Purpose: Adolescent obesity is a growing problem. This study examined the relationships between different types of physical activity and obesity in male and female middle and high school students. Methods: This study used the Korea National Health and Nutrition Examination Survey data of 2007. The study included 282 male and female middle and high school students who completed health survey questionnaires regarding physical activity. Physical activity was measured with vigorous and moderate activity and walking. BMI was used as an obesity indicator. Analyses were done using descriptive statistics, ANOVA, and chi-square test. In addition, multiple logistic regression were conducted to investigate the relationship between physical activity and obesity when adjusting for covariates. SAS/WIN 9.1 was used. Results: Boys spent more days in vigorous and moderate physical activity than girls (p for vigorous activity: <.001, for moderate activity: <.001). There was no significant difference in walking activity between boys and girls and between middle and high school students. Only days spent in vigorous activity was significantly higher in middle school student compared with high school students (p=.013). According to the relationship between physical activity and obesity, moderate physical activity was significantly related to BMI for high school boys (p=.041). However, when adjusting for age, sex, school, parental income, daily caloric intake, physical activity was not significantly related to obesity. Conclusions: The results showed that male and female middle and high school students spent not enough days in doing low moderate and vigorous physical activity. Thus, this strengthens the need to increase physical activity level in these populations. In spite of non-significant relationship between physical activity and obesity from multivariate analysis, increasing moderate physical activity for high school boy could be effective to prevent and manage obesity, since significant difference between moderate activity and obesity in this population.

Purpose: To identify the effect of breathing training on the physical function and psychological problems in patients with chronic stroke. Methods: In total, 26 patients with chronic stroke were randomly assigned to one of two groups: the experimental group, who underwent breathing training and neurodevelopmental treatment, and the control group, who underwent neurodevelopmental treatment (13 patients per group). Physical function was evaluated using the balance and Activities of Daily Living (ADL). Psychological problems were assessed using the Depression. Balance was measured using the Berg Balance Scale (BBS). ADLs were measured using the Modified Barthel Index (MBI). Depression was measured using the Beck Depression Inventory (BDI). The BBS, MBI, and BDI were recorded before and after the 4-week treatment. Results: As a result of comparison within groups, the experimental and control group showed significant difference for BBS, MBI and BDI after the experiment (p<0.05). In comparison between two groups, the experimental group showed more significant difference in BBS, MBI and BDI than the control group (p<0.05). Conclusion: This study showed that breathing training was effective improvement physical function, and psychological problems in patients with chronic stroke.

The purpose of this study was to find the relationship between standing posture biomechanics and physical fitness in the elderly. Physical fitness variables and postural variables for 227 (140 women and 87 men) elderly individuals were tested. Physical fitness tests (Korean Institute of Sports Science, 2012) included 3m sit, walk, and return, grip test, 30 second chair sit and stand, sit and reach, figure 8 walks, and 2 minute stationary march. Postural biomechanics variables included resting calcaneal stance position (RCSP), shoulder slope, pelvic slope, knee flexion angle, leg length difference, thoracic angle, and upper body slope. In statistical analysis, multiple regression was conducted by using stepwise selection method via SAS (version 9.2). Analysis for both men and women revealed significant relationships between physical fitness and age, upper body slope, knee flexion angle, leg length difference. Pelvic and thoracic angle were only related to figure 8 walking and sit and reach in women, while RCSP and shoulder slope had no relationship with any physical fitness variables.

Purpose: The aim of this study was to determine the effects of lower rib cage lateral expansion limitation on the maximal inspiratory and expiratory pressures and on abdominal muscle activity during maximal respiratory breathing in healthy subjects. Methods: Fifteen healthy male subjects voluntarily participated in this cross-sectional study. During maximal breathing, maximal inspiratory and expiratory pressures were measured, and abdominal muscle activity was determined with using surface electromyography. Also, the measurement was repeated with using a non-elastic belt to the lower rib cage for limiting of lateral expansion. A Wilcoxon signed-rank test was performed for obtaining the statistical difference with a significance level of 0.05. Results: The findings of this study are as follows: 1) There were no significant differences in maximal inspiratory and expiratory pressure with and without lower rib cage lateral expansion (p>0.05), 2) There was no significant difference in abdominal muscle activity during the maximal inspiratory phase (p>0.05). However, right external oblique muscle activity decreased significantly during maximum exhalation with lower rib expansion limitation (p<0.05). Conclusion: The results of the current study indicate that a non-elastic belt was effective in decreasing right external oblique muscle activity during forced expiratory breathing in healthy subjects.

This study is attempt to submit a basic material to help the efficient nursing management which supports and to understand the alienation which they percieve social-psychologically and physical aging bringing about the phf·sical powerlessness, to understand the old people in hospitals and in community and should build up their health. The data collection of the study which has been done on Sept. 7 to Sept. 20, 1986 is objected to 300 people of 65 years old of age or more of male and female who are staying at home. Analysis of the Data was done by use of percentage, t-test, ANOVA and Pearson Correlation Coefficients. The results of study are summerized as follows: 1. According to each age group of old people(p= .0008), family living together concreteness (p=.0000), the level of education (p=.0020), how much they are participating in leisure activity (p=.0001), whether they have mate or not (p=.0000), whether they have religion or not (p=.0000), the level of alienation showed difference statistically. Also, according to sex (p=.4315), whether they have income or not (p=.1197), the level of alienation did not show any difference statistically. 2. According to each age group of old people (p=.0000), family living together concreteness (p=.0060), the level of education (p=.0000), sex (p=.0000), whether they have mate or not (p=.0000), whether they have religion or not (p=.0067), whether they have income or not (p=.0000), the level of physical aging showed difference statistically. Also, according to how much they are participating in leisure activity, the level of physical aging did not show any difference statistically (p=4879). 3. The level of alienation and physical aging in old people had positive correlation (r=.5436, p<.001). From the above result, the level of social, psychological alienation and physical aging showed high for the old who had no mate, no religion, low in their educational level, living separately' with the family and for those who do not participate much in the leisure activities, The old people who feel the social, psychological alienation can expedite the physical aging and physical aging can be result from social psychological loneliness and alienation. Therefore, for the successful aging of the old people in the community with these weak points, we should provide them with physical and emotional, psycho-logical support and care in the basis of understanding in socialization process and the character of the physical functional change.
