The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. This research was planned to apply Artesmisia capillaris, which is one of the most widely used oriental medicinal resource into beverages, and to evaluate the validity and the nutrients of the developed beverage with Artemisia capillaris. Following this plan, we analyzed contents of the general nutritional composition, mineral and amino acid contents. And to evaluate the improvement of blood circulation and the ability to recover from fatigue, we had a group of athletes to regularly take the beverage before and after exercise and checked the heart rates, and blood components before exercise and after exercise. Brix, pH and titratable acidity of develoued drink were 9.2%, 4.4 and 0.04%, respectively. The approximate nutritional composition of beverage was carbohydrate, 2.70%, crude protein, 6.00%, crude ash, 0.20%, and crude fat, 0.10%. And developed beverage contained essential amono acids and minerals (p, Ca, K, Na, Fe, Mn, Zn). Heart rates, lactic acid, glucose, creatinine, LDH, GOT, GPT and lipid concentratios in blood were decreased after taking the beverage with Artemisia capillaris for 6 weeks, both in stable condition and after exercise. Since the athletes who participated In our research were doing aerobic exercise regularly, we judged that this result was formed not only by aerobic exercise, but also by the function of developed beverage with Artemisia capillaris the athletes took for 6 weeks. We believe that taking the beverage regularly will help the improvement of the public health and the athleticism of the athletes. We hope that this result will be used as the basic resource in developing of the beverage with Artemisia capillaris in the near future.

The hot water extract of leather carp (Cyprinus carpio nudus) has been used as a nourishing tonic soup and as an aid for recovery from physical fatigue. In this study, we investigated the effect of leather carp extract on exercise performance in mice. Swimming endurance and forelimb grip strength were assessed following oral administration of the extract (once per day for 7 days) at a dose of $0.5 mg/10{\mu}L/g$ body weight. After 7 days, mice given the leather carp extract had significantly greater swimming endurance [$105{\pm}18s$ (P<0.05); 52% longer than day 0] and forelimb grip strength [$1.18{\pm}0.05$ Newton (P<0.01); 17% greater than day 0]. The extract increased muscle mass, but had little effect on body weight. Following the swimming exercise, blood glucose, glutathione peroxidase, and superoxide dismutase levels in extract-fed mice were significantly higher (145%, 131%, and 106%, respectively) than in the saline control group. Blood levels of high-density lipoprotein cholesterol were also significantly increased (128%) in mice given the extract compared to the controls. These results suggest that leather carp extract can improve physical exercise performance and prevent oxidative stress caused by exhaustive workouts.

Objectives: This Study was designed to investigate the effect of Oxygen chamber to recover muscle fatigue. Methods: Twenty Subjects were divided into Oxygen Chamber Group (n=10) and Rest group (n=10). Subjects visited hospital two times, blood tests were performed 3 times for each visit. 1st blood test was performed in 4 hours hunger state. 2nd blood test was performed within 5 minutes after the 6 minutes bike exercise. 3rd blood test was performed after the 40 minutes Oxygen treatment or 40 minutes rest in bed. Blood test items were Lactate, Glucose, Lactate Dehydrogenase, Creatine Kinase, Free Fatty Acid. 2nd visit was applied 1st visit process, But Oxygen Chamber group was crossed over to Rest Group, Rest Group was crossed over to Oxygen Chamber group. The Blood test result was analyzed with paired T-test using SPSS for Windows version 21. Results: The reduction of Lactate in Oxygen Chamber Group (6.86±2.07 mmol/ℓ) was higher than Rest group (6.57±2.33 mmol/ℓ), but it was not statically significant (p=0.68). The reduction of Glucose in Oxygen Chamber Group (6.85±12.14 mg/dl) was lower than Rest group (7.60±9.83 mg/dl), but it was not statically significant (p=0.83). The reduction of Lactate Dehydrogenase in Oxygen Chamber Group (16.10±14.91 mmol/ℓ) was lower than Rest group (19.75±12.46 mg/dl), but it was not statically significant (p=0.41). The reduction of Creatine Kinase in Oxygen Chamber Group (13.40±5.69 U/ℓ) was lower than Rest group (15.25±8.01 U/ℓ), but it was not statically significant (p=0.41). The reduction of Free Fatty Acid in Oxygen Chamber Group (285.50±174.13 uEq/ℓ) was higher than Rest group (196.15±131.58 uEq/ℓ), but it was not statically significant (p=0.07). Conclusions: This study showed Oxygen chamber therapy could be effective to recover muscle fatigue.

The purpose of this study was to examine the effect of D-ribose supplementation on the changes of blood fatigue substances (lactate, ammonia, phosphate and hypoxanthine) after maximal exercise performance in college male students. The experimental trials of each subject were divided into the following conditions: placebo supplement trial and D-ribose supplement trial. The subjects exercised using a Concept II Indoor rowing ergometer for 2,000 m Single Skull event. The subjects ingested 200 mg/kg of D-ribose after breakfast, lunch, dinner, as well as thirty minutes before exercising, for six days. Blood fatigue substances were continuously measured before exercise, immediately after exercise, and thirty minutes after exercise. The results indicated a significant difference in blood phosphate and hypoxanthine levels between the two experimental trials in the 30 minute recovery period (p<0.05). However, there were no significant differences in blood lactate and phosphate levels between the two experimental trials. The results of our study suggest that D-ribose supplementation during maximal rowing exercise for 7~8 minutes may contribute to the improvement of metabolic responses as a beneficial ergogenic aid accelerating fatigue clearance.

While the survival rate of preterm infants and employment rates of mothers with infants have been dramatically increasing, little is known about the impact of maternal employment and having premature infants on maternal health recovery after delivery. The purpose of this longitudinal study was to examine differences in postpartum health by mother's employment and infant's prematurity over time during the first 3 months postpartum. The study used a longitudinal design and was secondary data analysis from a large study. A convenience sample of 132 mothers was recruited with mothers who had fullterm or preterm infants through the postpartum unit. They were followed up for 3 times (at 1-2 days, 6 weeks, and 3 months) during the first 3 months postpartum period. Level of fatigue and hysical symptoms were indicators for postpartum physical health; Positive affect and negative affect were assessed for postpartum mental health, and role functional status after childbirth was for role performance. Finding indicated that health indicators changed significantly over time but there was no main or interaction effect for maternal employment status. There were main effects of infant's prematurity on positive affect, negative affect, and role functional status (self-care and social and community activities). This study enhanced the understanding of postpartum health of mothers with preterm infants as well as those with fullterm infants during the postpartum period.

To investigate the status of farmers health management for health promotion, and for checking the effect of village health care center during 1 year, 746 subjects were selected with cluster method in 8 provinces of Korea. The most frequent group was 40th of age (39%) : elementary school graduates (32%) The self-conscious of health status tested with CMI (Cornell Medical Index) questionnaire, the subjects in the village of health care center had lower health status than those of conventional village. The farmers living in the village with health care center had longer agricultural work (p＜0.05) and more frequency of spraying pesticides in the fields. The subjects of living the village of health care center were frequently exercise (34%) with health appliance use methods (30%), but the duration time of exercise was similar, Dietary habits and agricultural work condition were similar between two groups. For the fatigue recovery, steeping and bathing were most favorite methods, but exercise was lowest. It was significantly different between 2 groups the fatigue recovering methods, the subjects of village with health care center were more doing exercise (p＜0.01), less sleeping (p＜0.01) than those of conventional village. The working condition of self-estimated of farmers was not good, only 8.7% was thought pleasant condition. Of the various health factors, exercise, nutrition, and working situation would be more important. Considering on farmers exercise, it was very weak point for health management. The foundation and leading of the Farmers health care center was encouraged to farmers. For more effective operations, the experts education, easy and funny exercise program, and health promotion committee for administrators would be needed. The better systemic and continuous exercise programs should develop for associating livelihood. Funding for this project provided by the ministry of health and welfare of Korea.

This study investigates the effect of wrist guards equipped with electronic muscle stimulation on reducing wrist pain and improving wrist function of actual lure fishing participants. This study combined conductive fabrics by selecting two products of wrist guards that can be used in lure fishing, which requires holding fishing rods with hands for a long time. It was conducted on ten healthy men aged 35 to 45, and the selection conditions were selected for those who did not have a history of surgery on the wrist and are currently enjoying lure fishing as a hobby. The experimental movement was performed 100 times before each experiment to cause delayed muscle pain to cause wrist fatigue when lure fishing was performed with the operation of grip strength and range of motion. As a result of this study, it was found that pain reduction, range of motion, and grip strength were improved when electrical stimulation was applied after wearing a wrist band in the form of a wrist wrap and semi-gloves. The conclusion of this study was that when electrical stimulation was applied to the wrist guards, the effect of improving the fatigue and function of the wrist could be confirmed through experiments. Through this study, it is expected that wearing electronic muscle stimulation wrist guards will have a significant effect on preventing wrist injuries and improving functional recovery for lure fishing participants.

OBJECTIVES : Schizandra chinensis is well known for its efficacy at liver function reinforcement, relieving thirst and recovery from fatigue. In this study, we examined the effects of sports drink containing Schizandra chinensis on serum metabolic substrate, electrolyte, stress indicators, related-enzyme and exercise performance, rectal temperature, and heat shock proteinb70 (HSP70). METHODS : Elite long-distance runners (male, 21.3yrs, n=16) were selected and divided into two groups; an experimental group (EXP, n=8) and a control group (CON, n=8). A beverage containing Schizandra chinensis was supplemented 3 times per day to EXP for 4 weeks. Serum biochemical elements (glucose, lactate, total cholesterol, triglyceride, high density lipoprotein cholesterol, glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, creatinine, creatine phosphokinase, lactate dehydrogenase, blood urea nitrogen, Na, K, Cl) were analyzed by auto blood analyzer. Exercise performance was measured by treadmill exercise test, HSP70 was detected by electrophoresis and Western blotting, and rectal temperature was measured by rectal temperature probe. RESULTS : Administration of the beverage increased significantly the rest level of blood Na, Cl and glucose and decreased significantly lactate dehydrogenase, glutamate oxaloacetate transaminase. No difference was found in exercise performance, rectal temperature increment or HSP70 concentration between groups. CONCLUSIONS : Administration of a sports drink containing Schizandra chinensis altered blood glucose, lactate dehydrogenase, glutamate oxaloacetate transaminase, Na and Cl levels.

This is a study of two admissional patients whose chief compiaints were yellow color and itching, and fatigue. Diagnosis and treatment was based on overall analysis of symptoms from the point of view of Jaudice due to damp-geat from an Oriental Medical point of view. Injinolyungsangami was administered against Jaudice due to damp-heat and showed desirable effect on more rapid recovery of total bilirubin than previous reports about treating jaudice. Improvement was observed. For lack of objective criteria to evaluate improvement of these symptoms more case studies of this kind, done with screening tests and proper treatment through clinical application of the thinking of Oriental Medicine, will be needed.
