The purpose of this study was to investigate the characteristics and the current condition of musculoskeletal pain sufferers among fitness center users. The investigation used self-reporting questionnaire with the 797 subjects. On average, the subjects were 30.6 years old, 168.8 cm in height and 65.2 kg in weight. Among them, 423 were male (53.1%) and 374 were female (46.9%). Out of them, 276 suffered from pain, (35.2%). More men felt muscle aches than women (p<.05). In terms of pain, lower back area topped the list with 44.9%, followed by the lower extremities (30.1%), the neck (17.8%) and the upper part of the body (17.8%). Dieters suffered the most from pain (86.2%) while those exercising to build strength suffered the least with 26.8%. There was a significant relationship between the purpose for exercising and the amount of pain suffered (p<.05). By kind of exercise, pain stroke aerobic exercisers disproportionately with 42.4% while it almost steered clear of exercisers for strengthening with 26.9%. There was significant relationship between the kind of exercise and pain suffered (p<.05). The type of suffering differed by body shape. A significantly higher number of overweight people experienced pain than underweight people (p<.05). 32.8% of pain sufferers commented that the pain affects their workout, and on this issue there was no gender difference (p>.05). The pain caused more difficulties in doing activities of daily living for overweight or obese peoples than underweight peoples (p<.05). More than a third of health club and fitness center users are experiencing musculoskeletal pains. Measures such as professional training or information provision is required to prevent injury or disorder caused by improper exercise.

The purpose of this study is to offer basic data for the fall prevention by analyzing the kinematic difference between the lower limb joints and the lower extremities in elderly people's walking given the lower-limb resistance exercises. For this, three-dimensional image analysis was carried out by selecting 7 elderly women from over 70s to under 80 years old. To obtain the three-dimensional location coordinates in the lower limb joints and the lower extremities, it shot with 100Hz/s by using MCU(Qualisys, Sweden) camera. The shot image gained raw data on the location coordinates by using QTM(Qualisys, Sweden). As a result of calculating three-dimensional angle by using program of Matlab 6.5, the following conclusions were obtained. Flexion and extension in the thigh and the lower-leg extremities were indicated to be big in motion of flexion after exercising at E5. Foot segment indicated statistical difference while showing eversion at E4. Knee joints showed flexion at E4 after exercising. Ankle joints showed statistical difference while indicating motion in inversion at E3 and in eversion at E4(p<.05).

BACKGROUND/OBJECTIVES: Energy production and the rebuilding and repair of muscle tissue by physical activity require folate and vitamin $B_{12}$ as a cofactor. Thus, this study investigated the effects of regular moderate exercise training and durations of acute aerobic exercise on plasma folate and vitamin $B_{12}$ concentrations in moderate exercise trained rats. MATERIALS/METHODS: Fifty rats underwent non-exercise training (NT, n = 25) and regular exercise training (ET, n = 25) for 5 weeks. The ET group performed moderate exercise on a treadmill for 30 min/day, 5 days/week. At the end of week 5, each group was subdivided into 4 groups: non-exercise and 3 exercise groups. The non-exercise group (E0) was sacrificed without exercising and the 3 exercise groups were sacrificed immediately after exercising on a treadmill for 0.5 h (E0.5), 1 h (E1), and 2 h (E2). Blood samples were collected and plasma folate and vitamin $B_{12}$ were analyzed. RESULTS: After exercise training, plasma folate level was significantly lower and vitamin $B_{12}$ concentration was significantly higher in the ET group compared with the NT group (P < 0.05). No significant associations were observed between plasma folate and vitamin $B_{12}$ concentrations. In both the NT and ET groups, plasma folate and vitamin $B_{12}$ were not significantly changed by increasing duration of aerobic exercise. Plasma folate concentration of E0.5 was significantly lower in the ET group compared with that in the NT group. Significantly higher vitamin $B_{12}$ concentrations were observed in the E0 and E0.5 groups of the ET group compared to those of the NT group. CONCLUSION: Regular moderate exercise training decreased plasma folate and increased plasma vitamin $B_{12}$ levels. However, no significant changes in plasma folate and vitamin $B_{12}$ concentrations were observed by increasing duration of acute aerobic exercise.

The purpose of this study was to investigate the effect of vitamin B2 deficiency on the utilization and recuperation of fuel in exercising rats. Thirthy six rats were fed either a vitamin B2 deficient diet (-B2) or a control diet (+B2) for 3 weeks and then subdivided into 3 groups : non-exercise group(NE), exercise group (ES), exercise and recuperation group (ER). ES group were exercised on treadmill (10$^{\circ}$, 0.5-0.8km/h) for 2 hours and ER group were recuperated three days with the respective diet after exercise. Glucose (GLU), glycogen(GLY), protein(PRO), triglyceride(TG) and free fatty acid(FFA) were compared in plasma(P), liver(L) and skeletal muscle(M) of rats. Compared to + B2 rats, in NE group, the level of P-GLU and L-GLU of -B2 rats was lower, L-PRO and M-GLY was higher and there were no differences in P-PRO, P-FFA, L-TG and M-TG. In ES group, the level of P-GLU was lower, P-FFA was higher and there were no differences in P-PRO, P-TG, L-GLU, L-TG, M-GLY, M-TG and M-PRO. In ER groups, the level of P-GLU and L-TG was lower, P-FFA was higher and there were no differences in P-PRO, P-TG, L-GLY, L-PRO, M-GLY, M-TG and M-PRO. These results suggest that a vitamin B2 deficiency may impair the utilization of stored fuel during exercise suggest that a vitamin B2 deficiency may impair the utilization of stored fuel during exercise and may lead a sluggish recuperation related to fuel stores after exercise.

Recently, because the market for compression wear now includes all consumers, not just professionals, various items for recovery after exercising or for enhanced effects from exercise have been introduced. In this research, a systematic and stepwise design process was proposed to develop compression garment that has both functional area and appropriate pressure to protect the knee when exercising. The U-V format functional area that wraps underneath the knee was selected by considering the shape and change in the skin length when bending the knee. After the selection of the functional area, a total of seven knee design areas, including the existing product, were designed to determine the appropriate pressure. After various movements, the compression garment was ranked in terms of support of the knee, level of pressure, discomfort of seam line, and comfort of popliteal; the preferred design was selected using the quad method. Four compression wear garments were produced using two selected preferred designs; the wear evaluation was performed using a seven-point Likert scale. As a result, the optimal reduction rate of the pattern was calculated based on Ziegert and Keil's method. The applied percentage of the fabric stretch at the upper part of the crotch was 66% for the width and 50% for the length; for the lower part of the crotch, only 66% for the width was applied. Moreover, it was determined that the design of the U-V knee protection part was preferred when a 7 mm square was placed at a 1 mm distance because this not only supports the knee but also allows the fabric to accommodate various skin deformations.

Vitamin E in the body system plays an important role in preventing chronic diseases by decreasing the oxidative stress by free-radicals. However, there are not enough researches on analyzing the primary factors affecting vitamin E levels in the blood in Korean adults. Therefore, the purpose of this research was to examine blood tocopherol levels and the primary factors affecting the status. A complete lifestyle survey was performed on 314 Korean adult men and surveyed their smoking, drinking and exercising habits. The average plasma level of ${\alpha}-\;and\;{\gamma}-tocopherol$ showed similar mutual relations with plasma total cholesterol (TC), triglyceride (TG), or low density lipoprotein cholesterol (LDL-C) levels (p<0.001). Plasma ${\alpha}-tocopherol$ level of the subjects did not show any difference as smoking, drinking and exercising habits changed. However, ${\gamma}-tocopherol$ per TG showed much lower figure in smokers than non smokers (p < 0.05). Amongst diet factors, plasma ${\alpha}-tocopherol$ level showed negative correlations with Vitamin E intake, while ${\gamma}-tocopherol$ level showed positive correlations with Vitamin E intake. Erythrocyte superoxide dismutase (SOD) activity and plasma tocopherol showed negative correlations, and catalase activity and plasma ${\alpha}-tocopherol$ showed positive correlationship. The level of cell DNA damage of Iymphocyte and plasma ${\alpha}-\;or\;{\gamma}-tocopherol$ showed negative correlations. As a result of this research, the factors that affect Korean adult men's plasma ${\alpha}-tocopherol$ level are plasma TG, LDL-C and cell DNA damage in Iymphocyte, while the factors that affect ${\gamma}-tocopherol$ level are plasma TG, LDL-C and vitamin E intake based on multiple regression analysis. These findings implies that the level of different types of tocopherol depends on slightly different factors. A further research is needed on the factors involved in the differentiation of the types of tocopherol.

The purpose of this study is to examine the effect of stabilization, resistance exercise, and combined exercise for lumbar on balance and walking ability of elderly. This study selected 22 subjects of over 65 years old elderly women who satisfy the study condition from A, B and C Senior Citizen's Center, in Daegu. The subjects were divided into groups; 7 for resistance exercise group, 8 for stabilization exercise group, and 7 for combined exercise group(resistance and stabilization exercise). The exercises were conducted for 60min a day, three times a week for 12 weeks. Balance and walking ability were checked before the exercise, 6 weeks later, and 12 weeks later. First, all lumbar muscle strengthening exercises were effective for static balance which changed according to exercising period. In dynamic balance, the resistance exercise group showed significant improvement in sit to stand. Stabilization exercise group showed significant improvement in all factors. The combined exercise group showed significant improvement in sit to stand and timed up and go. There was no difference between the exercise types. Second, the resistance exercise group showed significant change in Cadence which changed according to exercising period. The combined exercise group showed significant improvement in all factors. Between the exercise types, combined exercise was a bit more effective than resistance exercise. According to the result of 12 weeks of lumbar muscle exercise, combined exercise is considered to be the most effective exercise to prevent fall as it helps balance and walking ability slightly more than other exercises. Therefore, this study can understand the risk factors for fall accidents that frequently occur among elderly and adopt the combined exercise to prevent fall which in turn will prevent secondary problems occur from fall accidents and improve quality of life of elderly.

This study was designed to analyze the results of Vaso-Aging Degree in Oriental medical examination. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 24,077 industrial workers who had received Oriental medical examination by Oriental medicine and they submitted questionnaires about drinking history and smoking history, during 9 months from March to November. They were categorized by job class, drinking history and smoking history, exercising history. The percentage of Vaso-Aging Degree were measured by using SA3000P(Medicore, Seoul, Korea). We analyzed the relationship between job class, drinking history, smoking history, exercising history and Vaso-Aging Degree using ${\chi}2$-test of the SPSS Ver. 14.0. In job class, Sales personnel were apt to have a higher level of Vaso-Aging Degree than Office workers. And getting older workers are, the higher Vaso-Aging Degree becomes. Vaso-Aging Degree of the Drinker group showed a higher level than the Non-Drinker group. Vaso-Aging Degree of Smoker group were higher than the Non-smoker group. On the other hand, Vafo-Aging Degree of Non-Exerciser group were higher than the Exerciser group. They have to manage Vaso-Aging Degree closely and educate the workers to quit smoking and drinking for their health promotion. Furthermore, continuous health check up needs to be done connectedly.
