Purpose: To examine the effects of power walking exercise on fatigue and overweight in college students with Taeumin constitution. Methods: According to results of the constitution diagnosis (QSCC II), 58 students who were identified as Taeumin, whose BMI was over 23 were assigned to one of three groups. The power walking group walked fast at a speed of 7,000 steps per hour using a pedometer, and the walking group walked at a speed of 5,000 steps per hour. There was no treatment with control group. Each group's fatigue level, blood lipids and body composition before and after the experiment were compared and analyzed. Results: Total fatigue and total cholesterol decreased significantly in the power walking group compared to the walking group and the control group. Weight decreased significantly in the power walking group compared to the control group, and percentage of body fat decreased significantly in both the power walking group and the walking group compared to the control group. Conclusion: When power walking exercise was used with overweight Taeumin students, fatigue, blood lipid, weight and percentage of body fat decreased significantly.

Purpose: The purpose of this study was to estimate the effects of a video low intensity exercise program provided during hemodialysis on fatigue, activity of daily living, positive psychological capital and blood pressure of patients being treated. Methods: A non-equivalent control group pre-post test design was used. Participants were 85 hemodialysis patients assigned to either the experimental group (n=41) or the control group (n=44). The experimental group exercised for about 25 minutes 3 times a week for 8 weeks. Data analyses involved descriptive statistics, $x^2$ test, t-test, multiple regression and repeated measure ANOVA using SPSS/WIN 23.0. Results: The exercise intervention significantly reduced post hemodialysis fatigue and significantly increased positive psychological capital. There was a significant interaction effect on time by group in blood pressure. Systolic blood pressure changes in the experimental group were stable but, changes in the control group tended to increase gradually. Conclusion: To reduce fatigue and increase positive psychological capital for hemodialysis patients, providing exercise during hemodialysis is recommended. Furthermore individualized exercise in terms of intensity, time, duration, etc should be developed and tested. Also, to reduce drastic blood pressure changes during hemodialysis, exercise should be provided.

PURPOSE: This study examined the effects of lowintensity resistance exercise combined with blood flow restriction on muscle activity and muscle fatigue to determine if such a combination may be an alternative to high-intensity resistance exercise in maintaining the muscle mass and strength and preventing degenerative loss of skeletal muscle and to provide basic data for presenting the effectiveness of exercise. METHODS: The interventions were provided for five weeks, four sessions a week, once a day, 60 minutes a session to Experimental group I (n = 13), in which low-intensity resistance exercise was applied by combining blood flow restriction with the biceps curl and experimental group II (n = 12), in which only high-intensity resistance exercise was applied. As a pre-test, the biceps brachii muscle activity and fatigue were measured by surface electromyography, and the hemodynamic variables, such as blood pressure and heart rate, were measured. The post-test was performed identically to the pre-test and compared and analyzed with the pre-test. RESULTS: A significant difference within-group was observed in the biceps brachii muscle activity and fatigue in experimental group I and only in biceps brachii activity in experimental group II. No significant differences were observed between the two groups. CONCLUSION: Since the low-intensity resistance exercise combined with blood flow restriction has similar effects to high-intensity resistance exercise, it is considered an alternative for improving muscle function in groups unable to perform high-intensity resistance exercise.

Objectives : This study was performed to investigate the antifatigue effect of SM-2000 on fatigued and stressed people. Methods : This study was carried out on 23 healthy people who have fatigue and stress. 11 people as the mentally-stressed group were examined by subjective symptoms of fatigue and blood cortisol test. They drank SM-2000 for seven days. SM-2000 was made up herbs which were used for fatigue. After that they were again examined by subjective symptoms of fatigue and blood cortisol test. 12 people as the physically-fatigued group were examined with fatigue biomarkers and exercise test. They also drank SM-2000 for seven days. After that they were again examined with fatigue biomarkers and exercise test. Results : Cortisol level, subjective symptoms of fatigue scores and physical, mental, and neuro-sensory symptoms of fatigue scores after drinking SM-2000 were not significantly increased compared with before drinking SM-2000 in the mental stressed group. SM-2000 significantly decreased lactate, glucose, and phosphorous levels, and running time after drinking SM-2000 was significantly suppressed compared with before drinking SM-2000 in the physically-fatigued group. Conclusions : On the basis of these results, SM-2000 had a clinical antifatigue effect in physically-fatigued people.

The purpose of this study was to analyse the EMG activity of selected muscles with balance taping treatment and blood fatigue makers which accumulated during exercise of progressive maximal intensity. Ten male college students who did not experience any cardiovascular and musculo-skeletal disease were participated in this study. Balance taping were applied to rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinous, semimembranous, and around knee joint. Isokinetic knee joint flexion/extension force, EMG activity, lactate and ammonia as blood fatigue makers during progressive maximal intensity exercise were measured for with/without applying balance taping. The results indicated that although flexion force of total work at $60^{\circ}/sec$ with taping was increased applied taping did not affect to the aerobic exercise ability parameters. Lactate level as blood fatigue makers during progressive maximal intensity exercise after taping was decreased but the ammonia level did not change with same treatment. In isokinetic knee joint test at the angular velocity of $60^{\circ}/sec$, $180^{\circ}/sec$, and $240^{\circ}/sec$ the taping treatment did not affect to any selected muscle EMG activities except maximal EMG of vastus lateralis at $240^{\circ}/sec$.

Manufacturing workers face increased fatigue and stress due to environmental factors in workplace such as noise and vibration. Addressing this issue requires creating conducive rest spaces; however, the existing conditions of rest spaces in manufacturing workplace are subpar and lack sufficient scholarly evidence. This study investigated the effect of nature-based rest spaces on the physical and emotional recovery from fatigue on manufacturing workers. Three manufacturing complexes with nature-friendly rest spaces were selected, and 63 manufacturing workers participated in the study. The measurement tools included the Multidimensional Fatigue Scale (MFS) for fatigue levels, physiological indicators (blood pressure and heart rate), and emotional indicators (Zuckerman Inventory of Personal Reaction Scale; ZIPERS, Perceived Restorativeness Scale; PRS, Profile of Mood States; POMS and State-Trait Anxiety Inventory; STAI). The study compared recovery levels during a 7-minute rest between a space without plants and a space with natural elements. The results indicated a significant reduction in systolic and diastolic blood pressure of participants in green rest spaces compared with those in conventional rest spaces. Regarding fatigue levels, green rest spaces showed a decrease in systolic blood pressure in the middle-fatigue and high-fatigue groups. Positive feelings increased in green spaces, whereas negative emotions decreased, suggesting that short breaks in nature-friendly environments effectively promote workers' physical and emotional recovery. Furthermore, this study emphasizes the importance of green space in various work environments to promote well-being in workers.

Purpose: In this single repeated measures study, an examination was done on the effects of dialysate flow rate on dialysis adequacy and fatigue in patients receiving hemodialysis. Methods: This study was a prospective single center study in which repeated measures analysis of variance were used to compare Kt/V urea (Kt/V) and urea reduction ratio (URR) as dialysis adequacy measures and level of fatigue at different dialysate flow rates: twice as fast as the participant's own blood flow, 500 mL/min, and 700 mL/min. Thirty-seven hemodialysis patients received all three dialysate flow rates using counterbalancing. Results: The Kt/V ($M{\pm}SD$) was $1.40{\pm}0.25$ at twice the blood flow rate, $1.41{\pm}0.23$ at 500 mL/min, and $1.46{\pm}0.24$ at 700 mL/min. The URR ($M{\pm}SD$) was $68.20{\pm}5.90$ at twice the blood flow rate, $68.67{\pm}5.22$ at 500 mL/min, and $70.11{\pm}5.13$ at 700 mL/min. When dialysate flow rate was increased from twice the blood flow rate to 700 mL/min and from 500 mL/min to 700 mL/ min, Kt/V and URR showed relative gains. There was no difference in fatigue according to dialysate flow rate. Conclusion: Increasing the dialy-sate flow rate to 700 mL/min is associated with a significant increase in dialysis adequacy. Hemodialysis with a dialysate flow rate of 700 mL/min should be considered in selected patients not achieving adequacy despite extended treatment times and optimized blood flow rate.
