Abstract
The prospects of studying the resistance to decompression sickness of professional divers are considered. 36 men and professional divers aged 21-37 years were examined. Based on echolocation data after a standard supersaturation of the body with air nitrogen in a pressure chamber (air compression up to 0,4 MPa (30 m water) over 7 minutes, isopression60 minutes, decompression 63 minutes), 8 people were unstable and 28 resistant to decompression gas formation. It has been established that the resistance of professional divers to decompression sickness is determined by their anthropometric (age), physiological (minimum distance between R-R teeth according to the results of variational pulsometry) and psychological indicators (level of development of spatial thinking, level of reactive anxiety). For stable divers, the age and minimum distance between the R-R tines are statistically significantly less than for unstable ones. Unstable have a statistically significantly higher level of development of spatial thinking and the level of reactive anxiety. When conducting a discriminant analysis using the «forward step by step» method, a model for predicting resistance to decompression sickness is obtained: Lambda Wilks:0,27584 approximate F (4,31)=20,346; p
