What is it about?
This study found that the combined supplementation of branched-chain amino acids, arginine, and citrulline can maintain the ability to identify the opponent's movement and hit the ball to the opposite direction. In tennis and many other sports, the athletes tend to make more mistakes in recognizing or predicting the opponent's movements when they are tired. Or even when they can still recognize the opponent's movements but can not hit the ball to the desired direction and/or spots. These supplements can help the athletes to maintain these abilities after 2 hours of tennis match.

Why is it important?
This study showed the improvement in the mind, and the executions that require the coordination among eyes-brain-hands. Most studies only investigated the physical performance, such as racquet speed or ball speed. This study explores an important, but rarely studied, ability in tennis (and many other sport) competition. It also emphasizes the benefit of these supplements.
Perspectives
Physical fatigue, such as playing tennis for 2 hours, would lead to worse decision making in strategies and inability to execute the racquet. This study used a test that is similar to real tennis competitions. The supplements, BCAA, arginine, and citrulline, can help maintain these abilities when the players are tired. It would benefit the athletes at the later stage of a match.
