  • Exercise and resveratrol supplementation exhibit anti-obesity functions in the long term but have not been fully investigated yet in terms of their early potential effectiveness. Mice fed with high-fat diet were categorized into control (Cont), exercise (Ex), resveratrol supplementation (Res), and exercise combined with resveratrol supplementation (Ex + Res) groups. In the four-week period of weight loss, exercise combined with resveratrol supplementation exerted no additional effects on body weight loss but significantly improved whole-body glucose and lipid homeostasis. The combined treatment significantly decreased intrahepatic lipid content but did not affect intramyocellular lipid content. Moreover, the treatment significantly increased the contents of mtDNA and cytochrome c, the expression levels of peroxisome proliferator-activated receptor gamma coactivator-1 alpha and its downstream transcription factors, and the activities of ATPase and citrate synthase. However, exercise, resveratrol, and their combination did not promote myofiber specification toward slow-twitch type. The effects of exercise combined with resveratrol supplementation on weight loss could be partly due to enhanced mitochondrial biogenesis and not to fiber-type shift in skeletal muscle tissues.

  • Exercise training (ET) and selenium (SEL) were evaluated either individually or in combination (COMBI) for their effects on expression of glucose (AMPK, PGC- $1{\alpha}$, GLUT-4) and lactate metabolic proteins (LDH, MCT-1, MCT-4, COX-IV) in heart and skeletal muscles in a rodent model (Goto-Kakisaki, GK) of diabetes. Forty GK rats either remained sedentary (SED), performed ET, received SEL, ($5\;{\mu}mol{\cdot}kg$ body $wt^{-1}{\cdot}day^{-1}$) or underwent both ET and SEL treatment for 6 wk. ET alone, SEL alone, or COMBI resulted in a significant lowering of lactate, glucose, and insulin levels as well as a reduction in HOMA-IR and AUC for glucose relative to SED. Additionally, ET alone, SEL alone, or COMBI increased glycogen content and citrate synthase (CS) activities in liver and muscles. However, their effects on glycogen content and CS activity were tissue-specific. In particular, ET alone, SEL alone, or COMBI induced upregulation of glucose (AMPK, PGC-la, GLUT-4) and lactate (LDH, MCT-1, MCT-4, COX-IV) metabolic proteins relative to SED. However, their effects on glucose and lactate metabolic proteins also appeared to be tissue-specific. It seemed that glucose and lactate metabolic protein expression was not further enhanced with COMBI compared to that of ET alone or SEL alone. These data suggest that ET alone or SEL alone or COMBI represent a practical strategy for ameliorating aberrant expression of glucose and lactate metabolic proteins in diabetic GK rats.

  • This study was carried out with 505(243 boys and 262 girls in the Sungnam area) high school students to investigate the effects of eating behavior and anthropometric variables of weight and height on excercise performance. General characteristics about subjects and eating behavior were surveyed by questionnaire, anthropometric data were collected using two methods. The weight and height of subjects in 1996 were measured, but the same data in 1995 were collected from health records of each student. Body fat content of subjects was measured by BIA(Body Impedance Analysis). The grades of exercise performance, which were evaluated by physical education teachers were collected from records of a physical strength test score of each subject. From these, the following result were found. Groups with different eating behaviors such as skipping meals, overeating, food preference for a specific food(milk, carbonated drink etc.) were significantly different in their weight and height and body fat contents. The growth rate of height in first and second grade boys was significantly higher than that for grade boys. The amount of weight gain from second grade to third grade was significantly more than that of other grades both for boys and girls. The mean of BMI was $21.66\pm{2.95}$ in boy, $21.50\pm{2.62}$ in girls. The percentage of body fat was $24.91\pm{6.55%}$ in boy $34.73\pm{4.88%}$ in girls. Amounts of body fat were significantly increased in third grade. The group with higher fat content and the higher BMI group had lower values of physical strength. And the ability to exercises perform decreased significantly by promotion of grade. The other variables such as degree of concern about weight control and preference of exercise, and frequencies of exercise per week were significant factors in body fat content and physical strength. As a countermeasure for these problems, nutrition and health education must be developed for adolescents and a practical, proper physical activity guidance campaign for them is necessary.

  • Purpose: The present study analyzed the contents of exercise programs for the elderly in Korean and foreign articles. Method: This study analyzed 27 Korean and 20 foreign exercise-related articles selected from Web DBs using keywords 'exercise', 'exercise program' and 'exercise effect'. The collected data were analyzed using SPSS 11.5 through descriptive statistics, $x^2$ test and Fisher's exact test. Results: In the description of population, random sampling and informed consents, foreign articles were higher than Korean articles. In research design, foreign articles randomized controlled trials (RCTs) higher than Korean articles. The contents of exercise programs in the Korean and foreign articles were aerobic, walking and stretching. On the effects of exercise programs in the Korean articles, walking showed the highest frequency in the physical strength as well as muscle strength, balance and flexibility. In the foreign articles, walking and stretching showed high frequency in physical strength. Conclusion: Contents significant in exercise programs for the elderly were walking and stretching. In addition, regular exercise had a positive effect on muscle strength, flexibility and balance in the elderly.

  • The aim of the study was to evaluate the effectiveness of exercise therapy on physical function of patients with anklyosing spondylitis (AS) through the systemic review and meta-analysis. The 54 studies were identified from computerized search of published researches on PubMed, Embase, CINAHL, PEDro, KISS, KERIS database until February, 2008 and review of reference lists. The main search terms were the combination "ankylosing spondylitis", "exercise", "spondyloarthropathy and exercise", "ankylosing spondylitis and physical therapy". The subgroup analysis was performed by the publication year, quality score, type of disease, content of intervention, intervention provider, type of intervention, method of intervention, intervention period and the point of outcome measured. Two reviewers independently selected trials for inclusion, assessed the quality and extracted the data. The result was as follows: The 10 trials were eligible for inclusion criteria, then the systematic review and meta-analysis was assessed on effectiveness of exercise therapy. The meta-analysis of 10 studies based on the random effect model showed that the exercise therapy was beneficial in treating the diseases (effect size .55; 95% confidence interval -.3.75~.61). The findings suggest that the exercise therapy would be appropriate to manage the physical function of AS with evidence based on Meta-analysis. Therefore, the exercise therapy supervised by physical therapist should be recognized as the essential approach to manage the AS and necessarily recommended to improve physical function.

  • This study was designed to investigate the effects of aerobic and /or Ca supplementation for six months on lipid metabolism and blood pressure in postmenopausal women. The subjects were healthy 29 women aged from 60 to 70 years old. They were divided into four groups: placebo and Ca supplementation group with and without exercise. The amount of Ca supplemented was 500mg a day. The frequency of doing exercise was three times a week and each time, it took 40 minutes to complete all the course of aerobic dancing programmed for old women. During the experimental period, the subjects ate their usual diets and the use of druge as well as additional exercise was prohibited. The results were summarized as follows. 1. Percent body fat and BMI were significantly decreased and the body weight tended to decreased due to aerobic dancing. 2. Serum lipids content tended to show only a slihgt changes due to Ca supplementation: serum triglyceride, total-chol, LDL-chol, FFA content tended to decrease but serum HDL-chol / LDL-chol ratio tended to increase after the experiment in Ca group. On the contrary, serum lipids level was not changed by exercise. 3. Blood pressure did not show any significant changes by Ca supplementation and / or exercise for 6 months in old women. 4. Serum Ca level of Ca group was significantly increased after experiment in Ca group (p<0.05) but not in Ex-Ca group. In summarization, it appeared that the aerobic dancing was a definite way to reduce percent body fat and BMI in postmenopausal women. On the other hand, Ca supplementation seemed to be able to induce favorable changes in serum lipids. However, any synergistic metabolic effects of exercise and Ca supplementation was not seen in this study. Further study is needed to elucidate the relationship between exercise and/or Ca supplementation and the changes in blood lipids profile as well as blood pressure more clearly.

  • The purpose of this study was to determine the effect of endurance training prior to occurrence of muscle atrophy on the mass, myofibrillar protein content and fiber crossectional area of atrophied hindlimb muscles of rats. Adult female Wistar rats were trained prior to occurrence of muscle atrophy induced by hindlimb suspension. Training began on the 1st day for 10min /day at 15m /min on a 0% grade, training exercise increased daily in time and intensity so that by the 4th week rats were running 60min /day, at 34m /min on a i3.5% grade. Wet weight and relative weight of soleus, plantaris and gastrocnemius muscle decreased significantly after seven days of hindlimb suspension. Wet weight and relative weight of soleus tended to increase and that of plantaris and gastrocnemius tended to decrease in the exercise group as compared to the control group. Myofibrillar protein content of soleus and gastrocnemius tended to increase and that of plantaris tended to decrease in the endurance trained group as compared to the control group. Fiber crossectional area of Type I, II fiber in soleus and plantaris muscle tended to increase in the exercise group as compared to the control group. Wet weight and relative weight of soleus. plantaris and gastrocnemius decreased significantly, myofibrillar protein content of soleus, plantaris and gastrocnemius increased in hindlimb suspended rats following endurance training as compared to the control group. There was no change in fiber type percentage and crossectional area of type I and II fiber in soleus muscle and that of type I and IIfiber in plantaris muscle decreased in the hindlimb suspended rats following endurance training as compared to the control group. Wet weight and relative weight of soleus and plantaris tended to increase, that of gastrocnemius increased significantly, myofibrillar protein content of soleus and plantaris muscle increased significantly and that of gastrocnemius tended to increase in the hindlimb suspended rats following endurance training as compared to sedentary rats following endurance training. Crossectional area of type I fiber of soleus muscle tended to increase. that of type I fiber of plantaris muscle increased significantly and that of type II fiber tended to increase in hindlimb suspended rats following endurance training as compared to sedentary rats following endurance training. The results suggest that endurance training prior to occurrence of muscle atrophy can attenuate the decrease of mass, myofibrillar protein content and fiber crossectional area induced by hindlimb suspension.

  • Purpose: To summarize and review the methodological quality of the evidence from trials examining the effectiveness of physical exercise in patients undergoing allogeneic hematopoietic stem cell transplantation (Allo-HSCT). Methods: Six randomized clinical trials (RCTs) were identified, reviewed for substantive results, and assessed for methodological quality. Results: Six trials met all methodological criteria on the modified Jadad score above 3 out of 5 points. Failure to blind the outcome assessor, and failure to describe the method of blinding of outcome assessor appropriately were the most prevalent methodological shortcomings. Various exercise modalities have been applied, differing in content, frequency, intensity, and duration. Positive results have been observed in part for a diverse set of outcomes, including physical and psychological performance. Conclusion: The trials reviewed in this study were of moderate methodological quality. They suggest that exercise in patients undergoing Allo-HSCT may be safe and feasible, and in part patients benefit from increased physical performance both during and after transplantation. Future RCTs should use larger samples, appropriate comparison groups, and a standard of outcome measures, and examine what kind of exercise intervention (aerobic vs. resistance vs. combined) is the most effective for Allo-HSCT patients. It would be necessary to define contraindication for exercise to guarantee its safety.
