Abstract : Studies have been made on the causes of fatigue amongst the trainees in diving the Indian Navy. Sixty percent of the ratings found fit for the training were able to complete the course successfully. Of the 40 percent who failed a large percentage were found unfit medically or were not suited for diving temperamentally. only 7 percent were disqualified professionally. Main causes of rejection on medical grounds were Otis media r active veneral disease. After a first few dives a beginner felt exhausted and compression of chest. The feeling decreased with training. Greater rise in pulse rate was observed in trainees who had no previous experience in diving than in those who had undergone some training. A diver has to carry the whole weight of "Standard Diving Dress" weighing about 176lbs. during certain stages of diving. Rating with poor physical development cannot stand the strain of diving.
