Misremembering Past Affect Predicts Adolescents’ Future Affective Experience During Exercise

Purpose: Increasing physical activity among adolescents is a public health priority. Because people are motivated to engage in activities that make them feel good, this study examined predictors of adolescents’ feelings during exercise. Method: During the 1st semester of the school year, we assessed 6th-grade students’ (N = 136) cognitive appraisals of the importance of exercise. Participants also reported their affect during a cardiovascular fitness test and recalled their affect during the fitness test later that semester. During the 2nd semester, the same participants rated their affect during a moderate-intensity exercise task. Results: Affect reported during the moderate-intensity exercise task was predicted by cognitive appraisals of the importance of exercise and by misremembering affect during the fitness test as more positive than it actually was. This memory bias mediated the association between appraising exercise as important and experiencing a positive change in affect during the moderate-intensity exercise task. Conclusion: These findings highlight the roles of both cognitive appraisals and memory as factors that may influence affect during exercise. Future work should explore whether affect during exercise can be modified by targeting appraisals and memories related to exercise experiences.     

Researchers’ Perceptions of Statistical Significance Contribute to Bias in Health and Exercise Science

We surveyed researchers in the health and exercise sciences to explore different areas and magnitudes of bias in researchers’ decision making. Participants were presented with scenarios (testing a central hypothesis with p = .06 or p = .04) in a random order and surveyed about what they would do in each scenario. Participants showed significant bias in deciding to randomize additional participants when p = .06 (24.5%) compared to when p = .04 (6.5%), χ² = 19.86, odds ratio (OR) = 13.5. Based on this bias to randomize additional participants, we present statistical simulations showing the cumulative negative effect this bias has on the false positive rate for a field. While it is important for researchers to have flexibility in their data-processing decisions, there is a cost/benefit trade-off to experimenter degrees of freedom and it is important that these decisions be unbiased. These data highlight the importance of a priori analysis plans in research.     

‘Cuidar Muito em Educar as Crianças Segundo a Natureza’! Portuguese Contributions to Eighteenth- and Early Nineteenth-Century Health,Exercise and Educational Reform

The importance of exercise and physical education in relation to the health and development of children and youth has been of recurring interest. During the eighteenth and early nineteenth centuries a remarkable number of educators, physicians, philosophers, and even an occasional political leader addressed the topic and/or proposed means by which these would be incorporated into educational programs and reforms. Although the work of Rousseau, Guts Muths, and several other European authors is well known, developments on the Iberian peninsula have received little attention in the English-language press. This contribution examines events and ideas that occurred in and/or had strong connections with Portugal during the eighteenth and early nineteenth centuries.     

It is time to consider athletes’ well-being and performance satisfaction: The roles of authentic leadership and psychological capital

The purpose of this study was to examine the relationships among coaches’ authentic leadership and athletes’ psychological capital (PsyCap), performance satisfaction, and psychological well-being. The authors recruited 224 athletes participating in intercollegiate athletics in the United States. The results indicated that the authentic leadership of the head coaches positively influenced the athletes’ PsyCap levels. The enhanced PsyCap, in turn, positively influenced both performance satisfaction and psychological well-being. The interaction effect of student development was found in the relationship between authentic leadership and PsyCap. The findings contribute to an improved understanding of a head coach’s authentic behaviors in sport teams, and also illuminate how athletes’ performance satisfaction and psychological well-being can be augmented by PsyCap enhancement.
