result, the heart rate at the time of implementation, and the degree of subjective fatigue. In particular, by introducing hypoxic training once a week or more, it is possible to provide a combination program of training on level ground and hypoxic training. Furthermore, hypoxic training is not limited to running, and the same effect can be achieved with walks (hypoxic walks) and bikes (hypoxic bikes) in a low oxygen concentration environment, so in both cases, heart rate and arterial blood. Training menus can be designed individually for oxygen saturation (SpO ₂ ), oxygen concentration (altitude), and exercise rate.

[Reference example]
Hereinafter, changes in the athletic ability of a user who has actually regularly performed hypoxic training by the system and method of the present disclosure will be described as a reference example. However, this disclosure is not limited to the following reference examples. The exercise capacity in the following reference example was measured using a wearable respiratory metabolism measuring system (K5: manufactured by COSMED) and a treadmill for measurement as the respiratory metabolism measuring device 3.

(Case 1)
User U1 has performed hypoxic training (8 times / month) for about 3 years, and his athletic ability is VO _2max (68 → 78), AT equivalent heart rate (153 bpm → 157 bpm), and AeT equivalent heart rate (121 bpm). → 127 bpm) and the predicted time for the full marathon (3 hours 2 minutes → 2 hours 48 minutes) have both improved, and the personal best time for the full marathon has been updated from 3 hours 07 minutes to 2 hours 41 minutes. An example of hypoxic training is as follows. Even if the running speed does not change and the oxygen concentration is low (high altitude), the arterial oxygen saturation (SpO ₂ ) does not decrease and the heart rate decreases. As a result, improvement in aerobic capacity was observed.
· May 2017: oxygen 17.0 percent, when run speed 10 km /, SpO ₂ 92% heart rate 120 bpm, treadmill inclination 2%
- 2018, November: oxygen concentration 16.1%, when run speed 9km /, SpO ₂ 97% heart rate 110, treadmill inclination 3%
- May 2019: an altitude of 15.5%, when run speed 10km /, SpO ₂ 96%, heart rate 108bpm, treadmill inclination 5%

(Case 2)
User U2 performed hypoxic training (8 times / month) for about one year, and his athletic ability was VO _2max (56 → 65), AT equivalent heart rate (142 bpm → 158 bpm), and AeT equivalent heart rate (120 bpm). → 122 bpm) and the predicted time for the full marathon (3 hours 28 minutes → 3 hours 3 minutes) have both improved, and the personal best time for the full marathon has been updated from 3 hours 29 minutes to 3 hours 7 minutes. An example of hypoxic training is as follows. Even if the running speed is increased and the oxygen concentration is low (high altitude), the arterial oxygen saturation (SpO ₂ ) does not change and the heart rate decreases. As a result, improvement in aerobic capacity was observed.
- 2018 July: oxygen concentration of 16.7%, run speed 11.5km / time, SpO ₂ 93%, heart rate 131bpm
- 2019 January: oxygen concentration of 15.7%, when run speed 12km /, SpO ₂ 93%, heart rate 123bpm

User U3 has performed hypoxic training (8 times / month) for about _1.5 years, and his athletic ability is VO _2max (45 → 59) and running speed at AT-equivalent heart rate (6 minutes 40 seconds). / Km → 4 minutes 41 seconds / km) and the predicted time for the full marathon (4 hours 41 minutes → 3 hours 17 minutes) have improved significantly. An example of hypoxic training is as follows, and even if the running speed is increased at the same oxygen concentration (same altitude), the arterial oxygen saturation (SpO ₂ ) is less likely to decrease, so the aerobic capacity is improved. Admitted.
- 2018 October: oxygen concentration of 16.7%, when run speed 10km /, SpO ₂ 88%, heart rate 151bpm
- May 2019: oxygen concentration of 16.7%, run speed 11km / time, SpO ₂ 90%, heart rate 155bpm

(Case 4)
User U4 conducted hypoxia training (4 times / month) for about a year, but the estimated time for the full marathon dropped slightly from 3 hours 30 minutes to 3 hours 36 minutes. An example of hypoxic training is as follows, and it seems that the arterial oxygen saturation (SpO ₂ ) value drops too much during training, and it is necessary to adjust the running speed to make it slower. It is presumed that the fact that SpO2 dropped too low and the load became excessively high led to a drop in the predicted time for the full marathon.
・ October 2018: Oxygen concentration 16.7%, running speed 10km / hour, SpO282%, heart rate 101bpm

(Case 5)
User U5 conducted hypoxia training (4 times / month) for about a year, but the estimated time for the full marathon dropped from 2 hours 49 minutes to 3 hours 00 minutes. In hypoxic training, the arterial oxygen saturation (SpO ₂ ) value was constantly below 90%, and it is presumed that the performance deteriorated due to the accumulation of fatigue.
