Studies covered changes in external respiration system of young able-bodied males and females exposed to ambient air of negative temperature in natural climate of European North. Findings are that breathing cold air causes significant changes in static respiratory volumes and capacities, so vital lung capacity, inspiratory reserve volume and expiratory reserve volume were decreased, respiratory capacity was increased, respiratory level was decreased. Changes in the females appeared to be more than those in the males. |
