Physiological characteristics of biochemical parameters of blood and sympatho-vagal balance in highly skilled athletes

Aim. The aim of the work was to describe hematological biochemical parameters of blood and sympatho-vagal balance in elite (IMS, n = 12) and highly skilled swimmers (CMS, n = 23). Materials and methods. Hematological (n = 10) and biochemical (n = 11) parameters were determined with automatic analyzers from venous blood. The autonomic regulation of the heart was assessed by means of spectral analysis. Results. IMS swimmers had increased levels of RBC (+ 12.5 %, p
