[Effect of various forms of physical exertion on selected types of sensory function].

The author reports changes in vibration and two-point discrimation sensitivity in groups of healthy young males after several days of intense physical effort and after one short-lasting intense exercise. The vibration sensitivity was a steady type of sensory function showing no significant changes after these workloads. The two-point discrimination sensitivity was, not infrequently, better after several days of effort in relation to preliminary state, and it was regarded as an evidence of adaptation to work. On the other hand, one sort-lasting exercise reduced significantly discrimination of two stimuli, especially on the lower extremities. This significant impairment of two-stimuli discrimination on the lower extremities in relation to the upper ones after intensive effort suggests easier exhaustion of pathways conveying sensation in the thoracic segment of the spinal cord. On the basis of these investigations the author thinks that aesthesiometric investigations carried out under strictly observed conditions may be useful for assessment of fatigue.
