Steady alterations of motor activity in chick embryos were demonstrated under conditions of a controlled experiment, in production regimens of various directions. During controlled support by electrocutaneous stimulation of threshold amplitudes of the movements, the following characteristic time periods were distinguished: transitional, of steady alterations of motor activity with minimization of the amount of electrostimuli, and of the period of aftereffect. The conclusion is drawn about the united adaptive effect (minimization of biologically adverse influences) provided by the biorhythm of motor activity with directional potentiation of the activity of the components, which are not supported by adverse effects.
在可控实验条件下，在不同方向的生产方案中，已证明鸡胚运动活动的稳定变化。在通过电皮肤刺激运动阈值幅度进行可控支持期间，区分出以下特征时间段：运动活动稳定变化且电刺激量最小化的过渡阶段，以及后效应阶段。得出的结论是，运动活动的生物节律具有联合适应性效应（将生物不利影响最小化），同时对不受不利影响支持的各组成部分的活动进行定向增强。
