Outline of Final Research Achievements

Motor performance of simultaneous control of transitory bilateral upper limbs exercise and periodic segment lower limb exercise and contingent negative variation (CNV) were recorded. Degree of interference between the upper and periodic waist rotation was changed by execute timing of the upper limbs. The change of CNV amplitude was corresponded to the interference degree. These changes were not observed periodic hip joint flexion, knee joint flexion and ankle dorse flexion. These data suggest that the waist rotation play an important role for automatization of lower limb exercise. And attention for simultaneous control of the upper limbs exercise and waist rotation may differ with execute timing of the upper limbs exercise.
