Description

  The present invention relates to an aerobic exercise apparatus, and more particularly, to a configuration for setting an efficient fat burning cycle for an exerciser himself by setting exercise conditions with reference to the exerciser's own experience.

In recent years, attention has been focused on improving dietary habits, improving health through exercise, and reducing body fat.
On the other hand, aerobic exercise and anerobic exercise are known as exercises. Among them, aerobic exercise, which is aerobic exercise, is known to be effective for fat burning because it can efficiently convert fat into energy. Yes.

  A device used for aerobic exercise (aerobic exercise) is a bicycle type equipped with a braking mechanism such as a treadmill or an electromagnetic brake having a structure for walking or running on a belt driven by an electric motor or the like. There is an ergometer.

  Maffeton theory is well known as the principle of aerobic exercise.

This theory is an exercise form that incorporates warm-up and cool-down operations of about 15 minutes using the heart rate as an index.
Also in the apparatus used for the aerobic motion mentioned above, what was equipped with the structure for practicing Maffeton theory is proposed (for example, patent document 1).

  In Patent Document 1, in a treadmill that can control the speed following the change of the heart rate, from the pre-exercise heart rate to the heart rate corresponding to the target exercise intensity, the walking speed is determined from the walking speed set in advance. Start, and drive control of the drive source to change the speed of the belt equipped on the treadmill while observing the heart rate change so that the heart rate corresponding to the target temperature It has become.

JP 2002-177413 (paragraph "0007" column)

  In the configuration of the device disclosed in Patent Document 1, warming up and gradually increasing the belt speed from the start of exercise with reference to a map of heart rate and exercise intensity preset in the control unit of the device. An aerobic exercise according to the amount of exercise can be performed by incorporating a cool-down that lowers the belt speed.

However, an exerciser is forced to receive an exercise load corresponding to a change in heart rate in accordance with conditions set in the apparatus in advance, and some exercisers may not meet this condition. Is not taken.
That is, the time when fat burning is started in aerobic exercise may be based on the amount of water and carbon dioxide gas generated when fat is burned and converted into energy. Among these generated components, moisture is discharged out of the body as sweat, so that the athlete can feel that fat burning has started.

However, in the conventional apparatus, even when fat burning is started, the steady exercise state is not switched during warm-up, and accordingly, an excessive amount of exercise must be performed for the exerciser.
When excessive exercise is performed, oxygen uptake, including an increase in heart rate, increases abnormally, and the concentration of blood oxygen tends to increase. There is a risk of causing it.
In addition, if you exercise excessive momentum, especially when it causes a sudden change in momentum, your body will use carbohydrates instead of fat to meet that momentum, which also causes the production of lactic acid. Thus, it becomes difficult to achieve improvement of blood circulation, enhancement of cardiopulmonary function, and reduction of active oxygen due to fat burning, which is the original purpose of aerobic exercise.

On the other hand, it is generally known that replenishment of water is important when performing endurance exercise such as aerobic exercise of this kind, and if 60% of the body's water is discharged by sweat, etc. May cause symptoms.
In conventional treadmills, hydration is often performed by the physical experience of the exerciser and is often not adapted to the exerciser's hydration reduction. In particular, if you are not conscious, you may not rehydrate.

  The object of the present invention is to improve the blood circulation and enhance the cardiopulmonary function by reducing fat, which is the original purpose of aerobic exercise. An aerobic exercise device with a structure that enables health promotion and fat loss by being able to match the exercise experience, and that can recognize hydration required during aerobic exercise regardless of the consciousness of the exerciser Is to provide.

  According to the present invention, the athlete himself / herself is switched to the steady-state exercise state at the time when the athlete himself / herself commands the warming-up executed under the preset driving conditions. It is characterized in that it is possible to select the time to start the combustion motion and thereby avoid giving an excessive momentum. In addition, hydration during aerobic exercise is alerted every predetermined time from the start of the fat burning cycle, so that it can be easily recognized by the athlete, and the mobile body is decelerated during hydration. This prevents hydration in an unstable state.

  In particular, the invention according to claim 1 is an aerobic exercise device that consumes kinetic energy of a body using a moving body driven by a drive source, wherein the drive source is connected to the output side, A first mode switch for switching from a warm-up state based on a preset speed and time from start to a steady motion state, and a first mode switch for switching from the steady motion state to a cool-down state based on the speed and time from stop to stop. A control unit connected to the second mode switch, and the control unit sets a steady motion state when a signal is input from the first mode switch in a process in which the warm-up state is executed. When the signal from the second mode switch is input in the process of executing the steady motion state, And switches the driving condition of the drive source, is characterized by alerting the hydration at a given time warm-up state, at least one constant motion state and a cool-down state as a target.

  According to a second aspect of the present invention, in the aerobic exercise apparatus according to the first aspect, the control unit decelerates the speed of the moving body from the previous speed at a hydration alarm.

  According to a third aspect of the present invention, in the aerobic exercise apparatus according to the first or second aspect, the control unit decelerates the speed of the moving body up to the time of the hydration alarm, and then returns to the original speed after a predetermined time. It is characterized by letting.

  In the present invention, when the athlete himself / herself determines that the fat burning start timing is operated during the warming-up exercise executed based on the drive control conditions set in advance, the warming-up exercise is performed. Even in the course, it is possible to switch to a steady motion state for continuing fat burning, and it is also possible to change the timing of cool-down based on the steady motion state. This makes it possible to set up a fat burning cycle tailored to the physical strength and athletic ability of the exerciser, and forcibly exercises that hydration is necessary when performing aerobic exercise. Can be recognized, and when the water is replenished, it is easy to maintain a state where the moving body can easily catch the ball by deceleration.

  Hereinafter, the best mode for carrying out the present invention will be described by way of examples.

FIG. 1 is an external view of a treadmill which is one of the aerobic exercise apparatuses according to this embodiment.
The treadmill 1 includes a base 2 made of a floor frame, handrails 3 and 4, a console panel 5, a continuous belt 6 and a bottom support leg 7 as main parts.

  The base 2 is provided with a casing 8 in which a lower part of the handrails 3 and 4 is attached at one end in the longitudinal direction, and an electric motor (not shown) for driving the continuous belt 6 is accommodated. In addition, the code | symbol 9 in FIG. 1 is a nozzle which supplies oxygen toward an exerciser as needed.

  Although not shown, the continuous belt 6 is provided with a stretched surface along the longitudinal direction of the base 2, and a pulley (not shown) provided on the casing 8 side corresponding to both ends of the stretched surface and on the opposite side thereof. It is laid around. One of the pulleys is driven by an electric motor located in the casing 8.

The console panel 5 is a control unit to be described later, and a part for displaying instructions and exercise states from the exerciser to the control unit, and details thereof are shown in FIG.
FIG. 2 is a diagram showing the contents of the console panel 5. In FIG. 2, the console panel 5 includes a start switch 5A, a stop switch 5B, an exercise state display unit 5C, and a switch for switching from a warm-up state to a steady exercise state. 1st switch 5D, 2nd mode switch 5E for switching to operation | movement which gradually decelerates from a steady driving state to a stop, the display panel part which displays the calorie consumption by walking, walking distance, time, exercise time, etc. 5F, acceleration / deceleration switches G, 5G ′ and an emergency stop button switch 5H are provided. The second mode switch 5E is a switch used for cool down selection.

Various switch groups and a display unit provided on the console panel 5 are connected to the control unit shown in FIG.
The control unit 100 shown in FIG. 3 is a part that performs drive control of the treadmill 1 and handling various information, and is continuously performed according to a preset exercise cycle, that is, an operating state of the continuous belt 6 and a command from the exerciser. The main part is composed of a microcomputer capable of controlling the operation state of the belt, and a start switch 5A, a stop switch 5B, a first mode switch 5D, a second switch are provided on the input side through an interface (not shown). A mode switch 5E and an emergency stop button switch 5H are connected, and on the output side, a display panel 101 provided with an exercise state display unit 5F and a numerical value display unit 5C and an electric motor drive unit 102 serving as a drive source for the continuous belt 6 are provided. Each is connected.

  In the control unit 100, this type, Maffeton theory known as the aerobic exercise cycle used in the treadmill (for example, Dr. Philip Maffeton, published by Runners Co., Ltd. "Revolutionary aerobic training" Maffeton theory ") ”Page 34), the driving speed and the driving time of the continuous belt 6 are set in advance so as to perform a fat burning exercise cycle that executes a warm-up state, a steady-state motion state, and a cool-down state. The cycle set in advance according to the command is switched to a fat burning exercise cycle tailored to the individual exerciser.

FIG. 4 is a tying chart showing operations executed by the control unit 100 in the present embodiment on the premise of the fat burning exercise cycle based on the above-described Maffeton theory.
In FIG. 4, the timing indicated by the solid line indicates a fat burning exercise cycle based on Maffeton theory in which an exercise state is set with reference to the heart rate.
In this cycle, the blood flow is changed and the aerobic muscles are increased by gradually increasing the heart rate for a predetermined time of about 15 minutes from the start (time indicated by T1 in FIG. 4). A warm-up state that prompts blood supply to the patient, and after a predetermined time has elapsed, a motion cycle (denoted by Ts in FIG. 4) with a predetermined time at a constant speed is continued for a plurality of cycles (Ts × 8 cycles). During a predetermined time (indicated by reference numeral T1 ′ in FIG. 4) from the steady state to the stationary motion state, the body gradually decelerates under the same conditions as the warm-up state to gradually lower the heart rate. A cool-down state is set to prevent stagnation of blood flow.

  On the other hand, the timing indicated by the two-dot chain line indicates a fat burning exercise cycle based on the exerciser's own command. In this cycle, when the first mode switch 5D is operated in the process of the warm-up state (in FIG. 4). , The timing indicated by the reference symbol Ta), the preset warm-up state is interrupted and switched to the steady motion state.

  When switched to the steady operation state, the control unit 100 sets the motion cycle using the speed at the time of switching and a preset time as one cycle, and is the same as in the steady motion state indicated by the solid line. The condition (Ts × 8 cycles) will be executed, but if the exerciser operates the cool-down switch 5E, the vehicle will decelerate using the same condition as the acceleration condition in the warm-up state, and control to stop will be performed. This is executed (timing indicated by reference symbol Ta ′ in FIG. 4).

The operation of the first mode switch 5D is performed on the basis that the athlete himself / herself sweats, which is one of the discharged products, as the start time of fat burning.
For this reason, instead of continuing the forced warm-up state, the fat burning start time corresponding to the athlete himself / herself is selected and the steady motion state is continued. In the steady motion state, the speed set in advance and the predetermined time are set as one cycle, so that the amount of fat burning increases according to the duration time.

In this embodiment, a hydration alarm is issued in the warm-up state, the steady motion state, and the cool-down state.
In other words, it is generally known that retention of moisture is important when performing endurance exercises such as this type of aerobic exercise, and if moisture that occupies 60% of the body is discharged by sweat, etc., dehydration May cause symptoms. Therefore, in the present embodiment, display for prompting hydration is performed on the console panel 5 at predetermined time intervals (timing indicated by reference characters Tb1, Tb2, and Tb3 in FIG. 4) from the warm-up start time. As a display for prompting hydration, for example, as shown by reference numeral 5P in FIG. 2, for example, a form in which a bottle display is turned on is used.

  On the other hand, in the control unit 100, the speed of the continuous belt 6 is temporarily decelerated at the timing when the hydration display is performed every predetermined time. This prevents the athlete from wobbling when taking the hydration posture due to the speed of the continuous belt 6. Note that the console panel 5 is provided with a release switch denoted by reference numeral 5Q when the athlete does not need it during hydration or when the preset deceleration state is forcibly released after hydration. Yes. In the console panel 5 shown in FIG. 2, reference numeral 5J denotes an exerciser's weight input switch, and reference numeral 5K denotes a display column for explaining display contents in the console panel 5.

Since the present embodiment is configured as described above, when the exerciser who is placed on the continuous belt 6 of the treadmill 1 operates the start switch 5A, the control unit 100 executes drive control of the electric motor.
In the control unit 100, a preset fat burning exercise cycle is started when the start switch 5A is operated. In this case, speed increase control of the electric motor is executed so as to start a preset warming state.

  When the exerciser does not operate the first mode switch 5D in the warm-up state, speed control according to the fat burning exercise cycle indicated by the solid line in FIG. 4 is executed. If any one of the speed increasing switch or the speed reducing switch 5G, 5G 'is operated by the exerciser during this control, the speed is switched to the speed increasing or deceleration state corresponding to the operation state. In this embodiment, 1 km / h is set as a speed increase / deceleration range by a single pressing operation.

  Further, when the emergency stop button switch 5H is operated, the emergency stop button 5H is stopped under conditions that avoid sudden stop as much as possible, that is, in a state where the deceleration is increased. As a result, it is possible to prevent the blood from being stagnant and falling, which is likely to occur during a sudden stop or the like, and to prevent the light from drifting or falling.

On the other hand, when the first mode switch 5D is operated by the exerciser in the process of reaching the preset maximum speed and time in the warm-up state, the control unit 100 at the time when the first mode switch 5D is operated. Is registered, and a steady motion state based on the speed is started.
That is, when the preset warm-up state setting time is 15 minutes, if the first mode switch 5D is operated in less than 15 minutes, for example, 5 minutes, 10 minutes, etc., the warm-up state is set. Among the speeds in the acceleration stage, the speed at the time of the operation is used as a reference, and the motion cycle in the steady motion state is executed.
Therefore, when the athlete himself / herself experiences the appearance of sweat generated by fat burning, it is possible to select the transition time to the steady motion state, which is the fat burning continuing motion. Thereby, it is possible to prevent the excessive exercise state in the warming-up state from continuing so-called anaerobic exercise that consumes carbohydrates instead of fat.

  The steady motion state is completed by setting a predetermined time, in other words, by completing the number of cycles. However, if the exerciser selects a speed change in this motion state, the selected speed is maintained. Therefore, a control signal is output to the drive unit 102.

  A cool-down that gradually decelerates is executed when the steady motion state is completed for a predetermined time, in other words, by completing the number of cycles.

  In the cool-down state, when the second mode switch 5E (see FIG. 2) is operated separately from the case where the preset time is continuously performed, even when in the steady motion state, it is forced. Transition to cool-down operation.

On the other hand, the controller 100 performs hydration control at a predetermined timing while monitoring the warm-up state, the steady motion state, and the cool-down state.
The hydration control is executed at predetermined intervals from the start to the end of the fat burning exercise cycle, and the hydration display section 5P (see FIG. 2) on the console panel 5 is sequentially turned on and in accordance with the timing. Reduce the speed of the continuous belt temporarily. After the deceleration state is continued for a predetermined time or when the release switch 5Q is operated, the speed of the continuous belt is returned or maintained to the original state.

  FIG. 5 is a flowchart for explaining the operation of the control unit 100 described above. In FIG. 5, when the start switch 5A is turned on, drive control for the continuous belt 6 is started and warm-up processing is performed (ST1).

  In the warm-up process, the continuous belt 6 is driven based on the preset acceleration state and time as described above.

  The continuation time of the warm-up process is monitored (ST2), and when it continues for a predetermined time, the steady motion process is executed (ST3).

  In step ST2, the operating state of the first mode switch 5D is monitored in a state where the predetermined time has not been reached (ST4). If operated, the speed at that time is detected, and the steady motion is based on the speed. Switch to the state (ST5).

  In the steady motion process shown in step ST3, as described above, a predetermined speed and a predetermined time are set as one cycle, or a speed and a predetermined time at the time when the first mode switch 5D is operated are set as one cycle. Continued processing is performed. Although not shown, when in the steady motion state, the input state from each of the acceleration / deceleration switches is monitored and switched to the selected speed.

The duration of the steady motion process shown in step ST3 is monitored (ST6), and when the predetermined time is reached, a cool-down process is executed (ST7).
In step ST6, the operation state of the second mode switch 5E is monitored in a state where the predetermined time has not been reached (ST8). If operated, the process proceeds to the cool-down process at that time.

On the other hand, the hydration process is performed when the passage of a predetermined time is detected in the course of the warm-up process, the steady motion process, and the cool-down process.
FIG. 6 shows the contents of the hydration process. In FIG. 6, the duration of each process is monitored to determine the hydration timing (ST9). When it is the hydration timing, an alarm process is performed, and the water catching ball display portion indicated by reference numeral 5P in FIG. The time is maintained (ST11).

  As a result, it is possible to prevent the posture at the time of water replenishment from becoming unstable because the speed of the continuous belt 6 becomes slower than before.

The deceleration time is monitored (ST12), and when the predetermined time is reached, the speed of the continuous belt 6 is returned to the original state (ST12). FIG. 5 shows the hydration process during the cool-down process incorporated in the flowchart.
In the hydration process shown in FIG. 6, when the release switch indicated by 5Q in FIG. 2 is operated, the deceleration process is stopped and the original speed is maintained.

  In this embodiment, the treadmill is the target of the aerobic exercise device, but the present invention is not limited to this, and it is also possible to target the ergometer (aero bike).
