Objective: This study is to investigate the effect of real-time feedback from the therapist on posture, muscle strength, pain of subjects with forward head posture based on a non-face-to-face complex exercise program. Design: Two-group pretest-posttest design. Methods: Thirty healthy men and women in their twenties with forward head posture with a Craniovertebral angle of 52° or less were targeted, the final selection was made as 15 experimental groups who performed the non-face-to-face intervention program while receiving real-time feedback and 15 control subjects who performed the non-face-to-face intervention program without providing feedback. Six of them were eliminated, and a total of 24 were conducted as subjects. All exercise groups performed an exercise program three times a week, 30 minutes each, for a total of two weeks. Before and after exercise, Craniovertebral angle (CVA), CranioRotation angle (CRA), muscle strength, and tenderness threshold were evaluated. Results: Significant differences were shown in both groups in CVA, and tenderness threshold before and after exercise (p<0.05), and CRA, the left middle trapezius muscle strength, only in the experimental group (p<0.05). In the comparison of theamount of change between exercise groups, the group that received feedback on CVA, CRA and tenderness threshold showed a significant change than the group without feedback (p<0.05). Conclusions: As a result of this study, it can be seen that the therapist's real-time feedback is more effective in improving the forward head posture. This requires feedback from the therapist on posture correction during non-face-to-face exercise intervention.

Objectives : The effects of exercise on bone density have been found to be inconsistent in previous studies. We conducted a cross-sectional study in premenarcheal girls to test two hypotheses to explain these inconsistencies. Firstly,'the intensity of mechanical strain, in terms of the ground reaction force(GRF), has more important effects on the bone mass at a weight-bearing site', and secondly, 'calcium intake modifies the bone response to exercise'. Methods : The areal bone mineral density was measured at the Os calcis, using peripheral dual energy X-ray absorptiometry, in 91 premenarcheal girls aged between 9 and 12 years. The intensity of mechanical strain of exercise was assessed by a self-report questionnaire and scored by the GRF as multiples of body weight, irrespective of the frequency and duration of exercise. The energy and calcium intake were calculated from the 24-hour dietary recall. An analysis of covariance(ANCOVA) was used to determine the interaction and main effects of exercise and calcium on the bone density, after adjusting for age, weight, height and energy intake. Results : The difference in the bone density between moderate and low impact exercise was more pronounced in the high than low calcium intake group. The bone density for moderate impact exercise and high calcium intake was significantly higher than that for low impact exercise (p=0.046) and low calcium intake, after adjusting for age, weight, height and energy intake. Conclusions : Our study suggests that the bone density at a weight-bearing site is positively related to the intensity of mechanical loading exercise, and the calcium intake may modify the bone response to exercise at the loaded site in premenarcheal girls.

Purpose: The purpose of this study was to investigate the effect of stretching, muscle strengthening, and walking exercise on the cardiopulmonary function and health-related quality of life in hemodialysis patients. Methods: Twenty-one patients in the intervention and the control group participated in the exercise respectively on maintenance hemodialysis at four university hospitals. The exercise was composed of 20 to 60 min per session, 3 sessions a week for 12 weeks. The effect of exercise was assessed by cardiopulmonary function (peak oxygen uptake, peak ventilation, peak respiration rate, maximal heart rate, and exercise duration) using a cycle ergometer. Grip strength was measured by dynamometer, and flexibility was measured by sit and reach measuring instrument. Health-related quality of life was measured using Medical Outcomes Study Short Form-36. Results: Peak oxygen uptake, peak ventilation, peak respiration rate, exercise duration, grip strength, flexibility, and physical component scale were significantly improved in the intervention group after 12 week's exercise compared to the control group. Conclusion: These findings indicate the exercise can improve cardiopulmonary function, grip strength, flexibility, and physical component scale of health-related quality of life in hemodialysis patients.

Purpose: The Purpose of this research was to develop the integrative exercise program for the elderly. Method: The first step was to survey the elder's health status and general health problems. The second step was to design the exercise type, intensity, time and frequency. Result: 1. Elders who implement the integrative exercise program had weaker health status, lower physical performance and more depression than any other places. 2. The integrative exercise program developed the preparation stage composed of stretching and Yudongkong-Ki exercise, the central stage was composed of range of motion exercise, muscle strength exercise and aerobic exercise with favorite and popular Korean music. The finishing stage was composed of joint rounding and Yudongkong-Ki exercise. The exercise intensity was RPE(rating perceived exertion) 10-11, maximal pulse rate 40-60%, duration started from 20min to 50min and frequency is 2-3times/wk. Conclusion: The integrative exercise program developed by the researcher is tailored exercise that is more applicable to individual cases in community settings. Eventually, the program is safely applicable to the elders, and is expected to improve the elders' physical function and quality of life.

[Purpose] The combined effect of different types of post-exercise treatment has not been fully explored. We investigated the effect of combined cold water immersion (CWI) and compression garment (CG) use after maximal eccentric exercise on maximal muscle strength, indirect muscle damage markers in the blood, muscle thickness, and muscle soreness score 24 h after exercise. [Methods] Ten men performed two trials (CWI + CG and CON) in random order. In the CWI + CG trial, the subjects performed 15 min of CWI (15℃), followed by wearing of a lower-body CG for 24 h after exercise. In the CON trial, there was no post-exercise treatment. The exercise consisted of 6 × 10 maximal isokinetic (60°·s^-1) eccentric knee extensions using one lower limb. The maximal voluntary contraction (MVC) and maximal isokinetic (60°·s^-1) strength during knee extension, as well as the indirect muscle damage markers, were evaluated before exercise and 24 h after exercise. [Results] The maximal muscle strength decreased in both trials (p < 0.001), with no difference between them. The exercise-induced elevation in the myoglobin concentration tended to be lower in the CWI + CG trial than in the CON trial (p = 0.060). The difference in the MVC, maximal isokinetic strength, muscle thickness, and muscle soreness score between the trials was not significant. [Conclusion] CWI followed by wearing of a CG after maximal eccentric exercise tended to attenuate the exercise-induced elevation of indirect muscle damage markers in the blood.

Purpose: The purpose of this study is to examine the effect of stretching exercise education on female workers' behavior for preventing musculoskeletal diseases. Method: This study educated occupational health nurses working in Seoul and Kyunggi area for stretching exercise methods and then had them educate female workers in each workplace for the stretching exercise methods. The subjects of this study were 205 female workers and the research period was from June to October 2003. Results: The female workers' self-efficacy on stretching exercise increased significantly. The female workers' perceived susceptibility on stretching exercise increased significantly. As for change in practical intention on preventive behavior for musculoskeletal diseases, those who replied to have a plan to exercise regularly and to want to participate in stretching exercise class increased significantly. According to whether to have subjective musculoskeletal symptoms or not, self-efficacy increased significantly after education in both workers with such symptoms and those without, and perceived susceptibility and cue to action increased significantly after education in workers without such symptoms. Conclusion: It is necessary to develop programs to increase self-efficacy and health belief and to apply them to female workers to prevent musculoskeletal diseases. In addition, it is necessary to provide repeated education for female workers' steady practice of preventive behavior.

Purpose: This study was designed to explore the stage distribution of subjects according to stages of change for exercise and to identify factors that could discriminate subjects in various stages. Methods: The sample consisted of 182 subjects who had metabolic syndrome. The instruments used in this study were the stage placement instrument for exercise, the metabolic syndrome knowledge and metabolic syndrome health belief scale, and the metabolic syndrome exercise self efficacy scale. Data were analyzed using chi-square, ANOVA, and discriminant analysis by using the SPSS 19.0 program. Results: For exercise stages, exercise efficacy, occupation, and exercise benefit showed high standardized canonical discriminant function coefficients. Subjects in precontemplation/contemplation stage for exercise were more likely to have occupations, had less exercise efficacy and exercise benefit than those in other stage. Conclusion: This study implies that the level of exercise efficacy and exercise benefit of subjects in precontemplation/contemplation stage need to be enhanced in developing exercise program incorporating the stage of change for metabolic syndrome patients.

Purpose: This study attempts to determine the effects of water-based exercise performed on stroke patients in their muscle activity of lower extremity and gait ability tests. Methods: The subjects were 20 stroke patients, who were randomly divided into a water-based exercise group and a land-based exercise group, each including 10 patients. Both exercises were performed 3 days per week, for 40 minutes a day, for a period of eight weeks. Results: The water-based exercise group showed a greater increase in muscle activity of lower extremity compared to the land-based exercise group. The water-based exercise group showed a greater increase in gait ability than the land-based group, showing a significant difference and better efficiency of water-based exercise when compared to land-based exercise. Conclusion: From the result of this study, we found that water-based exercises are more effective in improving muscle activity of lower extremity and gait ability. The patient is considered to be used by itself to involve the treatment and the risk of falling from the lowered state into the treatment method for the intensive treatment of stroke patients to be useful in improving the strength and ability to walk.

Stress at work as well as at home is one of the most important issues in the health sector. However, very little research has been to find the relationship between the levels of stress and exercise. In this study, we used a structured questionaires received from 15th June to 29th October 2002 in order to prove the relation between the degree of exercise and stress. A total number of 1,092( 569 male, 523 female) who have worked more than one year were investigated. The results of the study were as follows： (1) The mean levels of stress were lower in the regualr exercise group than in the non-exercise group； (2) The more time spent in exercise, the lower level of stress was shown； (3) It was shown that the association between the frequency of stress was inversely realted to the frequency of exercise in males whereas the levels of stress was lowest in those who exercised less than 2 times per week in females； (4) The levels of stress was lowest in those who exercised more than 1 hour at a time. In summarizing the result of this study, the degree of exercise is realted with stress regardless of gender. Consequently, it is expected that regular and consistent exercise would be an important tools in lowering and protecting the worker's stress.

Purpose: The purpose of this study was to examine relationships between perceived exercise benefits/barriers, competence, depression, and wellness, and then to identify influencing factors on the wellness of traditional market traders. Methods: One hundred eight persons working in a traditional market participated in the study of questionnaire. Data were analyzed using t-test, ANOVA, and multiple regression. Results: The scores were 2.82±0.66 for "perceived exercise benefits", 1.84±0.42 for "perceived exercise barriers", 4.68±1.56 for "competence", 9.60±7.56 for "depression", and 3.64±0.64 for "wellness". Regression analysis to identify factors affecting the wellness of traditional market traders showed that "perceived exercise benefits" was the most significant factor (β=.32, p<.001), followed by "competence" (β=.04, p=.009) and "depression" (β=.17, p=.039). The explanatory power of these variables for wellness of traditional market traders was 53%. Conclusion: Our findings suggest that perceived exercise benefits, competence and depression are significantly related to traditional market trader's wellness. Therefore, wellness programs should be developed to reduce depression and improve perceived exercise benefits and competence.
