This study was conducted to evaluate the effect of regular exercise and other relating factors on the activities of erythrocyte antioxidant enzymes and plasma total radical-trapping antioxidant potential (TRAP) in 61 healthy male college students. The study population were divided in two groups ; small amount of exerciser (exorcise time less than 30min/d) and moderate amount of exerciser (exorcise time more than 30min/d) according to their physical exercise habits measured by a questionnaire. Dietary intake of vitamin C and vitamin E, Plasma lipid Profiles, erythrocyte superoxide dismutase(SOD), glutathione peroxidase(GSH-Px) and catalase activities, as well as plasma TRAP levels were determined. Plasma TRAP level was significantly higher in moderate amount of exercisers than that in small amount of exercisers. No significant differences were observed in erythrocryte SOD, catalase and GSH-Px between the two groups. Mean exercise time was positively correlated with the plasma level of TRAP significantly, and amount of alcohol consumption was negatively correlated with the erythrocyte SOD activity, Dietary vitamin C and I intakes did not correlated with either erythrocyte enzyme activities or plasma TRAP levels. There were positive correlations between plasma HDL-cholesterol, and erythrocyte GSH-Px or plasma TRAP levels. Plasma vitamin C concentrations was negatively correlated with plasma TRAP levels and erythrocyte SOD activity, however plasma vitamin C concentration was positively correlated with erythrocyte GSH-Px activity, The results would suggest that regular moderate exercise, nonsmoking, high HDL-cholesterol and high plasma vitamin E concentration enhance antioxidant defences against reactive oxygen species and may increase the likelihood of a healthier life span.

Purpose: In order to examine whether daily physical activity (DPA) can be considered the same as a regular exercise (RE) in patients with Heart Failure (HF), we examined the relationship between RE and DPA, and we explored the relationship of RE and DPA with exercise capacity and quality of life (QOL) in patients with HF. Methods: This cross-sectional, correlational study utilized pretest data (N=136) of a long-term intervention study. Data of the parent study were collected from May 1st to September 26th, 2013. Measures included questions about regular exercise, International Physical Activity Questionnaire, a 6-Minute Walk Test (6MWT), and the Kansas City Cardiomyopathy Questionnaire (KCCQ). The data were analyzed using descriptive analysis, Chi-square test, and ANOVA using the SPSS 21.0 program. Results: There were inconsistencies in measures between RE and DPA. About 42.0% of the participants engaging in health enhancing physical activity did not consider themselves to be regular exercisers. Depending on the levels of RE and DPA, significant differences in 6MWT and QOL were observed. Conclusion: RE is more likely to be related to the health status of patients with HF. Deliberate assessment and cautious interpretation of DPA in patients with HF is needed.

Purpose: The aim of this study was to examine the effects of an Advanced Practice Nurse (APN)-led self-management program on cardiovascular health status among Korean women at risk of developing or progressing cardiovascular disease. Methods: This pilot study used one-group pre- and post- test experimental design. At health fairs in a community, 30 women who had one or more risk factors for metabolic syndrome were recruited and agreed to participate in the study. A total of 25 women completed the study. The intervention consisted of weekly follow-up calls and self-monitoring diary after an hour of individual counseling regarding risk factors, fast walking, and healthy diet tailored to the participants' needs. Physical activity was assessed with the World Health Organization International Physical Activity Questionnaire and a pedometer. Results: Participants showed statistically significant improvements in blood pressure, body mass index, levels of triglyceride, total cholesterol and low density lipoprotein, numbers of metabolic syndrome factors, and the 10-year CV risk estimate after one month of concentrated intervention. In addition, their physical activity behavior significantly improved after the intervention. Conclusion: This APN-led self-management program targeting modifiable risk factors by offering tailored counseling and concentrated support during the transition might be effective in preventing progression to the cardiovascular disease.

PURPOSE: This study aimed to utilize the International Classification of Functioning, Disability, and Health (ICF) tool to identify a problem list and explore intervention effects using proprioceptive neuromuscular facilitation (PNF) for improving the crosswalk performance of patients who have undergone a bilateral hip arthroplasty. METHODS: The subject of this study was a 43-year-old male who had undergone a bilateral hip arthroplasty. To address the subject's functional status, a clinical decision-making process was carried out in the order of examination, evaluation, diagnosis, prognosis, intervention, and outcome. Patient information during the examination was collected using the ICF core set. The evaluation involved listing the items of each problem using the ICF assessment sheet and identifying the interaction between activity limitations and the impairment level. The diagnosis explicitly described the causal relationships derived from the evaluation using ICF terminology. The prognosis presented activity goals, body function, and structured goals in terms of the activity and participation levels that needed to be achieved for an individual's functional status. The intervention approached problems through the four components of the PNF philosophy, namely basic principles and procedures, techniques, and patterns, in an indirect-direct-task sequence. Results were compared before and after the intervention using the ICF evaluation display. RESULTS: The results of the study showed that the primary activity limitation, which was the walking time across the crosswalk, showed improvement, and the trunk's counter rotation and the weight-bearing capacity of both the lower limbs, which were impairment level indicators, were enhanced. CONCLUSION: This study suggests that PNF intervention strategies will serve as a positive approach for improving crosswalk walking in patients with bilateral hip arthroplasty.

This study was conducted to investigate the effects of weight control program on food habits, eating behaviors and life habits in obese elementary school children. The program consisted of nutritional education, physical exercise and behavioral therapy was conformed for 10 weeks. Participants of the study involved 41 obese children and their parents. There was significant difference in waist circumference (p < 0.05) and children's body fat % significantly decreased from 35.8% to 33.0% (p < 0.01) after program. There was significant increase (p < 0.05) in HDL-cholesterol, 47.8 (mg/dL) to 53.6 (mg/dL) after weight control program. Food habits and eating behaviors of obese children were showed positively changes but there were no significant differences after program. Regularity of having breakfast and amount of meal under the stress condition were not significantly different after program. The levels of physical activity of obese children were significantly increased from 1.40(hr) to 1.74(hr) per day (p < 0.05). But there were no significant changes in spending hours of watching television and playing computer games. Food habits, eating behavior and physical activity showed significant correlations to weight control. These results suggest that the body weight control program for obese children including nutrition education, physical exercise and behavioral therapy may be effective to improve their food habits, eating behaviors and life habits. Nevertheless we need a more concentrating program to improve life habits such as physical activity and watching television.

PURPOSE: To investigate the validity of a smartphone application for post-stroke daily living activity management based on an evaluation by users and experts. METHODS: The study design adhered to the analysis, design, development, implementation, and evaluation ADDIE (Analysis-Design-Development-Implement-Evaluation) model. We downloaded the application onto the smartphones of 33 users and 30 experts, taught them how to use it, and asked them to use the application for four weeks. The users' daily lives before and after using the application were compared based on the K-MBI (Korean Version of Modified Barthel Index) to evaluate the usability of the application. For the expert group, we investigated the content validity and reliability of the application and evaluated the usability of the application. Data were analyzed using the SPSS 21.0 software. Users' general characteristics and experts' evaluation scores were analyzed using descriptive statistics. Content validity was tested using the content validity index (CVI), and reliability was tested with Cronbach's alpha. Users' K-MBI scores before and after using the application were compared with the paired sample t-test. RESULTS: Users gave an average rating of 2.93 out of 4 for the application for managing the daily lives of stroke patients, while experts gave an average score of 3.14. With regard to the K-MBI scores, only the dressing score improved significantly (p<.005) after using the application, and scores for other categories slightly improved but not to significant levels. CONCLUSION: The results of this study suggest that the STROKECARE application is usable and could help stroke patients manage their daily lives.

The purpose of this study was to assess the daily steps, physical activities and activity coefficient of the elementary school children in the rural area. Body weight, height and daily steps were measured and one-day activity diaries were collected by interviewing children. The average age of the subjects was $9.96{\pm}1.02$ years. Average height, weight, obesity index, body fat and muscle of subjects were $136.2{\pm}8.9cm,\;35.2{\pm}8.5kg,\;99.6{\pm}18.8%,\;22.9{\pm}8.5%\;and\;35.8{\pm}6.0%$, respectively. The average daily steps of the subjects was 17,584 and daily steps (19,314) of 3rd grade students was significantly higher than that (15,712) of 5th grade children. But there was no significant difference in daily steps and activity coefficients between boys and girls. Daily steps (23,347) of exercise group showed the significantly higher than that (16,144) of non-exercise group. Gender and grade of subjects did not have significant influence on activity coefficients, but there was a significant difference in activity coefficient on weekdays between the exercise group ($1.82{\pm}0.30$) and non-exercise group ($1.50{\pm}0.21$). Analysis of variance revealed stronger associations between daily steps and body fat (%) than between daily steps and BMI. Daily steps showed significant negative correlation with body fat (%) measured using two methods r=-0.321 and r=-0.365, respectively. Activity coefficient was significantly correlated (r=0.436) with daily steps, thus increasing daily steps cm prevent and treat childhood obesity by increasing the energy expenditure. The higher activity coefficients (weekday 1.56, weekend 1.53) of the subjects was caused by the fact that rural students spent more time outside and enjoyed stronger activities than urban students. The results of this study can be used to estimate energy requirements for Korean children based on exercise levels and living areas.

This study aimed to compare movement patterns of shoulder joints between the right and left symmetry in stroke patients and control subjects. This study proposes use of the voluntary response index (VRI) calculated from quantitative analysis of surface electromyographic (sEMG) and motion data recorded during voluntary movement as a feeding task. The VRI is comprised of two numeric values, one derived from the total muscle activity recorded for the voluntary motor task (magnitude), and the other from the sEMG distribution across the recorded muscles with the similarity index (SI). Five stroke patients and five age-matched healthy controls were recruited. Feeding motion was performed using the provided spoon five times with rests taken on a chair in between tasks. EMG data were digitized and analyzed on the basis of the root mean square (RMS) envelope of activity. The average amplitude of responses was calculated. Responsiveness and clinically meaningful levels of discrimination between stroke patients and control for EMG magnitude and SI were determined. The similarity index of the results from two successive examinations of both sides apart for stroke patients and control subjects were .86 and .95 in motion analysis and .84 and .99 in electromyographic analysis. The SI of sEMG data and motion data was significantly correlated in stroke patients. The data suggest that SI is a sensitive program for comparing and analyzing the symmetry of muscle activity and motion in both sides. This analysis method has a clinical value in grading muscular activity and movement impairment after brain injury.
