  • Title: [A study of arterial pressure, pulse rate and capnogram during exhaustive muscular work performed by healthy subjects while breathing air or 100% oxygen (author's transl)].
    Author: Quatrini U, Benigno A, Randazzo V.
    Journal: Lav Um; 1976 May; 28(3):73-81. PubMed ID: 1011913.
    Abstract:
    Eight untrained healthy young men were submitted to exhaustive physical exercise, performed on a bicycle ergometer while breathing either air or 100% oxygen, Arterial pressures, pulse rate and, in some instances, capnogram too were recorded during exercise and at the end of it. In the majority of subjects, 100% oxygen breathing was found to improve in some way work performance, in comparison with air breathing. However, the differences in the parameters examined appeared to be subjective and inconstant and to change according to work load levels.
