Effects of exercise on Pavlovian fear conditioning.

Exercise promotes multiple changes in hippocampal morphology and should, as a result, alter behavioral function. The present experiment investigated the effect of exercise on learning using contextual and auditory Pavlovian fear conditioning. Rats remained inactive or voluntarily exercised (VX) for 30 days, after which they received auditory-cued fear conditioning. Twenty-four hours later, rats were tested for learning of the contextual and auditory conditional responses. No differences in freezing behavior to the discrete auditory cue were observed during the training or testing sessions. However, VX rats did freeze significantly more compared to controls when tested in the training context 24 hr after exposure to shock. The enhancement of contextual fear conditioning provides further evidence that exercise alters hippocampal function and learning.
