Abstract:
1. A modulating device ( 300 ′)( 300 ) for a gymnastic machine ( 1 ) comprising a frame ( 10 ) supporting a load group ( 20 ) that can be actuated cyclically for power exchange with a user during training; at least one first lever ( 24 ) carried by said frame ( 10 ) in a rotatable manner around a first pivot axis (A 1 ) and provided with a respective user interface ( 243 ) cyclically movable along a closed trajectory (T) longitudinally delimited by a first position (PMA) and by a second position (PMP) of inverting the motion of said interface ( 243 ); a transmission group ( 30 ′)( 30 ) being provided to connect mechanically each said first lever ( 24 ) to said load group ( 20 ); characterised by comprising operating means ( 32 ′)( 302 ) designed to modulate an acceleration of each said user interface ( 243 ) along said trajectory (T) to maintain said acceleration, in use, near to physiological values; wherein said operating means ( wherein said first rotating member ( wherein said first rotating member (
