Background : Respiratory muscle weakness has serious clinical consequences. Vital Capacity is the volume of air that is normally exchanged in a single breath. It varies widely with pulmonary health and overall fitness. Purpose : The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of Kinesio taping and balloons blowing. Methods : Twenty-one non-smokers were participated in this research and these subjects were randomly assigned into three groups; a balloons blowing group(n=7), a Kinesio taping group(n=7), and a balloons blowing and Kinesio taping group(n=7). This experiment was done from June 22, 2009 to July 5, 2009. In order to measure the VC variation effects of Kinesio taping, balloons blowing, and both intervention, an windmill type spiropet was used. The collected data were analyzed statistically by using a paired t-test and ANCOVA. Results : The results of this study were as follows; 1) In the case of balloons blowing, there was a significant difference, 3.35% increase of VC, between before and after 2 weeks experiments(p<.01). 2) In the case of Kinesio taping, there was a significant difference, 11.66% increase of VC, between before and after 2 weeks taping intervention(p<01). 3) In the case of both balloon blowing and Kinesio taping, there was a significant difference, 15.84% increase of VC, between before and after 2 weeks both interventions(p<.01). 4) After 2 weeks experiment, the improvement of VC was shown a significant difference with intergroup(p<.05). Conclusion : From these results, it was revealed that balloons blowing or Kinesio taping, or both interventions were effective to improve VC of healthy adults.

This study analyzed the relationship among swimming experiences, swimsuit selection criteria, swimsuit purchase satisfaction level, and the physical self-concept of female consumers. This study was based on a descriptive survey method using a questionnaire. The survey was conducted from June 15 through July 20, 2012, and the sample consisted of 330 female consumers in their 20s and 30s residing in the Seoul and Gyeonggi area. Factor analysis and Cronbach's ${\alpha}$ coefficients, ANOVA, Duncan's Test, and multiple regression analysis were employed for the data analysis. The results revealed that individual self-concepts on health, sports competence, and fitness were influenced by swimming experiences. There was a tendency for those with a longer period of swimming experience to have a higher level of brand consideration as a swimsuit selection criterion; in addition, they showed a higher satisfaction level with swimsuits. Individual physical self-concept influenced the consideration given to each swimsuit selection criterion as well as swimsuit purchase satisfaction level. The findings of the study reflect the possibility of utilizing swimming experiences as a criterion for swimsuit market segmentation. Attention to the quality of swimsuits as well as to the physical self-concept of consumers are required for marketing activities.

Background: Plyometric exercise is an exercise exerting forceful power in a brief period using isotonic activation. It is effective to improve reaction of muscle, agility, endurance and athletics performance. Weight training is an exericse improving muscular strength, endurance and respirating ability applying diversely in frequency and load of exercise Plyometric exercise and Weight training is to facilitate the athletics performance though improving the function of lower limb muscle, there is a difference that Plyometic jump squats is the way to improve agility and Weight training is the way to improve muscular strength. Therefore, it is necessary to know how this difference effects on athletics performance as measuring ankle, ROM, and jumping ability. Design: Randomized controlled trial. Method: This study was conducted with the voluntary participation of 40 university students, who were randomly assigned to jump squat and calf raise groups (n=20 per group). For each subject, we measured the range of motion of the ankle joint before and after exercise, as well as a standing broad jump and vertical jump test performance. We compared the performance indices before and after exercises using paired t-tests, and between groups using independent-samples t-tests. Conclusions: Both jump squat and calf raise exercises improved ankle joint dorsiflexion and plantar flexion, as well as standing broad jump and vertical jump height performance. However, there were no significant differences before versus after exercise, or between exercise types. Although jump squats and calf raises have different purposes, it is thought that, in combination, these exercises improve performance more effectively than either alone, and that such a combined exercise program improves the quality of training in both the general public and athletes in various sports.

Purpose : This study aimed to investigate the effects of 12 weeks of resistance exercise on body composition, physical strength, blood lipids, and insulin. Methods : The study was conducted on 24 elderly women divided into two groups: 12 subjects in an exercise group and 12 subjects in a control group. Resistance exercise was performed for 50 minutes a day, three times a week, for the duration of 12 weeks, and body composition, physical strength, blood lipids, and insulin were measured before and after the subjects completed the program. For the statistical analysis, the mean and standard deviation (M±SD) of each variable were calculated using SPSS version 20, and a paired t-test and two-way repeated ANOVA were conducted to test for the differences before and after the resistance exercise. All significant levels were set to α=.05 as a result of the experiment. Results : Changes in body composition after the 12-week resistance exercise program did not show any significant difference based on the comparison between the groups, but when noting the values for body fat percentage and body in the control group before and after, a significant difference was shown in fat mass (p<.05). As for changes in physical fitness, significant differences appeared in flexibility, muscle strength, and stenotic force (p<.01) when the groups were compared. Regarding pre- and post-values within each group concerning flexibility within the exercise group, significant differences were shown in gender (p<.001), muscle strength (p<.05), (p<.01), muscle earth strength, equilibrium (p<.01), stenosis force, and cardiopulmonary earth force (p<.001). Also, comparisons between populations in changes in blood lipids the values before and after in each group, significant differences in glucose (p<.05) and insulin (p<.05) were shown in the exercise group. When comparing the values before and after in each population, a significant difference was shown in the control group (p<.05). Conclusion : When all the results were integrated, the 12-week resistance exercise program was found to enhance physical strength (flexibility, muscle strength, and coordination) and improve the blood sugar levels of elderly women. In particular, resistance exercise is believed to lower the prevalence of obesity, type 2 diabetes mellitus, and metabolic diseases by having a positive effect on insulin. Further studies are suggested to verify the effect on body composition and blood lipids by setting up a variety of exercise treatment methods (including subjects, exercise periods, exercise plans, and exercise intensity focuses).

Originating in South Korea, Taekwondo has been globally popular among individuals who desire to improve their health in a unique fashion. The Taekwondo uniform, one of the essential factors within the sport, needs to possess both functionality and size suitability to support dynamic movements within Taekwondo. This study investigated the development of patterns in Taekwondo uniforms by suggesting patterns that reflect physical suitability derived from appearance tests and movement functionality tests of the uniforms. More specifically, we selected a sample uniform and conducted a dressing test, which considered both the aesthetics and the functionality of the garment. Then, we considered size suitability, which allowed us to design practical Taekwondo uniform patterns that encompassed more variation in body sizes of both men and women. The result of the dressing test was that women's uniforms typically required more factors compared to men's uniforms due to women's relatively smaller physiques. Based on this result, we revised the pattern to also encompass the minor differences in uniforms between men and women. In the end, the Taekwondo uniforms for women required more modifications than those for men.

The elderly population of Korea has been significantly increasing due to advances in public health, medical care, and quality of life. Social and economic influence of the elderly population has been also increasing. A elderly people become more interested in their appearance and clothing than before, clothing plays an important role in the elderly women's everyday life. The objectives of the research are to explore the life satisfaction, appearance satisfaction, clothing satisfaction, and clothing design preference of 416 women aged 55 years and older were residents of Seoul. Data were gathered through survey using a self-administered questionnaire from November, 1994 to January, 1995 in 8 senior schools and 3 senior centers which were scattered in Seoul. Descriptive statistics, t-test, and factor analysis were used in analysing the data. The results of this study indicated that life satisfaction have a positive relationship with clothing satisfaction. The respondents were divided into tow groups by life satisfaction. The higher life satisfaction group preferred skits and formal wear to the lower. But, two groups did not show any significant differences in terms of the colo preference, motif preference, and fabric preference. The result of factor analysis divided appearance satisfaction into body satisfaction and face satisfaction. Body satisfaction had a positive relationship with clothing satisfaction. And the group of lower physical satisfaction showed lower satisfaction in apparel fitness. Also the face satisfaction had a positive relationship with clothing satisfaction. The group of higher physical satisfaction preferred skirts and foraaml wear compared to that of lower physical satisfaction. The color preference and motif preference between two groups showed no significant difference. And the group of higher physical satisfaction preferred fabric that enhances the clothing style. Also, the group of higher ace satisfaction preferred fabric that enhances the clothing style. However, there was no significant difference in the color preference and motif preference between tow groups. The findings of this study amy contribute to knowledge about clothing satisfaction and preference of elderly women in Seoul since there have been few studies, and be useful to apparel manufacturers as well s clothing researchers. Also, research subjects of this study could be extended to aged men and various regions.

This study investigates the relationship between muscular strengths and gait characteristics of the elderly. Totally, 107 subjects, aged 65 to 85 years, participated in this study. Researchers measured muscle strengths (grip force, toe grip force, gluteus medius, and gluteus maximus forces) and walking characteristics (walking speed, cadence, step length, single leg support, and double legs support). Dynamometers and inertial measurement unit-based shoe systems were used for measuring muscular strength and gait characteristics, respectively. No significant difference was observed in strengths and walking characteristics between the young elders (YE, 65-74 years) and the old elders (OE, 75-85 years). For each age, muscular strength significantly correlated with some gait parameters. Forces of gluteus medius and gluteus maximus muscles showed better significant correlations between some gait parameters for all age groups, as compared to grip force and toe grip force. Regression coefficients between walking speed and grip force did not vary with age. We conclude that muscular strengths in OE better explained the gait characteristics than in YE subjects. Even though grip strength is an easily measured variable for senior fitness test, forces of gluteus medius and gluteus maximus muscles are more meaningful for understanding the walking characteristics of elderly people.

The purpose of this study was to analyze the effects after having the obesity education with obese elementary school children. The subjects were made up of 31 obese children out of U elementary school in B town as experimental group, and also were selected 34 children out of S elementary school under the same circumstance as control group. They ranged from the third to sixth grades with over 30% body fat ratio. The proceeding of obesity education consisted of three stage; stage for preparation, stage for practice, and stage for finish. The stages mentioned above were put into practice in turn for eleven weeks beginning on Oct. 8, 2001 through Dec. 22, 2001, while two stages only, stage for preparation and finish, were put into practice on the control group. The contents of the education for eleven weeks obesity regulation contained counseling and taking regular exercises once a week by professional gym teacher. In order to evaluate the effects of the education, physical characteristics, body composition, physical fitness, knowledge of obesity, dietry habit and attitude were measured. The obtained data were analyzed using SPSS program, the effects of pre and post obesity education in experimintal group were measured by paired-t test. The conclusions of this study were as follows : 1. Body fat ratio was significantly reduced after obesity education in experimintal group(p=.003). 2. The height with experimental group got taller remarkably(p=.000), but weight showed no signeficance after obesity education(p=.258). 3. Triceps and subscapular skinfold thickness showed remarkable decrese after obesity education(p=.000), percentage body fat and body fat amount got down remarkably after obesity education(p=.000). Percentage lean body mass and lean body mass amount got down remarkably after obesity education(p=.000). 4. Body flexibility, agility and muscle endurance graded up remarkably after obesity education(p=.009, p=.000, p=.000). 5. The grade in obesity knowledge got up remarkably after obesity education(p.000), but dietry habits and its life showed no significance in figures after obesity education(p=.335, p=.112). Through the results shown above, the obesity education caused body fat ratio, physique, body composition to grade up and physical fitness elevated, while dietry habits and its life showed no significance.
