Food-dependent exercise-induced anaphylaxis (FDEIAn) is induced by different types and various intensities of physical activity, and is distinct from food allergies. It has been shown that consumption of allergenic food followed by exercise causes FDEIAn symptoms. Intake of allergenic food or medication before exercise is a major predisposing factor for FDEIAn. Urticaria and severe allergic reactions are general symptoms of FDEIAn. Dermatological tests and serum IgE assays are the typical prescreening methods, and have been used for several decades. However, these screening tests are not sufficient for detecting or preventing FDEIAn. It has been found that exercise may stimulate the release of mediators from IgE-dependent mast cells that can result in FDEIAn when a certain threshold level has been exceeded. Mast cell degradation might be a major factor to induce FDEIAn but this has not been determined. A number of foods have been reported to be involved in the onset of FDEIAn including wheat, eggs, chicken, shrimp, shellfish, nuts, fruits, and vegetables. It is also known that aspirin increases the occurrence of type I allergy symptoms when combined with specific foods. Moreover, high intensity and frequent exercise are more likely to provoke an attack than low intensity and less frequent exercise. In this paper, we present the current views of the pathophysiological mechanisms underlying FDEIAn within the context of exercise immunology. We also present a detailed FDEIAn definition along with etiologic factors and medical treatment for cholinergic urticaria (UC) and exercise-induced anaphylaxis (EIA).

Purpose: This study was to evaluate the effects of a physical activity reinforcement program on exercise compliance, depression, and anxiety in continuous ambulatory peritoneal dialysis(CAPD) patients. Method: A nonequivalent control group with a pre-post test was designed. Data collection was done from December, 2002 to June, 2003 at a hoapital. The degree of depression and anxiety of the patients was assessed by the score of SCL-90-R, and exercise compliance was measured by exercise period, frequency, time and intensity. The experimental group was composed of 19 participants who were educated based on an exercise education protocol and carried out walking exercises two to four times a week after hearing verbal persuasion biweekly through the telephone or a face-to-face interview for 12 weeks, while 17 participants in control group received no intervention. Result: 1. The experimental group showed significant improvement in self-efficacy of exercise compliance (U=79.00, p=.01), exercise period ($x^2$=20.84, p=.00), exercise frequency ($x^2$=9.03, p=.0l), exercise time ($x^2$=9.03, p=.0l) and exercise intensity ($x^2$=11.09, p=.00) compared to those of the control group. 2. The experimental group showed a lower depression score (U=84.50, p=.01) than the results of the control group. 3. However, there were no changes in anxiety level compared to the control group. Conclusion: The physical activity reinforcement program was found to have an effect on exercise compliance and the depression score of CAPD patients. The results provided evidence for the importance of physical activity and verbal persuasion in CAPD patients.

Sling exercise treatment(S-E-T) is a therapeutic exercise based on scientific studies for the purpose of treating musculoskeletal or neurological disorders thereby improving strength, endurance, and skills for sensory-motor integration. Exercise resistance and intensity can be modified in various ways by changing the length of rope, patient position, therapist's manual resistance, and using elastic rope. The therapist can also progress to successively higher levels of exercise resistance and intensity by changing the position of the hanging point: the subject of this article. In brief, there are three axial components in S-E-T; hanging point, motor axis, and suspension point. The hanging point can be changed in several ways in relation to the joint; axial, superior, inferior, medial, and posterior hanging points. The position of the hanging point affects the amount of load on agonist and antagonist muscles as well as on the range of motion. To create an advanced exercise program, selection of hanging point can be two-dimensional such as superior-lateral or anterior-medial. Therapists, therefore, can freely but carefully select the best hanging point based on the purpose of the exercise and their level of knowledge in S-E-T.

The purpose of this study is to investigate the changes in the number of repetitions and the repetition rate according to the exercise mode when performing 65%1RM resistance exercise at the 1-minute rest interval and the 3-minute rest interval. Sixteen healthy male subjects were treated with Bench press and Biceps curl of 65%1RM intensity at 1 and 3 minute rest intervals. The number of repetitions for each set of 1 minute rest interval showed a significant decrease from 1set to 5set in bench press. biceps curl showed a significant decrease from 1set to 4set. The repetition rate according to the exercise mode with a 1-minute rest interval showed a significant difference from 2sets to 4sets. In the repetition rate for each set, bench press showed a significant decrease from 1set to 5set. biceps curl showed a significant decrease from set 1 to set 4. The number of repetitions according to the exercise mode with a 3-minute rest interval showed a significant difference from 2sets to 5sets. In the number of repetitions for each set, bench press showed a significant decrease from 1set to 5set. biceps curl showed a significant decrease from 1set to 4set. The repetition rate according to the exercise mode with a 3-minute rest interval showed a significant difference from 2sets to 5sets. In the repetition rate for each set, bench press showed a significant decrease from 1 set to 5 sets. biceps curl showed a significant decrease from 1set to 4set. In summary, the decrease in the number of repetitions according to the set progression in the resistance exercise of the endurance depends on the exercise mode, and the increase of the rest interval or the decrease of the weight-intensity should be considered when aiming for more exercise.

Purpose: The purpose of this case study was to investigate three poor fibrinolytic responders with chronic ischemic stroke to acute exercise intensity and time. Methods: Three ischemic stroke patients (male) from the stroke center located at Busan metropolitan area in Republic of Korea volunteered at this study. They performed two single session exercises that were a VO2peak test and a single bout treadmill walking (70-75%HRpeak, 30 min, 50min). Fasting blood samples for determination of tissue Plasminogen Activator (tPA) and Plasminogen Activator Inhibitor-1 (PAI-1) were obtained before, immediately after, 30min after acute exercise. SPSS 12.0 was used for analyzing of data and computing mean and standard deviation, and change rate was conducted between times. Results: In fibrinolytic activity according to the intensity and time of acute exercise, tPA change increased steadily during the recovery stage after the VO2peak in the cases, but PAI-1 activity showed different patterns among the cases. In a single bout treadmill walking (70-75%HRpeak, 30 min, 50min), tPA change increased between 30min and 50min. Conclusion: In conclusion, these results suggest that the exercise prescription for poor fibrinolytic responder with three male chronic ischemic stroke patients without motor disability recommend at 70-75%HRpeak, over 30min.

Objectives : The effects of exercise on bone density have been found to be inconsistent in previous studies. We conducted a cross-sectional study in premenarcheal girls to test two hypotheses to explain these inconsistencies. Firstly,'the intensity of mechanical strain, in terms of the ground reaction force(GRF), has more important effects on the bone mass at a weight-bearing site', and secondly, 'calcium intake modifies the bone response to exercise'. Methods : The areal bone mineral density was measured at the Os calcis, using peripheral dual energy X-ray absorptiometry, in 91 premenarcheal girls aged between 9 and 12 years. The intensity of mechanical strain of exercise was assessed by a self-report questionnaire and scored by the GRF as multiples of body weight, irrespective of the frequency and duration of exercise. The energy and calcium intake were calculated from the 24-hour dietary recall. An analysis of covariance(ANCOVA) was used to determine the interaction and main effects of exercise and calcium on the bone density, after adjusting for age, weight, height and energy intake. Results : The difference in the bone density between moderate and low impact exercise was more pronounced in the high than low calcium intake group. The bone density for moderate impact exercise and high calcium intake was significantly higher than that for low impact exercise (p=0.046) and low calcium intake, after adjusting for age, weight, height and energy intake. Conclusions : Our study suggests that the bone density at a weight-bearing site is positively related to the intensity of mechanical loading exercise, and the calcium intake may modify the bone response to exercise at the loaded site in premenarcheal girls.

본 연구의 목적은 청소년기에서 성인기에 해당하는 암컷 생쥐를 대상으로 유산소 운동과 유산균 섭취가 운동 학습능력과 체중에 미치는 영향을 파악하는 것이다. 실험대상을 비운동, 중강도, 고강도 운동과 유산균 섭취, 비섭취 변인의 6집단으로 나누고 4주간 운동강도별 트레드밀과 유산균으로 처치하였다. 처치 전 후로 버티컬그리드 테스트를 수행하여 운동학습능력과 체중을 평가하였다. 버티컬그리드 테스트에서는 유산균을 섭취하고, 고강도 운동을 수행한 집단의 상행·회전·하행 속도가 가장 빨랐으며 운동을 하지 않은 비유산균집단과 유의한 차이를 보였다(p<.001). 운동을 하지 않은 비유산균집단이 가장 느린 수행 속도를 기록했다. 또한, 운동 수행과 유산균 섭취를 함께한 집단이 운동만 수행한 집단에 비해 빠른 수행 속도를 기록하는 경향을 보였다. 체중 변화를 비교한 결과 중강도 운동만 수행한 집단의 체중 증가는 운동을 수행하지 않은 비유산균집단의 체중 증가에 비해 유의하게 높았다(p=.032). 종합하면, 성장기의 유산소 운동은 운동학습 향상에 도움을 줄 수 있으며, 유산균 섭취와 병행하면 보다 효율적인 운동학습이 이루어질 수 있다.

목적 : 수면장애는 노인에게 있어 다양한 이유로 빈발하고 있다. 이러한 노인의 수면장애에서 운동 강도에 따른 지속적인 운동습관이 수면장애의 치료적 효과를 줄 수 있는지를 밝히기 위해서 뇌파와 멜라토닌의 농도를 이용한 과학적인 방법으로 접근하는 것이 본 연구의 목적이다. 연구방법 : 일부지역의 노인시설에 거주하는 65세 이상의 노인 30명을 대상으로 하였다. 수면장애의 판단은 수면시간 6시간 이하의 경우(Kozier et al, 2004)와 PSQI(Pittsburgh Sleep Quality Index)의 점수를 동시에 만족하는 경우로 정하였다. 운동유형별 적용은 저강도의 걷기운동, 중강도의 유산소 운동, 고강도의 저항성 근력운동을 적용하였으며 측정도구는 뇌파에서 파형을 체크하기 위하여 QEEG 8-System(LAXTHA Inc. KOREA) 기기와 수면의 질을 검사하기 위해서 수면다원검사에 사용하는 Polysomnograpy (Compumedics, Australia) 기기를 사용하였다. 그리고 TTC(triphenyltetrazolium chloride) 염색과 H & E(Hematoxylin & Eosin) 염색을 통해 조직학적 양상을 관찰하였다. 결과 : 중강도의 유산소 운동 후에 멜라토닌의 농도와 뇌파로 측정한 수면지수에는 긍정적인 유의미한 변화가 있었다. 중강도의 유산소 운동에서는 SWS가 저강도, 고강도 운동보다 유의한 효과가 있었고 SWS의 관찰지표인 델타파의 유의한 변화가 있었다. 결론 : 인체의 일주기성 리듬의 생화학적, 행동학적 기능에 변화를 가져오는 노인에게서 수면장애에 대한 지속적인 운동은 운동의 유형에 따라 효과가 다름을 알 수 있었고 특히 유산소 운동이 다른 운동보다 노인 수면장애에 효과가 크다는 것을 멜라토닌의 농도와 뇌파를 통하여 알 수 있었다. 노인에게 맞춤형 운동을 제공하여 노인들의 삶의 질에 유용하고 건강한 말년을 제공할 수 있을 것이다.
