Graduated physical exercise with the moderate power (50% of PWC170) induces marked change in such cardiovascular system indices as stroke volume and cardiac output, heart rate in boys with the age of 11-16 years. The nature ...

Atropine induced various changes in the heart rate in intact rats of various ages. In sympathectomized animals, changes in heart rate variability were less pronounced. Atropine blocked the inhibition of cardiac activity ...

The purpose of the present research was to study motor agility and heart rate indices in athletes engaged in physical exercises differing by the character of performance. The research results of special agility physical ...

This paper deals with the features of changes in the indicators of cardiac pump function of rats and their regulation mechanisms during systematic muscle training organized at an earlier stage of their development, i.e., ...

© 2019 Ziyatdinova et al. The autonomic nervous system is involved in the regulation and formation of the heart rhythm. Most experimental studies about the influence of the autonomic nervous system on heart activity in ...

Changes in heart rate and stroke volume after successive blockade of cardiac adrenoand cholinoceptors were examined on rats of different age. It was established that irrespective of animal age the heart rate remained ...

For the first time, studies have been conducted to study the reaction of animal heart rate to various modes of motor activity after a traumatic brain injury. It was revealed that on the first day after modeling an open ...
