[Effect of exclusion of neural regulation on the contractile function of the myocardium of animals adapted to physical exertion].
The results of experiments conducted with the nervous regulation of the heart intact indicate that body adaptation to physical exercises results in an increased capacity of the cardiac mechanisms responsible for the regulation of both the force of the contractions, and the rate of adapted animals, revealed when the neuroregulation was switched off, in contrast to those of non-adapted animals, indicate the enhancement of the autoregulation mechanism of the heart muscle under the effect of physical training.
