Brain function is crucial in achieving peak performance. This can determine a person’s motor control and psychological state, such as motivation, attention, goal setting, memory, self-control, decision-making, and concentration. Spontaneous activity of various physical organs such as the brain, heart, and muscles can be a reference when this behavior occurs. This protocol paper aims to determine whether brain exercises can influence athletes’ brain wave activity and concentration levels. The quasi-experimental method used a pretest-posttest control group design involving 68 futsal athletes. Group 1 will use Brain Gym with instrumental music, Group 2 will use Brain Gym with aromatherapy, and Group 3 will use Brain Gym with both aromatherapy and instrumental music. The research will take place at UNPARI, Lubuklinggau, South Sumatra. The results of this research can serve as a basis for developing mental training methods based on the psychophysiological impact of brain wave activity and athletes’ concentration. This highlights the need for better-designed training programs to optimize performance.
