OBJECTIVES This study was conducted to figure out the effects of kendo training on the activity of brainwaves by analyzing changes in brainwaves during chudan-no-kamae and three-movement-striking, which are basic movements of kendo, in elementary school students who undergo kendo training and comparing left and right side brainwave activities to find out differences. METHODS This study was conducted with 29 male elementary school students living in K City who were experts in kendo with a career as an athlete or a kendo training period not shorter than six months. The brainwave activity was measured by measuring and analyzing brainwaves at eight regions at the prefrontal lobe, the frontal lobe, the temporal lobe, and the occipital lobe using brainwave measuring equipment. Brainwaves were measured for 5 minutes in a sitting position in a stable state and were also measured for 5 minutes after 15 minutes of the chudan-no-kamae movement, which is aiming at the opponent with the point of the sword while moving along eight moving lines of the opponents, and for 5 minutes after 15 minutes of three striking movements. RESULTS Alpha waves showed higher brainwave activity during the stable state than during the kendo movements (three striking movements, chudan-no-kamae) while SMR, M-beta, and H-beta showed higher brainwave activity after kendo movements than during the resting state. The asymmetry between the left and right sides increased after the movements compared to during the resting state. CONCLUSIONS These results are considered attributable to kendo training that partly increased their concentration thereby increasing brainwave activity. However, it is unclear that kendo training will be helpful for concentration through physical activities and brain activity in this study. Therefore, further study should be conducted with the measurement of factors related to emotional aspects, concentration, and brainwaves according to kendo training.

OBJECTIVES The purpose of this study is to compare the difference in the prevalence of hyperlipidemia according to the level of physical activity in adults, and to compare the difference between annual personal medical expenses, hospitalization, emergency and outpatient use depending on the level of physical activity for hyperlipidemia patients. METHODS The 2018 Korea medical panel data was used (14,489 adults and 2,559 Hyperlipidemia). Physical activity was measured with short form of IPAQ and converted to MET-minutes per week. The days of hospitalization, and personal medical expenses were compared, and frequency analysis, logistic regression, ANOVA and chi-square were performed. RESULTS The prevalence of hyperlipidemia based on the inactive group were decreased both minimally active group (OR = 0.94) and the active group (OR = 0.74, p

OBJECTIVES The purpose of this paper is to analyze the differences in the prevalence of diabetes mellitus, in relation to the physical activity grade and to compare differences in, personal medical expenses, the days of hospitalization, inpatient, outpatient and emergency. METHODS The medical panel data of Korea used in 2016, with a total of 13,523 adults and 1,404 diabetes mellitus patients. Physical activity level measured with IPAQ questionnaire, and displayed as MET-minutes per week. The days of hospitalization, personal medical expenses, using of inpatient, outpatient and emergency investigated, and frequency analysis, logistic regression, ANOVA, and Chi-square performed. RESULTS The prevalence of diabetes mellitus based on inactive group was reduced both minimally active group (odds ratio [OR] = 0.81) and active group (OR = 0.73, p

OBJECTIVES The purpose of this study is to compare the differences in the prevalence of hypertension in relation to the physical activity grade and to analyze differences in the days of hospitalization of hypertension patients, drug expenses and personal medical expenses. METHODS The Korea medical panel data was used in 2016, with a total of 13,276 adults and 3,470 hypertension patients. Physical activity was measured with IPAQ and converted to MET-minutes per week. The days of hospitalization, monthly average for hypertension drug expenses, and personal medical expenses were investigated, and frequency analysis, logistic regression, and ANOVA were performed. RESULTS The prevalence of hypertension based on the inactive group were decreased both minimally active group (odds ratio [OR] = 0.89) and the active group (OR = 0.77, p
