| 摘要： | Eight U.S. Navy divers were submerged in 7.2 C (45 degrees F) water for a maximum of two hours in three different conditions: no heating while wearing a semidry suit, heated in a semidry suit, and heated in a 7mm wet suit. A total of 35 W was delivered to each heating pad. Statistical analysis demonstrated that providing heating to the divers afforded no benefits in reducing the effects of cold water exposure on the skin temperature of the body extremities (fingers and toes) or in enhancing manual dexterity, grip strength, or cognitive performance when the effects of such heating were compared to those of the unheated condition. However, the participants reported that they would rather dive with the heating system than without it. / NOTE:Technical rept. Sep 2003-Mar 2005. |
