In spite of same work load-heartbeat response was different between gradual increase load stage and gradual decrease load stage. In every condition of decrease stages the load decreased but heartbeat did not decrease in most subjects. As a result of this phenomenon the correlation coefficient between load and heartbeat decreased remarkably. In this stage LF/HF ratio of instantaneous heart rate variation (IHRV) decreased in most subjedts. As peak load increased with PWC130, PWC150, PWC170 conditions, this tendency became stronger. Therefore we can consider that LF/HF ratio of IHRV and heart-beat rate are related to some extent.}, pages = {83--91}, title = {漸増漸減型自転車エルゴメーター負荷への瞬時心拍応答}, volume = {10}, year = {2008} }
