STUDY CORRELATION OF MACRO- AND MICROELEMENT SALIVA OF CHILDREN AND TEENAGERS, EXERCISE
The study included 130 children and adolescents between the ages of 12 to 17 years 11 months. Among them, 102 children with intensive physical activity level (intense exercise at least 12 hours a week - 3 or more times per week for the last 6 months or more). Study content elements calcium, potassium, magnesium, iron, zinc, chromium and selenium in saliva of children and teenagers were performed by atomic emission spectrometry with inductively bound plasma on the device Optima 2000 DV, PerkinElmer / US (magnesium, potassium, calcium, and iron) and inductively coupled plasma mass spectrometry for Elan 9000 instrument, PerkinElmer Sciex / US (chromium, zinc, selenium). It was found, the content of chemical elements in the study of biological substrates depends on the type and age of sports athletes.
