Dysbarism or decompression illness (DCI), a general term applied to all pathological changes secondary to altered environmental pressure, has two forms decompression sickness (DCS) and arterial gas embolism (AGE) after pulmonary barotrauma. Cerebral and spinal disorders have been symptomatically categorized as AGE and DCS, respectively. Magnetic resonance images (MRIs) of divers with DCI showed multiple cerebral infarction in the terminal and border zones of the brain arteries. In addition, there were no differences between MRI findings for compressed air and breath-hold divers. Although the pathogenesis of the brain is not well understood, we propose that arterialized bubbles passing through the lungs and heart involved the brain. From the mechanisms of bubble formation, however, this disorder has been classified as DCS. We propose that there is a difference between clinical and mechanical diagnoses in the criteria of brain DCI. In contrast to brain injury, the spinal cord is involved only in compressed air divers, and is caused by disturbed venous circulation due to bubbles in the epidural space. The best approach to prevent diving accidents is to make known the problems for professional and amateur divers.

Decompression illness(DCI) may theoretically be possible which is following after breath-hold dives because the nitrogen gas is accumulated in blood and tissues. Since the 1960s, when Cross reported Taravana diving syndrome in Polynesian pearl divers, the occurrence of diving accidents has been widely debated. However, such incidents have not been reported for more than 3 decades. Recently, we have encountered 2 Japanese professional breath-hold (ama) divers with a history of diving accidents. Our interview survey showed in their island that many ama divers had previously experienced transient stroke-like neurological accidents, in which the most common symptoms were unilateral motor weakness and sensory abnormalities. In addition, we have treated another 2 ama divers who suffered visual disturbance or motor weakness in one side during deep repetitive breath-hold dives. Brain magnetic resonance imagings of above 4 ama divers showed multiple cerebral infarction in the terminal and border zones of the brain arteries. Although the pathogenesis of the brain lesions is not well understood, we propose that arterialized bubbles passing through the lungs or heart involved the brain. In breath-hold divers, DCI involved the brain looks like clinical signs as arterial gas embolism following pulmonary barotrauma. From the mechanisms of bubble formation, however, this disorder has been classified as decompression sickness. We propose that there is a difference between clinical and mechanical diagnoses in a criteria of brain DC. (author abst.)

フリーダイビング…それは人類の原初、海に回帰する最良の手段。 SCUBAなどという道具に頼ることなく、身一つで母なる海に抱かれる。 目を閉じて、耳を澄ませば・・・、 地上では決して聞こえることのない地球の鼓動が聞こえてくる。

伝説のフリーダイバー、ジャック･マイヨールは言う。 現実という拘束から身も心も解き放ち、 イルカや鯨たちのように自由に海に游ぶ。 それがフリーダイビングの醍醐味だと。

そして新たなるグランブルー伝説を紡ぐ男、 ウンベルト･ペリッツアーリは言う。 人は誰もが、心のどこかに海の切れ端を宿している。 海の切れ端とは人類創生の遠い記憶である。 そして、その切れ端がざわめいたとき、 人は知らず知らずのうちに海の深淵を目指すのだと。

Our objective is to support and upgrade any level of ocean loving freedivers in their quest to maximze the sensory experience through the necessary study of theory and practice, so as to make the sport safe, relaxed, environmentally friendly and enjoyable for all.

We have organized the MUGEN team for developing all Apnea abilities, and we aim to enter International Apnea competitions. But now we seldom have time to get all the members together, because we all live in different areas of Japan.

In the near future, we are planning to have training sessions, etc, not only with our team members, but also other freedivers interested in Japan. Sorry, but we don't want new members now (we need time). At the present time, the things we can do for freedivers in Japan is to only send messages, and to communicate with you all through our pages.

Through this homepage, we want to communicate with freedivers throughout Japan and the world. And we want to create many freediving friendships and contacts. Of course we want you to know about us, the Team Mugen. If you have any questions or concerns about Apnea diving, please do not hesitate to contact us.
