Strength calibration

Abstract

A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement. The resistance force required to effect the first isokinetic seed movement is associated with a force-velocity profile. It is determined whether a sufficient number of isokinetic seed movements have been performed by the user. In response to a determination that the sufficient number of isokinetic seed movements have been performed by the user, a strength determination of the user is made based on the isokinetic seed movements performed by the user.
