Thus, this study aimed to estimate the effect size of physical activity as an alternative tool for depression symptoms using meta-analysis. A meta-analysis on depressive symptoms was performed on 18 studies published in Korean domestic journals. The moderating variables hypothesized in this study included age groups of participants; depressive symptoms; and frequency, intensity, time, type, and duration of the intervention. The overall effect size of physical activity on depression was moderate (0.56 [95% CI: 0.39 to 0.91]). Specifically, physical activity was slightly more effective in reducing depression in participants with an 18-64 age group compared to older people over 65 years old, while it was most effective for participants without depressive symptoms compared to participants with mild and severe symptoms. Further, the subgroup analysis revealed that performing two times a week for 30 to 60 min with progressive intensity for 1-8 weeks may be the most effective for Koreans. The results of this study can provide guidelines for the most effective physical activity program for Koreans. 2022-10-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/184908 Title: Applying Gamification Principles and Therapeutic Movement Sequences to Design an Interactive Physical Activity Game: Development Study Authors: Kim, Hyungsook; O'Sullivan, David Michael; Chung, Seong Hee Abstract: Background: Depression is a severe illness that has accelerated with the spread of COVID-19 and associated lockdowns. As a result, reported physical activity has substantially decreased, further increasing depressive symptoms. Objective: This study aims to explain the use of gamification principles to develop content for an interactive physical activity game for depression based on clinically proven depression diagnostic criteria. Methods: We discuss related work in this field, the game design framework, the users' depression severity, how we customize the contents accordingly, the gradual progression of the game to match exercise principles, and user flow optimization. Results: We provide a brief description of each of the games developed, including instructions on how to play and design aspects for flow, audio, and visual feedback methods. Exergames (interactive physical activity-based games) stimulate certain physical fitness factors such as improving reaction time, endurance, cardiovascular fitness, and flexibility. In addition, the game difficulty progresses based on various factors, such as the user's performance for successful completion, reaction time, movement speed, and stimulated larger joint range of motions. Cognitive aspects are included, as the user has to memorize particular movement sequences. Conclusions: Mental health issues are linked to behavior and movement; therefore, future physical activity-based interactive games may provide excellent stimulation for inducing user flow, while physical activity can help train various physical fitness factors linked to depression. 2022-10-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/139835 Title: Development of a Conceptual Model of Occupational Stress for Athletic Directors in Sport Contexts Authors: Lee, Ye Hoon; Kim, Hyungsook; Park, Yonghyun Abstract: Previous studies have reported that occupational stress is a determinant risk factor for both chronic diseases and job performance among organizational leaders. Every occupation has its own culture and occupational climate influencing organizations within the industries. Thus, due to the idiosyncratic features inherent in sports, athletic directors may experience different occupational stressors. To date, there has been no comprehensive review of the occupational stress in athletic director contexts. Thus, based on the literature on both occupational stress and sport leadership, this study proposes a conceptual framework of occupational stress in sport leadership. The model identifies the five higher-order themes of occupational stressors and their associations with the first-level outcomes of individuals and the second-level outcomes of organizations. It also includes the two higher-order moderators of personal and organizational factors. It is hoped that this initiative can invoke interest in this topic to provide health-enhancing environments for athletic directors and quality sport services to society. 2022-01-01T00:00:00Z
