Correlations of adaptive potential with metabolic factors in workers of the Yakutia river fleet

Abstract

Aim. To assess correlations of adaptive potential (AP) with metabolic factors in workers of the Yakutia river fleet before and after the voyage in order to assess the impact of a long voyage.Materials and methods. Before a long voyage in 45 men, a questionnaire was conducted, measurement of height, body weight, heart rate, blood pressure, determination of body mass index and AP. The correlation of AP (according to R.M.Baevsky) with biochemical (aspartate transaminase, alanin transaminase, alkaline phosphatase, gamma glutamyl transferase, lactate dehydrogenase, creatine kinase, glucose, cholesterol, triglycerides) and hormonal (TSH, free T3, free T4, testosterone, cortisol) indicators was evaluated, and also with blood plasma metabolites (62 metabolites) determined by gas chromatography with mass spectrometry before after a long voyage.Results. Distribution by AP level of rivermen – 37.8% have satisfactory adaptive potential, 24.4% have functional stress of adaptive mechanisms, 20.0% have unsatisfactory adaptation and 17.8% have a sharp decrease in the functional capabilities of the circulatory system with the phenomenon of disruption of adaptive mechanisms. The revealed correlations of AP have associations with age, overweight, obesity and metabolic syndrome. Correlations were found with creatinine, testosterone, palmitic acid before the long voyage, and with creatine kinase, glucose, urea, testosterone, gluconic and threonic acids after the voyage. After a long voyage, the number of correlations of AP with metabolic parameters increases.Conclusion. In workers of the Yakutia river fleet the revealed results of metabolic changes indicate an aggravation of disadaptive changes in the conditions of a long voyage. Taking into account the identified features, it is necessary to carry out preventive measures to reduce the severity of disadaptive metabolic changes during a long voyage and rehabilitation actions after the voyage.
