Abstract:

A small team of civilian scientific and naval operational personnel conducted a field-lab oratory research project on several physiolog ical problems in swimming with self contained underwater breathing apparatuses SCUBA. Among other findings, it was noted that the average for underwater swimming with SCUBA in the open sea is about 1.1 mph with an average respiratory minute volume of 28 liters while breathing com pressed air that during exercise, the respira tory minute volume was significantly smaller while breathing oxygen than while breathing air and that ventilation during exercise while breathing air was much smaller at greater depths than predicted theoretically. For protection against cold water, the group demonstrated quantitatively, the validity of the principle of using a wet underwater swim-suit made of unicellular foam rubber, in which no attempt is made to prevent water entry but rather only to restrict its free flow over the body surface.
