摘要:	Objectives:This study proposed that Mu (8–13 Hz) and SMR (12–15 Hz) readings in the sensorimotor corticalarea can be used to investigate the cognitive mechanisms underlying optimal motor performance.Design:This study used a within-subject design.Method:Forty expert golfers were recruited to perform 60 putts while their EEGs were recorded. The puttingdistance was chosen to ensure that approximately 50% of all putts would be missed so that there was a need forconstant adjustments to be made during performance. Successful performance was defined as the ball going inthe hole.Results:(a) Lower Mu power in Cz, and alpha power in Pz and Oz were observed for successful performancescompared with unsuccessful performances at T1 (−2000∼−1000 ms); (b) Higher SMR power in Cz was ob-served for successful performances relative to unsuccessful performances at T2 (−1000∼0 ms).Conclusions:Thesefindings not only support the multi-action plan model (MAP) and the psychomotor efficiencyhypothesis, but also reveal the temporal dynamics of the cognitive mechanisms in an optimal-controlled state.
