본 연구의 목적은 골프 숙련도에 따른 아이언 샷 연습량이 혈중 근 손상 지표물질과 피로물질 농도 변화에 미치는 영향을 분석하는데 있었으며, 남자골프선수 24명을 대상으로 초급(8명), 중급(8명), 고급(8명)으로 나누어 각각 다른 연습량(100,200, 300타)으로 연습하는 동안 채혈시기별로 혈중근손상 지표물질인 CK(creatine kinase), LDH(lactate dehydrogenaset-혈중 피로물질인 무기인산, 젖산, 암모니아, 그리고 IGF- I (insulin like growth factor-I)과 크레아티닌의 수준차이를 비교하였다. 그 결과, 운동하는 동안 피로물질과 근손상 지표, 크레아티닌은 숙련도가 높을수록 낮은 수준을 보였으며, 연습량이 증가됨에 따라 높은 수준을 나타내었다. 회복시 피로물질과 크레아티닌은 운동종료 후 빠르게 회복되었으나, 근손상 지표, 특히 CK는 24시간이 지난 후에도 회복되지 못한 결과를 보였다. 따라서, 골프연습도 격렬한 운동과 마찬가지로 근손상과 상해를 예방하기 위해서는 개인의 숙련도와 연습량에 따라 차별화된 훈련과 회복방법을 고려해야 할 것으로 사료된다.

[Purpose] The effect of acute nitrate supplementation on muscle fatigue is largely unknown. This study aimed to evaluate the effect of acute nitrate supplementation on muscle fatigue. [Methods] Thirty-five recreationally active subjects consumed 140 ml of beetroot (BR) juice (nitrate: 8 mmol·d^-1) or placebo (PL) 12 and 2.5 hours before two exercise sessions. Peak torque was measured during 50 repetitions, at maximal effort, and during concentric knee extensions at 90°·s^-1. Blood pressure (BP) was recorded pre- and post-exercise. [Results] Peak torque, maximum work, rate of fatigue, and rate of work fatigue were similar between the BR and PL conditions. Post-exercise diastolic BP (BR: 67.2 ± 9.8 vs. PL: 64.5 ± 7.9 mmHg, p < 0.05) and mean arterial pressure (BR: 91.6 ± 9.3 vs. PL: 88.8 ± 8.2 mmHg, p < 0.05) were higher with BR supplementation. [Conclusion] These findings suggest that the acute intake of BR juice had no effect on knee extensor muscle strength or fatigue but increased BP in a healthy recreationally active population.

The conventional studies of the aging effect on cardio-vascular system are mostly obtained from human experiences and can only provide local information. In this study, the effect of fatigue fracture of arterial wall on the blood pressure was investigated by hemodynamic analysis. The aging process was simulated with three stages. The pulse wave velocity increased with age. The systolic blood pressure increases consistently but diastolic blood pressure decreases with age. The simulated results show in good accordance with the clinical ones.

Purpose: The aim of the study is to measure the quality of cardiopulmonary resuscitation (CPR) and the fatigue of rescuers wearing PPE (Level D) during a CPR session and to ultimately provide suggestions of safety standards for rescuers. Methods: 36 subjects were enrolled in the study. The subjects were divided randomly into three groups of two-members, three-members, and four-members. Each group performed CPR for 30 minutes. Blood lactate concentration, heart rate, rating of perceived exertion, chest compression depth and rate were measured before experiment and after each cycle. Results: There was a difference in the blood lactate concentration during CPR cycle by member of shifts (p=.014). The blood lactate concentration increased during CPR (p=.000). Subjective fatigue was a significant difference of chest compression in cycles 3, 4, and 5 for the member of shifts during CPR (p=.049, p=.009, p=.015). Depth and rate of chest compression were not different for the member of shifts during CPR. Conclusion: It is necessary to establish standards for the member of shifts during CPR, to reduce the fatigue of rescuers.

Purpose: The purpose of this study was to examine the effects of aromatherapy on blood pressure, pulse, fatigue and sleep for patients with allergic rhinitis admitted at a hospital specialized in an oriental medicine. Methods: This research was a single-group pretest-posttest design. Data were collected at admission and discharge from May to December, 2009. The patients selected were received an aroma inhalation therapy via nebulizer with a 2% diluted oil mixture of eucalyptus and peppermint with 10 cc of saline solution in the ratio of 1:1 ones a day for 15 min in the period of 2 weeks. The data were analyzed for the descriptive statistics and paired t-test. Results: There was a statistically significant improvement on physical and psychological symptoms of fatigue and sleep with a increase in systolic blood pressure. Conclusion: Eucalyptus and peppermint blended oil aromatherapy as a sleep induction modality is an effective nursing and therapeutic intervention in conjunction with acupuncture and herbal medicine for symptoms of nasal congestion. However, further well designed research is required in evaluating the effectiveness of the types of clinically available essential oil.

Purpose: The purpose of this study was to examine the effects of hand stimulation intervention by moxa on fatigue and the blood cortisol level in pregnant women. Method: This study was conducted using a nonequivalent control-group pretest-posttest design from Oct 13 to Dec 15, 2005. The participants were pregnant women in the Gyeong-gi area. The numbers of experimental and control subjects were 16 and 13, respectively. The hand stimulation intervention by moxa was applied to the experimental group three times a week, for a total of fifteen times for five weeks. Result: The blood cortisol level was statistically significantly different between the two groups. However, the degree of fatigue was statistically insignificant. Conclusion: These results suggest that hand stimulation intervention by moxa can be used as an effective nursing intervention in pregnant women. The implications for nursing practice and directions for future research are discussed.

Objectives: This study was conducted to evaluate the clinical efficacy of EC102, a composition containing oriental medicine, for relieving VDT syndrome, including eye symptoms and musculo-skeletal symptoms. Methods: The study was conducted by using a double blind randomized controlled trial design. 40 subjects were randomly assigned to the placebo group or the EC102 group. The visual analogous scale (VAS) was used to evaluate various VDT symptoms, including eye pain, eye fatigue, back pain, shoulder pain and so on. Refractory indexes were measured using refractometer, and tear film break-up time (BUT) were measured using fluorescein strip. Blood circulation was measured using photo-plethysmography. Blood pressure and blood biochemistry were also measured. Statistical analysis was conducted by a Mann-Whitney test using SPSS 9.0 software. Results: The EC102 group showed a statistically significant reduction of eye symptoms including eye fatigue, eyelid fatigue, itching, pain, and photophobia when compared with the placebo group (P<0.05). The EC102 group also showed a statistically significant reduction of back pain compared with the placebo group (P<0.05). No side effects on liver function and blood biochemistry were observed. Conclusions: EC102 has significant clinical efficacy for relieving symptoms of VDT syndrome.

The purpose of this study was to analyze the effects of intake of aronia, montmorency, and Prunus mume on 10 km endurance exercise by investigating changes in blood lactate, ammonia, creatine kinase (CK), and lactate dehydrogenase (LDH), and eventually to recommend them as ergogenic aids, which are effective for recovering from exercise fatigue and muscle damage. The subjects were divided into a P. mume intake group, an aronia intake group, a montmorency intake group, and a control group. Blood samples were taken from the brachial vein at rest, and at 0, 30 min, and 24 hr after running to measure recovery status. All data were analyzed by a two-way repeated-measures analysis of variance using SPSS. The results are summarized as follows: The changes in blood ammonia and LDH concentration following 10 km of running were not significantly different among the groups. However, lactate and CK recovery ratio increased significantly in the aronia and montmorency groups compared to those in the P. mume and control groups. In particular, CK concentration was significantly different in the montmorency group compared to that in the other groups. These results suggest that the effects of aronia and montmorency are associated with improved recovery from muscle fatigue and damage induced by highly intensive exercise, endurance exercise, or overtraining. In particular, montmorency is recommended as an ergogenic aid to inhibit muscle pain resulting from high-intensity endurance exercise.
