PURPOSE: The purpose of this study is to investigate the effects of the angles of the knee and heel-off on the muscle activity during a bridge exercise. METHODS: 15 healthy adult men and women with the balance ability and joint working range required for performing a bridge exercise participated in this study, in which $120^{\circ}$, $90^{\circ}$ and $60^{\circ}$ angles of the knee-flexion and heel-off were applied during the bridge exercise. RESULTS: Our data showed that there were significant differences in muscle activities of elector spinae and rectus abdominis when $120^{\circ}$ and $60^{\circ}$ angles of the knee were applied, of internal oblique when $120^{\circ}$ and $60^{\circ}$ were applied, and external oblique when $90^{\circ}$ and $60^{\circ}$ were applied. When heel-off was applied, there were significant differences in muscle activities of elector spinae and rectus abdominis when $120^{\circ}$ and $60^{\circ}$ were applied, of internal oblique when $120^{\circ}$ and $60^{\circ}$ were applied, and external oblique when $90^{\circ}$ and $60^{\circ}$ were applied. CONCLUSION: In this study on an application of heel-off to the bridge exercise, we showed that the effect of the angles of the knee on the muscle activities of elector spinae, rectus abdominis, internal oblique and external oblique were all similar to the regular bridge exercise, but overall muscle activities were increased with heel-off when compared with the regular bridge exercise.
Purpose: The purpose of this study was to comprehensively understand and describe the meaning of physical activity for managing menopausal symptoms in middle-aged women. Methods: This study targeted middle-aged women with menopausal symptoms who participated in regular exercise at least three times a week for more than 12 weeks. Nine participants were individually interviewed via in-depth face-to-face interviews, and participatory observation was also employed. Colaizzi's phenomenological qualitative research method was applied for analysis. Results: Participants were asked, "What does it means to participate in physical activity at this time of your life?" Fourteen codes, six themes, and three theme clusters were derived for the meaning of physical activity for managing menopausal symptoms these middle-aged women. The six themes were "reviving the exhausted body and mind," "being free from the yoke of pain," "being settled in life," "finding oneself and becoming altruistic," "striving while anticipating change," and "equipping the body and mind." The three theme clusters were "overcoming my past pain," "taking the initiative for today's life," and "moving towards new change." Conclusion: The narratives revealed that physical activity allowed women to overcome menopausal symptoms, the burden of relationships, and stress, thereby enabling them to make positive changes in their lives and have expectations for the future. Thus, physical activity was a positive force in a healthy menopausal transition for women with menopausal symptoms. The findings of this study can be used to encourage physical activity in peri-menopausal women and to develop physical activity programs for managing menopausal symptoms.
Purpose: The purpose of this study was to review the effects of physical activity on musculoskeletal outcomes in older Koreans. Methods: Experimental studies were retrieved from the search engines (PubMed, CINAHL, PsycINFO, Cochrane, RISS, KISS, and KoreaMed). The selected studies for analysis were 27 articles of musculoskeletal outcomes (gait, muscle strength, flexibility, balance, grip strength, endurance, body fat, and weight) from 515 articles. Results: The most common type of physical activity was a resistance exercise. There were significant improvements in gait (71.4%), muscle strength (86.7%), flexibility (63.6%), balance (72.2%), grip strength (71.4%), endurance (71.4%), body fat (57.1%), and weight (28.6%). The activity programs that apply over 150 minutes a week showed greater improvement of 69.5% than 65.0% from those did not meet the guidelines totally. Conclusion: Based on the review, we conclude that regular physical activity in the elderly may improve the musculoskeletal outcomes. To be more effective programs, it is necessary to meet the guidelines of 150 minutes a week or 30 minutes of moderate-intensity activities on 5 days per week for the elderly.
Objectives : The aim of this study was to investigate the prevalence of metabolic syndrome and the association between lifestyle factors and the risk of metabolic syndrome in Korean adolescents. Methods : The metabolic syndrome was defined with ${\geq}$ 3 metabolic abnormalities using the age-modified criteria of the Adult Treatment panel III specified by National Cholesterol Education Program in adolescents aged 12 to 18 years who have participated in the Kroean National Health and Nutrition Examination Survey in 1998(n=936) and 2008(n=620). Physical activity and dietary intakes were assessed. Results : The overall prevalence of metabolic syndrome in Korean adolescents declined over 10 years (P < 0.01). Adolescents engaging regular exercise significantly increased over 10 years (P < 0.001). Physically activity was associated with a lower risk of metabolic syndrome (P < 0.001). Dietary intake patterns were not associated with a risk of metabolic syndrome. Conclusions : The prevalence of metabolic syndrome among Korean adolescents declined over 10 years which may be in part due to the increased regular physical activity. The risk of metabolic syndrome is lower in individuals who are physically active.

The purpose of this study is to identify the quality of life (QOL) and factors influencing the QOL in middle-aged and elderly cancer patients. Among the 2019 data of the Korea Health Panel, data from 498 adults over the age of 40 who were diagnosed with cancer by doctors were analyzed. As a result of the study, the mean QOL of middle-aged cancer patients was 0.90 (±0.09) and that of elderly cancer patients was 0.86 (±0.12). The QOL of middle-aged cancer patients was significantly higher than that of elderly cancer patients. Factors influencing the QOL of middle-aged cancer patients were subjective health status, anxiety, suicidal ideation, and bedridden status. Factors influencing the QOL of elderly cancer patients were subjective health status, bedridden status, economic activity, education level, regular physical activity, stress, and age. In order to improve the QOL of middle-aged and elderly cancer patients, along with interest in the QOL of middle-aged and elderly cancer patients, it is necessary to develop an age-specific intervention program, such as reducing anxiety and suicidal ideation for middle-aged cancer patients, and improving regular physical activity and reducing stress for elderly cancer patients.
Purpose: The purpose of this study was to review the relationship between physical activity and cardiovascular outcomes in the Korean elderly. Methods: Experimental studies were located using PubMed, CINAHL, PsycINFO, Cochrane, RISS, KISS, and KoreaMed. The selected studies for analysis were 20 articles of cardiovascular outcomes (total cholesterol, triglyceride, high density lipoprotein (HDL), low density lipoprotein (LDL), blood pressure, and pulse rate) from 515 articles. Results: One-group pretest-posttest design was the most common. The main physical activity was an aerobic exercise. Five of 14 studies reported a significant improvement of total cholesterol. Four of 14 studies found relationship between exercise and triglyceride. Eight of 12 studies reported a significant improvement of HDL, whereas 3 of 9 studies reported a significant improvement of LDL. In over 60% of selected studies, reported significant improvement of blood pressure. Conclusion: Based on the review, it suggests that regular physical activity of the elderly may improve cardiovascular outcomes.
This study has analyzed the association of physical activity and television watching time with obesity in 30-50 aged women from middle income town in Busan city area. Data were obtained using a questionnaire, including information about physical activity, TV watching time and health habit; social data regarding educational level and monthly income; family history of chronic condition. Height and weight were measured. Outcome variable was obesity, defined as a body mass index 25 kg/m$^2$ or greater. Odds ratios (OR) for obesity were estimated by multivariate logistic regression, and interpreted as a relative risk of obesity. The prevalence of obesity was 11.8%. The mean BMI of obese women was 26.9 kg/m$^2$. The OR of obesity was higher in subject of 40s than 30s. Subjects who had higher educational level presented lower OR than those of elementary or middle school education. Family income was not associated with obesity. Women having a family history of chronic condition had higher risk of obesity than those who did not have it. The OR was lower in active people at work (OR = 0.51; 95% CI = 0.26 - 0.98) than in inactive ones, and the ORs associated with regular exercise or activity at leisure time were not statistically different. However, subjects watching TV $\geq$ 3.5 hr/day showed higher OR (OR = 2.34; 95% CI = 1.16 - 4.74), compared with those watching TV $\geq$ 1.5 hr/day. Association of the joint classification of physical activity variables with obesity was estimated. The highest relative risk of 5.99 was in women in physically inactive at work and high category of TV watching ($\geq$ 3.5 hr/day). Even in women in active at work, the watching TV $\geq$ 3.5 hr/day made them have the high OR (OR = 2.44; 95% CI = 1.03 - 5.77). And at each time level of TV watching, the increasing activity level at work was associated with lower OR for obesity. These findings suggest that both TV watching time and physical activity at work were related to obesity in adult female, each with independent effects on obesity. TV watching time seems to be a significant factor that could partly evaluate the energy expenditure.
Objective: Patients with chronic obstructive pulmonary disease (COPD) may experience reduced physical activity and quality of life (QoL) due to decreased pulmonary function. The purpose of this study was to investigate the level of pulmonary function, physical activity, and QoL of COPD patients. Design: Cross-sectional observational study. Methods: This study examined the published data of the Korea National Health and Nutrition Examination Survey in 2015-2019. Among 39,759 subjects who participated for 5 years, data from 151 patients diagnosed with COPD were analyzed separately. For the pulmonary function, the results of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV6, forced expiratory flow 25-75%, and peak expiratory flow were observed. Physical activity was identified as frequency and duration. For the QoL, EQ-5D-3L evaluation results were examined, and the frequency and index of the Korean version were investigated. Results: In pulmonary function, all variables were found to be lower than age and weighted matched normal values. COPD patients showed to perform very low levels of high/medium physical activity and sitting time was confirmed to be more than 8 hours a day. In QoL, it was found that the highest reporting rate of some problems was the "pain and discomfort" and "mobility". Conclusions: It was found that COPD patients showed that the prevalence of circulatory disease was relatively high, lowered pulmonary function, and QoL. These can be improved through regular physical activity, and it is thought that this can be achieved through optimization of pulmonary rehabilitation.

This study involved a secondary analysis of 2016 Korean National Health and Nutrition Examination Survey data to identify the relations between metabolic syndrome, physical activity, and dietary patterns in Korean adults. The ${\chi}^2$-test, t-test, and logistic regression analysis of complex samples were conducted on the data of 3,352 subjects aged 19 to 64 years with metabolic syndrome. The prevalences of metabolic syndrome among men and women were 29.7% and 16.7%, respectively. In men, the high physical activity group showed a 0.8-fold increase in the likelihood of metabolic syndrome (OR=0.8, p=.038), and higher fat intake increased the risk of metabolic syndrome 0.98-fold (OR=0.98, p=.007). In women, the high physical activity group showed a 0.7-fold increase in the likelihood of metabolic syndrome (OR=0.71, p=.034), higher carbohydrate intake increased the risk of metabolic syndrome by 1.03-fold (OR=1.03, p<.001), and that higher protein and fat intakes reduced the risk by 0.96-fold (OR=0.96, p=.009) and 0.95-fold (OR=0.95, p<.001), respectively. The study shows that to meet the challenge presented by the increasing prevalence of metabolic syndrome, efforts are needed to screen for adults at risk of the metabolic syndrome by regular physical examination and to develop and provide intervention programs that involve regular high intensity physical activity and controlled carbohydrate, protein, and fat intakes.
The purpose of this study was to confirm that regular physical exercise habit and calcium intake play a role reducing the risk of cardiovascular diseae, particularly to confrim that regular exercise is important in reducing serum lipid levels. Subjects were classified into regular exercise group(more than 3 times/wk, more than 30 min per exercise) and non-regular exercise group. A convenient frequency method was used to assess the nutritional intake of subjects. Anthropometric measurement such as bodyweight and hight, and blood pressure were measured. There was no significant difference between nonexercisers and exerciser in energy intake, calcium intake and blood lipid levels. The strength of frequency of exercise may not by adequate to modify lipid profiles in premenopausal woman with normal lipid level, Although we found no significant difference in blood lipid levels, this result does not imply there are no benefits of exercise subjects. There were no signigicant correlations between age or weight with blood lipids in regular exercise group, while there were significant positive correlations between age of weight with blood lipids in non-regular exercise group. The levels of serum cholesterol, and triglyceride, blood pressure and atherogenic index increased with age in nonexercise women, Especially, atherogenic index was lower in regular exercise group. The blood pressure in nonexercise group was significantly higher than that in regular exercise group There was a highly significant negative correlation between calcium intake and blood pressure in nonexercise women, There was a highly significant negative correlation between calcium intake and blood pressure in nonexercise women. The results suggest that increased habitual physical activity and calcium intake may have desirable effects on serum lipid levels and blood pressure in premenopausal women.(Korean J Nutrition 34(1):62-68, 2001)
