ABSTRACT:
An isokinetic multidirectional exerciser utilizes an articulated boom mounted to a supporting base for pivotal movement relative to the base. The articulated boom preferably uses two arms which are pivotally connected. Relative movement between the boom arms and the base is individually resisted by fluid devices operatively connected between the members that move relative to one another during use of the exerciser. Each fluid device includes a resistive closed fluid path that is adjustable to vary the range of resistance that will be encountered during such movement. Provision is made for independent adjustment of resistance in opposite directions of movement of the exerciser members. This is accomplished by use of opposed check valves having individual bypass paths and flow control valves.
