Research Abstract

We examined the effects of long-term exercise on output mechanism in the brain and motor conduction velocity and distribution of the motor nerve conduction velocity by measuring MCV and DMCV of the athletes and non-athletes.
The following results were obtained ;
1.The significant difference was not found between athlete and non-athlete about the degree of muscle contraction following reaction movement.
2.The late CNV was higher in the athletes than non-athletes. But, the significant difference was not found between athlete and non-athlete with regard to count task.
3.Motor potential was the higher in the athlete than healthy human. Moreover, motor potential was the longest over the supplementary area.
4.The motor nerve conduction velocity (MCV) in the athletes was faster than in the non-athletes. The distribution oft motor nerve conduction velocity (DMCV) peak was faster than in the non-athletes. A positive correlation was found between MCV and DMCV.
Accordingly, it may be concluded that the long-term exercise influences output mechanism in the brain and the conduction velocity of spinal motoneuron.
