The authors present data concerning influence of gas-masks with higher respiratory resistance on functional state of subjects performing physical and operator tasks. Finding are that only individuals with high general capacity for work (PWC170 over 3.0 W/kg of body weight) could perform tasks in heavy gas-masks, therefore only for them the specification of work and rest schedule is possible. Real flow rates for inspiration and expiration under physical load in gas-mask occurred exceeding the value (30 l/min) that is accepted in national standards and servers for calculating the individual respiratory protective means resistance to air flow.
