The influence of moderate hyperbaric environment on the sensory-neuro-motor processes in man.
Thirteen healthy male divers were repeatedly studied during the exposure to a moderate hyperbaric environment of 4--6, 7 and 9 ATA, in a hyperbaric chamber. The maximal duration of the exposure was 35 min, and that of decompression 90 min. As compared to the dynamics of the changes found in 14 controls, under hyperbaric conditions a significant increase in the number of static tremor, an impairment of the sensory-motor performance in O'Connor's and in the rotation test were found and also of the muscular strength and resistance to fatigue (this latter only at 9 ATA).
