Reaction Features of the Mature Rats’ Inotropic Heart Function Subjected to Different Modes of Motor Activity Under Adreno and M-Choline Stimulants

The research has been carried out for the first time to study the mice stroke volume (SV) response to the insertion of β, α1, α2-adrenergic and M-cholinergic stimulants.The largest increase in the SV response was revealed during animals muscle training with the insertion of β and α1-adrenergic stimulants and a simultaneous decrease in the SV response to the insertion of an M-cholinergic stimulant can be noted.A group of animals subjected to limited motor activity, i.e. hypokinesia was seen to have a decrease in the SV response to the insertion of β-, α1-, α2-adrenergic stimulants.Consequently, it can be argued that while animals subject to a regime of limited motor activity, the sympathetic regulatory influence remains at a low level.
