The aim of this study was to examine the decision-making performance of experienced and inexperienced soccer players at four exercise intensities (rest, 40%, 60%, and 80% maximal aerobic power). The decision-making performance of inexperienced players was expected to demonstrate an inverted-U shape with increasing levels of exercise. For the experienced players, decision making was predicted to show no change in performance with increased exercise intensity. Thirty-two adult soccer players (16 experienced, 16 inexperienced) were asked to answer seven decision-making questions as quickly and accurately as possible for each exercise intensity. Results indicated that exercise does not affect the accuracy of decision making; however, the speed of decision making for experienced and inexperienced players improved with increased exercise intensity. These results suggest that physiologically induced arousal only affects speed of decision making.
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.
Motor learning textbooks provide specific recommendations for the use of whole and part practice during motor skill acquisition. Magill recommended basing decisions on Naylor and Briggs' hypothesis of task complexity and organization, while Schmidt and Wrisberg recommended basing decisions on skill classification. To evaluate the accuracy of these recommendations, a meta-analysis was conducted. Through a literature search, 44 articles were located, and 20 provided sufficient information to calculate effect sizes. Effect sizes were calculated using means for whole and part practice for acquisition and retention. Although several analyses were compromised by insufficient studies investigating whole and part practice, mean effect sizes generally supported motor learning textbooks. To better verify the empirical validity of recommendations for the use of whole and part practice, more studies are necessary.
Mastery of fundamental movement skills (FMS) is an important factor in preventing weight gain and increasing physical activity. To master FMS, performance evaluation is necessary. In this study, we investigated the reliability of a new observational assessment tool. In Phase I, 110 video clips of children performing five locomotor, and six manipulative FMSs were developed. In Phase II, rating scales were developed, and their efficacy was evaluated by comparing judgments of 30 undergraduate students to a standard. The mean weighted kappa (.71) was considered good (range .51-.85). Of the 11 rating scales, 6 were modified, and 5 remained unchanged. This study sets the foundation for the development of a new observational scale to assess fundamental movement skills.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
