A Study on Heart Rate Variability at Rest in a Sitting Position HONDA Kaoru Associate Professor, Psychology & Information, Cultural Systems Course To adequately grasp both physical strain and reaction quantitatively and objectively, it is necessary to compare heart rate variation before and after starting a task with the heart rate at rest before a given task has started. This study measured the heart rate interval (R-R interval) at rest in a sitting position, and also analyzed to what extenttheheart rate varied between eyes-opened and eyesclosed status. The considerable conditions are then accounted for if the heart rate at rest is used as a reference. Results indicated that when the heart rate at rest is measured, the eyesshould be closed to reduce rate variation. In addition, temporal variation of the heart rate at rest should also be checked, in addition to the heart rate just before the start of the workload in order to determine what rate should be used as, "the heart rate at rest".
