Abstract
An in vivo buckle transducer technique was applied to study the reflex contribution to ATF enhancement during passive dorsiflexion stretches . Single stretches led to a linear ATF increase in the absence of an E MG reflex response, whereas clear ATF enhancement over the passive com ponent occurred 13-15 ms after the onset of EMG responses. To quantify the reflexly induced increase in ATF, the stretched position was main tained. The mean reflex effect was two to four times greater than the passive stretch effect.
