Relationships of inflammatory activity with biochemical parameters of the blood and sympathovagal balance of young athletes

Abstract

Results of numerous studies show that a specific combination of biochemical parameters is formed in a trained body. The systemic inflammatory activity is supposed to be an integral factor involved in the formation of such a specific biochemical profile. The measurements of biochemical parameters of athletes’ blood and sympathovagal balance (via the assessment of the heart rate variability) performed in this study show that a decreased level of C-reactive protein is correlated with the count of red blood cells, hematocrit, levels of neutrophils and lymphocytes, total concentration of cholesterol and its concentration in low-density lipoproteins, activity of creatine phosphokinase, time of heart rate recovery from 170 to 120 beats/min (the HR170-120 index), and the LF/HF ratio (regarded as a marker of the sympathovagal balance). Hence, a decreased inflammatory activity can be involved in the regulation of some biochemical parameters and affect the sympathovagal balance of a trained body.
