Falls are a major sources of death and injury in elderly people. Aged-related changes in the physiological systems which contribute to the maintenance of balance are well documented in older adults. These changes coupled with age-related changes in muscle and bone are likely to contribute to an increased risk of falls in this population. Regular exercise may be one way of preventing falls and fall-related fractures. However, the optimal exercise prescription to prevent falls has not yet been defined. On the literature review of exercise intervention for fall prevention in the elderly, exercise appeared to be a useful tool in fall prevention by improving fall risk factors. The optimum exercise prescription; moderate intensity frequency of 3-4 times per week, duration of 30-60minutes can contribute to decreased hazards and number of fall. Fall prevention protocol should include safety, falling effect, enjoyment, and easiness to follow for older people. Effective exercise programs suggested for fall prevention were such as weight-bearing exercise, resistance exercise, lower muscle strength with elastic band, swiss ball exercise walking, tai chi, and yoga.

Purpose: Women have been often underdiagnosed and undertreated when they have as high mortality as men of ischemic heart disease, such as angina. One of the reasons of women's under treatment is associated with either vague, non-traditional symptoms or longer delay in seeking professional help when they experience ischemic heart disease. This study was conducted to investigate the characteristics of women's anginal pain induced by the treadmill test and to explore the potential relationship(s) between anginal pain and other psycho-physiologic factors. Methods: Of 22 female patients referred to treadmill test, 7 with positive finding participated in this study. Anginal pain in the past was analyzed by Rose questionnaire, whereas anginal pain induced by the treadmill test was identified by McGill pain scale, visual analogue scale and present pain index. Results: Women expressed more heaviness than sharp pain, and complained splitting more often than subjects in previous study that included both men and women. Pain intensity by VAS $3.64{\pm}3.94$, Pain rating index was $5.14{\pm}7.29$, present pain index was $1.57{\pm}1.81$, duration of pain was $5.14{\pm}4.8$ min. Exercise intensity was $6.0{\pm}4.63$ METs, exercise duration was $364.29{\pm}141.39$ sec, ST change was -2.0mm and rate of perceived exertion was $16.29{\pm}2.06$. The relationships between pain intensity and pain duration, ST segment changes were significant. Correlation among pain measures was significant. Conclusion: Generalization of these pilot findings may be inappropriate, and therefore, further larger study is needed.

Acute or repeated physical exercise affects a large number of physiological parameters including hemodynamics, respiration, pH, temperature, gastrointestinal function and biotransformation, which determine the pharmacokinetics of drugs and chemicals. The rate and the amount of a chemical reaching the active site are altered by physical exercise, which results in significant changes in pharmacolosical/toxicological activity of the chemical. This aspect of physical exercise has vast implication in therapeutics and in safety evaluation, particularly for chemicals that have a low margin of safety. However there appears to be a wide inter- and intraindividual variation in the effects of physical exercise depend-ing on the duration, intensity and type of exercise, and also on the properties of each chemical. It is suggested that more studies need to be done to determine which factor(s) plays a major role in the disposition of chemicals in human/animals performing physical exercise. Certain chemicals induce severe toxicity due to metabolic conversion to reactive intermediate metabolites. it is suggested that repeated exercise may enhance the free radical scavenging system by increasing the activity of antioxidant enzymes. This area of research remain to be explored to elucidate the interaction of exercise and chemical on the antioxidant system.

고강도운동의 지속시간이 백혈구 조성과 T-림프구 활성 보조인자로서의 $CD4^+$와 $CD8^+$수준의 변화 그리고 림프수의 세포사에 미치는 영향을 조사하기 위해 쥐실험을 하였다. 고강도 운동을 매일 20, 60, 그리고 120분 동안 8주간 실시하였다. 혈액내의 총 백혈구 수는 20분간 운동을 했을 때 상승하였고 이것은 다시 120분 까지 대조군의 수준 이하로 감소하였다. 림프구의 수준변화 패턴 역시 운동시간의 영향을 받았으며 그 변화 정도는 총 백혈구의 그것과 유사하였다. 고강도운동을 실시한 쥐의 혈액 내 $CD4^+$와 $CD8^+$의 수준은 운동시간이 120분간 지속될 때까지 변화가 없었기 때문에 T-림프구의 활성에는 영향을 주지 않는 것으로 보인다. 거의 모든 초기단계 및 후기 단계의 림프구의 세포자멸사는 운동시간에 영향을 받지 않았으나 120분간 운동한 그룹에서 후기단계의 림프구 자멸사 수준이 증가되는 것으로 보아 이때 세포노화의 촉진이 일어났으리라 사료된다. 운동시간이 길어질수록 림프구의 괴사 수준이 증가되는 것을 확인 하였고 이에 따라 고강도운동에 의한 림프구 손상과 면역력 저하의 가능성이 예상된다. 본 연구에서 장시간 동안의 고강도 운동은 림프구의 염증관련 기능과 세포 수에 있어서의 손상 등을 일으켜 면역력의 저하를 초래할 수 있다고 보며 따라서 적어도 본 연구조건에 한해서 20분 이상의 고강도운동은 건강유지 차원에서 바람직하지 않다고 판단된다.

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.

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: This study examined the immediate effect of Kegel exercise on the vital capacity according to the position. Methods: Seventeen subjects participated in the study (male=7, female=10). The subjects performed Kegel exercise in two positions: sitting and hooklying. The order of exercise was conducted in a random order selected by the subjects to exclude the learning effect. The maximum voluntary ventilation (MVV) was measured using a spirometer. The vital capacity was measured according to the manual in the sitting position before the experiment. After each exercise, the vital capacity was also measured in the same way. One way repeated measures analysis of the variance (ANOVA) was used to compare the vital capacity according to the position, and a Bonferroni test was used for post hoc analysis. Results: Significant differences in vital capacity were observed after exercise than before exercise (p<0.05). Post-hoc analysis, however, revealed no difference in vital capacity according to the position (p>0.05). Conclusion: This study was a preliminary study to determine the vital capacity according to the Kegel exercise and two positions. Nevertheless, further study with several revisions of the number of subjects, duration, and time for intervention will be needed.
