The purpose of the present investigation was to determine the effect of combine exercise on C-reactive protein(CRP) and adiponectin, and to asses whether combine exercise-induced changes in insulin resistance could be explained in part by changes in these in these inflammation markers. Twenty two participants (BMI >95 percentile for age and sex) were allocated exercise group(n=12) and control group(n=10). Subjects had their body shape, body composition, glucose. insulin, HOMA-IR, CPR and adiponectin levels measured. Modest improvements in body composition, insulin resistance markers were observed, however, adiponectin and CRP did not changes. These data suggest that adiponectin and CRP is not a contributory factor to the exercise-relateted improvements in insulin resistance. Additional studies are needed to assess the effects of different duration, modes and intensities of exercise on inflammation markers.

The purpose of this study was to analyze the effect of a 12 week aerobic resistance training circuit program on the health-related fitness, blood lipids, and cortisol in obese postmenopausal women. The subjects for the study were twenty obese postmenopausal women composed of the exercise group (n=10) and "no exercise" control group (n=10). The aerobic resistance training circuit program was conducted for 70 minutes 3 times a week for 12 weeks, in which the aerobic exercise consisted of 5 items each composed of 5 sets of aerobic exercise at 50-70% HRmax intensity for 1 minute for a total of 25 minutes and the resistance exercise consisted of 8 items conducted for a total of 25 minutes at 40-60% intensity of 1RM). In the exercise group, the body weight and BMI significantly decreased and the 20m shuttle run, sit-ups and sitting trunk flexion significantly increased. In the exercise group, the TC, LDL-C, and TG significantly decreased. Also, it was noted that the HDL-C was slightly higher in the exercise group than in the control group, but the difference was not statistically significant. The cortisol levels of the exercise group and control group at baseline were similar. However, after the aerobic resistance training circuit program, the exercise group had a significantly higher cortisol level than the control group. Therefore, regular and continuous aerobic resistance training was effective in improving the body composition, blood lipids and health-related fitness.

The purpose of this study was to investigate the effects of maximum and endurance resistance exercises on total work, blood viscosity, and erythrocyte volume ratio. The study subjects were selected as 15 men in their twenties with 12 months or more of resistance exercise experience, and the bench press 1RM was measured before the experiment, and the experiment for each condition was cross-allocated at intervals of one week, and the maximum repetition was performed in 6 sets. As a result, the total amount of exercise showed that the muscular endurance strength was higher than that of the maximum muscular strength (p<.001), and the blood viscosity and erythrocyte volume ratio were higher after exercise than before (p<.01) regardless of the total exercise amount. In summary, it was found that blood viscosity was not affected by exercise intensity and amount of exercise, and increased with one-time resistance exercise. This is clinically significant in constructing a resistance exercise program, and it is considered to be a reference material in creating an exercise program for clinical patients related to vascular disease.

Objective: This study aims to discover how tongue self-resistance exercise affects the swallowing function of patients with stroke. Method: The subjects of this study were two patients who were treated at the Y hospital in Gyeonggido. Data were gathered by VFSS regarding the degree of swallowing disability and oral intake before and after intervention. This study analyzed case studies of two patients. One patient's intervention was applied in September 2012 for three weeks. The other's intervention was applied in February 2014 for three weeks. At the first session, the VFSS examination was administered. Then, intervention began after the patients gave their consent for participation. Each session was practiced 10 times per set, but one session had 3 sets. Intervention frequency consisted of five sessions per week, and it was conducted for three weeks. Tongue self-resistance exercise included tongue protrusion, tongue lateralization, and tongue elevation on the hard palate. Results: The first tongue self-resistance exercise had a positive effect on swallowing function because of the decrease in VFS score. The second tongue self-resistance exercise showed improved oral intake based on FOIS scores. Conclusion: This study's results suggest that there are many benefits of tongue self-resistance exercise on the swallowing function when it is applied to patients with stroke.

The purpose of this study was to investigate the effect of endurance and resistance exercise by using different intensity on diabetic-related blood profiles in impaired glucose tolerance mice. 54 C57BL/6 mice were divided into (1) Control group (CO, n=9), (2) impaired glucose tolerance group (IGT, n=9), (3) IGT + 50% of VO_2max endurance exercise group (IGT50A, n=9), (4) IGT + 75% of VO_2max endurance exercise group (IGT75A, n=9), (5) IGT +50% of 1RM resistance exercise group (IGT50R, n=9), 그리고 (6) IGT + 75% of 1RM resistance exercise group (IGT75R, n=9). Endurance exercise program was performed 40 min/day, 5 days a week for 8 weeks on treadmill. Resistance exercise program was consisted in ladder-climbing 8 set/day, 5 days a week for 8 weeks. After completed the exercise program, there was no different insulin level in the groups. The fasting glucose was significantly lower in CO than in other groups, and it was not different among the exercised groups. However, IGT75R was statistically lower than IGT. HOMA-IR was only different between CO and IGT. HbA1c was higher in IGT than in other groups. As compared with exercised groups, IGT 75A was lower than IGT50R. TC was lower in CO than in other groups, but there was no different in TG. Endurance exercise groups showed higher than CO and IGT in HDL-C level. LDL-C was lower in CO than other groups. In addition, IGT75A was lower than IGT and IGT50R in LDL-C level. In conclusion, 75% of 1RM resistance exercise had more positive effect on fasting glucose, and 75% of VO_2max endurance exercise improved HbA1c and LDL-C level. In addition, endurance exercise had more effective in HDL-C improvement as compared with resistance exercise.

Purpose : The purpose of this study was to demonstrate the effectiveness of combined exercise for 12 weeks on the adiponectin and obesity related variables in overweight and obese children. Methods : Eighteen children in 5th grade in a certain elementary school in Busan were recruited. They were all overweight or obese children(more than 85 percentile in body mass index). Nine children in the experimental group were given exercises consisting of walking and band resistant training for 12 weeks. Auxological data(including height, weight and body fat mass) and laboratory data (fasting blood sugar, insulin, adiponectin) were checked at baseline and at the 1 week, and at the 4 weeks and 12 weeks stages of their exercise program. Insulin resistance and sensitivity were evaluated indirectly using HOMA index and QUICKI index. Results : Adiponectin gradually decreased until the 4 weeks point and gradually increased thereafter to the starting level at the 12 weeks stage. Body weight, body mass index(BMI) and HOMA index significantly decreased more at the 1 week, 4 weeks, and 12 weeks stages in the experimental group than in the control group. Body fat mass significantly decreased at 12 weeks. The change of insulin was significantly correlated with changes of body weight and BMI. But there was no correlation between changes of adiponectin and changes of insulin. Conclusion : Exercise seems to effect the adiponectin concentration. And it might be assumed that exercise increases the adiponectin concentration if it is continued for long time(may be more than 12 weeks). More studies may be necessary to draw that conclusion.
