LDA 분석에서는 생리적 회복과 훈련⋅경기 요인, 심리⋅정서적 회복의 세 가지 주제가, CONCOR 분석에서는 ‘생리적 회복 및 경기력 관리’, ‘훈련 및 경기 관리’, ‘심리적 요인’, ‘부상 관리 및 회복탄력성’ 등 네 가지 군집이 나타났다. 이는 국내 연구가 단편적 접근을 넘어 다차원적⋅통합적으로 확장되고 있음을 시사한다. 향후 연구는 종목별 회복 지표와 심리 회복 측정 도구의 현장 적용, 국제적 자료를 포함한 다층적 연구가 필요하다.; This study analyzed 170 articles on athlete recovery published in Korean academic journals between 2010 and 2024 using text mining techniques to identify research trends and future directions. Methods included yearly and society-based distributions, word frequency and TF-IDF analyses, semantic network analysis, LDA topic modeling, and CONCOR analysis. Results showed that 65% of the articles were published in the past five years (2020–2024), indicating growing academic interest. Key terms such as “recovery,” “resilience,” “heart rate,” and “lactate” highlighted both physiological and psychological themes. LDA revealed three topics—physiological recovery and training, game-related factors, and psychological–emotional recovery—while CONCOR produced four clusters: physiological recovery and performance management, training and game management, psychological factors, and injury management with resilience. These findings demonstrate a shift in domestic recovery research from fragmented approaches toward multidimensional and integrative perspectives. Future studies should emphasize practical applications, such as sport-specific recovery indices and field use of psychological recovery tools. This study is limited by its focus on domestic literature and traditional physiological indicators, excluding molecular and genetic-level approaches. Broader, multilayered analyses incorporating international data are therefore needed. 2025-09-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/198087 Title: Overlapping and Distinct Physical and Biological Phenotypes in Pure Frailty and Obese Frailty Authors: Ji, Fujue; Park, Ji Hyun; Rheem, Hyeonseung; Kim, Jong-Hee Abstract: Background: Pure frailty and obese frailty are common types of frailty syndrome. However, the overlapping and distinct characteristics between pure frailty and obese frailty remain unclear. This study aims to reveal the overlapping/distinct physical and biological phenotypes of pure frailty and obese frailty, providing theoretical support for their prevention, diagnosis, and treatment. Method: Mice were fed either a normal or high-fat diet and assessed at 20 months of age. They were assigned to one of the four groups: control, obesity, pure frailty, and obese frailty. Grip strength, walking speed, physical activity, endurance, and body weight were measured to determine pure frailty and obese frailty. Physical and biological phenotypes were assessed. Results: Distinct physical phenotypes were observed between pure frailty and obese frailty in terms of body weight, lean mass, fat mass, fat mass in tissue, grip strength, endurance, and physical activity, while walking speed overlapped. In biological phenotypes, levels of Smad2/3, FoxO3a, P62, LAMP-2, and cathepsin L expression were distinct, while AKT, p-AKT, mTOR, p-mTOR, p-Smad2/3, p-FoxO3a, Beclin-1, ATG7, and LC3 overlapped. Conclusion: Distinct physical phenotypes observed in obese frailty are primarily attributable to the effect of obesity, with further impairment of muscle function resulting from the combined effects of frailty syndromes and obesity. Pure frailty and obese frailty share overlapping biological phenotypes, particularly in the regulation of muscle protein synthesis. Moreover, the interaction between obesity and frailty syndromes gives rise to both overlapping and distinct biological phenotypes, especially in the regulation of specific degradation signaling proteins. 2024-11-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/212701 Title: Exercise effects on neuropsychiatric symptoms and quality of life in mild cognitive impairment: a systematic review and meta-analysis Authors: Chen, Liang; Kim, Sung Min Abstract: Background: Exercise is considered as a cost-efficient option for individuals with mild cognitive impairment (MCI). Although the potential benefits of exercise for improving cognitive function are recognized, its impact on neuropsychiatric symptoms (NPS) and the quality of life (QoL) in individuals with MCI remains unclear. Objective: This study aims to investigate the effects of exercise interventions on NPS, including depression, anxiety, sleep disorders, and the quality of life in individuals with MCI. Results: There were 17 randomized controlled trials (RCTs) involving 1,575 participants were included. The findings indicate a small but significant positive effect of exercise on depression (standardized mean difference [SMD] = -0.47, 95% confidence interval [CI]: -0.73 to -0.21), but the quality of the evidence is low. Mind-body exercises were relatively more effective in alleviating depression. No significant improvements were observed in sleep disorders (SMD = -1.27, 95% CI: -2.80 to 0.26). Exercise improved anxiety in one study but had no effect in the other. It also improved quality of life in seven studies, with two showing no effect. Conclusion: The findings suggest that exercise, particularly mind-body exercises, can improve depression in individuals with MCI. However, the effect of exercise on anxiety, sleep disorders, and quality of life is still uncertain, necessitating additional research. These findings underscore the significance of integrating customized exercise programs in managing MCI to boost quality of life and mitigate NPS. 2024-10-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/210502 Title: 운동 중재가 경도인지장애 노인의 우울증에 미치는 효과 : 체계적 문헌고찰과 메타분석 Authors: 진량; 김성민 Abstract: Exercise is recommended as an economical and effective intervention for older people with Mild Cognitive Impairment (MCI). However, the effects of exercise intervention for improving depression symptoms in patients with MCI remain controversial. This study aimed to examine the effects of exercise on depression symptoms in older people with MCI. We conducted a search for Randomized Controlled Trials (RCTs) comparing the effects of exercise on depression with non-exercise interventions in participants aged over 60 years with MCI. The search was performed across 10 related multiple databases at home and abroad and the ClinicalTrials.gov platform up to February 2024. Fourteen RCTs were included in this review. Meta-analysis results indicated a small positive effect of exercise on measures of depression (SMD = -0.47, CI: -0.73 to -0.21), with mind-body exercise being more effective than other types of exercise in improving depressive symptoms in elderly individuals with MCI (SMD= -0.40 95% CI: -0.69 to -0.10). Furthermore, exercise interventions conducted three times a week for 40 minutes each session over a 24-week period were found to be relatively more effective in alleviating depression in MCI patients. Based on these conclusions, exercise professionals and physicians should tailor exercise plans to the individual circumstances of each patient to optimally improve depressive symptoms in elderly individuals with MCI. 2024-08-01T00:00:00Z
