“Respiratory muscle work limits high-intensity exercise tolerance in healthy human beings… In an occupational setting, heavy loads are routinely carried upon the trunk in the form of body armour, backpacks, and/or compressed air cylinders by military, emergency service, and mountain rescue personnel. This personal and respiratory protective equipment impairs respiratory muscle function and increases respiratory muscle work.”

Conclusion:

“An argument is presented that the unique respiratory challenges encountered in some occupational settings require further research, since these may affect the operational effectiveness and the health and safety of personnel working in physically demanding occupations.”
