In the present work we investigated the effect of regular physical exercise on the activities of erythrocyte antioxidant enzyme, plasma total radical-trapping antioxidant potential(TRAP) and plasma level of lipid peroxidation(malondialdehyde, MDA) in 64 healthy male, aged 34-67 years. The study population were divided in two groups: small amount of exerciser(exercise time less than 10min/d) and moderate amount of exerciser(exercise time more than 20min/d) according to their physical exercise habits measured by a questionnaire. Erythrocyte superoxide dismutase(SOD), glutathione peroxidase(GSH-Px) and catalase(CAT), plasma TRAP, as well as plasma MDA were determined. Erythrocyte GSH-Px and plasma TRAP were higher in moderate amount of exercisers than those in small amount of exercisers by 17% and 26%, respectively. No significant differences were observed in erythrocyte SOD, CAT and plasma MDA between the two groups. Mean exercise time was positively correlated with the erythrocyte GSH-Px activity and plasma TRAP significantly. The results would sugest that regular moderate exercise enhances antioxidant defences against reactive oxygen species and may increase the likelihood of a healthier life span.

Purpose : This study was to explore the effects of knee joint taping exercise on muscle strength, bone mineral density, pain and IGF-1 in blood of elderly women with knee Osteoarthritis. Methods : Thirty elderly women with knee osteoarthritis were divided into three groups: the taping with exercise group (n=10), the regular exercise group (n=10) and control group (n=10). Participants' muscle strength, bone mineral density, pain and IGF-1 in blood were measured three times : before exercise, after 6 weeks, and after 12 weeks. Results : Participants in both exercise (taping & non-taping) groups showed improvement in muscle strength, bone mineral density, pain and IGF-1 in blood after 6 and 12 weeks compared to before exercise. In particular, the taping exercise group had a greater effect on muscle strength than the regular exercise group. Conclusion : Both exercise programs considerably improved muscle strength, bone mineral density, reduced pain and IGF-1 in blood in elderly women with knee Osteoarthritis. The knee joint taping exercise is perhaps a better exercise to improve muscle strength than the regular exercise in treating elderly women with knee Osteoarthritis

The purpose of this study is to examine the effects of sleep pattern on regular exercise and to examine mediating effect of subjective health status in the relationship between sleep pattern and regular exercise of older people. For the purpose of the study, older people aged over 65 years old who participated in 2020 Social Survey conducted by Statistics Korea were analyzed. Multiple regression analyses were used and significance of mediating effect was examined using Sobel test for 4,567 older people. Results of the analyses showed that sleep pattern had a significant effect on regular exercise of older people. That is, having an appropriate sleep increased the possibility of doing regular exercise, so the direct effect of sleep pattern on regular exercise was found. Sleep pattern had a significant effect on subjective health status, so older people having an appropriate sleep perceive their subjective health status more positively. As for the mediating effect, subjective health status had partial mediating effects in the relationship between sleep pattern and regular exercise of older people. Results of this study show that sleep pattern of older people should be considered in intervention for improving practicing regular exercise.

Methods: This study surveyed 500 female students attending a university to answer to self-reported questions using a questionnaire from May 3 to May 22 2010 and used 462 copies of the responses except insincere ones for the final analysis. Results: Of the 462 subjects, 30.7%(142) did regular exercise more than 3 times a week. As a result of the univariate analysis, there were relations between drinking, need of Exercise, attention to health, health habits, perceived behavior control and intention of exercise, and regular exercise. As a result of the multiple Logistic regression, there was a statistically significant relation between regular exercise and perceived behavior control and intention and drinking. Conclusion: This study identified that there were relations between drinking, perceived behavior control and intention of female college students and their regular exercise. Therefore, to promote their regular exercise, it is suggested that educational programs which consider such factors should be developed.

Purpose: The purpose of this study was to investigate gender related factors that influence regular exercise adherence in patients with coronary artery disease. Methods: This secondary analysis study used data from the 2013~2015 Korea National Health and Nutrition Examination Survey (KNHANES). Three hundred and eighty patients over 20 years of age and having coronary artery disease were selected for this study. Measures included questions about regular exercise, general characteristics, health behaviors, and health status. Data were analyzed using descriptive analysis, Rao-Scott $x^2$ statistic, and multiple logistic regression analysis with the SPSS 21.0 program. Results: The results were as follows. Men did more regular exercise than women (58.8% vs 40.1%). The multivariate-adjusted Odds Ratios (OR) for regular exercise adherence in men were 2.93 (95% CI: 1.39~6.17) for non smokers and 3.06 (95% CI: 1.53~6.13) for men with 0 to 1 comorbidities. Women had a high odds ratios of 0.38 (95% CI: 0.18~0.82) for not using alcohol and 2.10 (95% CI: 1.03~4.29) for no back pain. Conclusion: To improve regular exercise adherence in patients with coronary artery disease, it is necessary to develop different approaches considering gender.

Endothelial progenitor cells (EPCs) are known to play an important role in the repair of damaged blood vessels. We used an endothelial progenitor cell colony-forming assay (EPC-CFA) to determine whether EPC numbers could be increased in healthy individuals through regular exercise training. The number of functional EPCs obtained from human peripheral blood-derived AC133 stem cells was measured after a 28-day regular exercise training program. The number of total endothelial progenitor cell colony-forming units (EPC-CFU) was significantly increased compared to that in the control group (p=0.02, n=5). In addition, we observed a significant decrease in homocysteine levels followed by an increase in the number of EPC-CFUs (p=0.04, n=5), indicating that the 28-day regular exercise training could increase the number of EPC colonies and decrease homocysteine levels. Moreover, an inverse correlation was observed between small-endothelial progenitor cell colony-forming units (small-EPC-CFUs) and plasma homocysteine levels in healthy men (r=-0.8125, p=0.047). We found that regular exercise training could increase the number of EPC-CFUs and decrease homocysteine levels, thus decreasing the cardiovascular disease risk in men.

Purpose : The purpose of this study is to analysis effects of resistive exercise on cardiopulmonary fitness and cerebral artery blood flow velocity. Methods : Ten healthy university students had done resistive exercise without aerobic exercise over one year participated resistive exercise group and ten general university students, then were calculated oxygen consumption ($VO_2$) and respiratory exchange rate($VO_2/VCO_2$). After a week, they were measured Transcranial Doppler Ultrasonography(TCD) at moderate exercise(HRmax 50%), maximal exercise (HRmax 100%) for taking cerebral blood flow velocity. Results : In the comparison between groups, resistive exercise group showed significant higher oxygen consumption and lower respiratory exchange than controls(p<0.05). In resistive exercise group, oxygen consumption was significant negative correlation with cerebral artery pulsatory index(p<0.05). but, oxygen consumption was significant positive correlation with systolic blood flow velocity in controls(p<0.05). Conclusions : After considering all the factors, important value in resistive exercise is regular participation and help us increasing contingency response ability.
