Electroencephalographic recordings were taken from eight high-level male karate performers as they performed an easy and a hard karate training task, namely the breaking of one and three inch-thick boards of wood. Examination of activity in the alpha waveband provided only partial support for a differential pattern of engagement between the left and right hemispheres. There was stronger evidence for an overall increase in alpha waveband activity immediately prior to performance that was most noticeable during the hard task. Some alternative explanations for these observations were eliminated by the design and electrode montage used. The results and implications were discussed in light of other sport related studies and work in the field of hemispheric specialization.
