This study was conducted to determine whether low intensity regular exercise following dexamethasone treatment could attenuate steroid-induced muscle atrophy. Method: 36 Wistar-rats(90-110g) were divided into six groups: control group(C), dexamethasone treatment group(D), sedentary group after normal sedentary period(C+S), sedentary group after dexamethasone treatment period(D+S), exercise group after normal sedentary period(C+E), and excercise group after dexamethasone treatment period(D+E). D, D+S, and D+E groups received dexamethasone injection(5mg/Kg) for seven days whereas C, C+S, and C+E groups received normal saline injection. Both C+E and D+E groups ran on a treadmill for 60 minutes/day(20minutes/4hours) at 15m/min and a 10$^{\circ}$grade for seven recovery days. Result: Post-weight(body weight before muscle dissection) of D group significantly decreased by 16.03%, and that of D+E group significantly increased by 15.51% compared with pre-weight(body weight before steroid treatment). TypeII muscle(plantaris and gastrocnemius) weights of D group were significantly lower than those of C group. Myofibrillar protein contents of typeII muscles of D group tended to decrease comparing with C group. In D+E groups, body weights and relative weights of typeII muscles(muscle weight(mg)/post-weight(g)) tended to increase comparing with D+S group. Conclusion: It is suggested that steroid- induced muscle atrophy can be ameliorated through low intensity regular exercise after dexamethasone treatment.

This study was performed in oder to investigate to dietary behavior, perceived stress and their correlations of University students. The number of subjects was 549 and the results of this study are as followed: Only 13.9% of students-20% of male students, 10% of female students-exercise regularly. Regular exercise and health condition had no statistical relationship in this study. 83.9% of subjects had experience of alcohol drinking (19.4% of male students, 7.3% of female students). Many students replied that they drink alcohol 1∼2 times per a week. 24.4% of students-only 2.6% of female students-were smoking and great number of smokers were drinking also. The BMI of 46.7% of subjects were in normal range. 48.2% were in under weighted and 5.1% were in over weighted or obesity. The stress factor of University students were analyzed into 12. Inner stress factors like as identity, coursework, friendship, health problem were more potent in female students than male. Among the health related habits, disease itself had a great effect on many stress factors but regular exercise had a little.

The purpose of this study was to compare the changes in PLP concentrations induced by regular, moderate, and abrupt, high-intensity exercise in the plasma and tissues of vitamin B6 deficient and normal rats. Forty-eight rats were fed either a vitamin B6 deficient (-B6) diet or a normal (+B6) diet for 5 weeks and were subdivided into 4 groups:non-exercise(NE) group: regular, moderate-intensity exercise (RME) group; abrupt, high-intensity exercise (AIE) group; abrupt, high-intensity exercise and recuperation(IRE) group. The RME group was exercised on treadmill ($10^{\circ}$, 0.5-0.8km/h) for 2 hours just before sacrifice at the end of 5th week on the diet and the IER group was recuperated for three days on the diet after being exercised like the AIE group. Pyridoxal 5 -phosphate(PLP) levels were compared in the plasma, liver and skeletal muscle of the rats. Plasma PLP concentration tended to decrease in -B6 rats and tended to increase in +B6 rats with AIE. Plasma PLP concentration in both +B6 rats with AIE and no change in both -B6 and +B6 rats with RME. Muscle PLP concentration decreased in +B6 rats, showed no change in -B6 rats with AIE. Muscle PLP concentrations in both +B6 and -B6 rats did not change with RME. Plasma PLP, liver PLP and muscle PLP concentration of IER returned to those of NE in both +B6 and -B6 rats. These results suggest that changes in PLP concentration in plasma, liver and muscle occur with exercise and are affected by exercise intensity and vitamin B6 status. These changes may be due to interorgan redistribution of PLP.

A case study on the relationship between an exercise program and the exercise cognition of the aged persons at a community center for the elderly in Seoul was carried out to get some basic data for a better exercise program. The frequencies and time of exercise and the exercise cognition before and after the exercise program were compared. The program included exercise training and education 2 or 3 times a week for three months with 6 different kinds of exercise machines. 32 persons were interviewed. and the results. which were analyzed using SPSS package program. showed frequencies. percentages and Wilcoxon rank sum test. The following conclusions were obtained: 1. After the exercise program. the exercise frequency and time were increased. and the leisure life was changed positively. 2. $96.9\%$ of the interviewees understood well the necessity of the exercise, and the most reasonable reason why they do exercise was to keep their physical strength and health. And more persons of the group who do exercise everyday than those of the group who do not exercise everyday. felt that they are healthy. 3. It was responded that the most important factor to promote the exercise activity of aged persons was to provide exercise facilities and rooms. and exercise trainers. Accordingly. the exercise facilities and rooms. and exercise trainers should be provided, and various exercise programs should be developed. for the regular exercise of aged persons in their lives. Therefore. qualitative life and well-being of aged persons should be improved.

Objectives : To determine the relationship between exercise and the incidence of type 2 diabetes in an impaired fasting glucose group. Methods : This prospective cohort study was conducted in 19,440 men and 4,297 women, aged 30-69 years, with impaired fasting glucose at baseline who had undergone biennial medical evaluation through the National Health Insurance Corporation from 2000 to 2004. Impaired fasting glucose was defined as fasting glucose of 100 to 125 mg/dl and the subjects were divided into 3 groups depending on weekly exercise frequency. Multivariate logistic regression analysis was used to evaluate the association between the baseline exercise status and incidence of type 2 diabetes. Results : During the 4-year follow-up, a total of 3,239 men and 283 women developed type 2 diabetes, a cumulative incidence of 16.6% for men, and 6.5% for women. Also, 1,688 men (21.2%) and 127 women (15.2%) developed type 2 diabetes in the obese group. The adjusted relative risk (RR) of developing type 2 diabetes in non-exercising men was significantly higher than exercising men regularly (RR= 1.375, 95% CI=1.236-1.529)(p<0.0001), and the RR for non-exercising women was higher than exercising women regularly (RR=1.124, 95% CI=0.711-1.778). The RR for non-exercise men/women in the obese group was 1.571 (95% CI=1.351-1.827)(p<0.0001)/1.869 (95% CI=0.846-4.130). Conclusions : Regular exercise is effective in preventing type 2 diabetes in people with impaired fasting glucose, and particularly in obese people. People with risk factors for diabetes should participate in a regular exercise program.

Purpose : The purpose of this study was to investigate the effectiveness of pain release through the four weeks aquatic exercise among the female subjects aged above 50 and who suffered from arthritis. Methods : The assessment was validated by blood analysis which measured the fluctuations of Erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and Rheumatoid factor(RF). Among the 50 subjects of this experiment, the control group has only taken a regular treatment from the clinic and the other experimental group has done aquatic exercise. The experimental group has practiced the aquatic exercise 50 minutes a day for one month excluding the weekends. Results : Blood analysis revealed that ESR was decreased in both the control group and the experimental group and the major effect of CRP was diminished only in the experimental group. No significance of RF was found in both the control group and the experimental group. Conclusion : These results indicate that the aquatic exercise is an effective treatment for arthritis that is compatible with the similar results from the previous studies. In line with this, the aquatic exercise program can provide an effective treatment and control of the disease with the arthritis patient. Accordingly, the regular basis aquatic exercise proved to be quite satisfactory treatment in this regard and we contend that it is vital for the arthritis patients.

Many studies have emphasized the importance of resistive exercise to maintain a healthy human body, particular in prevention of weakening of physical strength. Recently, some studies advocated that an application of vibration as a supplementary means in a regular training was effective in encouraging physical strength. Aim of the current study was, therefore, to identify if an application of vibration in a resistive exercise was effective in encouraging physical strength as that in a regular training. A 3-dimensional virtual lower extremity model for a healthy male and virtual leg-press model were generated and synchronized. Dynamic leg-press exercises on a slide machine with/without extra load and on a footboard with vibration as well as on a slide machine with extra load were analyzed. The results of the current indicated that the application of the vibration on the dynamic leg-press exercise might be not greatly effective in encouraging physical strength, compared with the dynamic leg press exercise with extra load. It was, however, thought that the application of the vibration might be helpful to elderly individuals because the reduced maximum muscle strength appeared by the effect of the vibration may avoid a muscular spasm, which can be driven from a high muscle strength sometimes produced during the leg-press exercise with extra load.

PURPOSE: The purpose of this study is to investigate the effects of the angles of the knee and heel-off on the muscle activity during a bridge exercise. METHODS: 15 healthy adult men and women with the balance ability and joint working range required for performing a bridge exercise participated in this study, in which $120^{\circ}$, $90^{\circ}$ and $60^{\circ}$ angles of the knee-flexion and heel-off were applied during the bridge exercise. RESULTS: Our data showed that there were significant differences in muscle activities of elector spinae and rectus abdominis when $120^{\circ}$ and $60^{\circ}$ angles of the knee were applied, of internal oblique when $120^{\circ}$ and $60^{\circ}$ were applied, and external oblique when $90^{\circ}$ and $60^{\circ}$ were applied. When heel-off was applied, there were significant differences in muscle activities of elector spinae and rectus abdominis when $120^{\circ}$ and $60^{\circ}$ were applied, of internal oblique when $120^{\circ}$ and $60^{\circ}$ were applied, and external oblique when $90^{\circ}$ and $60^{\circ}$ were applied. CONCLUSION: In this study on an application of heel-off to the bridge exercise, we showed that the effect of the angles of the knee on the muscle activities of elector spinae, rectus abdominis, internal oblique and external oblique were all similar to the regular bridge exercise, but overall muscle activities were increased with heel-off when compared with the regular bridge exercise.

Coronary artery disease(CAD) is associated with a high risk of recurrence and an increased mortality rate upon recurrence. Consequently, there is a need for continuous health behavior recommendations from medical staff. Therefore, a study was conducted on 219 patients hospitalized for coronary angiography. The study aimed to investigate the influence of medical staff recommendations on exercise adherence among CAD patients. In conclusion, regular exercise(RE) recommendation(OR 3.52, p=.036) and dietary advice from medical staff(OR 6.48, p=.022), having high exercise self-efficacy(OR 1.36, p=.001) positively affected RE adherence. Therefore, medical staff should strengthen personalized recommendations for RE and healthy diets, as well as develop exercise self-efficacy enhancement programs to encourage patient participation. Future research is recommended to explore the impact of the degree and method of medical staff recommendations on self-management practices among CAD patients.
