Investigation of an influence of body water balance and number of physiological reactions on electrical resistance of a human body
Resistance of a human body is one of the leading factors, which current magnitude, fl owing through a person, depends on and can cause electrical injury. In the article there are the results of two experiments, showing the change of a human body resistance after physical activity. In one experiment the person under test was doing hard physical activities without drinking water, in the other test - with water. In the graphs it is shown the change of a human body resistance in the setting of a persons tissues dehydration and a number of other body physiological reactions. The authors assume that the change of a human body resistance during the physical activity depends on a body water balance. Thus, during a shortterm physical activity a human body resistance goes down because of increase of circulation time, tubules volume and body liquid redistribution; but after a long-term physical activity there is desiccation in a body, which leads to body resistance increase. Thus, it is shown the importance of such a parameter as body water balance during testing on measuring a human body electrical resistance.
