1. A system for analyzing motion of a user, comprising:
- a tri-axial accelerometer affixed to a user'"'"'s foot;
a processor coupled to the tri-axial accelerometer; and
a computer memory coupled to the processor, the computer memory comprising computer executable instructions that when executed by the processor cause the processor to perform the following;
a) collecting accelerometer data from the tri-axial accelerometer;
b) determining incline during stance phase based on the accelerometer data from the tri-axial accelerometer using an electronic processor;
c) determining stance phase based on the accelerometer data from the tri-axial accelerometer using the electronic processor; and
d) determining an energy expenditure of the individual based on the inclination of the shoe with respect to the ground over a period of time using the electronic processor.
