Abstract

An exercise device conveniently measures, monitors, and reports electromyograph (EMG) information to the user, for use in effectively strengthening selected muscles. The exercise device includes a sensor circuit responsive to electrical activity in tensioning muscles, and a control circuit responsive to an output signal produced by the sensor circuit. In a preferred embodiment the control circuit regulates an audio device, by attenuating the audio device output signal when the sensor output signal declines to below a preset threshold. Alternatively, the control circuit selectively activates an indication device, such as a vibrator, when the sensor output signal falls too low. The exercise device provides information as to muscle activity to the user in an entertaining fashion, and in a way that the user is not required to pay constant attention and refer to an output meter or other conventional display.

Claims

1. An abdominal tensioning device for promoting the tensioning of abdominal muscles of a user, the device comprising:

a) an indicator device for generating an indicator output signal;

b) an abdominal electrical activity monitor having at least one sensor disposed upon an outer surface thereof, said sensor being operative to detect electrical signals representative of a users level of abdominal contraction, the monitor being operative to generate a monitor output signal in response to the level of detected electrical signals, and to attenuate the monitor output signal when the level of detected electrical signals fall below a preset threshold, the monitor being formed to be disposable upon the user'"'"'s body adjacent the abdominal muscles of the user; and

c) a sensor sensitivity circuit for adjusting the preset threshold;

d) wherein the indicator device is operative to generate an indicator output signal when the detected electric signals fall below the preset threshold.

2. The device as recited in claim 1, further comprising a belt for securing the abdominal monitor about the user'"'"'s waist.

3. The device as recited in claim 1, wherein the indicator device comprises a vibrator for providing a vibration indication when the detected electrical activity falls below the preset threshold.

4. The device as recited in claim 3, wherein the sensor sensitivity circuit is operated to terminate vibration of the vibrator when the detected electrical signals increase above the preset threshold.

5. The device as recited in claim 1, wherein the indicator device comprises an audio device for providing a audio indication when the detected electrical signals falls below the preset threshold.

6. The device as recited in claim 5, wherein the sensor sensitivity circuit is operated to terminate the audio indication when the detected electrical signals increase above the preset threshold.

7. The device as recited in claim 1, wherein the indicator device comprises a visual display device for providing a visual indication when the detected electrical signals falls below the preset threshold.

8. The device as recited in claim 7, wherein the sensor sensitivity circuit is operated to terminate the visual indication when the detected electrical signals increase above the preset threshold.

9. The device as recited in claim 1, wherein the sensor is operative to continually detect electrical signals representative of the users ongoing level of abdominal contraction, and to generate a first output signal when the user'"'"'s abdominal muscles are relaxed and a second output signal when the user'"'"'s abdominal muscles are contracted.

10. The device as recited in claim 1, wherein the monitor is operative to progressively attenuate a monitor output signal in response to the level of contraction of the user'"'"'s abdominal muscles.

11. The device as recited in claim 9, wherein the monitor is contoured to conform to the user'"'"'s abdominal area.
