[Physical exercise and the quantitative characteristics of moisture- excreting function of the lungs]

Physical loading has been used as a test to study the regulation of moisture excretion in the act of breathing in 101 healthy students, 62 men with external risk factors, and in 73 patients with respiratory diseases (chronic bronchitis, acute pneumonia, bronchial asthma). The correlation of moisture excretion with the parameters of ventilation, age, sex, body weight of examinees proved that physical loading in the age-groups above 50 with excess body weight and with hyperventilation resulted in blocking effect on the volume of moisture loss during breathing. Thus, these endogenic factors determine the individual reaction in dynamics of moisture loss during physical loading and could be considered as risk factors in deteriorations of moisture excreting function of lungs.
