본 연구의 목적은 근대 5종 선수(Pentathlon athletes)들을 대상으로 glutamine 섭취여부가 최대하 강도의 지속적 운동 후 혈중 glutamine, ammonia, lactate acid 및 CK의 변화에 미치는 효과를 확인하는 것이다. 연구 대상의 경우 근대 5종 남성 선수 14명을 무작위 선출하여 glutamine 처치그룹(Glu-G), 무처치(Con-G) 그룹으로 분류한 후 O2max의 75%강도로 트레드밀 운동을 90분간 실시하였으며, Glu-G의 경우 glutamine을 하루 100mg․kg-1, 7일간 투여하여 다음과 같은 결론을 얻었다. 첫째, Glu-G은 트레드밀 운동을 실시한 후 Con-G에 비하여 혈중 glutamine의 수준이 유의하게 높게 나타났다. 사전 glutamine 을 섭취하기 전 그룹 간 혈중 glutamine 의 농도에는 유의한 차이가 나타나지 않았으나, 7일 간 glutamine 섭취 후 동일한 검사 결과에서는 Glu-G에서 Con-G보다 혈중 glutamine 의 수준이 유의하게 높은 것으로 확인되었다. 둘째, Glu-G은 트레드밀 운동을 실시한 후 Con-G에 비하여 혈중 ammonia 의 수준이 유의하게 낮았다. 사전 glutamine 을 섭취하기 전 그룹 간 혈중 ammonia 의 농도에는 유의한 차이가 나타나지 않았으나, 7일 간 glutamine 섭취 후 동일한 검사 결과에서는 Glu-G에서 Con-G보다 혈중 ammonia 의 수준이 유의하게 낮은 것으로 확인되었다. 셋째, Glu-G은 트레드밀 운동을 실시한 후 Con-G에 비하여 혈중 lactate acid 수준이 유의하게 낮았다. 사전 glutamine 을 섭취하기 전 그룹 간 혈중 lactate acid 농도에는 유의한 차이가 나타나지 않았으나, 7일 간 glutamine 섭취 후 동일한 검사 결과에서는 Glu-G에서 Con-G보다 혈중 lactate acid 수준이 유의하게 낮은 것으로 확인되었다. 넷째, Glu-G은 트레드밀 운동을 실시한 후 Con-G에 비하여 혈중 CK의 수준이 유의하게 낮았다. 사전 glutamine 을 섭취하기 전 그룹 간 혈중 CK의 농도에는 유의한 차이가 나타나지 않았으나, 7일 간 glutamine 섭취 후 동일한 검사 결과에서는 Glu-G에서 Con-G보다 혈중 CK의 수준이 유의하게 낮은 것으로 확인되었다. 결론적으로 glutamine 의 섭취는 장시간 고강도 신체훈련을 반복하는 근대 5종 선수들의 혈중 glutamine, ammonia, lactate acid 및 CK의 변화에 긍정적인 영향을 미칠 수 있는 것으로 확인되었다. 즉, 7일 간의 glutamine 섭취는 혈중 glutamine 감소를 완화시켜 줄 수 있는 것으로 확인되었으며, 운동 지속시간이 장시간일 경우 그 효과가 더욱 유의하게 나타날 가능성이 있을 것으로 판단된다. glutamine 섭취에 의한 근 피로 감소의 효과를 확인하기 위해 혈중 ammonia 와 lactate acid 의 수준을 확인한 결과 Con-G에 비해 유의하게 낮은 수준으로 나타난 바, glutamine 의 섭취가 근 피로를 감소시키는데도 긍정적인 효과가 있을 수 있다는 결론을 도출하였다. Glutamine 의 섭취는 혈중 CK의 감소에도 긍정적인 효과가 있는 것으로 확인되어 근 손상의 감소를 위해 섭취를 고려해 볼 수 있을 것으로 판단된다. 다만, CK 감소를 고려하여 glutamine 을 처치하는 상황이라면, 운동 강도의 측면을 우선적으로 파악하여 glutamine 을 처치하는 것이 바람직하다고 판단된다. 따라서 최적의 glutamine 효과를 기대하기 위해서는 우선적으로 고려하는 요인에 따라 운동 강도 및 지속시간에 따라 glutamine 을 처치하는 세밀한 계획이 선행되어야 할 것으로 판단된다.

The purpose of this study is to identify the effects of intake of glutamine on changes in glutamine, ammonia, lactic acid and CK in the blood after prolonged exercises with sub- maximal intensities targeting modern pentathlon athletes. 14 male modern pentathlon athletes were selected randomly as subjects of this study and were divided into a group of treatment with glutamine (Glu-G) and a group of no treatment (Con-G). The treadmill exercise was carried out at 75 % O2max for 90minutes. Incase of Glu-G, 100 mg․kg-1 of glutamine was given in a day for 7 days and the following conclusions were obtained. First, it was shown that the level of glutamine in the blood after the treadmill exercise was significantly higher in Glu-G than that in Con-G. It was shown that there was no significant difference in concentration of glutamine in the blood between two groups prior to intake of glutamine. In result of the same test after intake of glutamine for 7 days, it was confirmed that the level of glutamine was significantly higher in Glu-G than that in Con-G. Second, it was shown that the level of ammonia in the blood after treadmill exercise was significantly lower in Glu-G compared with that in Con-G. It was shown that there was no significant difference in concentration of ammonia in the blood between two groups prior to intake of glutamine. In result of the same test after intake of glutamine for 7 days, it was confirmed that the level of ammonia was significantly lower in Glu-G than that in Con-G. Third, the level of lactic acid in the blood after treadmill exercise was significantly lower in Glu-G compared with that in Con-G. It was shown that there was no significant difference in concentration of lactic acid in the blood between two groups prior to intake of glutamine. In result of the same test after intake of glutamine for 7 days, it was confirmed that the level of lactic acid was significantly lower in Glu-G than that in Con-G. Fourth, the level of CK in the blood after treadmill exercise was significantly lower in Glu-G compared with that in Con-G. It was shown that there was no significant difference in concentration of CK in the blood between two groups prior to intake of glutamine. In result of the same test after intake of glutamine for 7 days, it was confirmed that the level of CK was significantly lower in Glu-G than that in Con-G. In conclusion, it was confirmed that the intake of glutamine could give the positive effect on changes in glutamine, ammonia, lactic acid and CK in the blood of modern pentathlon athletes who repeated physical training with high intensity for a long time. In other words, it was confirmed that the intake of glutamine for 7 days could mitigate the reduction of glutamine in the blood. It was thought that it would be likely that the effect was more effective if prolonged time for exercise was long. In order to examine the effect of reduction of muscle fatigue caused by intake of glutamine, the levels of ammonia and lactic acid in the blood were examined. Results showed that these were significantly lower in Glu-G than them in Con-G. The conclusion was drawn in which intake of glutamine gave the positive effect on reduction of muscle fatigue. Since it was confirmed that intake of glutamine gave the positive effect on reduction of CK in the blood, it was thought to consider the intake of glutamine in order to reduce the muscle damage. However, in a situation to give a treatment with glutamine with a consideration of reduction of CK, it was thought to be desired that glutamine was treated after the aspect of exercise intensity was identified. Therefore, in order to expect the most optimal effect of glutamine, the detailed plan to give the treatment of glutamine should be created depending on exercise intensity and duration time according to preferred factors to be considered.
