Abstract

A method of measuring expended energy of a moving body, comprising the steps: i) providing at least one first sensor for measuring position data and/or orientation data and/or dynamic data of a first part of the moving body; ii) providing at least one second sensor for measuring relative position data and/or orientation data and/or dynamic data of a second part of the moving body, wherein the second part is moveable relative to the first part and connected to the first part by a first resistive deformable element; iii) using the at least one first sensor to make a first measurement of the position and/or orientation and/or dynamics of the first part over a period of time and subsequently calculating a global expended energy of the first part relative to a reference frame from the first measurement; iv) using the at least one second sensor to make a second measurement of the position and/or orientation and/or dynamics of the second part over said period of time and subsequently calculating a relative expended energy of the second part relative to the first part from the first and second measurements, wherein the calculation includes the energy required to deform the first resistive deformable element when moving the second part relative to the first part; and v) calculating the total expended energy of the moving body by summing the global expended energy with the relative expended energy; wherein the at least one first sensor comprises a global positioning system (GPS) sensor and/or an inertial measurement unit and/or a first plurality of reference indicia measurable by an image capture device; and the at least one second sensor comprises an inertial measurement unit and/or a second plurality of reference indicia measurable by an image capture device.
