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.

The purpose of this study is to investigate and reveal the effects that the complex exercise training consisting of aerobic exercise and strength training(sit up, push up) that everyone can easily practice regardless of a time and a place in order to manage practically the physical strength of the aged affects the difference on their body composition and the change of physical fitness level. Looking into the change of body composition of an experimental group, the weight of 2.5kg was reduced after applying complex training for 12 weeks and the body fat mass of 2.65kg was reduced. Also, the abdominal fat of 0.13% was decreased and the muscle mass of 1.56kg was increased. For the change factors of physical fitness, cardiovascular endurance, muscular strength, muscular endurance, balance and flexibility excluding agility showed significant improvement after applying complex exercise training. The improvement of health fitness of the aged under this study was significantly effective to improve specified body functions which had been lowered by aging and insufficient physical activities. So, it is regarded that their health fitness is the important factor to improve the activity competence required for daily life and to lead healthy living by the improved activity competence. Henceforth, it needs to study more the complex composition of several sports, exercise intensity and the frequency based on the previous researches and studies. In addition, it needs to develop the complex exercise training in accordance with various characteristics such as a sex of the aged, an age, a physical fitness level, environment, a disease and the program in consideration of the efficacy and safety during training.

This article is a socio-cultural research on the fitness members by employing an original synthesis of the work of Elias and Bourdieu. The purpose of this research is to provide a multidimensional and in-depth analysis of fitness members, by researching the relationship between body groups with differing economic and cultural capital (e.g. Gangnam and Gangbuk, private and public center). Through interviews and participant observation, the established and outsider relations of fitness members in both Gangnam and Gangbuk are examined (Gangnam 12: Gangbuk 12). Participants in social space differentiated by fitness capital and socio-economic positions gather in certain spaces that identify them as members of the same class location: the established body in Gangnam (Gangnam E), the outsider body in Gangnam (Gangnam O), the established body in Gangbuk (Gangbuk E), and the outsider body in Gangbuk (Gangbuk O). The E-O figuration of the body in fitness clubs shows differences in their body tastes and habitus (selecting a fitness centre, body ostentation, social assessment, making muscles, participation in other sports) and civilizing process (fitness manners and etiquette). The fitness centers in Gangnam and Gangbuk were not simply spaces for exercise but symbolic spaces that both recreate and perpetuate socio-cultural hierarchies between members.

The objective of this study is to investigate the market of fitness compression wear as well as to design an optimal fitness compression wear by analyzing the muscle and movement characteristics of the elderly women in Korea. In this regard, research for functional garments is needed to increase muscle activity of elderly people during physical exercise. Firstly, we investigated the brand, design, size, material, and pattern of fitness wear based on the market survey. Secondly, we identified preference, evaluation items, evaluation method, and pattern design method based on the literature review. Finally, in addition, the motion type, range, angle to improve the muscle strength of the elderly were investigated and the maximum muscle strengths of each motion were analyzed by using 2007 Size Korea data (n = 386). It is also designed for muscle fatigue through exercise and rapid fatigue recovery after exercise. The evaluation methods for fitness compression wear were classified as motor functionality, physiological comfort, pattern and material suitability evaluations. The muscle strength at leg (pushing force) and waist (lifting force) of the ages of 60 to 69 years old showed 239.3 N and 274.5 N, respectively, which were the lowest forces compared to younger age groups. By applying these results to the design process of fitness wear, it is anticipated that the fitness wear will have a proper fit to the body shape of elderly people in South Korea as well as it can increase muscle efficiency to promote physical capability and healthy life for senior people.

This study was aimed to verify a comparison by dental alloys upon the marginal fitness of dental prosthesis. Firstly, we waxed up on 45 epoxy resin dies, pressed the margin with hands, and identified the marginal fitness with microscope. And we made a single direct spruing system type of sprue by 3 dental alloys - metal crown alloys, PFM crown alloys, and gold crown alloys - each 15, total 45 waxing up, adjusting W/P ratio and invested the cast ring. Then, we made the dental prosthesis using the electric casting machine. In these processes we followed the manufacturer's instructions, in order to maintain the other conditions from the inner and outer, which included investment and burning out. After we tried on the dental prosthesis on epoxy resin dies, we have got the means of marginal gap at 9 points with same distances, around the cervical line which was checked already, using microscope($\times$300). The results of this study were as follows : 1. Metal crown alloys showed 2.9% better in marginal fitness than PFM crown alloys, and the difference was not statistically significant(P=0.497). 2. Gold crown alloys showed 31.3% better in marginal fitness than Metal crown alloys, and the difference was statistically significant(P=0.004). 3. Gold crown alloys showed 32.4% better in marginal fitness than PFM crown alloys, and the difference was statistically significant(P=0.002). 4. We saw that Gold crown alloys was the best dental alloys in the marginal fitness among the three.(P=0.049).

PURPOSE: This study examined the effectiveness of an active lifestyle on the HRV and fitness of the older female adults. METHODS: Eighty female older adults (72.68±3.78 years) were sampled from a senior wellness institute. Accelerometers were distributed to each participant to have the device attached to them for one week, and the physical activity data (Energy expenditure in Kcal) of each participant were analyzed. Participants were divided into 3 groups (<1,000 Kcal vs 1,000 to 1,500 Kcal vs ≥1,500 Kcal) based on the amount of weekly physical activity. Before and after data analysis, the HRV was measured at resting state and the Senior Fitness Test was performed. RESULTS: One way ANOVA showed a significant difference in the HRV between the three groups. Group A (≥ 1,500 Kcal) was superior in HF and HF/HF + LF whereas Group C (<1,000 Kcal) showed high level of LF, LF/HF, and LF/HF+LF. The same statistics revealed significant differences in fitness. Most of the fitness variables were superior in Group A and B compared to Group C. Significant correlations were observed between physical activity and both HRV and in fitness. CONCLUSION: Theses results suggest that an active lifestyle may be an effective intervention for the prevention of both cardiometabolic disorder and improvement of the fitness level in older female adults.
