Abstract

Methods and apparatuses for athletic performance monitoring with body synchronization analysis are disclosed. In one example, a first sensor output associated with a movement of an user foot and a second sensor output associated with a movement of an user arm are received, the user arm on a body side opposite the user foot. The first sensor output and the second sensor output are analyzed to identify a degree of synchronization between the movement of a user foot and the movement of a user arm.

Claims

1. A method comprising:

monitoring a running speed with a global positioning system (GPS) unit while monitoring a movement of a first body part with a first sensor providing a first sensor output and monitoring a movement of a second body part with a second sensor providing a second sensor output;

monitoring a run distance with the global positioning system (GPS) unit;

identifying a first undesirable movement of the first body part comprising utilizing both the first sensor output and the second sensor output, wherein the first undesirable movement of the first body part is of a first undesirable movement type;

identifying a second undesirable movement of the first body part having a second undesirable movement type different from the first undesirable movement type, the second undesirable movement comprising a rotational component;

outputting an indication of the running speed and the run distance at a device user interface; and

outputting an indication of the first undesirable movement of the first body part or an indication of the second undesirable movement of the first body part at the device user interface, the first undesirable movement of the first body part determined utilizing both the first sensor output and the second sensor output.

2. The method of claim 1, wherein identifying the second undesirable movement of the first body part comprises utilizing the running speed monitored with the GPS unit.

3. The method of claim 1, wherein identifying the first undesirable movement of the first body part comprises utilizing the running speed monitored with the GPS unit.

4. The method of claim 1, further comprising identifying an undesirable motion of the second body part from the second sensor output.

5. The method of claim 4, wherein identifying the undesirable motion of the second body part from the second sensor output comprises utilizing the running speed monitored with the GPS unit.

6. The method of claim 1, wherein the indication of the first undesirable movement of the first body part at the device user interface is an alert indication.

7. A system for analyzing athletic activity comprising:

a first sensor configured to generate a first sensor output signal responsive to a movement of a first body part;

a second sensor configured to generate a second sensor output signal responsive to a movement of a second body part;

a global positioning system unit configured to monitor a user speed or pace;

a user interface;

a processor; and

a memory storing an application program executable by the processor configured to identify a first undesirable movement of the first body part comprising utilizing both the first sensor output signal and the second sensor output signal while simultaneously monitoring the user speed or pace with the global positioning system unit, the movement of the first body part with the first sensor, and the movement of the second body part with the second sensor, wherein the first undesirable movement of the first body part is of a first undesirable movement type, the application program further configured to identify a second undesirable movement of the first body part having a second undesirable movement type different from the first undesirable movement type, the second undesirable movement comprising a rotational component, and wherein the application program is further configured to output an indication of the first undesirable movement of the first body part at the user interface.

8. The system of claim 7, wherein the application program is further configured to utilize the user speed or pace monitored with the global positioning system unit to identify the second undesirable movement of the first body part.

12. The system of claim 7, wherein the indication of the first undesirable movement of the first body part at the user interface is an alert indication.

13. One or more non-transitory computer-readable storage media having computer-executable instructions stored thereon which, when executed by one or more computers, cause the one more computers to perform operations comprising:
