Introduction: A Sprinter starter is a complex skill that, not only are physiological and biomechanical determinants of starter function, but also psychological factors affect it. Currently, neurofeedback (nerve feedback) is referred as a method for self-regulation of brain waveform (EEG) and an applied program to facilitate the achievement of peak performance. The purpose of this study is to investigate the effect of neurofeedback training on the velocity and coordination joint pattern in Sprinter starter in female elite runners. Perry (2011), demonstrated athlete mastery of self- regulation skills and improvement in sport performance by Neurofeedback training.
Methodology: In this semi-experimental research, 20 elite runners participated (control = 10 Person, test = 10 Person). Subjects completed three Optional start and five Selected start. The kinematic data of the subjects was collected for analyzing of start motion. The experimental group performed 15 sessions of neurofeedback training, including the alpha enhancement protocol in the 3T region of the SMR protocol in the 3C and 4C regions, along with their training, and the second group continued their usual exercises. The post-test was similar to the pre-test for both groups. To find the coordination joint pattern, the CRP method and the total speed of the person at 10 m and the angular velocity of the lower extremities were calculated in the first two steps of the starter.
Results: Considering that the brain waves of subjects in all three areas showed a significant increase, but there was no significant difference between the total velocity and angular velocity of the organs in the optional and selective start of pre-test and post-test. Also, the control group compare to the experimental group showed more changes in the pattern of joints coordination in the post-test. It can represent a relatively stable pattern of coordination of the experimental group compared to the control group.
Discussion: According to the results of this study, use of neurofeedback exercises can be recommended to increase the relative stability of coordination patterns for elite runners. further studies need, regarding the effect of this training method on improvement of velocity function.
