The effects of controlled muscle tension on performance and learning of heart-rate control

• Thirty female subjects were divided in three groups and instructed in group I to increase their HRs with the aid of continuous feedback of performance, while they tensed their right forearm muscles 20% of maximal voluntary contraction. In the last session only feedback was used. Group II were trained with feedback only. Group III for the first two sessions tensed their muscles only, and in the last session trained HR increases with feedback only.Group I was superior in HR performance in the first two sessions. In the third session they deteriorated significantly and could not be distinguished from the other two groups. The results were interpreted in terms of relations between somatic and autonomic events and transfer between different states of somatic involvement during learning.Electrodermal activity and respiration were included as control variables.
