[Distortions of respiratory indices during muscle work in research procedures using masks].
Maskless telemetry of respiration (dynamic radiorheopneumography) developed by one of the authors was employed in observations over 66 persons during laboratory running and over 13 athletes in the course of routine training. It was shown that conventional research methods for pulmonary ventilation produce significant disturbances in the respiratory parameters: the respiratory rate diminishes, the respiratory volume increases. The disturbances are more pronounced in men, rising with increase in exercise intensity up to 20-30% and more. Transition from restrained to free respiration is accompanied by more remarkable changes in the respiratory parameters as compared to reverse transition.
