[Effect of nasal respiration on the electrical activity of skeletal musculature].

Spontaneous electrical activity of human gastrocnemius and deltoid muscles was studied after physical overloading under the conditions of nasal or oral respiration. In nasal respiration, the electrical activity was enhansed as compared with oral respiration: stimulation of the nasal cavity receptors with air current seems to improve the respiratory center work and to produce optimal conditions for a wider irradiation of excitatory impulses from the respiratory center to the nerve-skeletal apparatus regulating the motor activity of the body.
