Apparatus, systems, and methods for gathering and processing biometric and biomechanical data
Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

the first body portion is selected from the group consisting of a head, an ankle, a waist, or a lower leg;
the second body portion is selected from the group consisting of a shoulder, hip, upper leg or upper arm; and
the third body portion is selected from the group consisting of an arm, hand or foot.
4. A sports movement data apparatus comprising:
a single first sensor having a first sampling rate that is associated with a first body portion of a user, the single first sensor being configured for sensing movement of the first body portion at the first sampling rate during activity that involves movement of the first body portion within a first range of speeds;
a single second sensor having a second sampling rate that is associated with a second body portion of the user, the single second sensor being configured for sensing movement of the second body portion at the second sampling rate during activity that involves movement of the second body portion within a second range of speeds, wherein an average of the second range of speeds is less than an average of the first range of speeds;
a control unit configured to receive data from at least the first and second sensors; and
a processor configured to communicate with the control unit and obtain information related to at least one of the first and second sensors;
wherein the single first sensor is selectively configured to sense body movement at the first sampling rate range, the single second sensor is selectively configured to sense body movement at the second sampling rate range, and the first sampling rate range is faster than the second sampling rate range such that the movement of the first body portion is recorded with more data samples than the movement of the second body portion during a same time period.
5. The system of claim 4 , wherein the first sampling rate range that is associated with a first body portion of a user is a selected sampling rate range at which the processor receives first-sensor data, and the second sampling rate range that is associated with a second body portion of the user is a selected sampling rate range at which the processor receives second-sensor data.
6. The system of claim 4 , wherein the single first sensor is configured for sensing movement of the first body portion within the first sampling rate range during a first time period, and the single second sensor is configured for sensing movement of the second body portion at a second time period, wherein the single first sensor is selectively programmed for sensing movement at the first sampling rate range.
7. The system of claim 6 , wherein the first time period overlaps with the second time period.
8. The system of claim 6 , wherein the single first sensor and the single second sensor are configured for sensing movement at a first sampling rate during the first time period, and the single first sensor and the single second sensor are configured for sensing movement at a second sampling rate during the second time period.
9. The system of claim 4 , wherein the first body portion is an appendage of a user.
