[Effects of hypokinesia on cardiac activity in rats with high and low spontaneous motor activity].
Hypokinesia effects on cardiac contractivity and vegetative regulation were studied in rats with high and low spontaneous motor activity. It was shown that hypokinesia promotes depression of the stroke volume and decrease of sympathetic nervous activity in rats with low motor activity. At the same time, in rats with high motor activity these parameters were not significantly affected by hypokinesia. The conclusion is made about a relationship between resistance to hypokinesia and spontaneous motor activity.
