Anti-fat bias by professors in physical education departments may interfere with the training provided to pre-service teachers. The purpose of this study was to evaluate the attitudes of professors in physical education departments toward obese individuals. Professors from randomly selected institutions across all four US regions participated in the study (N = 94). Participants took the Implicit Association Test and answered the Anti-Fat Attitude Scale and two questions specifically designed to measure their attitudes toward physical education teachers and majors who are obese. The participants exhibited implicit good-bad (p < .001) and lazy-motivated (p < .001) anti-fat biases. Professors favored accepting majors who are obese (p < .001), but they strongly disapproved of obese physical education teachers as role models to their students (p < .001). Explicit anti-fat bias was associated with a stronger disapproval of physical education teachers who are obese as role models to students (p < .001) and accepting majors who are obese (p < .001). Implicit good-bad anti-fat bias was associated with a stronger disapproval of obese physical education teachers as role models to students (p = .047). The anti-fat bias demonstrated by the professors may negatively affect the training of pre-service physical education teachers to work with students of all body sizes. Awareness programs may be necessary to diminish anti-fat bias among professors in physical education teacher education programs. [ABSTRACT FROM AUTHOR]

Research has shown that interest in knowledge facilitates students' academic achievement in learning. Because individual interest is often based on how much one knows, in other words existing or prior knowledge, studying adolescents' interest in health-enhancing physical activity and its benefits should address the relation between the interest and their existing or prior physical activity knowledge. Understanding this relationship may help us facilitate students to not only develop interest in knowing more about but also actual adopt a healthy, active lifestyle. This study used a large-sample structural equation design to identify the relationship between middle school students' interest in physical activity knowledge and their prior physical activity knowledge, and to assess the change of this relationship over time. Guided by the declarative-procedural knowledge framework, latent growth models were developed and tested on data collected from a random sample of 3882 students from ten middle schools. The latent growth curve model indicated that, 1) on average, students experienced a significant interest decline in both procedural and declarative knowledge; 2) prior knowledge helped slow the decline and facilitated interest growth in knowledgeable students. The results suggest that existing knowledge determined the interest change. [ABSTRACT FROM AUTHOR]
