However, the results have been equivocal. One of the reason why these results are not consistent is provably the problem of measurement. In fact, the definition of 'baseline,' preexperimental physiological response without any stress, differs in each study from one another. The present study seeks to answer what we should regard as 'true' baseline and examines a) whether heart rate (HR), diastolic blood pressure (DBP), and systolic blood pressure (SBP) in the same time are identical in the different 3 days, b) whether it affects these physiological responses to give notice of a stressful task (Stroop Color-World Test), C) in baseline period, what minute should be excluded from the data as adaptation time, d) after task, How soon the responses recover baseline. The results suggest that 1) the baselines of the cardiovascular responses in the same time of the different days are identical if no task is given, 2) but DBP's and SBP's in the day with the task are significantly higher than that with no task, 3) in general, DBP and SBP are not stable in 20 minutes' baseline in contrast with HR's stability, and longer period might be necessary for baseline measurement, 4) the HR's recovery to baseline is rapid (2 Minutes after the end of the task) but SBP's and DBP's are so slow that 5 minutes is provably insufficient. Necessity of more strict and practical experimental design are put forward in the discussion.}, pages = {225--237}, title = {タイプA研究における心臓血管反応測定に関する基礎的研究}, volume = {38}, year = {1997}, yomi = {オオクニ, ヨシノリ and ヒラ , シンジ and スギノハラ, マサズミ} }
