1. A system for collecting data related to user movements, comprising:

  • a plurality of wearable garments, wherein at least one garment comprises at least two sensors configured to collect data related to movement of a corresponding portion of the user in two or more dimensions, wherein a first sensor of the at least two sensors is configured for positioning on a first side of a joint of the user, and wherein a second sensor of the at least two sensors is configured for positioning on a second side of the joint opposite to the first side;

    one or more data storage devices storing instructions for processing the data; and

    one or more processors configured to execute the instructions to perform a method, including;

    for each sensor of the at least two sensors, receiving the data and analyzing the data to;

    calculate a global orientation of the corresponding portion of the user in two or more dimensions, and converting the global orientation of the corresponding portion of the user in two or more dimensions to a local orientation of the corresponding portion of the user in two or more dimensions within a user-specific coordinate system;

    calculate a horizontal impulse and a vertical impulse generated in the two or more dimensions within the user-specific coordinate system for the first and second sensors;

    based on the global orientation, the local orientation, the horizontal impulse, and the vertical impulse, generating feedback associated with the movement, wherein the feedback includes a joint force and a joint torque indicative of gait, body, or biomechanical issues;

    sending the feedback to a mobile device; and

    providing the feedback to the user via a display on the mobile device, wherein the feedback includes graphical or visual representations of received and analyzed performance and movement data for each individual sensor or a plurality of sensors such that the feedback includes representations of the user'"'"'s body in two or more dimensions with indicators to highlight a particular portion of the representation of the body representing a problematic gait, one or more body abnormalities, or other biomechanical issue for that portion, and wherein the feedback further includes one or more graphs displayed for a particular joint or portion of the body, with the one or more graphs displayed next to the particular joint or portion of the body.
