Meanwhile, going to hit the ball requires excellent attention for an individual student. Exhibiting gamma waves further influence arrangements of hitting performance. The objectives of this study were first, to determine the negative functional correlation between gamma brain waves and hitting skills, then second to know the positive functional correlation between attention and hitting skills and third to determine the effect of attention on increasing hitting skills. The method used in this research is an experimental method with a one-group pretest-posttest design research design. The sampling technique in this study was using a saturated sampling technique. This investigation amounted to 20 subjects, in the calculation of the Pearson product-moment correlation test using SPSS v.23. The first results collected were p-value 0.026 with an r square value of 0.25, so there is a significant negative functional correlation between gamma brain waves and hitting skills in softball learning of 25%. The second issue obtained p-value 0.017 with an r square value of 0.28, so there is a significant positive functional correlation between attention and hitting skills in softball learning by 28%. Furthermore, thirdly, the results obtained p-value 0.0001 between pre-test and post-test, with a significant increase in skills of 70.17%, so there is a significant influence between attention and hitting skills.

Introduction The optimized state of performance reached by sport elites offers a privileged domain for studying the different neuronal oscillations linked to sensorimotor and cognitive control getting to final success or failure[1]. The human brain is the various vital glands for all life perspectives, including regulating all body functions, responding to all physical activities, and in the thought process in determining decisions. The human brain adapts to changing demands by altering its functional and structural properties neuroplasticity, which results in learning and acquiring skills[2]. Brain development, or learning, is the process of creating, strengthening, and discarding connections among the neurons; these connections are called synapses. Synapses organize the brain by forming pathways that connect the parts of the brain governing everything we do — from breathing and sleeping to thinking and feeling[3]. Brain is an organ that is easily affected by the physical changes, especially in modern times, when the increasing pollution quickly poisons people. When the poisonous substances enter the body, every organ, including the brain, will be endangered. Abnormalities will occur to the brain in terms of attention,
