Outline of Final Research Achievements |
Movement-related cortical potentials (MRCP) is a negatively sloping cortical potential, setting in around 2 s prior to a voluntary movement. It is also known that MRCP is observed preceding volitional contraction and relaxation. In the present study, we examined how MRCP observed during sports-specific movement such as Archery and Japanese archery which required muscle relaxation. Participants (Archery; n=16, Japanese archery; n=17) performed 40 shots with EEG system (64 channel) on the scalp and EMG recordings of right limb. During Archery shot, as a result, larger RP amplitudes and later RP onsets were observed in relatively skilled group. During Japanese archery, there are individual differences in MRCP amplitude and latency.
