1. Because BCAAs will also participate in energy supply during exercise, especially for long-term endurance exercise, the total energy supply of BCAA accounts for 60% of the total amino acids.
2. BCAA can stimulate insulin release and promote muscle protein synthesis, which can prevent muscle decomposition.
But these feelings are relatively low. The most direct help for training is that it can help the central anti fatigue.
When we are in the later stages of exercise, low blood glucose levels and low muscle glycogen stimulate gluconeogenesis of muscle protein (muscle decomposition to energy).
Then BCAA will be decomposed first. When the level of BCAA is low and the level of tryptophan is high, tryptophan will enter the brain and make the central nervous system fatigue. Therefore, supplementing BCAA can delay the central nervous system fatigue.
Is that the higher the leucine ratio, the better? no
The best ratio is 2:1:1. When the ratio of leucine is too high, it will inhibit the absorption of other amino acids.
