PURPOSE This study aimed to analyze factors associated with physical activity (PA) in older adults based on social ecological theory. METHODS Secondary analysis was conducted using raw data from the 2021 Community Health Survey. after excluding 129 non-responses in the PA domain, a total of 74,363 individuals were included in the final analysis. A total of eight factors, including personal (level of depression, history of falls), relational (relationships with neighbors, living alone), community (satisfaction with the local community system, safety), and environmental factors (living environment, natural environment), were selected in accordance with the key points of social ecological theory. To analyze social ecological factors related to the PA of older adults, we conducted a decision tree analysis using Chi-square automatic interaction detection (CHAID). RESULTS The average PA level among older adults was approximately 136 minutes, but the mode and median were both 0 minutes. A total of 20.2% of older adults met the physical activity recommendations, while 79.8% did not. According to the first split of the decision tree, living alone was the most relevant factor associated with the PA of older adults, followed by depression and falls. Older adults living alone, with a depression score of 10 or higher, and who had experienced a fall within the past year, were least likely to meet the PA recommendations. CONCLUSIONS This study urgently suggests that PA programs should target older adults living alone, experiencing depression, and falls.
PURPOSE This study sought to establish obesity diagnosis criteria by using the Body Volume Index (BVI) by body part extracted through 3D BodyScanner. METHODS The body fat percentage was measured using Dual Energy X-ray Absorptiometer (DEXA) for 225 participants (male = 119, female = 106), and BVI for eight body parts was measured using 3D BodyScanner. Independent t-test and Receiver Operating Characteristic (ROC) analysis were conducted. ROC analysis calculated the Area Under the Curve (AUC), and the optimal cut-point by Youden's J index. Sensitivity, Specificity, Accuracy, Balanced Classification Rate (BCR), and F1-score (harmonic mean of recall and precision) values were calculated to verify the validity of the optimal cut-point. RESULTS A statistically significant difference was observed in BVI by body part according to whether obesity was present for both men and women, and the obese group higher than the normal group. The optimal cut-point for each body part to diagnose obesity was 7.96 for shoulder, 9.79 for chest, 7.15 for upper abdominal, 7.71 for lower abdominal, 14.89 for total abdominal, 9.79 for thigh, 5.70 for calf, and 74.96 for total body volume in men. In case of women, this was 6.04 for shoulder, 9.82 for chest, 4.96 for upper abdominal, 6.23 for lower abdominal, 11.63 for total abdominal, 8.88 for thigh, 4.05 for calf, and 58.15 for total body volume, and the accuracy was 0.6~0.9. CONCLUSIONS BVI is a useful indicator for diagnosing obesity. However, this can be applicable only to Asian adults since there may be differences depending on race or age.
PURPOSE This study seeks to explore the subjectivity regarding leisure constraints perceived by college student-athletes. METHODS Based on Q methodology as an analysis framework, 25 Q-samples and 25 P-samples suitable for the research purpose were selected, and Q-classification and Q-factor analysis were conducted. RESULTS The leisure constraints were categorized into “Type Ⅰ: Psychological constraints,” “Type Ⅱ: Financial constraints,” and “Type Ⅲ: Spatio-temporal constraints.” The three types provided discussions on “strong athlete identity of student-athletes,” “role conflict between students and athletes,” “core competencies of student-athletes,” “current student-athlete support project,” and “school sports camp training.” CONCLUSIONS College student-athletes’ leisure constraints are closely related to strong athlete identity, anxiety about enjoying leisure, cost burden, and closedness of camp training, and each type provided new perspectives on discussions related to Korean student-athletes.
PURPOSE Inclusive leadership has become increasingly important in sport organizations. Accordingly, this study examines interorganizational inclusive leadership effects on organizational trust and affiliated organizations’ employees depending on power distance. METHODS A total of 250 affiliated sport organization employees participated, and latent moderated structural equation modeling with a bifactor structural model was employed to test the hypotheses. RESULTS The results indicated that macro inclusive leadership as well as its two components significantly enhance organizational trust. Interestingly, power distance positively moderated the macro effect of interorganizational inclusive leadership on organizational trust. Lastly, organizational trust enhanced job performance and well-being, and reduced turnover intention. CONCLUSIONS The results provide meaningful insight into the relationship between lead and affiliated organizations in the context of highly competitive and collaborative sport organizations.
PURPOSE This study aimed to investigate the effects of accelerated rehabilitation exercise on physical fitness, lower extremity isometric strength, and blood variables in older adult women diagnosed with degenerative osteoarthritis. METHODS A total of 29 older adult women diagnosed with degenerative osteoarthritis residing in G city participated in the study, and 19 participants, excluding dropouts, took part in the experiment. They underwent exercise twice a week for 60 minutes per session over a period of 12 weeks. Pre- and post-experiment, the older adult fitness assessment (SFT), lower extremity isometric strength, and blood variables were measured. Data analysis was performed using SPSS 25.0, and paired sample t-tests were conducted to examine the effects before and after exercise. RESULTS The study results showed significant differences in body mass index (BMI) before and after exercise (p<0.05), and the older adult fitness assessment (SFT) showed significant differences in all items (p<0.01). Lower extremity isometric strength showed significant differences in absolute (Nm) and relative (%BW) values of 20° right flexion muscle (p<0.01). In terms of blood variables, significant differences were observed in creatine and ESR before and after exercise (p<0.01). CONCLUSIONS This study’s results suggest that regular physical activity and rehabilitation exercise programs can positively impact the muscular strength, cardiovascular endurance, exercise function, and blood composition of older adult women diagnosed with degenerative osteoarthritis. It is indicated that conducting future research, including periodic exercise programs, could be beneficial in promoting sustained exercise participation.
PURPOSE This study aimed to explore the enactment and background of Korean and Japanese sports laws, comparatively analyze the major sports-related laws of both countries, namely Korean National Sports Promotion Act, Japanese Sport Promotion Act, and the Framework Act on Sport of both countries, and derive implications for the Korean Framework Act on Sport, sports-related laws, and sports policy. METHODS Research related to sports law were collected through academic databases and major search portals in both countries and analyzed. RESULTS First, as reviewed in previous studies, the Korean National Sports Promotion Act at the time of its enactment imitated the Japanese Sport Promotion Act in almost all articles. Second, Japanese Basic Act on sport, which was a complete revision of Japanese Sport Promotion Act, further expanded the concept of “sports,” and specified nonexistent “sports rights,” “sport nation,” and “sport as a universally shared human culture,” was evaluated as having quasi-constitutional character. Third, the Framework Act on Sport of both countries specified similar sports policies and concepts in many individual articles. The Korea’s Framework Act on Sport independently included articles for superordinate law, spread of sports values into environmental and political fields, inter-Korean exchange and cooperation in sports, sports donation culture, and so on . Japan’s Basic Act on Sport independently specified preamble, sports integrity-related articles, articles for prompt and appropriate resolution of sports disputes, and for promoting anti-doping activities, and so on. CONCLUSIONS This study offers suggestions for clarifying the legal concepts of “sports” and “physical education,” resolving contradictions in the articles of the Korean Sports-related Act, establishing an independent sports policy implementation organization, establishing the legal system of the Korean Sports-related Act, and supporting the “life career” from the time of active athletes.
PURPOSE By comparing and analyzing the sport safety policies in New Zealand, the USA, and the UK, this study sought to propose sport safety policies for people with disabilities in Korea. METHODS This study utilized a comparative research design in three steps. Policy documents were collected from the websites of institutions that directly or indirectly influence the sports safety policies for people with disabilities in each country, as well as academic articles from both domestic and international research databases. RESULTS The data analysis revealed each country’s legal basis, operating entities, and delivery systems. CONCLUSIONS Based on the results, the following implications for the development of sports safety policies for people with disabilities are presented. First, the current legislation system that serves as a foundation for the sports safety policy should be strengthened. Second, a cooperative system should be established among various operating entities related to sports for people with disabilities. Third, the delivery system of sports safety policies for people with disabilities needs to be diversified. To sustain the growing participation of such individuals in sports, developing sports safety policies and guidelines specific to people with disabilities at the national level is essential.
PURPOSE This study aimed to understand the changes in the exercise behavior of participants in the exercise-psychological counseling program. METHODS This study sampled adult female participants of C diet camp in Seoul, who were in stages 2~3 of the “Stages of Change Model.” A total of 60 participants were randomly assigned to the counseling group (n=30) and control group (n=30). During the 12 weeks of study, all subjects participated in the diet camp program C. The counseling group participated in the exercise psychological counseling program once a week, while the control group participated in recreational activities instead. Exercise adherence, outcome-expectancy, and satisfaction were measured once every four weeks. Latent growth models were used to analyze the measured data. RESULTS Exercise adherence, outcome-expectancy, and satisfaction in the counseling group exerted a statistically significant positive effect. A statistically significant positive effect on the change of exercise adherence variable was observed in the control group, but the trend was only 1/4 of that of the counseling group. In the control group, exercise outcome-expectancy and exercise satisfaction did not have a statistically significant outcome. CONCLUSIONS The exercise counseling program is an essential intervention strategy that enhances participants’ exercise adherence, outcome-expectancy, and satisfaction. Therefore, a positive change in exercise behaviors occurs.
PURPOSE This study aims to examine the mediating effect of viewing flow on the relationship between perceived authenticity among [Kick A Goal] female viewers’ and football participation intention. METHODS A total of 414 questionnaires were distributed to [Kick A Goal] female viewers, aged from 20s to 60s, who had no experience in football. Among the collected questionnaires, the data used for the final analysis was 338 after data cleaning. The data analysis was conducted using SPSS 25.0, and it included frequency analysis, descriptive statistics analysis, correlation analysis, simple regression analysis, and a three-step mediation analysis proposed by Baron & Kenny(1986). RESULTS This study’s results were as follows: First, the perceived authenticity of female viewers positively affected viewing flow. Second, the viewing flow of female viewers positively affected their football participation intention. Third, viewing flow fully mediated the relationship between perceived authenticity and football participation intention. CONCLUSIONS In summary, this study suggests that it is significant to produce programs with authenticity and maximize viewing flow to further enhance the intention of female viewers to participate in football.
PURPOSE This study conducted a longitudinal analysis of physical activity levels and characteristics of middle-school boys and girls over a three-year period before and after the COVID-19 pandemic. METHODS This study used a sequential mixed-methods research design. In the quantitative study; three-dimensional accelerometers were used to measure weekly physical activity and sedentary time over three years (2019, 2020, and 2021) among 33 middle-school boys and girls, and the data were analyzed using repeated measures analysis of variance. In the qualitative study, data were collected and analyzed through focus group interviews with five participants. RESULTS The quantitative study indicated a significant increase in sedentary behavior and significant decrease in low-intensity activity and MVPA during the first year of the COVID-19 pandemic. In the second year of the pandemic, no significant difference was observed in sedentary behavior, low-intensity activity, and MVPA compared to the data collected in the first year. During the pandemic’s first year, qualitative study identified the following physical activity problems: “lockdowns,” “sedentarization of leisure,” and “reduced structured physical activity.” The following reasons were identified for the lack of improvement in physical activity during the second year: “intensified sedentary lifestyle habits,” “weak social networks,” and “lack of energy to exercise.” CONCLUSIONS The COVID-19 pandemic has led to a significant decrease in physical activity and a significant increase in sedentary behavior among middle-school students in South Korea, and even as the environments for physical activity have recovered, the physical activity problems of the early stages of the pandemic have not improved.
