The Effects of Model Skill Level on Mu Rhythm Suppression in Basketball Lay- up Shot
Abstract:
Mu rhythm suppression is thought to accompany the activation of the mirror neuron system which occurs when a human observes or imitates the behavior of others. The purpose of present study, was to examine the effects of model skill level on mu rhythm suppression in Basketball Lay-up shot. 13 Physical education students of Tehran Shahid Rajaee Teacher Training University (mean age: 22.2±1.5 years) voluntarily participated in this study. The demonstration’ order was counterbalanced across participants. They randomly divided into the two groups: one group is observed skilled model, followed by unskilled model, and the other is observed unskilled model followed skilled model. Participants’ Brain Waves were recorded by EEG in three conditions, open eye resting and observing skilled and unskilled model and were transferred to quantitative data by Neuro-guide Software. Mu rhythm Suppression was calculated as a ratio of the alpha absolute power during observation of both models relative to the alpha absolute power in the baseline condition (rest). Results of repeated measures ANOVA with the within-subject factors revealed that model skill and brain area main effects were significant while interaction effect of both variables were not significant. Results of Bonferroni test showed that the mu rhythm in observing skilled model condition was more significantly suppressed compared to the observing unskilled model condition (P≤0.01). In addition, the suppression of mu rhythm in CZ area was significantly greater than the suppression in C3 (P≤0.05). Action observation can activate the brain areas involved in the performance of an actual task.
