| Outline of Final Research Achievements |
Running speed in a short-distance sprint gradually decreases after reaching the maximum. The deterioration of sprint motor performance could be account for by a decrease in descending commands from the central nervous system to active muscles. Direct current stimulation (DCS) to the spinal cord and motor cortex has been used to modulate and enhance descending commands. Therefore, we investigated how sprint motor performance was modulated after DCS to the motor cortex and spinal cord.
Power during sprint cycling over 30 s was significantly increased after cathodal DCS to the spinal cord. Neither anodal nor cathodal DCS to the motor cortex could not induce improvement of sprint cycling performance. On the other hand, the anodal DCS to the motor cortex could induce improvement of the endurance cycling.
