Abstract :
The dual-strategy hypothesis of motor control is extended to isometric contractions about the elbow. Subjects made isometric contractions (both pulses and steps) of different amplitudes and rates. The speed-sensitive strategy is used when the task requires the subject to explicitly regulate the rate at which torque is generated. In all other situations, the speed-insensitive strategy is used
