Female Athletes Explicitly Gesture In Emotional Situations, Y. Adams, M. Augenstein, P. Furley, A. Krieg, P. Born, I. Helmich

Exercise and Sport Studies: Faculty Publications

Introduction: Both appraisal emotion approaches and self-regulation theory emphasize that appraising an event as conducive or detrimental to one’s current goals may trigger an affective response that can be observed nonverbally. Because there may be a female advantage in the inhibition and self-regulation of emotions, we hypothesized that female but not male athletes regulate emotions during sports through explicit nonverbal behaviors. Methods: All nonverbal hand movement behavior of right-handed female and male tennis athletes was recorded during competitive matches. All immediate nonverbal expressions after point losses and wins were coded by two independent blind raters applying the NEUROpsychological GESture (NEUROGES®) …

Exploring Usability In Exercise Interventions: From Conceptualization To Measurement And Application, Anne Inger Mørtvedt

Dissertations, Master's Theses and Master's Reports

Exercise interventions hold promise for preventing and treating numerous conditions, diseases, and injuries. However, these interventions will only be effective if they are being used. Unfortunately, uptake and adherence to prescribed exercise and physical activity guidelines are insufficient. Some reasons for this include lack of knowledge, resources, flexibility, and enjoyment. Exercise program developers need to not only consider the effectiveness of the program during the development phase, but also involve end-users and receive feedback on program usability to determine likelihood of uptake and adoption. Usability testing can be used to detect barriers to use and implementation likelihood but has not …
