To enhancing the exercise effect, exercise management systems are introduced and generally used. They create the proper exercise program through exercise prescription after determining the personal body status. When the exercise programs are created, they will consider $2weeks{\sim}3months$ period. And, existing exercise programs cannot respect with personal exercise habits or exercise period which are changing variedly. If exercise period is long, it can be caused inappropriate exercise about user current status. To solve these problems in legacy systems, this paper proposes a Context Aware Exercise Model (CAEM) to provide the exercise program considering the user context. Also, we implemented that as Intelligent Fitness Guide (IFG) System. The IFG system is selectively received necessary measurement values as input values according to user's context. If exercise kinds, frequency and strength of user are changing, that system creates the exercise program through exercise optimization algorithm and exercise knowledge base. As IFG is providing the exercise program in a real time, it can be managed the effective exercise according to user context.

The objective of this study was to analyze the factors affecting the stages of change of exercise in middle-aged men who work. 170 middle-aged men who work surveyed, 40 to 59 years old, is residing, Chung-Buk and Chung-Nam province, who understand the purpose of this study and agree to participate in this study. This study data is analyzed by using frequency, percentage, standard deviation, t-test, 𝑥² test and Logistic regression analysis. The study show that the exercise self-efficacy(𝛽=.965, p=.003) and the perceived health status(𝛽=.805, p=.025) among middle aged men who work have an effect on the stages of change of exercise meaningfully. That is, the exercise self-efficacy of middle aged men who work who have exercise behavior is 2.6 times higher than middle aged men at work who don't have exercise behavior, and the perceived health status is 2.2 times higher. This study suggests that the development of better exercise practice for middle aged men who work should be aimed at promoting exercise self-efficacy and perceived health status, Based on this, it is necessary to find ways to operate exercise programs at the workplace and community level.

The relationship between exercise intensity, oxidative stress and antioxidant status has been studied in sixteen trained male athletes aged 20-25years. Subjects performed 30-40minutes of treadmill running at 65% of VO2 max(high intensity exercise). Blood samples were taken before and immediately after two exercise bouts for measurement of blood antioxidants, indices of lipid peroxidation and susceptibility of crythrocyte to peroxidation. Plasma concentrations of cholesterol(7.3%), vitamin C(7.5%) and uric acid(2.1%) were elevated a little after exercise at 65% of VO2 max(13.7%)were significantly high than before exercise(p<0.05). However, these exercise-induced changes could be partly due to significant decreases in plasma volume which occurred after both exercise bouts(p<0.05). Plasma volume decreased 5.85$\pm$2.06% and 11.25$\pm$2.87% with exercise at 65% and 85% of VO2 max, respectively. The erythrocyte susceptibility to peroxidation after exercise at 65% of VO2 max was unchanged compared with the value before exercise, whereas after exercise at 85% of VO2 max, it was significantly higher than after exercise at 65% and 85% of VO2 max as well as before exercise(p<0.05). A significant increase at 85% of VO2 max, it was significantly high than after exercise at 85% of VO2 max (29.10$\pm$4.76ug/g Hb)when compared with the level before exercise (24.61$\pm$3.45ug/g Hb)(p<0.05). The results suggest that exercise-induced changes in plasma levels of lipid peroxide and antioxidant need to be evaluated, taking the shift in plasma volume into consideration. Also, exercise at high intensity corresponding to 85% of VO2 max alters the erythrocyte antioxidant status in relation to exercise-induced of oxidative stress.

This study investigated the effect of vitamin $B_6$ deficiency on antioxidant enzyme activities and lipid profile in rats with exercise-induced oxidative stress. Forty eight rats were fed either a vitamin $B_6$ deficient diet (B6-) or a control diet (control) for 4 weeks and then subdivided into 3 groups: pre-exercise (PreE); post-exercise (PostE); recess after exercise (recessE). Compared to those of control group, plasma catalase and hepatic cytosol superoxide dismutase (SOD, EC 1.15.1.1) activities of B6- group were lower regardless of exercise. The ratio of reduced glutathione/oxidized glutathione (GSH/GSSG) of B6 - group was lower in PreE and there was no difference between PostE and recessE. The level of malondialdehyde (MDA) of B6- was significantly higher in PreE and PostE. High-density lipoprotein-cholesterol (HDL-C) level of B6- group was lower regardless of exercise. Atherosclerotic index of $B_6$- group was higher in PreE and there was no difference between PostE and recessE. It is suggested that a reduction in antioxidative status caused by vitamin $B_6$ deficiency may be aggravated under exercise-induced oxidative stress.

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.

Purpose: This study was to investigate impacts of daily habits, health status and health promoting behavior on prevalence of irritable bowel syndrome (IBS) among female high school students. Methods: The survey was conducted from 526 female students in high school. Rome III criteria was used to diagnose IBS. Data of daily habits, health status, and health promoting behavior were collected through self-administered structured questionnaires. Results: The prevalence of IBS was 25.7%. Compared to the non-IBS, the IBS group scored significantly lower in exercise time, sleeping time, four dimensions of health status (physical, emotional, social, spiritual health) and management of relationship and stress in health promoting behavior. Risk factors influencing IBS were exercise time, physical health and emotional health status. Conclusion: The results of this study suggest that nursing interventions and education programs are important to be developed, while considering exercise, health status and health promoting behaviors for female adolescents in order to manage their IBS.

BACKGROUND/OBJECTIVES: Successful recovery of an animal from exercise is essential, especially prior to the next exercise session. This study was conducted to find an effective exercise-to-rest period ratio for the restoration of energy sources and replenishment of anti-oxidative status in tissue after exercise. MATERIALS/METHODS: Thirty-two rats were assigned to either non-training or training exercise groups for 5 weeks. After that period, the two groups were subdivided into four smaller groups: non-exercise (NE), exercise 0.5 hour and rest 1 hour (ER0.5:1), exercise 1 hour and rest 1 hour (ER1:1), exercise 2 hours and rest 1 hour (ER2:1). RESULTS: In the training group animals and compared to the NE group, the levels of plasma glucose after the rest period were significantly high in all ER groups but highest in the ER2:1 group. Similarly, the liver glycogen level was highest in the ER2:1 group. The plasma FFA level reached the highest level in the ER2:1 group but was similarly high in the ER0.5:1 group. Liver TG level was unchanged in the ER2:1 and ER1:1 groups but was significantly high in the ER0.5:1 group. Muscle TG levels were decreased in all three ER groups. Plasma protein levels were significantly high in the ER2:1 and ER0.5:1 groups. In both training animal and non-training animals, the liver protein levels did not change significantly between the NE and ER groups, irrespective of the exercise-to-rest ratio. In the training animal group, muscle protein level was significantly low in the ER2:1 and ER0.5:1 groups. The activity levels of superoxide dismutase and catalase, as well as the malondialdehyde concentration, were not significantly different between NE and ER groups, irrespective of the exercise-to-rest period ratio. CONCLUSIONS: These results indicate that animals provided with a 0.5:1 to 1:1 exercise-to-rest period ratio can restore their muscle energy sources and recover their anti-oxidative defense system.

To investigate the status of farmers health management for health promotion, and for checking the effect of village health care center during 1 year, 746 subjects were selected with cluster method in 8 provinces of Korea. The most frequent group was 40th of age (39%) : elementary school graduates (32%) The self-conscious of health status tested with CMI (Cornell Medical Index) questionnaire, the subjects in the village of health care center had lower health status than those of conventional village. The farmers living in the village with health care center had longer agricultural work (p＜0.05) and more frequency of spraying pesticides in the fields. The subjects of living the village of health care center were frequently exercise (34%) with health appliance use methods (30%), but the duration time of exercise was similar, Dietary habits and agricultural work condition were similar between two groups. For the fatigue recovery, steeping and bathing were most favorite methods, but exercise was lowest. It was significantly different between 2 groups the fatigue recovering methods, the subjects of village with health care center were more doing exercise (p＜0.01), less sleeping (p＜0.01) than those of conventional village. The working condition of self-estimated of farmers was not good, only 8.7% was thought pleasant condition. Of the various health factors, exercise, nutrition, and working situation would be more important. Considering on farmers exercise, it was very weak point for health management. The foundation and leading of the Farmers health care center was encouraged to farmers. For more effective operations, the experts education, easy and funny exercise program, and health promotion committee for administrators would be needed. The better systemic and continuous exercise programs should develop for associating livelihood. Funding for this project provided by the ministry of health and welfare of Korea.
