Contemporary Korean women divers wear wet suits during diving work to avoid the cold water stress. The present study was undertaken to evaluate the effect of wearing wet suits on the daily thermal balance of divers and on the duration of diving work. Rectal (TR) and skin temperatures and O2 consumption (VO2) were measured in four divers before and during diving work in summer (22.5 degrees C water) and winter (10 degrees C water). Subjects wore either wet suits (protected) or cotton suits (unprotected) for comparison. TR decreased 0.4 degrees C in summer and 0.6 degrees C in winter after 2 h of diving work in protected divers, while it decreased to 35 degrees C in 60 min in summer and in 30 min in winter in unprotected divers. Mean skin temperature of protected divers decreased to 31 degrees C in summer and 28 degrees C in winter, while that of unprotected divers decreased to 24 degrees C in summer and 13 degrees C in winter. VO2 toward the end of the diving work period increased by 80 (summer) and 140% (winter) in protected divers and by 160 (summer) and 250% (winter) in unprotected divers. From these values total thermal cost of diving work was estimated to be 260 and 370 kcal . day-1 in summer and winter, respectively.
当代韩国女性潜水员在潜水作业时会穿潜水服以避免冷水压力。本研究旨在评估穿着潜水服对潜水员每日热平衡以及潜水作业时长的影响。在夏季(水温22.5摄氏度)和冬季(水温10摄氏度),对四名潜水员在潜水作业前和作业期间测量了直肠温度(TR)、皮肤温度和耗氧量(VO2)。为作比较,受试者分别穿着潜水服(受保护组)或棉质服装(未受保护组)。在受保护的潜水员中,潜水作业2小时后,夏季直肠温度下降0.4摄氏度,冬季下降0.6摄氏度;而在未受保护的潜水员中,夏季60分钟内直肠温度降至35摄氏度,冬季30分钟内降至35摄氏度。受保护潜水员的平均皮肤温度在夏季降至31摄氏度,冬季降至28摄氏度;而未受保护潜水员的平均皮肤温度在夏季降至24摄氏度,冬季降至13摄氏度。在潜水作业末期,受保护潜水员的VO2夏季增加80%、冬季增加140%,未受保护潜水员的VO2夏季增加160%、冬季增加250%。根据这些数值,估计潜水作业的总热消耗在夏季和冬季分别为260千卡/天和370千卡/天。
