前苏联军人体育训练教范中规定军人必须接受屏气潜泳训练,冰距限为45m以内,但1989年以后竟随意延长为50m.作者通过人体试验证明,屏气潜泳泳距50m会造成人员发生急性氧饥饿,发现大脑缺氧,意识突然丧失和造成淹溺事故,因此认为合理泳距仍应限为45m以内.40名19～23岁健康受试者均分2组,分别在25m室内池(水温25～26℃)内参加45和50m两种距离屏气潜泳(水下1～1.5m).在入水前先进行过度换气(8～10次吸气和呼气),并在换气前后以及在潜泳结束后采集呼出气体,用德国Eger公司的Ergo Pneu-
Former Soviet Union sports training teaching model provides that soldiers must accept the breath-holding snorkeling training, ice limit within 45m, but was arbitrarily extended to 50m after 1989. The author’s body tests show that the breath-hold swimming distance of 50m will cause the occurrence of acute oxygen Hunger and found that the brain hypoxia, a sudden loss of consciousness and caused drowning accidents, so that the reasonable swimming distance should be limited to 45m or less.40 healthy subjects aged 19 to 23 were divided into two groups, respectively, 25m indoor pool (water temperature 25 ~ 26 ℃) to participate in two kinds of distance 45 and 50m breath-hold snorkeling (underwater 1 ~ 1.5m) before the water into the hyperventilation (8 to 10 times inhale and exhale), and before and after ventilation Exhaled gas was collected after the snorkeling, with Ergo Pneu-
