The effect of nutrition education intervention on total calorie intake, macronutrient content, iron and vitamin D status of competitive adolescent soccer players

In addition to daily calorie intake, vitamin D and iron as micronutrients are the most important in the diet of athletes, especially in adolescence. Therefore, the aim of the present study was to investigate the effect of nutrition education intervention on total caloric intake, resting levels and iron and vitamin D intake in competitive adolescent soccer players.

The subjects of this study consisted of 63 competitive adolescent soccer players in the country's premier league. In order to achieve the total caloric intake and the amount of micronutrients, the subjects were recalled for three days, then blood samples were taken to achieve resting amounts of vitamin D and iron. Nutrition education intervention group (n = 41) and control group (n = 22) The experimental group was trained for 4 weeks (8 sessions of 30 minutes of applied nutrition educating followed by 10 weeks of face-to-face counseling) by attending the website and online. To examine changes within and between groups of analysis Mixed variance and dependent and independent t-tests were used.

The results of intragroup mixed analysis of variance test on total calories, resting levels of vitamin D and vitamin D in the diet were significant (P = 0.001).

Nutritional education intervention significantly increases total caloric intake, carbohydrate and protein intake, resting levels of vitamin D and intake of vitamin D in the diet of competitive adolescent soccer players, but on resting values and Dietary iron intake has no effect.
