Definition of the total antioxidant capacity and vitamin D levels in professional athletes who play football in Giresunspor

Abstract

Objective: A sufficient amount of vitamin D levels; while protein synthesis, muscle strength, jumping height, speed, exercise capacity, and physical performance increase; stress fractures cause a decrease in the rates of injury, fall, muscle relaxation, muscle pain, and weakness. Serum 25-hydroxy vitamin D (25(OH)D) levels are very important for maintaining and improving optimal performance in football players. The formation of free radicals and oxidative stress during exercise is known to affect optimal performance and recovery period after exercise. The aim of the study was to determine serum 25(OH)D and total antioxidant capacity of professional football players. Methods: The study group consists of 56 professional football players (26 players from the first team, 30 players from the academy team) playing in Giresunspor Football Club. The control group consisted of 30 volunteer healthy male subjects. The SPSS 21 package program was used to calculate and interpret the survey data applied face to face to the study group. In addition, the body composition of the players was determined by the InBody 230 device which works with the principle of bioelectric impedance analysis (BIA). Serum 25(OH)D levels of the football players were compared with reference values (≥30 ng / mL). Serum 25(OH)D levels were determined by immunoassay method on the Roche Cobas e411 branded test analyzer. Serum total antioxidant capacity was compared with 30 healthy volunteers in the control group. Total antioxidant capacity measurements were studied with the ready-to-use kit. The method previously described for the kit has been applied to Architect c8000 clinical chemistry autoanalyzer.Results: As a result of the study, mean serum 25(OH)D levels of the players were determined as 31.68 ng / mL. The mean serum antioxidant capacity of the participants was found to be 1.97 mmol Trolox Equiv/L. The mean serum antioxidant capacity of the control group was 1.94 mmol Trolox Equiv/L.Conclusion: Mean serum 25(OH)D levels of the players were within the reference range (≥30 ng/mL).There is an increase in metabolic rate during training, which leads to a rapid release of free radicals. Despite this thought, there was no significant difference in serum total antioxidant capacity between the study and control groups.
