AB  - Deep sea diving might cause a tremendous physical or psychological stress to the 
      divers. The present study aims to evaluate the stress response to a simulated wet 
      dive in Navy divers. Nineteen Navy divers took part in this study when they were 
      undergoing annual deep dive training. Ten divers were exposed to 190 feet of sea 
      water (fsw) breathing compressed air on day 1 and to 250 fsw breathing 
      helium-oxygen (Heliox) gas mixture on day 3. Another 9 divers were exposed to 220 
      fsw on day 1 and 285 fsw on day 3 breathing Heliox gas mixture. The bottom time 
      ranged from 5 to 8 min, and then the standard U.S. Navy air and Heliox 
      decompression tables were followed for surfacing. Predive levels of serum heat 
      shock protein 72 (sHsp72) were 9.95 +/- 0.56 ng/ml, which were significantly 
      higher than those in the control group (8.01 +/- 0.77 ng/ml). After simulating 
      Heliox dive, the sHsp72 increased to 10.43 +/- 0.56 ng/ml, but this was not 
      statistically significant. Our results demonstrated that the serum level of Hsp72 
      is higher in the Navy divers who underwent regular intensive exercise. However, 
      it remains unknown whether this increase of stress protein is associated with the 
      diving stress or exercise preconditioning in the Navy divers.
