Purpose: The purpose of this study was to confirm the effects of a moderate and fast walking exercise program on middle-aged women's fatigue, serum lipids and immunoglobulins. Method: A non-equivalent control group pretest-posttest design was used for this study. The experiment was conducted for 10 weeks from May 17th to July 25th, 2004 with 44 middle-aged women, consisting of 16 for the moderate walking group, 15 for the fast walking group and 13 for the control group. Result: Walking exercise at both a moderate and fast speed was effective in middle-aged women in reducing fatigue and serum lipids. It was also revealed that extended periods of exercise was more effective in decreasing fatigue while for reducing serum lipid, high intensity exercise was more effective. In this study, serum immunoglobulins were reduced after moderate and fast walking exercise but its cause was not fully understood so further research is needed. Conclusion: This study helps us recognize the importance of regular exercise and promotes motivation to exercise for a healthy life among middle-aged women.

The immune response to any stimulus is complex, requiring coordinated action by several types of cells in a tightly regulated sequence. Thus, a physical stress such as exercise may act at any number of points in the complex sequence of events collectively termed the immune response. Although exercise causes many propound changes in parameters of immune function, the nature and magnitude of such changes rely on several factors including the immune parameters of interest; type, intensity, and duration of exercise; fitness level or exercise history of the subject; environmental factors such as ambient temperature and humidity. Although regular moderate exercise appears to be important factor for increasing immunity, Athletes are susceptible to illness, in particular upper respiratory track infection, during periods of intense training and after competition. In addition, in elite athletes, frequent illness is associated with overtraining syndrome, a neuroendocrine disorder resulting from excessive training. Through this paper, we want to investigate the effects of exercise on the immunosuppression such as exercise induced lymphopenia, asthma, anaphylaxis, URT (upper respiratory track), and TB (tuberculosis) infection. and also, we want to suggest a direct mechanism, protection and therapy of exercise induced immunosuppression.

The purpose of this study is to determine the effects of exercise programs on the treatment of chronic diseases. For this purpose, nine middle-aged women suffering from such chronic diseases as obesity, hypertension and coronary heart disease(CHD) were sampled to perform a 4-month-long exercise program which required the lactate threshold(LT) level corresponding to 70% of maximal oxygen uptake(VO2max). Thereupon, their physiques, physical fitness, blood components and physiological varibles were compared pre and post of exercise program. The results were summarized as follows ; 1) After the 4-month-long exercise program, %fat was significantly decreased, while such variables as grip strength, side step, trunk flexion and leg balance were significantly increased. 2) Blood components such as TG, TC, HDL-C, LDL-C, hemoglobin and hematocrit did not show and change in after exercise program. 3) Physiological varables such as HR, SBP, DBP, HR/LT, SBP/LT, DBP/LT, RPE/LT, VE/LT, VO2/LT and VO2 max showed significant increase after 4-month exercise program. These results suggest that regular aerobic exercise in a long period might help to decrease % fat and to increase aerobic capacity in middle-aged women suffering from chronic diseases.

We studied the effects of soy isoflavones supplementation with exercise on bone mineral density and the urinary excretion of deoxypyridinoline as an index of bone resorption rates in postmenopausal women. A total of 67 postmen-opausal women were assigned to Isoflavone (90 mg/day) or placebo groups. These group were further divided into groups that undergone a regular exercise or a rather sedentary state performing daily activity only. Four groups were Placebo-control group (n = 16), Placebo-exercise group (n = 16), Isoflavone-sedentary group (n = 19) and Isofla-vone-exercise group (n = 16). After the intervention, we compared anthropometric mesurement, dietary recall, bone mineral density (femoral neck, lumbar spine), urinary deoxypyridinoline between the groups and between the pre and post studies. There were no significant differences between the four groups in terms of average age, height, weight, period after menopause at the baseline. The average age of the subjects were 55.2 yrs, average height, weight, period after menopause were 154.7 cm, 59.3 kg, 5.58 yrs, respectively. After eight week intervention period, there were no significant differences between the four groups in bone mineral density, but urinary deoxypyridinoline excretion was significantly decreased both in Isoflavone-sedentary and Isoflavone-Exercise groups. These results suggest that Isofla-vone supplementation alone or with exercise may be preventive measures through the decrease of bone reabsorption rate in post-menopausal subjects. Whereas exercise alone did not appear to be an effective measure in bone loss with these subjects.

Purpose: The purpose of this study is to find the effects of an exercise program on body composition, serum lipids, and menopausal symptoms in Korean menopausal women. Methods: This research used none qui valent control group pretest-posttest design. The participants were 30 middle-aged women who were divided into two groups, an experimental group (n = 16) who participated in the exercise program and a control group (n = 14). The exercise program was composed of gymnastic-ball exercises with RPE $12{\sim}13$ intensity, 50 minutes' duration and three times a week for 12 weeks from April 1 to June 30, 2008. The dependent variables (body composition, serum lipids, menopause symptoms, self-efficacy, and life satisfaction) were measured before and after exercise program. Results: There were statistically significant difference in weight (F=2.92, p=.049), percent body fat (F=4.22, p=.040), total cholesterol (F=2.63, p= .017) and high density lipoprotein (F=6.74, p= .015) between the two groups. Psychological menopausal symptoms also decreased significantly (F=7.01. p=.014) after the exercise in the experimental group. Conclusions: Regular gymnastic-ball exercises are helpful for menopausal women. They have positive effects not only on body composition and serum lipids but also on the decrease of menopausal symptoms. The results of this study suggest that gymnastic-ball exercise programs are effective in health promotion of Korean middle-aged women, and thus it is necessary to develop exercise programs for women.

Purpose: The purpose of this study was to assess social support, mood, and commitment to a plan for exercise of Korean adults with chronic diseases. Further, the relationships between social support, mood, and commitment to a plan for exercise were assessed. Method: The participants in this study were 230 Korean adults over 18 years of age with chronic diseases who were recruited in hospitals or health centers. The instruments used in this study were Exercise Social Support Scale, POMS (Profile of Mood States), and Commitment to a Plan for Exercise Scale. Result: The results of descriptive analysis showed that Korean adults with chronic diseases were perceived with relatively low commitment to a plan for exercise while they were perceived with moderate social support and mood states. Pearson's correlation coefficient showed significant relationship between these three variables. Stepwise regression indicated that 37% of the variance in commitment to a plan for exercise was explained by social support and vigor factor of the POMS. Conclusion: Health professionals can use this information for planning a targeted strategy to increase regular exercise among Korean adults with chronic diseases in order to improve their quality of life and control disease-related symptoms.

[Purpose] We determined the effect of partial sleep deprivation (PSD) after an exercise session on exercise performance on the following morning. [Methods] Eleven male athletes performed either a normal sleep trial (CON) or a PSD trial. On the first day (day 1), all subjects performed an exercise session consisting of 90 min of running (at 75% ${\dot{V}}O_{2max}$) followed by 100 drop jumps. Maximal strength (MVC) was evaluated before and after exercise. In the CON trial, the sleep duration was 23:00-7:00, while in the PSD trial, the sleep duration was shortened to 40% of the regular sleep duration. On the following morning (day 2), MVC, the metabolic responses during 20 min of running (at 75% ${\dot{V}}O_{2max}$), and time to exhaustion (TTE) at 85% ${\dot{V}}O_{2max}$ were evaluated. [Results] On day 2, neither the MVC nor ${\dot{V}}O_2$ during 20 min of running differed significantly between the two trials. However, the respiratory exchange ratio was significantly lower in the PSD trial than in the CON trial (p = 0.01). Moreover, the TTE was significantly shorter in the PSD trial than in the CON trial (p = 0.01). [Conclusion] A single night of PSD after an exercise session significantly decreased endurance performance without significantly changing muscle strength or cardiopulmonary response.
