Abstract

A method of monitoring human body movement includes measuring the motion of movable body parts using one or more measurement devices applied to the movable body parts during activity of the human body. A movement economy profile of the human body movement is calculated using the data from the measurement devices, where the movement economy includes determining movement relative to speed of the human body.

Claims

1. A method of monitoring human body activity comprising:

measuring the motion of movable body parts using one or more measurement devices applied to the movable body parts during activity of the human body; and

determining a movement economy profile of the human body movement using the data from the measurement devices, where the movement economy includes determining movement relative to speed of the human body.

2. The method of claim 1 in which the measurement device is one or more of accelerometers, gyroscopes, and GPS.

3. The method of claim 1 including comparing the movement economy profile information with a database containing data pertaining to movement economy profile information of other subjects.

4. The method of claim 3 including modifying the movement of the human body in response to the movement economy profile information.

5. The method of claim 1 in which the measurement devices are accelerometers that are arranged to measure acceleration in three axes:

anterior/posterior, vertical, and medial/lateral.

6. The method of claim 1 including treating the movement economy profile information according to one or more of the following:

transmitting the movement economy profile information to a web-based device, storing the movement economy profile information in a data storage device, displaying the movement economy profile information, comparing the movement economy profile information with a database containing data pertaining to movement economy profile information of other subjects, and printing the movement economy profile information.

7. The method of claim 6 including modifying the movement of the human body in response to the movement economy profile information.

8. The method of claim 6 in which the measurement devices are accelerometers that are arranged to measure acceleration in three axes:

anterior/posterior, vertical, and medial/lateral.

9. The method of claim 1 in which the gathering of the data from the accelerometers during movement of the human body occurs when the human body is moving in space and not on a stationary exercise machine.

10. A method of monitoring human body activity comprising:

measuring the motion of movable body parts using one or more measurement devices applied to the movable body parts during activity of the human body, where the measurement devices are arranged to measure acceleration in three axes; and

calculating the ratio of the measured movement along of one of the axes to the resultant movement along all three of the axes.

11. The method of claim 10 in which the three axes represent the anterior/posterior, vertical, and medial/lateral directions.

12. The method of claim 10 including comparing the ratio with a database containing data pertaining to movement ratio information of other subjects.

13. The method of claim 10 including modifying the movement of the human body in response to the ratio information.

14. A method of monitoring human body activity comprising:

measuring the motion of movable body parts using one or more measurement devices applied to the movable body parts during activity of the human body; and

determining the control entropy of the movement of the human body.

15. The method of claim 14 including comparing the control entropy with a database containing control entropy information of other exercise subjects.

16. A method of claim 14 where the motion occurs over a period of time and the measurement is made at multiple times during the period of time, and further including calculating the control entropy of the movement of the human body over the period of time, and determining when a state of fatigue for the human body is reached based on the calculated control entropy.

17. The method of claim 16 including ceasing the human body activity when the control entropy changes.

18. The method of claim 14 including modifying the movement of the human body in response to the control entropy information.

19. The method of claim 14 including determining physical constraints on the human body during the human body activity using the control entropy information.

20. The method of claim 14 in which the measurement devices are accelerometers that are arranged to measure acceleration in three axes:

anterior/posterior, vertical, and medial/lateral.
