Forty male volunteers were injected with bipolar fine‐wire electrodes into the tibialis anterior muscle and trained to isolate and cunt nil a single motor unit. A light panel indicated trial onsets and correct and incorrect responses. Subjects were randomly assigned to the isolation or non‐isolation condition for both sessions. Isolation condition was produced In an air‐fluidized. ceramic‐bead bed in a light attenuating chamber. A relearning session followed the initial session after a two week interim rest. The hypodynamic effects of sensory isolation increased the speed of learning to isolate and control an SMU. The results. suggested that subjects were better able to attend to the relatively weak proprioceptive information provided by the SMU through the reduction of the amount and/or variety of competing stimuli.
