The weight may be measured during exercise by providing a strain gauge or the like on the aerobic exercise equipment.

FIG. 6 is an enlarged view of a main part in which a part of the handlebar H on which the electrodes are mounted is enlarged.
The handlebar H is provided with left and right grips HL and HR in the middle of a rod-shaped insulator, and the power supply side electrodes H1 and H1 and the detection side electrodes H2 and H2 are respectively bonded to form a four-terminal electrode. An interval is provided between the power supply side electrodes H1, H1 and the detection side electrodes H2, H2 so as not to contact each other.
The location of these electrodes is not limited to the handlebar H, but may be other locations such as the outer periphery of the case of the color liquid crystal panel C.

FIG. 7 shows a block diagram of a measuring circuit of the human body impedance measuring means 11.
The measurement circuit supplies a 50 kHz sine wave AC voltage generated by the oscillator 23 to the power supply electrodes H1 and H1 via the drive circuit 24, the transformer T1, and the changeover switch 25A.

When the left and right grips HL, HR of the handlebar H are gripped with both hands, an AC voltage is generated between the detection-side electrodes H2, H2.
The AC voltage generated at the detection-side electrodes H2, H2 is converted into a DC voltage via a changeover switch 33AS, a transformer T2, a bandpass filter 26, a rectifier circuit 27, and an amplifier 28, and after waveform shaping, level adjustment, and offset adjustment, A It is input to the CPU 31 via the / D converter 29 and the I / O interface 30. 32 is a memory.

Before measuring the human body impedance, the output characteristics of the detection-side circuit are calibrated in advance in order to correct a measurement error due to a change over time or a temperature characteristic of an element constituting the measurement circuit.
That is, the relationship between the human body impedance Z, which is two variables, and the AC voltage V detected by the detection-side circuit is applied to the regression line Z = kV + C0.
Then, the same predetermined AC voltage as when measuring the human body impedance Z is applied to both ends of the two resistors R1 and R2 whose resistance values are known, and the AC voltage V generated across both ends of the resistors R1 and R2 is detected. The proportional constant k and the fixed constant C0 of the regression line are obtained.

For this reason, a control signal is output from the CPU 31 to switch the changeover switch 33AS via the I / O interface 30, the changeover unit 33, and the changeover control circuit 33A, and to switch between the secondary side of the transformer T1 and the primary side of the transformer T2. The two resistors R1 and R2 are connected so as to be switchable.
Next, a control signal is output from the CPU 31 to switch the changeover switch 33BS via the I / O interface 30, the changeover unit 33, and the changeover control circuit 33B, thereby changing the measurement target to the resistor R1 or the resistor R2.

また、体脂肪率算出手段１３が計算する体脂肪率の計算方法を数式２に示す。

Equation 1 shows a calculation method of the human body impedance calculated by the human body impedance measuring means 11.

Formula 2 shows the calculation method of the body fat percentage calculated by the body fat percentage calculation means 13.

FIG. 8 shows a body type classification diagram in which the body type determination means 14 evaluates the balance between the weight and the body fat percentage and displays the result on the color liquid crystal panel C.
This body type classification diagram creates a matrix that composes the height and width by weight and body fat percentage, divides weight and body fat percentage into three ranges of healthy range, higher and lower, respectively, and divides the whole into nine classifications .
The healthy range of body weight is ideal weight × 0.9 to ideal body weight × 1.1, and the healthy range of body fat percentage is 10 to 20% for women and 8 to 18% for men.
The nine categories are defined as super sportsman type, sportsman type, obesity type, sportsman ideal type, healthy ideal type, super fat type, super thin type, thin type, excess fat type, and further subdivided in the cross direction. Are classified into 29 body types.
Here, ideal weight = (height−100) × 0.9 × 0.91 (the unit of weight is Kg, and the unit of height is cm, respectively).
Then, as shown in FIG. 9, the brightness of the region of the corresponding body type section of the color liquid crystal panel C is changed or blinked in order to indicate which body type section the current body type belongs to.

Exercise ability estimating means 15 estimates exercise ability, which is a premise for setting exercise intensity according to physical strength, in order to perform exercise safely and maximize exercise effects.
Exercise ability is generally estimated based on the maximum oxygen uptake, but here, exercise ability is estimated using lean tissue, such as muscle and bone, excluding body fat from body weight as a performance barometer.
In addition, since the exercise intensity for efficiently burning body fat is preferably about 60 to 90% of the maximum heart rate at the level of the heart rate, the maximum heart rate is 220-age. Add to your ability assessment. Gender is also included in the evaluation.
The target body type setting means 16 selects a target body type from nine types and 29 types of body types displayed on the body type classification diagram via the touch-type color liquid crystal panel C.
When the body type is selected, the target body type setting means 16 changes the brightness of that area or makes it blink, as shown in FIG.
The target body type can be selected according to preference, but if it is not selected within a certain period of time, the body type category of the ideal health type located at the center of the body type classification chart is automatically set.

The exercise frequency setting means 17 displays, for example, a period such as three months, a half year, and one year, and a frequency such as once a week, three times a week, and daily on a menu, and selects a period and a frequency from the menu. Set the number of exercises.
If the period and frequency are not selected within the determined input time, an appropriate period and frequency are automatically selected according to the difference between the target body type and the current body type, and the number of exercises is automatically set.

運動強度は、１４段階のレベルの中から、運動能力推計手段１４が推計した運動能力に応じたレベルがメニューに表示され、その中から選択する。
レベルが選択されない場合は、標準のレベルが自動設定される。 The required exercise amount calculating means 18 calculates the required amount of exercise for each number of exercises by comparing the target body shape with the current body shape.
In general, the amount of exercise can be expressed as the product of exercise intensity and time as follows.
Exercise amount (kcal) = exercise intensity (kcal / min) x exercise time (min)
Therefore, in order to increase the amount of exercise, it is necessary to increase exercise intensity or extend exercise time.
The required amount of exercise is determined by first obtaining a body fat mass to be reduced from the difference between the target body type and the current body type set for each number of exercises.
Since 1 kg of body fat is equivalent to approximately 7000 kcal, the amount of calories required to consume this amount of body fat is defined as the required amount of exercise.
The amount of calories per hour consumed by the exercise is determined by the formula of Equation 3 based on the intensity efficiency and the basal metabolic rate for each level.

As the exercise intensity, a level corresponding to the exercise ability estimated by the exercise ability estimating means 14 is displayed on a menu from among 14 levels, and is selected from the menu.
If no level is selected, a standard level is automatically set.

Once the level is set manually or automatically, the amount of exercise needed to consume the calorie-converted body fat previously determined is divided by the amount of calories per hour consumed by exercise, thereby Find exercise time.
Exercise time is set to 12 minutes or more, which is said to be the minimum required for body fat to start burning.

The exercise amount correcting means 19 obtains the amount of body fat to be reduced from the difference between the target body type and the current body type for each number of exercises, and newly calculates the calorie amount necessary for consuming the body fat amount as the necessary exercise amount. Then, the new momentum is sent to the required momentum calculating means 18 as a corrected momentum, and the required momentum is corrected.
In this way, through the operation panel, we present the exercise program necessary to achieve the target body type, such as how much exercise, how often, and how long, and according to the progress of the exercise If the exercise program is modified in such a manner, there is an advantage that the trouble of assembling the exercise program every time of exercise is eliminated, and the required exercise can be efficiently concentrated.

Next, the exercise program determining means 21 uses the exercise equipment for a certain amount of time in one exercise based on the required amount of exercise calculated by the means 18 and the set number of exercises set by the means 17, and determines the heart rate at that time. If the load is such that the number becomes enough, the required exercise amount can be digested, and an exercise program that determines the target heart rate and the use time of the exercise equipment is determined from the result.
The load changing means 22 compares the heart rate measured by the heart rate measuring means 20 with the target heart rate, and the gradient of the running belt B, the frictional resistance of the pedal P, the weight, Modify and adjust the load on the aerobic exercise equipment, such as braking torque.
As a result, the actual heart rate is kept in the heart rate zone of the exercise intensity set by the necessary exercise amount calculation means 18.

As described above, aerobic exercise equipment includes an indirect type in which the load is adjusted by the heart rate and a direct type in which the load is set independently of the heart rate.
In the case of the direct format, calculate how long you can use the exercise equipment and how much value you can use to exercise the required amount of exercise in one exercise. And an exercise program that determines the use time of exercise equipment. FIG. 5 illustrates both direct and indirect formats.
