Abstract
In order to obtain the informations of fatigue and emotional state of divers living in hyperbaric (31 ATA, He-02) underwater simulation for long term, three questionaires-subjective sysmptoms of fatigue, mood adiective check list, , and State-Trait Anxiety Inventory (STAI), ware performed with appropriate intervals. Hyperbaric experiment was consisted of five phases, pre-dive control, compression, saturation at 31 ATA, decompression and post-dive observation. Four divers lived in this situation for about total of 30 days. Though there was variation between subjects, three indices revealed that fatigue, especially the physical one and state anxietny increased in the period of compression, though possitive or active mood was persisted throughout the experiment. Results lead us to the discussion that compression is a facter of both physical and emotional fatigue rather than decompression.
