Abstract

The purpose of this study is to investigate the effects of BCAA and additional OKG or albumin supplementation on energy metabolism and hormone changes in prolonged submaximal exercise. The subjects of this study were 5 male college students, and they took participated in each experiment. In each experiment (control, BCAA, BCAA+OKG, BCAA+albumin), the subject ran for 90 minutes on the treadmill. Blood was drawn and analyzed as glucose, FFA, ammonia, growth hormone, insulin, cortisol, $T_3$, and $T_4$. The obtained results were analyzed via two-way repeated ANOVA using SPSS program. A value of p<.05 was considered statistically significant. The concentration of glucose was the lowest in the BCAA supplement group, and there was significant difference between times of exercise (p<.05). In concentration of FFA, there was a significant difference between times of exercise and supplemented groups (p<.05). The concentration of blood ammonia was the lowest in the BCAA+albumin supplement group, and was the highest in the BCAA supplement group. Concentration of growth hormone, cortisol, $T_3$ and $T_4$ were increased as exercise progressed and decreased after all exercise. But concentration of insulin was decreased as exercise progressed. In these results, BCAA and additional OKG or albumin supplement with BCAA may make better effect to the increasing energy generation and inhibiting protein degradation during prolonged submaximal exercise.

이상의 연구를 종합해보면, 장시간 운동시 BCAA 투여는 BCAA 산화시 발생되는 암모니아 등의 피로물질 축적에 의해 운동수행에 부정적 영향을 미칠 수도 있으나, 체내 글루코스가 소진되어가는 시점에서 유용한 에너지원으로 기여 되어 운동수행에 도움이 될 수 있다고 보여진다. 또한 OKG나 알부민을 가중투여하면 크렙스 사이클의 중간물질로 또는 유리지방산 동원의 운반자로서 BCAA 단독 투여시 부정적으로 나타난 원인을 해결하여 운동수행에 긍정적 영향을 기대할 수 있을 것으로 사료된다. 그러나 운동과 BCAA, 그리고 내분비 체계와의 관계는 각 호르몬의 역할과 기능에 따라 도출되는 결론이 다를 수 있어, 앞으로 BCAA 대사와 관련된 효소반응 등에 대한 추가적인 연구가 필요하다고 본다.
