title: [Morpho-functional characteristics of the spinal cord neurons after one-time integrating motor activity].
abstract: To investigate the adaptive morphological changes of cellular elements of the spinal cord following the dosed application of physical loads (running in treadmill for 7-35 min), the motor neurons and interneurons of i.v. lumbar spinal cord segment were studied in 38 mongrel male dogs. It was shown that single integrating physical loads contributed to significant increase in the number of functionally active neurons. It is noted that the morphological changes are more pronounced in the motor neurons as compared to interneurons.
