To the BPM of Accordingly, the user's heart rate can reach the target heart rate more quickly.

The receiving of the user input includes receiving at least one of a warm-up exercise for increasing the user's heart rate, a main exercise for maintaining the user's heart rate, and a summary exercise for reducing the user's heart rate. .

In the step of outputting the binaural beat and the sound source, outputting a binaural beat having a frequency of 40 Hz to 50 Hz in the warm-up exercise, and outputting a binaural beat having a frequency of 12 Hz to 15 Hz in the main exercise And, by outputting a binaural beat having a frequency of 3Hz to 8Hz in the summary exercise, the exercise concentration effect is maximized.

In the step of varying the BPM, in the warm-up exercise, the BPM is gradually increased by a predetermined control period, in the main exercise, the BPM is maintained, and in the cleanup exercise, the BPM is gradually decreased by a predetermined control period. . Accordingly, the effect of effective aerobic exercise can be expected.

The treadmill of the present invention variably controls the beats per minute (BPM) of the sound source, thereby helping the user's heart rate to reach the target heart rate quickly. In addition, when the user's heart rate is within the stable range of the target heart rate, the treadmill maximizes exercise efficiency in this exercise by maintaining the BPM of the sound source.

The controller 210 may set the target heart rate to a first target heart rate or a second target heart rate lower than the first target heart rate according to the exercise mode. The warm-up exercise aims to increase the user's heart rate until the user's heart rate reaches the maximum heart rate for efficient aerobic exercise, and this exercise aims to maintain the user's heart rate at the maximum heart rate. The target heart rate in the mode and this exercise mode may be the same. On the other hand, since the organized exercise mode aims to return the user's heart rate to the normal heart rate, it may be lower than the target heart rate in the warm-up exercise mode and the main exercise mode. The controller 210 may set the target heart rate in the warm-up exercise mode and the main exercise mode as the first target heart rate, and set the target heart rate in the summary exercise mode to a second target heart rate lower than the first target heart rate.

Meanwhile, the first frequency may be included between 40Hz and 50Hz, the second frequency may be included between 12Hz and 15Hz, and the third frequency may be included between 3Hz and 8Hz. Accordingly, the exercise concentration effect can be maximized.

In addition, the controller 210 may calculate a target heart rate according to the exercise mode and may change the BPM of the sound source based on the target heart rate.

In more detail, the first sound source output control unit 235 in the control unit 210 may increase or decrease the BPM until the initial heart rate falls within a preset stable range of the target heart rate. This can serve to promote an increase or decrease in heart rate.

In addition, the first sound source output control unit 235 in the control unit 210 may maintain the BPM when the initial heart rate is within a preset stable range of the target heart rate. This is to ensure more reliably maintaining the heart rate.

The first sound source output control unit 235 in the control unit 210 may increase or decrease the BPM stepwise during the first control period during variable control of the BPM, and may maintain the BPM during the second control period after the first control period. . This is to prevent a sudden increase or decrease in heart rate.

The control unit 210 may be implemented with a single processor or a plurality of processors, but is not limited thereto and may be implemented in various ways.

The sensor unit 290 may detect the user's biometric information, tilt, and the like. For example, the sensor unit 290 may detect a user's heart rate, blood flow, blood pressure, body temperature, body mass index (BMI), biorhythm, weight, and the like.

The sensor unit 290 may be disposed on the handles 160a and 160b, the base frame 110, the operation panel 150, or the like according to the sensing purpose.

The driving unit 310 may drive the driving motor 311. The driving unit 310 may adjust the rotational speed of the driving motor 311 under the control of the controller 210.

The tilt adjustment unit 320 may drive the lifting motor 321. Depending on the embodiment, the inclination adjusting unit 320 may further include a hydraulic cylinder. The slope adjustment unit 320 may change the slope of the terrain by adjusting the base frame 110 to a predetermined slope.

Meanwhile, the internal block diagram of the treadmill 100 shown in FIG. 3 is only exemplary, and other general-purpose components other than the components shown in FIG. 3 may be further included in the treadmill 100 of the present invention. It can be understood by those of ordinary skill in the technical field related to the present embodiment.

4 is a diagram showing a natural increase or decrease in heart rate through conventional walking, running, and the like.

Referring to the drawings, in order for exercise such as walking and running to lead to effective aerobic exercise (eg, body fat decomposition, etc.), the user's heart rate is 70% or more of the maximum heart rate (bh) (hereinafter, the minimum heart rate) to the maximum heart rate (bh ) Should be included in the stable range. This is because when aerobic exercise such as walking or running exceeds the maximum heart rate (bh), it is easy to convert to anaerobic exercise due to overtraining, and when it is less than the minimum heart rate (bl), the efficiency of decomposing body fat per unit time decreases.

Meanwhile, the maximum heart rate (bh) for effective aerobic exercise may be defined by the KARVONEN formula, but the present invention is not limited thereto. For example, the maximum heart rate (bh) for effective aerobic exercise of the present invention may be calculated by a regression equation based on sampling according to age groups, or may be calculated by further considering special variables such as disease and unusual exercise history.

4 is a diagram showing a natural increase or decrease in heart rate through conventional walking, running, and the like.

In FIG. 4, in the warm-up exercise mode (M1) in which the user's heart rate is increased, the heart rate gradually increases to reach the minimum heart rate (bl), which is the lower limit of the stable range at the time T1. However, in FIG. 4, since the heart rate depends only on a natural increase such as walking or running, it takes a long time for the heart rate to reach a stable range as described later.

In addition, in FIG. 4, after the user's heart rate reaches a stable range, since there is no external stimulus that can maintain the exercise concentration in this exercise mode (M2) that maintains the user's heart rate, the user's heart rate is stabilized. Difficult to keep in range Even as shown in FIG. 4, the user's heart rate may not reach the stable range due to a decrease in concentration.

Likewise, after this exercise mode (M2), even in the organized exercise mode (M3) that reduces the user's heart rate, the tension is not easily relieved because the heart rate depends only on a natural decrease, and the user's heart rate reaches the normal heart rate as described later It takes a lot of time (T2 in FIG. 4) to do so.

The present invention is to solve such a problem, and proposes a method to maximize exercise efficiency.

5 is a flowchart showing a control method of a treadmill according to an embodiment of the present invention, and FIG. 6 is a view referred to in the description of FIG. 5.

In more detail, FIG. 6 is a diagram illustrating an increase or decrease in heart rate according to variable control of a binaural beat and variable BPM control of a sound source.

Referring to the drawing, the input unit 220 may receive a user input for an exercise mode (S410). For example, the input unit 220 includes a warming up exercise mode M1 that increases the user's heart rate, a main exercise mode M2 that maintains the user's heart rate, and a summary exercise mode that reduces the user's heart rate. At least one user command among (M3) may be input.

According to an embodiment, the controller 210 may generate one exercise program leading to the warm-up exercise mode M1, the main exercise mode M2, and the organized exercise mode M3.

The biometric information acquisition unit 231 may obtain the user's biometric information (S430). For example, the biometric information may be heart rate information. The biometric information acquisition unit 231 may acquire the user's heart rate information through the sensor unit 290 provided in the treadmill 100. Alternatively, the biometric information acquisition unit 231 may acquire the user's heart rate information through a first external device (not shown) connected to the communication unit 260.

The audio output unit 240 may output a binaural beat corresponding to the exercise mode and a sound source of a BPM corresponding to the user's initial heart rate (S450). The audio output unit 240 may output a binaural beat and a sound source of a predetermined BPM through speakers 155a and 155b provided in the treadmill 100. Alternatively, the audio output unit 240 may output a binaural beat and a sound source of a predetermined BPM through a second external device (not shown) connected to the communication unit 260. Alternatively, the audio output unit 240 may output a binaural beat and a sound source of a predetermined BPM through a third external device (not shown) connected to the interface unit 270.

Specifically, the control unit 210 provides the audio output unit 240 to output a binaural beat having a frequency of 40Hz to 50H in order to induce the user's awakening state in the warm-up exercise mode M1 that increases the user's heart rate. Can be controlled. In the warm-up exercise mode (M1), the user's brain waves are awakened and beta waves are induced to maintain tension.

The controller 210 may control the audio output unit 240 to output a binaural beat having a frequency of 12 Hz to 15 Hz in order to improve the user's concentration in this exercise mode M2 that maintains the user's heart rate. . In this exercise mode (M2), a sensory motor rhythm (SMR) wave is induced to the user's brain waves, thereby improving the user's exercise concentration.

The controller 210 may control the audio output unit 240 to output a binaural beat having a frequency of 3 Hz to 8 Hz in order to calm the user's arousal state in the organized exercise mode M3 to reduce the user's heart rate. have. In the organized exercise mode (M3), theta waves are induced to the user's brain waves to relax muscles, reduce pain, and help recover from fatigue and improve physical condition.

Meanwhile, the controller 210 may approximate the user's initial heart rate, calculate an initial BPM of the sound source, and control the audio output unit 240 to output the sound source of the initial BPM.

For example, when the initial heart rate is 73 bit/min, the BPM of the sound source is rounded to 70 bpm, and when the initial heart rate is 136 bit/min, the BPM of the sound source is rounded to 140 bpm to calculate the initial BPM of the sound source, so that the sound source of the initial BPM is output. The audio output unit 240 can be controlled. Accordingly, the calculation speed can be increased.

The controller 210 may calculate a target heart rate according to the exercise mode (S470).

The target heart rate may vary according to the exercise mode. For example, the target heart rate in the warm-up exercise mode and this exercise mode may mean a maximum heart rate (bh) for effective aerobic exercise. Alternatively, the target heart rate in the organized exercise mode may mean a normal heart rate.

The target heart rate may vary according to the user's age, gender, and the like. Accordingly, according to an embodiment, the present invention may further include a step of receiving at least one of the user's age and gender before step S410. For example, a 35-year-old normal adult male may have a maximum heart rate of 183 bit/min, and a normal heart rate of 60 bit/min.

The controller 210 may change the BPM based on the target heart rate (S490). Changes in BPM can facilitate an increase or decrease in the user's heart rate. This is because the user's heart rate tends to synchronize with the sound source's BPM. Accordingly, the user's heart rate may be significantly variable than the natural increase or decrease.

Specifically, the controller 210 may increase or decrease the BPM until the initial heart rate falls within a preset stable range of the target heart rate. In addition, when the initial heart rate is within a preset stable range of the target heart rate, the BPM may be maintained. In this case, the stability range may mean more than 70% of the target heart rate. For example, a 35-year-old normal adult male may have a stable range of 128.1 bit/min, 70% of 183 bit/min.

In FIG. 6, when the BPM needs to be increased in the warm-up exercise mode M1, the controller 210 may increase the BPM step by step during the first control period Tc1. For example, the control unit 610 may increase the BPM by 1 bpm per minute during the Tc1 control period. At this time, the user's heart rate may increase in synchronization with the BPM.

On the other hand, since the sudden increase in heart rate may exert an excessive burden on the user, the controller 210 may maintain the BPM during the second control period Tc2 after the first control period Tc1. In order to increase the heart rate efficiently, the size of the second control period Tc2 may be set smaller than that of the first control period Tc1 (Tc1>Tc2).

The controller 210 may increase the BPM step by step until the initial heart rate falls within a preset stable range of the target heart rate. According to the BPM variable control of the control unit 210, the user's heart rate gradually increases to reach a stable range at T3. For example, the user's heart rate may gradually increase at 73 bit/min and become 132 bit/min at T3.

The treadmill 100 of the present invention induces a beta wave to the user's brain wave in response to the warm-up exercise mode (M1), and increases the BPM to promote an increase in heart rate, and thus the user in a shorter time compared to FIG. 4 Is within the stable range (T3<T1).

The controller 210 may maintain the BPM in this exercise mode M2 in which the initial heart rate is included in a preset stable range of the target heart rate. For example, the controller 210 may maintain the BPM of the sound source at 132 bpm in the exercise mode M2. The treadmill 100 of the present invention induces a sensory motor rhythm (SMR) wave to the user's brain wave in response to the exercise mode (M2), and maintains the BPM to prevent the heart rate from fluctuating. The user's heart rate can be more reliably maintained.

When the BPM needs to be reduced in the organized exercise mode M3, the control unit 210 may gradually decrease the BPM during the first control period Tc1. For example, the control unit 610 may decrease the BPM by 1 bpm per minute during the Tc1 control period. At this time, the user's heart rate may be reduced in synchronization with the BPM.

On the other hand, since a sudden decrease in heart rate may exert an excessive burden on the user, the controller 210 may maintain the BPM during the second control period Tc2 after the first control period Tc1. Likewise, in order to increase the heart rate efficiently, the size of the second control period Tc2 may be set smaller than that of the first control period Tc1 (Tc1>Tc2).

The controller 210 may gradually decrease the BPM until the user's heart rate falls within a preset stable range of the target heart rate. According to the variable control of the BPM of the control unit 210, the user's heart rate gradually decreases to reach a stable range at T4. For example, the user's heart rate may gradually decrease from 132 bit/min to 64 bit/min at T4.

The treadmill 100 of the present invention induces the theta wave to the user's brain wave in response to the organized exercise mode (M3), and reduces the BPM to promote a decrease in heart rate, so that the user's Heart rate is within the stable range (T4<T2).

Meanwhile, the controller 210 may control a message corresponding to each exercise mode to be output through the audio output unit 240 and/or the display unit 250. In this case, the message may be a promotion message capable of promoting an exercise effect corresponding to each exercise mode. The audio output unit 240 may output the promotion message as a voice. The display unit 250 may output the promotion message as a graphic object.

For example, the controller 210 may control the audio output unit 240 and/or the display unit 250 to output a message (awakening message) useful for image training in the warm-up exercise mode M1.

In addition, the controller 210 may control the audio output unit 240 and/or the display unit 250 to output a message (encouraging message) that is helpful for motivation in the exercise mode M2.

In addition, the controller 210 may control the audio output unit 240 and/or the display unit 250 to output a message (relaxation message) that is helpful for mental and physical stability and condition recovery in the organized exercise mode M3. .
