Petrie and Greenleaf's sociocultural model proposes that athletes experience unique sport environment pressures regarding weight, body size/shape, eating and appearance that increases their risk of developing disordered eating (DE) attitudes and behaviors. Although research in cross-correlational studies has looked at prevalence of eating disorders (ED) and DE behaviors in different sport types, such pressures are likely to vary by sport depending on its unique environment and performance demands. For instance, female athletes in leanness sports experience more body dissatisfaction and societal appearance pressures compared to those in nonleanness sports. Because these effects have been established primarily with female athletes, I examined ED/DE correlates from Petrie and Greenleaf's model with 695 collegiate male athletes who represented five sport types (endurance, ball game, power, technical, weight-dependent) based on a well-established categorization system. Through a series of one-way MANCOVAs (BMI serving as the covariate), I found that sport types were significantly different from each other on all ED/DE correlates except for negative affect. Follow-up analysis revealed that power, endurance, and weight-dependent athletes showed the greatest number of significantly different group centroids, demonstrating distinct profiles among the sport types in their experiences of the ED/DE correlates. Discussion focuses on possible explanations for the research findings, future directions, and clinical implications.

Introduction: Physical activity should be part of our everyday life. However, for people with Type 1 Diabetes Mellitus it is the most common cause of hypoglycemia. To control diabetes in the right way, it is therefore necessary to follow certain rules and recommendations that help preventing hypoglycemia while the physical activity remains beneficial at the same time. Aim of the work: The main aim of this study is to clarify the influence of physical activity in connection to long-term control of Type 1 Diabetes Mellitus. Methods: 102 respondents with diagnosed Type 1 Diabetes Mellitus in the age of 19-69 years participated in a quantitative analysis. This research was conducted in a form of multicentric examination at two independent medical centers. The data collection was done through questionnaires focused on physical activity and daily regime. The data from questionnaires were then compared to the values of glycated hemoglobin (HbA1C), HDL cholesterol and the total daily dose of insulin of certain patients. For statistical evaluation, analytical tools of Microsoft Office program were used (F-test and t-test). Results: We found correlation between HbA1C values in patients physically active for less than 2 hours/week compared to those who are physically active for more than 2 hours/week (62,72...
