[The effect of cooling on the characteristics of a single skeletal muscle contraction in cold-adapted rats].
The time parameters and amplitude of the m. gastrocnemius twitch contractions were studied in control and in cold-adapted rats at optimal muscle temperature (29-30 degrees C) and after cooling the muscle to 24-25 degrees C. A decrease of the twitch contraction force and an increase of the time of the contraction to the maximum, occurred in cold-adapted rats. The cooling of muscle decreased the velocity of the twitch contraction in both groups of animals.
