Abstract

A blood test for vitamin D(OH) reflects a person's overall health. Athletes in the winter season have a sharp decrease in the concentration of calcitriol in the blood. Taking cholecalciferol by athletes at a dose of 2000 IU per day allows one to maintain vitamin levels at a sufficient level in the body, which contributes to maintaining good physical shape and improving athletic performance. Level 25(OH) analysisD in the blood of elite athletes is useful for monitoring and correcting the intake of vitamin D preparations, requires mandatory implementation in the medical and biological support of national teams.
