The exercise equipment management server 400 stores basic personal information data of people using exercise facilities as a server in the exercise facility and receives and stores exercise prescription data of the user from the exercise equipment terminal 300, And sends the data requested by the terminal 300 to the exerciser terminal 300 when the data is requested.

The exercise device terminal 300 may be in data communication with the exercise device management server 400 through the exercise device output port 395.

Next, a method for estimating VO2max by individual in the present invention will be described.

Basically, in order to estimate VO2max, the time (minute) required to reach the ventilation threshold based on the ventilation threshold determined by the user's specific exercise test (Modified Balke Protocol), and the individual heart rate HR), and then estimates individual VO2max by body information, estimated VO2, time, and heart rate. It is estimated to be discriminated between male and female, and the exercise intensity is determined based on the estimated VO2max.

3 is a flowchart for estimating VO2max in the present invention.

The modified Balke protocol test is performed (S220), the intensity is increased (S230), the ventilation threshold value is checked (S240), and if the ventilation threshold is not set, the ventilation threshold value is found.

In the case of the ventilation threshold value, the time (minute) at which the ventilation threshold is reached and the individual heart rate HR at that time are obtained (S250).

Based on the time (minutes) to reach the ventilation threshold and the individual heart rate (HR) at that time, the individual VO2 is estimated first (S260).

Then VO2max is estimated by body information, estimated VO2, time, and heart rate. At this time, it is estimated to be discriminated between male and female, and the exercise intensity is determined based on the estimated VO2max.

That is, in order to estimate VO2max, a user's exercise ability test should be performed first. In order to estimate VO2max, a VO2 value and a slope varying to VO2max are required. In order to obtain the point at which ventilation thresholds are generated, a modified Balcke protocol must be tested on the treadmill. It is possible to estimate the VO2 in which the exercise capacity of the individual is taken into consideration by using the reaching time (minute) when the ventilation threshold is reached according to the exercise ability of the individual, and the user's heart rate (HR)

The VO2 estimation equation is divided into male and female, and the equation is as shown in Equation 1

Here, HR is the user's heart rate when the ventilation threshold is reached, and time is the time (minutes) when the ventilation threshold is reached.

To estimate the VO2max, the reaching time (minutes) to the ventilation threshold, which was used to estimate the individual VO2 and VO2, and the heart rate at that time are used again. In addition, we provide non-invasive and non-invasive estimation methods optimized for personal exercise ability and personal biometric information by adding individual body information to this parameter to estimate VO2max again to improve accuracy. The VO2max estimation equation is classified into male and female, and is expressed by Equation (2). The parameter used in the VO2max estimation equation is different for men and women, and the parameters applied vary because lifestyle, muscle, and fat ratios between men and women are relatively different from those of the same sex.

Systolic blood pressure, systolic blood pressure, and VO2.rest (ml / kg / min) were measured in the steady state, and body fat mass was expressed as body fat mass in kg, age in waist, waist circumference in SBP VO2 < / RTI > var.time (min) means time change (minute) from the start of exercise to ventilation threshold, and time.VT (min) means time (minute) when ventilation threshold is reached. Obesity represents obesity and is obtained by Equation (3).

Here, weight is weight, height is height, ideal.weight is (height - 100) x0.92 for man and (height - 100) x0.86 for woman.

slope.VO2 is the slope of the value of VO2 change over time from the start of exercise to the ventilation threshold.

The following describes the parameters and criteria for biofeedback.

First, the heart rate (HR) is described.

Based on the HR information measured in real time during the exercise, the target HR range is set during the exercise, and if HR higher than the target heart rate range is maintained once for one minute, the exercise is performed one step lower than the temporarily prescribed exercise intensity And is automatically controlled so that safe exercise can be continued by resetting the exercise intensity to one level higher than the prescribed exercise intensity when HR lower than the target heart rate area is maintained for 3 minutes. If the prescribed exercise is not suitable for the user for 2 weeks and the exercise prescription change due to HR is performed more than 3 times higher than the target heart rate area, the exercise level is automatically reset so that the prescription exercise regimen can be performed. The target heart rate area is divided into the disease group and the normal group, and the exercise prescription interval is expressed by Equation (4).

Where maxHR is the maximum heart rate, and restHR is the resting heart rate.

Second, heart rate variability (HRV) is explained.

The LF / HF ratio, which is calculated as the ratio of high frequency (HF) and low frequency (LF) regions obtained through the power spectrum density (HRD) (1.5-2) more than three times in a state that is twice or more than the stable range (1.5 ~ 2), it is automatically reset to a lower intensity than the prescription exercise regimen. Since the activation of the LF region is accelerated at the beginning of the movement and the LF / HF ratio can have a value much larger than the stable range, the out-of-range count is excluded at the beginning of the exercise. The count will start from 50% of the prescribed exercise.

The following describes the QT interval (QT interval) for the third time.

The QT interval at rest is measured and set as the reference value. If abnormal abnormal sudden increase occurs more than 3 times within 2 weeks rather than increase due to exercise through real-time monitoring during exercise, it is automatically reset to lower intensity than prescribed exercise regimen. The Q wave interval was calculated at the point where the QRS wave starts and the T wave ends at the end of the T wave.

FIG. 4 is an example of a flowchart for determining exercise prescription by separating a disease group and a normal group according to the present invention.

Upon receiving the customized exercise prescription in the fitness center environment and starting the exercise (S310), the user's terminal 100 detects the biometric information of the user's electrocardiogram, PPG, activity level, body temperature, (S320).

The information on the user stored in the exercise equipment management server 400 or the integrated server (not shown) is received and it is determined whether the user belongs to the normal group category or the disease group category (S330). Based on the questionnaire survey, basic physical information, and personal information in advance according to the user, it is divided into categories of the normal group and the disease group by applying the disease diagnosis or the like, and stored in the exercise apparatus management server 400 or the integrated server (not shown) .

If the user is a normal group, HRR (heart rate reserve) of the user is obtained, and the HR of the user is compared with the maximum exercise intensity of the normal group of Equation (4) If the HRR of the user is less than 60% of the HRR for 3 minutes or more (S380) as compared with the minimum exercise intensity of the normal group of the equation (4) in step S360, The intensity is increased (S390).

In addition, if the LF / HF ratio obtained through the frequency analysis of HRV is greater than or less than 4 (S400), it is judged whether the LF / HF ratio is greater than 4 or less than 1, , And if it is more than three times (S410), the exercise intensity is readjusted (S420).

If it is determined that there is an abnormal sudden increase in the QT interval of the electrocardiogram (S430), it is determined that the abnormal sudden increase in the QT interval is three or more times in two weeks. If the QT interval is three times or more (S440) (S450).

If the user is a disease group, the HRR of the user is obtained. If the HRR of the user is greater than the maximum exercise intensity of the disease group of Equation (4) and the user's HR is greater than 1 minute and greater than 75% of the HRR (S460) (S470). If the user's HRR is less than 50% of the HRR for 3 minutes or more (S480), the user's HR is increased compared to the minimum exercise intensity of the disease group of Equation (4) (S490).

In addition, if the LF / HF ratio obtained through the frequency analysis of HRV is greater than or less than 4 (S500), it is judged whether the LF / HF ratio is greater than 4 or less than 1, , And if it is three times or more (S510), the exercise intensity is readjusted (S520).

If it is determined that there is an abnormal sudden increase in the QT interval of the electrocardiogram (S530), it is determined whether the abnormal sudden increase in the QT interval is three or more times in two weeks. If the QT interval is three times or more (S540) (S550).

Here, HRR is the maximum heart rate minus the normal heart rate (resting heart rate).

4, when a customized exercise prescription is received in the fitness center environment and the exercise is started, the biometric information is transmitted to the exerciser terminal 300 through the user terminal 100. FIG. First, based on questionnaires, basic physical information, and personal information, individuals are divided into normal and disease groups by applying disease or not. In the normal group, the exercise intensity is readjusted when it deviates from the target heart rate range, and the necessity of re-adjustment of exercise intensity is determined according to the state of LF / HF ratio (ratio of activity of sympathetic nervous system and parasympathetic nervous system) obtained through PSD analysis of HRV . QT interval likewise performs exercise intensity readjustment if there is a sudden change (especially increase) relative to the steady state value. The two-week recalibration standard is basically performed every two weeks to check for changes in the individual programs since the exercise program, which is provided to the user, is updated every two weeks and consists of a total of 24-week programs.

Fig. 5 is an example of a flowchart for determining exercise prescription in the exercise device terminal of Fig. 2;

In the basic information receiving step, the exercise apparatus calculation processor 320 of the exercise apparatus terminal 300 requests past exercise information, personal basic information, and basic fitness information for the user to the exercise apparatus management server 400, And receives these data from the management server 400 (S110).

The basic personal information includes height, weight, BMI, systolic blood pressure (mmHg), diastolic blood pressure (mmHg), resting heart rate (Rest HR), and maximum heart rate (Max HR). In addition, basic physical strength measurement information includes side step, agility (muscle response), agility (neural response), muscle endurance, instantaneous power (ms), balance, flexibility (Cm) and muscle strength. This information will be measured at the first visit to the fitness center. These are parameters that can be used to confirm the status of the current individual and are used as an element to reset the exercise prescription group (group) and VO2max step again after the 24th week exercise prescription is completed.

(HR) and heart rate variability (HRV) representing cardiovascular information from the electrocardiogram signal and the PPG signal received from the slave module, basic personal information received in the basic information receiving step, basic physical strength measurement Estimates VO2max based on the information, and determines an initial exercise prescription from the estimated VO2max (S120).

In the instrument control step, an instrument control signal of the exercise instrument is generated according to the exercise prescription, and the exercise instrument is controlled (S130).

(HR), heart rate variability (HRV), QT interval (QTc), and body temperature from the bio-signals received from the slave module 110, i.e., electrocardiogram, PPG, body temperature, The signal is compared with the reference range signal stored in the exercise device memory unit 340 to determine whether to change the exercise prescription (S140).

That is, whether or not the exercise prescription is changed is automatically performed, and it is determined based on the living body parameters currently being measured in real time. From the currently measured electrocardiogram, the frequency analysis of the autonomic nervous system changes in heart rate information and heart rate variability is evaluated in real time, and it is continuously monitored in real time whether the present exercise prescription can be properly performed. Based on the power spectrum density (PSD) of the autonomic nervous system in the active frequency region, we analyze the fatigue of the current exerciser and calculate the QT interval / QTc of the electrocardiogram to determine whether to continue, change, . At this time, VO2max values are obtained for each disease, age, and sex in the exercise device memory unit 340, and a reference range for each bio-signal is stored based on the obtained VO2max.

If it is determined that the exercise prescription is to be changed in the exercise prescription re-establishing step (step S150), the exercise prescription is reset and the apparatus control step is returned to step S150.

점수화(기본 개인 정보만으로 얻는 정보에 대한 운동능력평가에서 보정값으로 역할)를 구하여 운동량, 즉운동처방을 결정한다. 즉, 유산소 운동에서의 운동처방은, 최초 피트니스센터 방문으로 얻은 두 가지 정보, 즉, 개인 기본정보와 기초체력 정보를 바탕으로 운동처방 군(群)이 나눠지게 되고, 그 분류는 다시 개인의 VO2max값에 따라 운동처방이 24주 프로그램으로 사용자에게 제공될 수 있다. In case of aerobic exercise, basic information (height, weight, BMI, blood pressure, HR, Max HR), VO2max (substitute measurement value, Elasticity, muscle strength)

The scoring (acting as a correction value in the exercise ability evaluation of the information obtained by only the basic personal information) is determined to determine the exercise amount, that is, the exercise prescription. In other words, the exercise prescription in the aerobic exercise is divided into the exercise prescription group (group) based on the two pieces of information obtained from the first visit to the fitness center, that is, the personal basic information and the basic fitness information, Depending on the value, the exercise prescription can be provided to the user in a 24-week program.

In other words, the exercise prescription is classified as a group of exercise prescription through personal basic information and basic fitness information, and is provided in a manner in which the exercise protocol is presented by VO2max in the classification. The VO2max value is firstly estimated using cardiovascular information, and then VO2max is estimated by lowering the error rate by selectively applying highly correlated personal basic information.

In the case of exercise prescription for anaerobic exercise, exercise prescription is decided by combination of number of times, weight, and number of sets.

In other words, in the case of exercise prescription for anaerobic exercise, 1RM is estimated through 10RM test at the first visit, and the repetition maximum test value is estimated to determine the exercise ability of the exerciser and the number of times, weight, . The one-time maximum repetition rate (1RM) estimation equation is primarily estimated through Wathan's equation (5), which is known to be the least error-prone.

(REPS is a repeating number.)

If it is determined that the exercise prescription is to be changed at the step of determining whether or not to change the exercise prescription, it is determined whether the exercise is stopped by the user (S160) and whether the exercise is terminated due to the end of the exercise protocol (S170) If the movement is stopped, or if the movement is stopped due to the end of the movement protocol, the process is terminated. If the movement is not stopped by the user, or if the movement is not stopped due to the end of the movement protocol,

In the present invention, the bio-information of the user is transmitted to the exercise device terminal through the user terminal while the user wears the user terminal and performs exercise in the exercise device, Based on the data on the server, bio-feedback is performed in real time to control the exercise device.
