<p>A resistance training apparatus includes a linear electromagnetic resistance assembly comprising an elongate stator 22 and an armature 23 moveable along the stator, such that electromagnetic interaction between the armature and stator provides an opposing exercise force for resistance training when movement of the armature relative to the stator is effected by a user. The apparatus may be used in a passive mode in which eddy currents 27 generated within the armature provide an opposing resistive force against movement of the armature, or in an active mode in which electrical currents are fed to the armature to provide the resistive force. One or more regulators may be used to control the currents flowing in the armature, and thus the extent of the resistive force experienced by the user. The armature preferably comprises an electrically conductive tubular sleeve which travels coaxially along the length of the stator, and the stator preferably comprises a series of permanent magnets (see figure 2). Power generated by relative movement of the armature and stator may be stored, or used for supplying electrical equipment or local power distribution networks, and the amount of generated power may be communicated to the user.</p> |
