Summary
Oculocardiac Aschner's reflex undergoes phasic changes during static muscular efforts. The main and the most stable and prolonged is the phase of decreased reflex strength (reduction of the inhibitory effect on the rhythm of the cardiac contraction), pointing to the prevalence of the inhibitory process in the higher portions of the central nervous system during static muscular efforts. This confirms the suggestion that the main role in the changes occurring in the activity of internal organs during static efforts belongs to reflex mechanisms.
