Generally, we are measuring maximum oxygen uptake and maximum heart rate to identify cardiorespiratory capabilities for various therapies and exercise regimens.

The maximum oxygen uptake is the maximum energy obtained by aerobic energy metabolism per unit time at the limit of aerobic capacity, which means the maximum amount of oxygen that the human body can use for energy production. The maximum oxygen uptake is known as a maximum oxygen uptake ability that can be achieved by increasing the exercise intensity of an individual and is known to have a correlation with cardiopulmonary capacity, endurance of the whole body, and is used as an index of physical fitness.

The present invention also provides a method for measuring cardiopulmonary capacity using a treadmill.

Referring to FIGS. 1 and 2, a method of measuring cardiopulmonary capacity using a treadmill according to an embodiment of the present invention may be started from step S11 in which information on the sex, weight, . In this step S11, the exerciser inputs his / her gender, weight and height information through the input unit 11 and the exercise method using the treadmill used for measuring the cardiopulmonary capacity.

The step S12 of calculating the treadmill speed and the degree of inclination corresponding to the different exercise loads set for each of the plurality of exercise steps may be executed according to the sex, weight information and the exercise method of the inputted exerciser. This step S12 may be performed by the treadmill drive information calculation unit 12 described above. As described above, in step S12, the treadmill drive information calculation unit 12 calculates the treadmill speed and tilt according to the gender and weight information of the exerciser and the exercise method, Using the table, the dreadmill speed and the inclination can be appropriately set according to the exercise system, the sex of the exerciser, and the weight of the exerciser within the range set in Table 1. [

Thereafter, step (S13) of driving the treadmill according to the dreadmill speed and the degree of inclination calculated in step S12 and providing the exerciser with the exercise may be executed. The driving of the treadmill 14 may be performed by the treadmill driving unit 13 and the treadmill driving unit 13 drives the treadmill 14 to maintain the speed and the inclination of the treadmill 14 calculated by the treadmill driving information calculating unit 12 So that the exercise load set for each exercise stage can be provided to the exerciser.

Then, step S14 of detecting the heart rate of the exerciser exercising with the exercise load provided in step S13 may be executed. In step S14, the heart rate sensor 15 attached to the body of the exerciser can be used to detect the heart rate per exercise step of the exerciser.

The step S15 of calculating the maximum oxygen uptake amount and the maximum heart rate of the exerciser according to the heart rate of the exercise phase of the exerciser detected in step S14 and the sex, weight, height, and exercise mode of the exerciser may be executed.

The step S15 may be performed by the cardiopulmonary capacity computing unit 16 and may be performed by using the heart rate of the exerciser detected during a predetermined time interval immediately before the end of each exercise step for a plurality of exercise steps, Can be calculated. For example, in step S15, the maximum oxygen uptake amount and the maximum oxygen uptake amount are calculated by using the average value of the heart rate of the exerciser detected from 10 seconds before the end of each of the plurality of exercise steps to the end of each exercise step, The maximum heart rate can be calculated.

In addition, in step S15, the maximum oxygen intake amount and the maximum heart rate of the exerciser can be calculated by the above equation (1) through (8).

Hereinafter, the process of deriving and verifying the regression equations of Equations (1) to (8) will be described in detail.

In order to verify equations (1) to (8) for measuring the maximum oxygen uptake and the maximum heart rate provided by the present invention, a total of 60 persons, 30 healthy persons and 20 healthy persons, The maximum exercise load test and the exercise technique provided in the cardiopulmonary capacity measurement method according to the embodiment of the present invention were applied. Thereafter, when the exercise provided by the method for measuring cardiorespiratory performance according to the embodiment of the present invention is applied based on the maximum oxygen intake amount and the maximum heart rate measured through the maximum exercise load exercise, the accuracy of the measured oxygen intake amount and heart rate is calculated Thereby verifying the cardiopulmonary capacity measurement method according to one embodiment of the present invention.

- Maximum exercise load test

Modified Bruce Protocol was applied to maximal exercise load test. The Bruce protocol, which is the most common protocol for testing exercise loads using a treadmill, is a protocol suitable for a normal person or a person with a high risk factor. However, the protocol is too expensive for the first time, Modified Bruce protocol was applied.

In the maximal exercise test using the modified Bruce protocol, as shown in Table 2 below, the load of the initial start of exercise was maintained at a constant speed of 1.7 mph, and the load was maintained at 0% for 3 minutes and continued for 9 minutes Until then, the slope was increased by 5% every 3 minutes and then increased by 2% every 3 minutes.

step Time (min) Speed (mph) slope(%) One 3 1.7 0.0 2 3 1.7 5.0 3 3 1.7 10.0 4 3 2.5 12.0 5 3 3.4 14.0 6 3 4.2 16.0 7 3 5.0 18.0 8 3 5.5 20.0 9 3 6.0 22.0

- the motion provided by the cardiopulmonary capacity measuring device according to one embodiment of the present invention

Exercise load (speed and inclination) of the treadmill at each exercise step was set in the range as shown in Table 1 for the above-mentioned experiment participants to provide exercise. The 'Walking' test increased the slope and increased the exercise load, and the 'run' test increased the exercise load by increasing the movement load (speed) and the slope, .

- analysis -

As shown in FIG. 3, the trend of the heart rate per exercise step provided in the method for measuring carding ability according to an embodiment of the present invention is derived, and from each time of 10 seconds before the end of the exercise step, The average heart rate was determined until the end of the exercise phase and was determined as the heart rate of the exercise phase.

Next, regression analysis was applied. Regression analysis is a method of calculating the dependent variable through the regression equation which is a significant independent variable by identifying the relationship with various independent variables in order to estimate the dependent variable. There is a significant correlation between the independent variables In this case, the independent variable with the largest correlation is removed from the regression equation.

In the exercise provided in the method of measuring cardiorespiratory ability according to an embodiment of the present invention, the maximum oxygen uptake and the maximum heart rate are dependent variables, and the age, weight, height, and heart rate of each exercise interval are independent variables.

Table 3 shows the age, height, weight information and maximum oxygen uptake (VO2max) and maximum heart rate (HRmax) of the participants participating in the experiment as measured by the maximum exercise test described above.

gender personnel age Height (cm) Weight (kg) VO2max HRmax south 30 22.43 + - 1.50 173.55 + - 6.22 71.77 + - 7.93 58.68 + - 5.48 192.97 + - 11.24 female 30 22.43 + - 1.50 160.10 ± 5.74 56.08 + - 7.74 44.74 ± 5.96 190.97 + 9.59

In the analysis of the motion provided by the method of measuring cardiorespiratory ability according to an embodiment of the present invention, first, in order to verify whether the motion is designed so that the increase in the motion load is clearly displayed for each motion phase, And that there is a valid difference. For the analysis, this table t-test was applied and it was confirmed that there was a significant difference between groups in all parent groups (p-value <0.001). Table 4 shows the heart rate per segment in each group.

group walking jump HR1 HR2 HR3 HR4 HR1 HR2 HR3 HR4 south Average 90.80 101.39 113.13 128.06 90.86 128.85 150.29 163.56 Standard Deviation 9.57 10.47 12.18 14.70 9.35 18.82 20.82 20.42 female Average 103.34 115.05 127.81 145.13 106.32 136.75 161.82 176.42 Standard Deviation 9.91 10.97 14.36 18.69 9.67 17.17 15.48 16.74

In Table 4, HR1 to HR4 are the heart rates measured at each exercise step.

Next, we analyzed the state of heart rate between exercise methods. In order to obtain the statistical evidence to explain the characteristics of the exercise method, we compared and analyzed the state of the heart rate during the exercise phase between walking and running. In this analysis, the table t-test was applied, and no difference was found between the two exercise methods in the heart rate HR1 of the first exercise phase having the running speed and the inclination, and the heart rate HR2 , HR3, and HR4) (p-value <0.001). This is because the changes in heart rate vary according to the walking and running motion even under the same exercise load. In other words, although the physical load is the same, it is confirmed that the heart rate is different according to the correlation between the speed and the inclination. In particular, the jump movement showed a higher heart rate compared to the walking exercise, which indirectly confirms that the change in speed is more influential on the change in heart rate than the gradient.

A regression equation such as Equations (1) to (8) was calculated through regression analysis as described above.
