80名受试者均系海军潜艇学院学员,男性,年龄18～21岁,身体健康,无晕船史。受试者按潜水深度(8～10、18～20、28～30、38～40m)分为4组,每组20人,分别于受试前后30min内采肘静脉血检测。各实验日运动量与平时训练相近。4个潜水深度均在渤海湾某锚地实施。激素测定全部用放射免疫法。 结果:(1)下潜前后垂体激素的变化:GH在下潜后各深度均较下潜前显著升高(P<
80 subjects were all naval submarine college students, men, aged 18 to 21 years old, good health, no seasickness history. Subjects were divided into 4 groups according to the diving depth (8 ~ 10,18 ~ 20,28 ~ 30,38 ~ 40m), with 20 in each group. The elbow venous blood was collected within 30 minutes before and after the test. The amount of exercise on the experimental day and the usual training similar. Four diving depths are implemented in an anchor in the Bohai Bay. Hormone determination by radioimmunoassay. Results: (1) The changes of pituitary hormone before and after the dive: The depth of GH after the dive was significantly higher than that before the dive (P <
