Effect of body composition on the athletic performance of soccer referees.

Nutrition plays an important role in improving sports performance. The present study aimed at nutritional assessment and examined the relationship between athletic performance and body composition in soccer referees at different levels. The study participants were 120 male soccer referees. 5, 10 and 30 metres (m) sprint tests to measure speed and cooper test for physical fitness were applied in the referees. Participants were divided into two groups as city and class soccer referee. The anthropometric measurements, excluding fat mass (FM) (%), were higher in class referees. Fat mass (%) differences (14⋅1 ± 4⋅28 v. 12⋅3 ± 4⋅41) were statistically significant (P < 0⋅05). Daily energy and nutrient intakes were similar. The inadequacy percentages of energy, vitamin A and calcium were the highest (29⋅2, 30⋅0 and 34⋅2 %, respectively). It was found that a negative significant correlation between FM% and cooper test score (P < 0⋅01; r = -0⋅35), a positive significant correlation between FM% and 5, 10 and 30 m sprint test scores (P < 0⋅01, r = 0⋅38; P < 0⋅01, r = 0⋅38 and P < 0⋅01, r = 0⋅48, respectively). Similarly, there was a negative significant correlation between waist circumference (WC) and cooper test score (P < 0⋅01; r = -0⋅31), a positive significant correlation between WC and 5, 10 and 30 m sprint test scores (P < 0⋅01, r = 0⋅33; P < 0⋅01, r = 0⋅40; P < 0⋅01, r = 0⋅33, respectively). Nutritional recommendations for soccer referees should be made specific to the individual, considering body composition, training intensity and match frequency by a dietician.

Assessment of food consumption changes in adolescents during orthodontic treatment.

INTRODUCTION: This study aimed to evaluate the changes in food consumption in adolescents during orthodontic treatment. METHODS: Twenty-five adolescents aged between 12 and 18 years participated in the study. Before the treatment, the participants were interviewed, and their food consumption frequency and 24-hour retrospective food consumption records were taken. Participants were followed up for 3 months, that is, in the first, fourth, and 12th week of the treatment. In the interviews, questions about food consumption changes and posttreatment pain were asked to the participants, and 24-hour retrospective food consumption records were obtained. RESULTS: When the food consumption records of the adolescents before the orthodontic treatment and at the first week, first month, and third month of the active orthodontic treatment were compared, there was no significant difference between total energy, protein, and carbohydrate intake. However, total fat intake decreased in the first week of treatment and increased significantly during the treatment period (P = 0.05). There was a significant decrease in the amount of fiber (P = 0.039), vitamin E (P = 0.043), and vitamin C (P = 0.048) intake of patients during the orthodontic treatment. CONCLUSIONS: Nutrition and feeding habits are important for growth and development in adolescence. In adolescents having orthodontic treatment, vitamin C, vitamin E, and fiber intake decreased significantly, especially in the first weeks of treatment. The intake of these nutrients did not return to their initial levels by the 12th week of the orthodontic treatment. It is thought that cooperation with dietitians and orthodontists might minimize the undesired nutritional effects of the orthodontic treatment.
