A biopsy device includes an outer cannula, an inner rod, a sheath operably associated with the outer cannula, a handle assembly removably attachable to the sheath, and a release member for releasably attaching the handle assembly to the sheath. In one embodiment, a locking element associated with the sheath comprises a pair of notches located on either side of the sheath, and a locking element associated with the handle assembly comprises a pair of slots in communication with an opening within the handle assembly. The release member comprises a rotatable collar located in a channel on the handle assembly. When the release member is rotated from a first position to a second position, a portion thereof protrudes through the slots into the notches on the sheath, thereby locking the sheath in place.

The method of claim 6 wherein the step of calculating data representing fat metabolization as a function of time during an exercise period comprises apportioning EE by extrapolation from 100% fat utilization at an RER of 0.7 to 0% at an RER of 1.0 where RER=VCO2/VO2. 8. The method of claim 7 and further including the step of plotting the data representing fat metabolization versus time to determine the point where said data exhibits a maximum acceleration towards zero.
