The effect of exercise and/or high fat diet on carnitine status and carnitine palmitoyltransferase I(CPT I) level were investigated in Weanling Sprague Dawley rats. The rats were fed an AIN 76 diet or a modified high fat AIN diet, supplemented with 35% corn oil, for 31 days. During the 31 day period half of the animals in each dietary group were exercised on a treadmill for 90 minutes per day. Carnitine concentrations were determined in plasma and liver and CPT I mRNA levels were measured by Northern blot analysis with CPT I cDNA probe in livers of rats. Exercise rats gained less weight than non exercised rats during the study for high fat diet group. Exercise rats had a higher plasma acid soluble acylcarnitine and acid insoluble acylcarnitine concnetrations than non exercised rats for normal diet group. Exercise or high fat diet increased liver carnitine concentration, but a mixed effect was not shown. In exercised rats, CPT I mRNA levels increased significantly relative to those of nonexercised rats. CPT I mRNA levels also increased when compared high fat fed rats with those of normal diet fed rats. These data suggest that there is a correlation between carnitine concen trations and CPT I mRNA levels and that CPT I can be regulated at the transcriptional level by exercise and/or high fat diet.

Purpose: This study was conducted to examine the effects of walking exercise training on body composition and physical fitness in middle aged women. Method: The subjects were randomly assigned into an obese walking exercise training group (n=21), a non-obese walking exercise training group (n=9), or a control group (n=10). The women in the treatment groups were then subjected to brisk walking at 50~70% of maximum heart rate twice a week for 12 weeks. The results were then analyzed by repeated measures ANOVA using SPSS 12.0 for windows. Results: Body weight, BMI, % body fat, and WC were not significantly improved in the obese walking exercise training group and the non-obese walking exercise training group. However, muscular flexibility and muscular endurance were significantly improved in each of these groups (p<.05). Conclusion: These results indicate that 12 weeks of walking exercise training enhanced physical fitness. However, the treatment in this study did not improve the body composition of middle aged women.

The purpose of this study was to compare the anthropometry, the serum lipid levels and the nutrient intakes of two groups according to their alcohol intake, smoking habits, regular exercise patterns, menopause status and obesity levels. The subjects consisted of 180 clinically normal adults (males 89, females 91) in the Youngdong area. There were significant differences in the triglyceride (TG) concentrations between the alcohol consumers (169.3 \pm 130.0 mg/dl) and the non-alcohol consumers (111.4 \pm 64.5 mg/dl), and the smokers (165.0 \pm 103.6 mg/dl) and the non-smokers (110.8 \pm 39.0 mg/dl). Although regular exercise did not affect the serum lipid levels, the dietary intakes of cholesterol, niacin and phosphate were significantly higher (p<0.05) in the male exercising group than in the male non-exercising group, and female exercising group consumed more polyunsaturated fatty acids (p<0.05) than the female non-exercising group. The waist/hip ratio. serum total cholesterol (198.4 \pm 36.3 mg/dl) and serum LDL-cholesterol (119.5 \pm 34.9 mg/dl) levels of the postmenopausal females were significantly higher than those of the premenopausal females (p<0.01). The obese males showed higher serum cholesterol, LDL-cholesterol, LDL/HDL, and relative cholesterol levels than those of the normal-weight males : and the obese females showed higher serum TG levels than that of the normal-weight females (p<0.01). These results suggested that drinking, smoking, menopause and obesity are risk factors for hyperlipidemia. Thus, moderation in alcohol consumption, non-smoking, regular exercise and the maintenance of normal weight are necessary to Prevent hyperlipidemia in middle-aged People.

Background: This study was carried out to determine whether non-face-to-face physical therapy would have similar exercise effects to face-to-face physical therapy. Hence, we developed an approach for patients, unable to visit hospitals due to circumstances such as the COVID-19 pandemic, to conduct physical therapy comfortably at home. Objects: This study aimed to compare the effects of a face-to-face and a non-face-to-face physical therapy treatment on improving a rounded shoulder posture. Methods: The participants with rounded shoulders were randomly divided into a face-toface group (n = 15) and a non-face-to-face group (n = 15), and each group performed exercises for four weeks. The exercise program consisted of the bare hands exercise, Thera-Band exercise, and foam roller exercise. The participants in the face-to-face group came to a designated place to perform their exercises, and those in the non-face-to-face group performed the exercises at their own home using Google Meet (Google). Acromial height, total scapular distance (TSD), shoulder pain and dysfunction index (SPADI), and pectoralis minor thickness were measured. Data analysis was performed using the R Statistical Software (R Core Team), and a normality test was performed using the Shapiro-Wilk test. Results: There were no significant differences between the face-to-face and the non-face-toface groups (p > 0.05). When comparing the differences before and after the exercises, both the face-to-face and the non-face-to-face groups showed significant differences in acromial height, SPADI, and pectoralis minor thickness (p < 0.05), and both groups showed no significant difference in TSD before and after the exercises (p > 0.05). Conclusion: The results of this study support the results of previous studies reporting that shoulder stabilization exercise and pectoralis minor stretching training improves round shoulders. In addition, this study revealed that both the face-to-face and the non-face-to-face physical therapy treatments had therapeutic effects.

The purpose of this study was to know the effect of shourt termed fasting on the usage of metabolic energy sources and the metabolic differences between non-athletic and athletic subjects. Subjects were divided into non-athletic and athletic group and exercise was loaded on both groups after feeding and fasting. Exercise was loaded by a treadmill running at the speed of 8km/hour for 30 minutes in both groups. The experiment yielded following results. In the fed state, the level of plasma FFA increased markedly after 15 and 30 minutes of exercise compared with it's level of pre-exercise period in both groups. In the fasted state, the level of plasma FFA in non-athletic group increased steadily according to the duration of exercise, while it's level in athletic group showed no changes. At pre-exercise period, the level of plasma FFA was higher in fasted state than fed state. Immediately before the exercise and 15 and 30 minutes after the exercise, blood for the determination of plasma free fatty acid(FFA), glucose, triglyceride(TG)and cholesterol was sampled from antecubital vein, and simultaneously heart rate was measured. In the fed state, the level of plasma glucose was increased mildly according to exercise, and in the fasted state it's level increased according to exercise in both groups also. In the fasted state, the level of plasma TG was lower than that in the fed state. The level of plasma TG and cholesterol in the fed state was no changed by the exercise from the pre-exercise period. The level of plasma cholesterol in athletic group had tendency to lower than that in non-athletic group. Heart rate increased markedly according to exercise in both groups, but the athletic group's increasing rate of heart rate was lower than the non-athletic group's heart rate increased according to exercise and athletic groups heart rate increased early period of exercise, but did not change during lates post-period of exercise.
