Abstract

An apparatus for measuring the quantity of physical exercise in which the measurement of the quantity of physical exercise automatically ceases for intermissions of exercise, thereby providing an exact quantity of physical exercise.

Claims

1. An apparatus for measuring the quantity of physical exercise comprising:

exercise time measuring means for measuring a length of time for which the physical exercise continues;

movement detecting means responsive to movement of the body of a person taking the exercise for generating movement signals each representing the movement of the body;

exercise pace detecting means for measuring intervals between subsequent movement signals and detecting an exercise pace;

individual data storage means for storing at least the stride of the person;

judging means for making a judging as to whether movement signals exist or not;

arithmetic means for calculating the quantity of movement on the basis of the exercise time, the stride and the exercise pace; and

display means for displaying the quantity of movement thus calculated,

whereby the time measurement by said exercise time measuring means is controlled on the basis of the judgment made by said judging means.

2. An apparatus for measuring the quantity of physical exercise according to claim 1 wherein if further comprises sampling means for generating sampling signals at regular intervals, thereby permitting said judging means to make a judgment as to whether movement signals exist or not at regular intervals.

3. An apparatus for measuring the quantity of physical exercise according to claim 1 wherein said individual data storage means further includes means for storing data of one'"'"'s weight and data of one'"'"'s age.

4. An apparatus for measuring the quantity of physical exercise according to claim 1 wherein said arithmetic means is capable of calculating the quantity of physical exercise in calorie by multiplying the quantity of physical exercise by data of weight and data of age as adjustment coefficients.

5. An apparatus for measuring the quantity of physical exercise according to claim 1 wherein it further comprises pace judging means for making a judging as to whether said exercise pace is below a given reference value or not, and measured pace adjustment means for doubling the measured pace if the measured pace is below said given reference value.

6. An apparatus for measuring the quantity of physical exercise according to claim 1 wherein it further comprises arithmetic means for expressing the quantity of exercise in the range of aerobics in terms of point.

7. An apparatus for measuring the quantity of physical exercise according to claim 4 further comprises integrating means for integrating the quantity of exercise with respect to time.

8. An apparatus for measuring the quantity of physical exercise according to claim 2 wherein said sampling means if capable of generating sampling signals at intervals of two minutes.

9. An apparatus for measuring the quantity of physical exercise according to claim 6 wherein it further comprises integrating means for integrating the quantity of exercise with respect to time.
