ABSTRACT:
The exercise apparatus includes, a motor-reduction gear unit (10, 11) controlling an input shaft (20), and mounted on a frame (1). A drum (50) receives a cable (5) at the end of which there is placed a detector (155) and then a handle (56). Between the shaft (20) and the drum (50) there are mounted in parallel firstly a freewheel transmission (36) and, secondly an electromagnetic powder clutch (35). Various pre-adjusted control values for exciting the clutch (35) enable accurate adjustment of the apparatus, in particular for exercises of the "servo-controlled work", "static work", or "direct work" types, to be accompanied by "rest" phases.
