1. Muscular exercise apparatus, for maintaining a maximum speed independent of an exercise force applied by an exercising person, comprising:

  • exercising means for engagement by said exercising person to apply said exercise force;

    a mounting frame;

    a brake stator, fixedly supported by the mounting frame;

    a brake rotor facing, juxtaposed and engageable with the brake stator;

    telescoping means having a pair of nested coaxial members, said coaxial members being threadably engaged to expand and contract axially in response to relative coaxial rotation of said coaxial members, said telescoping means being coupled between said mounting frame and said brake rotor for reciprocating said brake rotor with respect to said brake stator in response to relative coaxial rotation of said members;

    a reference motor coupled to one of said pair of coaxial members, the other one of said coaxial members being coupled to said exercising means to be rotated thereby;

    whereby an effective difference between the rotational speeds produced at the telescoping means by the reference motor and the exercising means is translated into linear, axial motion of the brake rotor, controlling brake pressure.
