Abstract

A method for performing human isometric exercise includes the steps of sensing an applied force, providing a signal representing the applied force, receiving the signal and comparing the applied force to a preselected force, and providing the result of the comparison to a user in real time. The result of the comparison may be provided in an alphanumeric or other visible display, or by auditory means. The time that force is applied may be compared to a preselected time period, and a message provided to a user to rest when the preselected time period has been reached. The number of repetitions of the application of force during a session may be compared to a preselected number of repetitions, and an indication of session completion provided to a user when the number of completed repetitions equals the preselected number. A device for use in isometric exercise includes a device for sensing an applied force and providing an output signal representing the applied force, electronics for receiving the signal and comparing the applied force to a preselected force, and providing the result of the comparison to a user.

Claims

1. An apparatus for use in isometric exercise, comprising means for sensing an applied force and for providing a signal representing the applied force, said sensing means being contained in a cuff adapted to mount on a limb of a user, and a hand held unit comprising means for receiving the signal, comparing the signal to a preselected force range, and providing the result of the comparison to a user in real time.

3. The apparatus of claim 1, wherein said means for sensing comprises first and second sensors located in said cuff and adapted to be positioned on opposite sides of a limb of a user.

4. The apparatus of claim 3, wherein each of said first and second sensors comprise capacitive force sensors.

5. The apparatus of claim 4, wherein each of said capacitive force sensors comprise a dielectric of open cell foam polyurethane.

2. An apparatus for use in isometric exercise, comprising means for sensing an applied force and for providing a signal representing the applied force, said sensing means being contained in a cuff adapted to mount on a limb of a user, and a hand held unit comprising means for receiving the signal, comparing the signal to a preselected force value, and providing the result of the comparison to a user in real time, wherein said force sensing means comprises a capacitive sensor.

6. An apparatus for use in isometric exercise, comprising means for sensing an applied force and for providing a signal representing the applied force, said sensing means being contained in a cuff adapted to mount on a limb of a user, and a hand held unit comprising means for receiving the signal, comparing the signal to a preselected force value, and providing the result of the comparison to a user in real time, wherein said handheld unit comprises setup means for receiving the preselected force, a selected exercise duration of time, and a number of repetitions.

7. An apparatus for use in isometric exercise, comprising means for sensing an applied force and for providing a signal representing the applied force, said sensing means being contained in a cuff adapted to mount on a limb of a user, and a hand held unit comprising means for receiving the signal, comparing the signal to a preselected force value, and providing the result of the comparison to a user in real time, wherein said handheld unit further comprises means for prompting a user to apply force for a selected exercise duration of time, prompting the user to rest for a selected rest duration commencing at the end of the selected duration, prompting the user to resume application of force at the end of the selected rest duration until the expiration of the selected exercise duration.

8. An apparatus for use in isometric exercise, comprising means for sensing an applied force and for providing a signal representing the applied force, said sensing means being contained in a cuff adapted to mount on a limb of a user, and a hand held unit comprising means for receiving the signal, comparing the signal to a preselected force value, and providing the result of the comparison to a user in real time, wherein said handheld unit further comprises means for monitoring a number of completed repetitions of an exercise, comparing the monitored number to a preselected number of repetitions, and notifying the user to change positions when the monitored number of completed repetitions is equal to the preselected number.

9. An apparatus for use in isometric exercise, comprising means for sensing an applied force and for providing a signal representing the applied force, said sensing means being contained in a cuff adapted to mount on a limb of a user, and a hand held unit comprising means for receiving the signal, comparing the signal to a preselected force value, and providing the result of the comparison to a user in real time, wherein said means for providing a result of the comparison means for providing a low force indication if an applied force is less than a preselected force range, providing a correct force indication if an applied force is within the preselected force range, and providing a high force indication if an applied force is in excess of the preselected force range.

10. An apparatus for use in isometric exercise, comprising means for sensing an applied force and for providing a signal representing the applied force, said sensing means being contained in a cuff adapted to mount on a limb of a user, and a hand held unit comprising means for receiving the signal, comparing the signal to a preselected force value, and providing the result of the comparison to a user in real time, further comprising means for calculating a target force value based on predetermined parameters and a detected maximum force value.
