Oxygen Consumption during Underwater Fin Swimming Wearing Dry Suits.

摘要

Oxygen consumption (VO2) during underwater fin swimming was measured with divers wearing dry suits in near-freezing water. During the last 30 min of a 40 min swim, VO2 was measured in eight U.S. Navy divers swimming in a cold water (2 deg C) flume. Each diver swam seven times, evaluating seven pairs of fins determined to have a large enough foot pocket to be used with dry suits with thick insulation. Weight distribution, volume of dry suit gas, and dry suit diving experience were all controlled. Swimming depth was 3 meters (9.8 ft) in a large area of constant flow in the cold water flume. VO2 consumption was calculated from loss of O2 bottle pressure, measured on-line and corrected for depth and temperature, to units of ml/min, standard temperature, pressure, dry (STPD).
