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.
