EVALUATION OF VITAMIN CONTENT AND LIPID PEROXIDATION IN THE BLOOD SERUM OF ATHLETES WITH SCOLIOSIS AND IRON-DEFICIENCY ANEMIA

Abstract

Aim. The paper aims to assess vitamin (A, C, carotene) and iron content, as well as peroxidation activity in the blood serum of athletes with scoliosis and anemia. Materials and methods. 620 adolescents aged from 13 to 18 were randomly selected. All participants were under clinical supervision at a medical and physical education clinic in Veliky Novgorod. Of these adolescents, 3 groups were formed for further analysis: 1^st group – apparently healthy adolescents (n = 20),
2^nd group – adolescents with iron-deficiency anemia (n = 20), 3^rd group – athletes with scoliosis and iron-deficiency anemia (n = 10). Blood test results were evaluated. The serum levels of vitamin A, C, carotene, iron and malondialdehyde were measured. Vitamin C content was determined in the urine samples. ECG indicators were analyzed before and after exercise. Results. It has been found that athletes with both scoliosis and anemia demonstrate significant changes in terms of vitamin A and C levels, which trigger the processes that result in oxidative stress. These changes can be one of the causes of frequent (in 50% of cases) ECG changes under exercise in this group of athletes (extrasystole, transient SA block II degree). Conclusion. Iron-deficiency anemia is mostly identified for the first time during a routine examination. Athletes with scoliosis and iron deficiency anemia are advised for further medical examination and operational monitoring of regulatory mechanisms, including vitamin content in blood serum, due to hypoxia and lipid peroxidation.
