The aim of this study is to examine the relationship between body mass indexes and nutritional habits of national cycling athletes. In 2020-2021, 20 elite/national cyclists, including 10 sprinters and 10 hill climbers competing in the Turkey Cycling Spindle Team, participated voluntarily. The averages of age, height and body mass indexes of the cyclists participating in the study were respectively for sprinters; 23.40 +/- 2.68 years, 1.76 +/- 0.04 meters and 23.31 +/- 1.68 kg/m(2), while for hill climbers it is 24.10 +/- 3.64 years, 1.76 +/- 0.05 meters and it was determined 21.39 +/- 1.02 kg/m(2). The data obtained in the study were analyzed in computer environment. Spearman Correlation analysis was applied for the research results. In the study, it was seen that the BMI values of the athletes were normal and the sub-headings of their eating habits were above the average. In addition, no relationship was found between BMI and eating habits and total scores.
