Psycho-physiological examinations of seamen during a voyage on a Mediterranean line

During a voyage to the countries of the Mediterranean there were performed medical and psycho-physiological examinations of the whole crew of a ship--at the beginning and towards the end of the voyage. The researchers availed themselves of routine medical methods of examination, examination of the reactivity of the vegetative system and psychological tests. In most of the cases no significant changes were found in the parameters under scrutiny--towards the end of a 60-day voyage. A voyage of that duration and shipping made on this route did not affect the psycho-physiological efficiency of the crew.
