The branched chain amino acids (BCAA’s) that we take during the workout can improve the central fatigue. In fact, this has been proven with psychomotor performance tests. In this article, we are going to explore a new combination: BCAA’s and Ornithine

BCAA’s to Decrease the Fatigue?
The main hypothesis is that one of the reasons we cannot decrease the intra-workout fatigue is due to the hyperammonemia (excess of ammonia) from the amino acid metabolism. In fact, this phenomenon can buffer its beneficial effects on the psychomotor performance.
A research group has carried several studies regarding the use of BCAA supplementation during the workout. In addition, they have suggested its combination with L-ornithine L-aspartate, which is an element that lowers the ammonia levels during exhausting exercise.
Why take BCAA’s during the workout?
Let’s not forget that according to the free tryptophan hypothesis, taking BCAA’s during the workout will increase their plasma concentration. Consequently, the tryptophan brain levels will drop. Therefore, the amount of serotonin in the brain will be low (delaying the onset of central fatigue).
Moreover, they also analyzed the perceived exertion, heartbeat, lactate or the free tryptophan VS BCAA relation
Combining BCAA’s + L-ornithine L-aspartate significantly reduced the plasma ammonia levels during the recovery phase
Likewise, the relation between free tryptophan and BCAA’s was lower in the group that took the previous supplementation. Accordingly, the reaction time to stimuli were better in that same group due to the lower serotonin levels.
The reaction time refers to the average time between the stimulation of a sensorial organ and the beginning of a motor response
A strength workout is similar to how we produce strength per unit of time (RFD, Rate of Force Development). This variable is essential when it comes to measuring how fast an individual can develop strength. Visually, you could observe the speed of the first stages of a movement to overcome the sticking points.
Thus, even though it needs to be supported by similar research, combining 0.04-0.05 of L-ornithine L-aspartate per kg of body weight with BCAA’s could be interesting. In fact, it could be particularly useful for exercises or activities that require a fast reaction capacity. Although this dose is meant for people who do not suffer from obesity.
