Purpose The purpose of this study was to investigate the relationship between physical activity and depression according to the presence of disease. Methods A survey and basic assessment were conducted for 2,754 (Male=1,025 and Female=1,729) aged 40 and over who participated in the rural-based cohort study. The survey included physical activity, depression scale and disease preservation. The basic assessment measured height, weight, and body fat percentage. The measured data were analyzed by using logistic regression to examine the relationship between physical activity and depression prevalence. Results First, physical activity reduced the prevalence of depression by 33% and 51%, respectively, in the general population and in patients with the disease. Second, physical activity once or twice per week reduced the prevalence of depression in patients with disease by 51%, and at least three physical activities reduced the prevalence of depression by 37% in the general population and 33% of patients with disease. Third, physical activity less than 150 minutes per week reduced the prevalence of depression in patients with disease by 43%, and physical activity of more than 150 minutes and less than 300 minutes per week reduced the prevalence of 43% of the general population and 52% of patients with disease. Physical activity over 300 minutes per week had a 38% reduction in the prevalence of depression in the general population. Conclusions This study suggests that the level of physical activity suggested by the ACSM guidelines is appropriate to reduce the prevalence of depression. In addition, the patients with the disease was found to be effective with less frequency and amount of physical activity than the general person.
Circadian rhythm (CR) is an intrinsic process that changes in a cycle of approximately 24h/day to maintain body homeostasis. It is mainly controlled by the central command through the suprachiasmatic nucleus, and modern society features can disturb the central CR, contributing to various diseases. Recent studies have provided evidence that extrinsic factors, such as regular physical activity (RPA) and timerestricted feeding (TRF), can also alter the CR peripherally, emphasizing RPA and TRF as the non-therapeutic methods for circadian misalignment (CM). Therefore, this review scrutinizes the regulatory mechanism of CR and summarizes the relationships between CM and various diseases. In addition, by reviewing studies investigating the prevention or improvement of CM via RPA and TRF, the value of circadian biology research that can directly affect health, physical function, and lifespan is summarized. By introducing the scientific evidence for RPA and TRF to maintain and improve CR, we tried to emphasize the importance of regular exercise and healthy eating habits to people in the modern world who have difficulty maintaining CR.
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 Sport has become a popular platform for corporate social responsibility (CSR) campaigns. Growing numbers of athletes, teams, and organizations are engaging in CSR campaigns to promote awareness and behaviors to support CSR campaigns addressing pressing social issues (e.g., disease prevention, health promotion, etc.). However, much of the previous work has focused on whether such initiatives benefit the organization, but not the community. The present paper provides theoretical explanations on the psychological mechanism that can demonstrate how consumers respond to CSR campaigns initiated by a sport organization. Method In particular, existing literatures in moral psychology and CSR have been reviewed to identify an explanatory mechanism that promote prosocial behavior among sport consumers. Results The present paper posits that moral emotion is a central processing mechanism explaining the link between CSR and socially responsible behaviors in consumers. The paper also provides a theoretical account to explain how moral emotions are evoked in the CSR context and how they can prompt prosocial behaviors. Conclusion This paper adds to the literature by answering the call for the need to understand underlying mechanisms linking CSR with positive social outcomes (cf. Aguinis & Glavas, 2012).
Purpose This study aimed to evaluate the nutrient intakes and diet quality of national youth badminton players participating in summer camp training in 2016. Methods Total of 40 middle school players and 60 high school players were included in the study. Two players with skipped meals were excluded from the final target. Food intake data for the 3-day using 24-hour recall method were obtained and analyzed using the CAN-pro 5.0 (Web ver. Korean Nutrition Society, Korea). Differences in nutrient intakes and diet quality were compared between middle school players and high school players using independent samples t-test. Results Intakes of vitamin C, vitamin E, vitamin B6, folic acid, calcium, chloride, magnesium, and zinc in both groups were lower than (RNI) recommended intakes of KDRIs. On the other hand, intake of sodium significantly exceeded the recommended nutrient intake (RNI) of KDRIs in both groups. The NARs (Nutrient Adequacy Ratio) of vitamin C, vitamin B6, folate, calcium and zinc were less than 0.75 in both groups. The NARs of 11 nutrients except for folic acid were significantly lower in high school players. The MAR (Mean Adequacy Ratio) of middle school players was 0.78, significantly higher than 0.64 of high school players. The INQs (Index of Nutritional Quality) of vitamin C, vitamin B6, folic acid, calcium and zinc were less than 0.75 in both groups. The INQs of vitamin A, vitamin B6 and zinc were significantly lower in high school players. On the other hand, the total DDS (Dietary Diversity Score) of high school players was 3.88, significantly higher than 3.29 of middle school players. The DDS of fruit group as well as milk and dairy group were particularly low. Conclusions The results suggest that balanced diet managed by professional dieticians along with nutrition education should be implemented to improve nutrients intake and diet quality of national youth badminton players.
