Abstract

Example embodiments may relate to a system, method, apparatus, and computer readable media configured for monitoring a user performing an athletic movement and/or exercise and generating a fatigue value. Fatigue values may be determined for different groups. In one embodiment, a first value is determined for a muscle fatigue value and a second value is determined for a respiratory value. In another embodiment, a first value may pertain to a first muscle group and a second value may pertain to a second muscle group. A fatigue index may be created from values obtained during an athletic movement and/or a workout session. In further embodiments, a cumulative fatigue index may be determined. A cumulative fatigue index may consider values obtained during several workout sessions. Further, data obtained outside of workout sessions may be considered in determinations relating to fatigue values and/or indices.

Claims

1. A computer-implemented method comprising:

providing first instructions to a user to perform an athletic movement comprising predefined criteria at a first location during a first time period;

detecting, with at least a first sensor, an item of apparel of the user performing the athletic movement corresponding to a position of a body part of the user at the first location;

constructing a form profile, wherein the form profile comprises a plurality of data points generated by the sensor during the athletic movement, wherein a selected data point, from the plurality of data points, comprises the location of the body part of the user in combination with a time stamp;

comparing the form profile against a first profile template for the athletic movement;

determining, based on the comparing, that the user'"'"'s performance comprises an improper form that may result in injury; and

adjusting, in response to the determining, the predefined criteria to decrease a difficulty of the athletic movement.

2. The method of claim 1, wherein the determining that the user'"'"'s performance comprises an improper form is based on a detection of the body part of the user outside of a compliance zone.

3. The method of claim 2, wherein the adjusting the predefined criteria is based on the body part of the user being outside of the compliance zone for a threshold amount of time.

4. The method of claim 1, wherein the plurality of data points are associated with intermittent times stamps over the first time period.

5. The method of claim 4, wherein two data points, selected from the plurality of data points, are separated by at least 1 hour.

6. The method of claim 4, wherein two data points, selected from the plurality of data points, are separated by at least 12 hours.

7. The method of claim 1, wherein the first sensor is worn by the user.

8. The method of claim 1, wherein the first sensor is remote from the user.

9. The method of claim 1, wherein the first sensor comprises an image capture device.

10. The method of claim 1, wherein the detecting the position of the body part of the user comprises detecting an item of apparel of the user performing the athletic movement.

11. The method of claim 1, further comprising:

estimating with a processor, based on the user'"'"'s performance, a muscle fatigue value.

12. The method of claim 11, wherein based upon a determination that the muscle fatigue value exceeded a threshold, determining second instructions to provide the user to promote muscle regeneration.

13. The method of claim 1, wherein the determining of the of the user'"'"'s performance of the predefined criteria further comprises:

upon detecting a first variance from a form profile threshold, transmitting first instructions to the user providing motivation to complete the criteria; and

further detecting the user'"'"'s performance of the predefined criteria.

14. A computer-implemented method comprising:

providing first instructions to a user to perform an athletic movement comprising predefined criteria at a first location during a first time period;

detecting, with at least a first sensor, a position of a body part of the user at the first location;

constructing a first form profile, wherein the form profile comprises a plurality of data points generated by the sensor during the athletic movement, wherein a selected data point, from the plurality of data points, comprises a location of the body part of the user in combination with a time stamp;

comparing the first form profile against a form profile template for the athletic movement;

determining, based on the comparing, that the user'"'"'s performance comprises an improper form that may result in injury; and

adjusting, in response to the determining, the predefined criteria to decrease a difficulty of the athletic movement.

further detecting the user'"'"'s performance of the predefined criteria during a second time period comprising;

constructing a second form profile of the user as a function of time during user'"'"'s performance of the athletic movement;

comparing the second form profile against a form profile template for the athletic movement, and

estimating with a processor a muscle fatigue value based upon, at least in part, the user'"'"'s performance at the first location during the first time period and the second time period.

15. The method of claim 14, wherein the determining that the user'"'"'s performance comprises an improper form is based on a detection of the body part of the user outside of a compliance zone.

16. The method of claim 15, wherein the adjusting the predefined criteria is based on the body part of the user being outside of the compliance zone for a threshold amount of time.

17. The method of claim 14, wherein the plurality of data points are associated with intermittent times stamps over the first time period.

18. A device configured to be worn on an appendage of a user comprising:

a processor;

a sensor; and

a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor perform at least;

detecting with at least the sensor, a position of a limb of the user;

constructing a form profile, wherein the form profile comprises a data point generated during the athletic movement, and wherein the data point comprises a location of a body part of the user in combination with a time stamp;

comparing the form profile against a form profile template for the athletic movement;

determining, based on the comparing, that the user'"'"'s performance comprises an improper form that may result in injury; and

adjusting, in response to the determining, a difficulty of the athletic movement.

19. The device of claim 18, wherein the determining that the user'"'"'s performance comprises an improper form is based on a detection of the body part of the user outside of a compliance zone.

20. The device of claim 19, wherein the adjusting the difficulty is based on the body part of the user being outside of the compliance zone for a threshold amount of time.
