The aim of the present investigation has, been to evaluate the depletion pattern of the supercompensated glycogen of hindlimb muscles during strenous exercise in rats. The plan of the maximizing muscle glycogen stores is based on the fact that a glycogen-depleted muscle by exercise will have an increased avidity for glycogen when exposed to a high carbohydrate diet. The glycogen concentration of soleus, red gastrocnemius and plantaris muscle, and liver was measured at 0, 30 and 60 minutes during treadmill exercise. The experimental animals were divided into 5 group - Normal(N), Control(C), 1Hour(1HR:after 1hour of glucose ingestion), 2Hour(2HR:after 2hour of glucose ingestion) and Exercise-1Hour(EX-1HR:glucose ingestion after 1 hour of preloading treadmill exercise)group - for glycogen storage study. The glycogen concentration of soleus, red gastrocnemius and plantaris muscles in N group was $4.57{\pm}0.34$, 5.11+0.24 and $6.55{\pm}0.20mg/gm\;wet\;wt.$, respectively. The glycogen concentration of soleus and red gastrocnemius in EX-1HR group were about 1.9 and 1.8 times than that of N group, respectively, but the concentration of plantaris was not higher than that of N group. The glycogen concentration of liver in N group was $41.0{\pm}1.47mg/gm\;wet\;wt.$ and the concentration of the overnight fasted C group was only 2.9% of the value of N group. The level of glycogen concentration of liver in the other glucose ingested groups(1HR, 2HR, including EX-1HR) was within 19 - 32% of that of N group. The blood glucose concentration of EX-1HR group was higher than that of N group, the plasma free fatty acid concentration of C and 2HR group was higher than that of N group, and the plasma insulin concentration of EX-1HR group was higher than that of N group. The concentrations of supercompensated glycogen of soleus and red gastrocnemius were rapidly decreased during 30 minutes of exercise but there was almost no changes of the concentration during the other 30 minutes of continuing exercise. The concentration of N group during 30 minutes of exercise was decreased but more slowly than those of EX-1HR group. The remaining level of glycogen after 60 minutes of exercise in EX-1HR group was higher than that of N group. Taken together, the mobilization of endogenous muscle glycogen at the first stage of exercise was proportioned to the initial level of glycogen concentration, and later on, when exercise continued, the muscle glycogen level was stabilized. And the remaining level of supercompensated muscle glycogen after 60 minutes of exercise was higher than that of normally stored glycogen level. The mobilization of the glycogen stroed in slow and fast oxidative muscle fibers is faster than in the fast glycolytic muscle fibers during strenous exercise.

Purpose. The purposes of this study were to examine the effectiveness of a behavioral intervention program combining pelvic floor muscle exercise with bladder training for urinary incontinence and also to conduct follow-up assessment after self-training. Methods. This study was conducted using a non-equivalent control group, pretest-posttest design. The subjects were 60 middle-aged women(control group, n=30; intervention group, n=30) who experienced an episode of urinary incontinence at least once a week. The program was run over a 4 week period (once a week) and composed of urinary incontinence education, pelvic floor muscle exercise, and bladder training. Results. Overall, there was a significant difference in urinary incontinence symptoms and psycho-social well-being related to urinary incontinence between the treatment and control group. Of the variables, weekly leakage frequencies, leakage amounts on each occasion, leakage index, frequencies of nocturia, and quality of life were significantly different between the groups. Follow-up assessment (9th week) indicated that overall incontinence symptoms and psycho-social well-being were significantly different between the posttest and follow-up assessments. Most variables of incontinence symptoms and psycho-social well-being were significantly improved at follow-up assessment versus posttest. Conclusions. The program was voerall effective in terms of relieving symptoms and improving psych-social well-being related to urinary incontinence, and this effect continued after a 4-weeks self-training period. In the respect that this is a community-based application study, the results can be meaningful and applicable.

Purpose: The purpose of this study was to investigate the relationships among health behavior, wellness condition, and stage of change in health behavior by risk of cardiocerebrovascular diseases (CVD) in male office workers. Methods: A total of 205 male office workers participated in the 2017 National Health Examination at a manufacturing/ R&D business in Seongnam and completed self-reported questionnaires. Results: There were significant differences in health behavior scores by risk of CVD (F=4.78, p=.009) and statistically significant differences in no smoking (F=5.86, p=.003), exercise (F=5.49, p=.005), and health checkup (F=4.39, p=.014). There were statistically significant differences in health behavior (t=-4.14, p<.001) and wellness condition (t=-2.61, p=.010) by the stage of change in health behavior. Health behavior had a weak positive correlation with wellness condition (r=.36, p<.001). Logistic regression analysis showed that, when adjusted for age and employment period, the probability of becoming attention or risk group was 11% lower for quitting smoking (OR 0.89, 95% CI 0.81~0.97, p=.006) and 18% lower for regular exercise (OR 0.82, 95% CI 0.70~0.95, p=.009). Conclusion: The direction of health management at the workplace should be changed to promote the wellness of all workers, not the management of the disease, and a health promotion program should be continued to emphasize health behaviors such as smoking cessation and regular exercise.

This study was aimed to implement and evaluate worksite nutrition counseling for industrial workers with hyperlipidemia in Kyung-buk area. Forty-six subjects consisted of 41 men and 5 women who were diagnosed hyperlipidemia though health examination had their average age, 40.3$\pm$ 6.0 and half of them were office workers and one third labor workers. Twenty-eight subjects had fatty liver with or without other complications and six had gastric problems. The subjects were interviewed using questionnaires on food habit, food frequency, smoking, drinking and exercise, and they were given nutrition counseling which was continued for 7 months. Desirable food selections were practiced using foods or food models and various written materials individually or as group during lunch times and breaks. After counseling, smoking and drinking were reduced and exercise and food habits were improved. Average levels of initial serum total cholesterol(T-Chol), HDL-cholesterol(HDL-Chol) and triglyceride(TG) were 214$\pm$ 44, 45.07$\pm$ 7.14 and 281$\pm$ 13mg/dl respectively and were not changed significantly except 2.30$\pm$ 7.04mg/dl increase of HDL-Chol(p<0.1) after nutrition counseling. However, subjects who improved their food habits and smoking, drinking and exercise habits had higher tendency to have reduced serum T-Chol and TG levels compared with those who drank less. Food habit score was negatively correlated with serum TG levels(r=-0.378, p<0.01). It is concluded that an efficient and regular nutrition counseling by dietitian at worksite is beneficial for health of industrial workers.

The present study aims to provide efficient regimen by means of the Oriental medicine tool to measure Yangseng developed to fit the situation of Korea. For this purpose, the elderly people aged older than 65 were selected and their level of Yangseng was compared and analyzed depending on their perception of health. From the study, following conclusions could be drawn: 1. The total subject of study were 763 consisting mostly of the illiterate and spoused with disease but without leisure activities. 2. Most of the subjects were found to have little confidence with their health. With regard to their level of Yangseng, higher points were rated in morality yangseng, followed by activities & rest, diet, mind yangseng, sleep, seasonal yangseng, exercise and sex life in order. 3. By socio-demographic characters for the group with confidence in health, there were more male than female, with spouse, disease and leisure activities currently. In the group without confidence in health, there were more female, without spouse and leisure activity but with disease presently. 4. As for the level of Yangseng in the group with confidence in health, higher points were recorded in morality yangseng, followed by activities & rest, mind yangseng, diet, sleep, exercise and sex life in order. In case of the group without confidence in health, higher points were recorded in morality yangseng, followed by activities & rest, diet, mind yangseng, sleep, exercise and sex life in order. From the above outcomes, it would be necessary to motivate the subjects to have a renewed concept for health and efficient regimen. Continued and repeated eforts should be made to fill the gap in the study using the tool to measure Yangseng of the elderly people.

As the aging population has increased, the silver generation is getting to account for the considerable percent of economic activities and becomes the main body of production and consumption. Although the economic activity of silver generation is increased, the development of silver contents for the leisure activities is still not revitalized. The serious silver contents and the easy-to-use interface are very important because the silver generation is relatively weaker than young people in perception, studying, and exercise, and is fragile in mobility and vitality. This paper suggests methods to develop sensory bicycle, gate ball, and mole game contents haying lower body exercise effects for the silver generation to utilize leisure and maintain health. Along with fun as games, functional design factors suitable to the cognitive ability and bodily activity ability of the silver generation were considered and through sensory intefaces that are easy for the silver generation to use and customized progressing methods complying with individual characteristics, it was attempted to induce continued interests and lower body exercise effects.

The development of acidosis during intense exercise has traditionally been explained by the increased production of lactic acid which causes the release of a proton and the formation of the acid salt sodium lactate. Through this explanation, when the rate of lactate production is high enough to exceed cellular proton buffering capacity, cellular pH is decreased. This biochemical process has been termed lactic acidosis. This belief has been an interpretation that lactate production causes acidosis and fatigue during intense exercise. However, this review provides clear evidence that there is no biochemical support for lactate production causing acidosis and fatigue. Metabolic acidosis is caused by an increased reliance on nonmitochondrial ATP turnover. Lactate production is essential for muscle to produce cytosolic $NAD^+$ to support continued ATP regeneration from glycolysis. In addition, Lactate production consumes protons. Although lactate accumulation can be a good indirect indicator for decreased cellular and blood pH, that is not direct causing acidosis.
