The purpose of this study was to investigate the relationship between the weather change and the type and level of physical activity participation of the residents registered in a local public health center in Seoul and to provide basic data on the strategy development of health promotion project and physical activity promotion program. The subjects of this study were 1,956 members aged between 30 and 65 who were enrolled in the Center for Metabolic Syndrome Management at the Public Health Center of the Seoul Metropolitan Government. The results of this study were as follows: As a result of comparing monthly physical activity level, the highest month of physical activity was in October, November and April. The highest monthly physical activity was in September, January and October. As a result of comparing the level of physical activities by season, 'high intensity physical activity per week' was significantly higher in autumn than in summer and winter(p<.001). The mean intensity of physical activity per week was significantly higher in autumn than in spring) and winter (p<.01). There was no significant difference in walking activity per week between the seasons. Among the three types of physical activity, walking is the highest physical activity and seasonal variation is the least, so it is appropriate to use it as a strategy to minimize changes in physical activity due to seasonal changes. In the future, it will be necessary to focus on the development of walking program in order to activate physical activity. 본 연구의 목적은 날씨의 변화가 지역 거주민의 신체활동 참여 형태와 수준에 미치는 관련성을 조사하여 건강증진 사업 기획 및 신체활동증진 프로그램의 중재전략 개발에 기초자료를 제공하는 것이다. 본 연구의 연구대상자는 서울특별시 산하 일개 지방정부의 보건소 대사증후군관리센터에 등록된 나이 30세에서 65세 사이의 회원 1,956명이다. 연구결과 월별 신체활동 수준을 비교한 결과 ‘신체활동높음’ 이 가장 많은 달은 10월, 11월, 4월 순으로 나타났으며, ‘신체활동보통’ 이 가장 높은 달은 9월, 1월, 10월 순으로 나타났다. 계절별 신체활동 수준을 비교한 결과 ‘주당고강도신체활동량’은 가을이 여름과 겨울보다 유의하게 높은 것으로 나타났으며(p<.001), ‘주당중강도신체활동량’은 가을이 봄과 겨울보다 유의하게 높은 것으로 나타났다(p<.01). ‘주당걷기신체활동량’은 계절간에 유의한 차이는 나타나지 않았다. 걷기는 가장 신체활동량이 높고, 계절별 편차가 가장 적으므로 계절변화에 따른 신체활동량 변화를 최소화하기 위한 전략으로 활용하는 것이 적절할 것으로 사료된다. 추후 신체활동 활성화를 위해서는 계절별 걷기 운동 프로그램 전략 개발에 대한 연구가 필요 할 것으로 판단된다.

The purpose of the study was to investigate the effects of the volume of physical activity on obesity, physical fitness and coronary risk factors among the middle-aged women. physical activity was assessed from International Physical Activity Questionnaire (IPAQ) and were categorized by health enhancing physical activity group (PG), minimum activity group (MG), and non-activity group (NG) according to the volume of physical activity. Apparently healthy middle-aged women (n=163; 52.1±8.6 yrs) participated and they were classified as PG (n=46; 5,878±3547 MET·min/week), MG (n=64; 1,678±886 MET·min/week), and NG (n=52; 456±389 MET·min/week). Also, method of the study was categorized by vigorous activity and moderate activity according to the study of WHO (2010) and Mikael Fogeholm (2006). Measurement variables were body composition, physical fitness (hand-grip, sit-up, pacer, sit & reach, shuttle run, and long jump), total cholesterol (TC), low-density lipoprotein cholesterol (LDLC), high-density lipoprotein cholesterol (HDLC), and triglycerides (TG). One-way ANOVA was used with Tukey post-hoc (p<.05). In the result, PG had significantly low percent body fat comparing with MG or NG (p=.02). And, among physical fitness variables flexibility was higher in PG than in MG (p=.03). While HDLC (p=.007) was higher in the PG than MG or NG, LDLC (p=.024) was lower in the PG than MG. TG (p=.021) was lower in the PG than MG or NG. Vigorous activity group had significantly high pacer in classification as physical activity intensity. Glucose was lower in vigorous activity group than in moderate activity group (p=.02). In conclusion, it was generally low body fat rate and coronary risk factors for middle-aged women to increased volume of physical activity of daily life and participating vigorous activity indicated that was able to keep a high fitness standard.

새 접근틀에 의한 신체활동 권고와 지침의 동향

고광욱 대한의사협회 2010 대한의사협회지 Vol.53 No.12

As new physical activity recommendations and guidelines have spread globally since 1996,scrutiny of the evolution of national physical activity recommendations and guidelines for application to the Korean medical field iare needed. Retrieving literatures and electric database confined to aerobic activity of adult. Most findings were based on the results of epidemiological and behavioral studies of physical activity and health. Most national physical activity recommendations and guidelines have a‘physical activity for health’paradigm instead of an ‘exercise for fitness’paradigm. Most stressed the health benefits of accumulation of moderate intensity of a wide variety of physical activity and the importance of the total amount rather than the specific frequency,intensity, time, or type of physical activity. Some used scientific health behavior theories. Researchbased applications of evidence based physical activity policy to Korean medical practice are suggested. Korean medical field could have initiatives in comprehensive physical activity policy in Korean health promotion if actively adopting the new physical activity for health paradigm.

Purpose There has been accumulating evidence for the preventive effect of high physical activity on cancer. However, it is still unclear which level of physical activity is associated with the decreased risk of pancreatic cancer. The purpose of current study is to assess the association between the frequency of vigorous intensity physical activity and the risk of pancreatic cancer. Materials and Methods The nationwide retrospective cohort study was conducted using the National Health Information Database. Study participants were 220,357 Koreans who received health check-up in 2009. They were divided into four groups by the weekly frequency of vigorous intensity physical activity longer than 20 minutes (group 1, no vigorous intensity physical activity (reference); group 2, 1-3 days; group 3, 4-5 days and group 4, 6-7 days). Cox proportional hazard model was used to calculate the adjusted hazard ratios (HRs) and 95% confidence interval (CI) for incident pancreatic cancer (adjusted HRs [95% CI]) according to the weekly frequency of vigorous intensity physical activity.Results For 4.38 years’ follow-up on average, 377 cases of pancreatic cancer developed. Subjects without incident pancreatic cancer had more favorable metabolic condition and higher physical activity than subjects with incident pancreatic cancer. Adjusted HRs and 95% CI indicated that only group 4 was significantly associated with the decreased risk of pancreatic cancer (group 1, reference; group 2, 1.10 [0.86-1.40]; group 3, 0.75 [0.45-1.25] and group 4, 0.47 [0.25-0.89]). Conclusion In this nationwide representative cohort study, near daily vigorous intensity physical activity showed the preventive effect on pancreatic cancer.

Purpose: Evidence suggests that long-term air pollution exposures may induce depression; however, the influence of physical ac tivity on this effect is unclear. We investigated modification of the associations between air pollution exposures and depression by the intensity of physical activity. Materials and Methods: This cross-sectional study included 1454 Korean adults. Depression was defined as a Geriatric Depres sion Scale score ≥8. Concentrations of particulate matter (PM10 and PM2.5: diameter ≤10 μm and ≤2.5 μm, respectively) and nitro gen dioxide (NO2) level at each participant’s residential address were estimated. Based on metabolic equivalents, physical activity intensity was categorized as inactive, minimally active, or health-enhancing physical activity (HEPA). Results: Each 1-part per billion (ppb) NO2 concentration increase was significantly associated with a 6% [95% confidence interval (CI), 4%–8%] increase in depression risk. In older adults (≥65 years), a 1-ppb NO2 increase was associated (95% CI) with a 4% (1%–7%), 9% (5%–13%), and 21% (9%–33%) increase in depression risk in the inactive, minimally active, and HEPA groups, re spectively. Compared with the inactive group, the minimally active (p=0.039) and HEPA groups (p=0.004) had higher NO2 expo sure-associated depression risk. Associations of PM10 and PM2.5 with depression did not significantly differ by the intensity of physical activity. Conclusion: We suggest that older adults who vigorously exercise outdoors may be susceptible to air pollution-related depression.

손장원,Sukho Lee,Minsoo Kang,신윤아,김재현 한국운동생리학회 2022 운동과학 Vol.31 No.1

PURPOSE: Regular physical activity (PA) is an effective lifestyle modification for preventing hypertension. This study aimed to analyze the optimal frequency of PA required to reduce the incidence of hypertension in the Korean population. Most Korean studies have included only small samples and limited age ranges. METHODS: The present study analyzed 16,299,865 participants aged ≥20 years (44.25±12.74 years) from the 2009 to 2012 Korean National Health Insurance Corporation Survey database. The International Physical Activity Questionnaire was used to assess the frequency and intensity of physical activity. Hazard ratios for incident hypertension were analyzed by physical activity participation, age, and sex using multivariable Cox proportional hazard models, with a non-regular physical activity group as reference. RESULTS: A total of 1,322,674 cases of incident hypertension were identified during the mean follow-up period of over 3 years. Hazard ratios for incident hypertension increased with age, with values of 50.4 and 56.1 for men and women in the older age group, respectively. Hazard ratios for incident hypertension were significantly lower in the regular PA group of middle-aged (4%) and older (7%) adults than in the non-regular PA group. The study revealed that moderate-to-vigorous-intensity PA 3-5 times/week was most effective in reducing the risk of incident hypertension in middle-aged and older adults but not in young adults. We observed no additional lowering of incident hypertension risk in the group undergoing moderate-to-vigorous PA at a frequency of 6-7 days/week compared to the 35 days/week group. CONCLUSIONS: We suggest PA at a frequency of 3-5 times/week for the prevention of incident hypertension in Korean adults.

이학권(Lee, Hak-Gweon),지준철(Ji, Joon-Chul) 한국체육과학회 2020 한국체육과학회지 Vol.29 No.2

The purpose of this study was to identify the relationship between physical activity level, self-esteem, depression and suicide thought in adolescents. Data were used for 940 high school students in six high schools in North, Central, and South. Reliability, validity test, frequency analysis, correlation analysis, and regression analysis were conducted for the results. The results are as follows. Medium intensity physical activity influenced self-esteem, and low intensity physical activity affected depression. Suicide thoughts were influenced by low and medium intensity physical activity. In addition, self-esteem and depression were found to affect suicidal thoughts. The results of this study suggest that medium- and low-intensity physical activity may be an intervention strategy for improving mental health and preventing suicide of adolescents.

International Physical Activity Questionnaire (IPAQ) was evaluated to confirm whether the instrument could be adapted to Korean middle aged women. 203 women (48.l±10.5 yrs, 154.5±16.2 ㎝, 59.3±9.6 ㎏) responded to IPAQ translated as guided and it was re-administered I week after the first test. The test-retest physical activity level of this population were 4,599±6,161 and 4,444±5,825 MET-min/week, respectively (P>0.05). The test-retest correlation coefficient was highly significant as Kappa, 0.462; Spearman, 0.566; and Pearson, 0.562 (P<0.05). When three levels of physical activity pattern (inactive, minimally active, 'HEPA active' was analyzed, those who 'minimally active' and 'HEPA active' were heavily relied on the activity intensities of both 'walking' and 'vigorous intensity'. In conclusion, IPAQ was reliable for this population. However, the average physical activity level was higher and the standard deviation of the mean was also higher than previous reports. It may have to be careful to administer IPAQ for this particular population.

이미현,장홍영 한국융합학회 2019 한국융합학회논문지 Vol.10 No.12

The purpose of this study was to the effects of exercise intensities in physical activity of 8 weeks, on fitness, blood lipid for middle school students with intellectual disabilities. Participants of the research were allocated by low-intensity(n=8, 40∼54%HRR), middle-intensity(n=8, 55∼69%HRR), and high-intensity(n=9, 70∼85%HRR) exercise groups wirelessly. For setting and maintenance of individual exercise intensity, wireless heart rate monitor(RS-400, POLAR, Finland) was used. Fitness, BDNF, and blood lipid were measured equally before participating in physical activity and 8 weeks after participation. As a result, fitness and agility of high-intensity exercise group were significantly increased than low-intensity exercise group. BDNF of high-intensity exercise group was also significantly increased than low-intensity exercise group. For blood lipid, only total cholesterol showed differences by exercise intensity group and exercise group more than middle intensity showed significant reduction. In conclusion, when giving same exercise to middle school students with intellectual disabilities, fitness and BDNF were increased the mostly in high-intensity exercise group and total cholesterol was effective from the exercise of more than middle intensity. 본 연구는 지적장애 중학생을 대상으로 8주간의 신체활동 프로그램의 운동강도가 체력, BDNF 및 혈중지질에 미치는 영향에 대하여 연구하였다. 연구참여자는 저강도(n=8, 40∼54%HRR), 중강도(n=8, 55∼69%HRR), 고강도(n=9, 70∼85%HRR) 운동집단으로 무선 할당 하였다. 개인별 운동강도 설정과 유지는 무선심박수 측정기(RS-400, POLAR, Finland)를 이용하였다. 체력, BDNF 및 혈중지질은 신체활동 프로그램 참여 전과 참여 8주 후에 동일하게 측정하였다. 연구결과, 체력은 근력과 순발력에서 고강도 운동집단이 저강도 운동집단보다 유의하게 증가하였다. BDNF도 고강도 운동집단이 저강도 운동집단보다 유의하게 증가하였다. 혈중지질은 총 콜레스테롤만 운동강도 집단에 따른 차이가 나타났으며 중강도 이상의 운동집단에서 유의하게 감소하였다. 결론적으로 지적장애 중학생들에게 동일한 운동량이 주어졌을 때 운동강도별에 따라 체력과 BDNF는 고강도 운동집단에서 가장 많이 증가하는 것으로 나타났으며, 총콜레스테롤은 중강도 이상의 운동에서부터 효과가 있음을 확인하였다.
