title: Morphofunctional characteristics of spinal cord neurons after single integrative motor loads.
abstract: Motor and intermediate neurons in the fourth lumbar segment of the spinal cord were studied in 38 mongrel male dogs with the aim of detecting adaptive morphological changes in spinal cord elements after exposure to dosed physical loads (running on the treadmill for periods of 7-35 min). These experiments showed that single integrative physical loads facilitate significant increases in the numbers of functionally active cells. Morphological changes to motor neurons were more marked than those of associative nerve cells.
