Background The term, “multiple chronic diseases” (MCD), describes a patient with two or more chronic conditions simultaneously at the same time. Compared with general chronic diseases, it is linked to poorer health outcomes, more difficult clinical management, and higher medical expenses. Several existing MCD guidelines support a healthy lifestyle including regular physical activities but do not include specific exercise therapy recommendations. This study aimed to understand the prevalence and model of MCD in middle-aged and elderly South Koreans by comparing MCD characteristics with exercise habits, to provide a theoretical basis for the implementation of exercise therapy in these patients. Methods The data of 8477 participants aged > 45 years from the “2020 Korean Health Panel Survey” were used to analyze the current status of MCD in the middle-aged and elderly. The Chi-square test for categorical variables and the t-test for continuous variables. the used software was IBM SPSS Statistics 26.0 and IBM SPSS Modeler 18.0. Results In this study, the morbidity rate of MCD was 39.1%. Those with MCD were more likely to be female (p < 0.001), seniors over 65 years of age (p < 0.001), with low education level, no regular exercise behavior (p < 0.01). Chronic renal failure (93.9%), depression (90.4%), and cerebrovascular disease (89.6%) were the top three diseases identified in patients with MCD. A total of 37 association rules were identified for the group of individuals who did not engage in regular exercise. This equated to 61% more than that of the regular exercise group, who showed only 23 association rules. In the extra association rules, cardiovascular diseases (150%), spondylosis (143%), and diabetes (125%) are the three chronic diseases with the highest frequency increase. Conclusions Association rule analysis is effective in studying the relationship between various chronic diseases in patients with MCD. It also effectively helps with the identification of chronic diseases that are more sensitive to regular exercise behaviors. The findings from this study may be used to formulate more appropriate and scientific exercise therapy for patients with MCD.
Introduction Mountaineering is a very healthy reasoning sport event that focuses on intelligence and physical strength, climbing rock walls with the hands. Objective Observe the specific indicators of upper limb strength in mountaineering. Methods Athletes from a rock-climbing training team were selected as the research subjects (N=12, M=6). Before the formal experimental test, the subjects performed 30-minute warm-up exercises, including stretching and jogging. Results The negative correlation between sports performance and maximum heart rate after a 15-meter speed climb indicates that the higher the heart rate mobilized in sport, the better the exercise performance. Similarly, was observed the positive correlation between athletic performance and blood lactate at 3 minutes after a 15-meter climb, i.e., the higher the blood lactate during exercise, the worse the athletic performance. Conclusions The higher the climbing speed and the lower the blood lactate, the better the athletic performance. Thus, athletes with high training levels and solid athletic ability can achieve a higher maximum heart rate level during exercise. Evidence Level II; Therapeutic Studies - Investigating the result.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
