We studied the cortical activity in motor area and the concomitant cardiovascular responses during resting preparatory period either with sustaining handgrip exercises in 6 healthy subjects. Using near-infrared spectroscopy, we measured hemoglobin concentration changes in the bilateral primary motor cortex and premotor cortex and evaluated the correlation between differential values of the oxyhemoglobin concentration changes and heart rate changes. The differential values of the oxyhemoglobin concentration in motor area were positively correlated with heart rate changes. These results demonstrate that the increases in HR was coupled with the increases in cortical activation resulting from a preparation for exercise.
