PROBLEM TO BE SOLVED: To provide an apparatus for estimating the fundamental physical condition of a person.SOLUTION: A plurality of indicators indicative of changes in states of a biological adjustment function elements, including indicators caused by fluctuations closely related with a brain function, autonomic nervous function, physical/mental fatigue, or sensation obtained by biological adjustment function element determination means 200 are calculated at their respective preset determination time points and their time-series changes are determined. Each time-series change is analyzed in the order of priority by a fundamental physical condition estimation means 300. The physical condition can thus be determined from a basic fluctuation performance of a human adjustment system corresponding to a fundamental physical condition estimation time which is set longer than the determination time of each biological adjustment function element.SELECTED DRAWING: Figure 2【課題】人の基礎的な体調を推定する装置を提供する。【解決手段】生体調節機能要素判定手段２００から得られる脳機能、自律神経機能、肉体・精神疲労又は感覚との関連性の高いゆらぎに起因する指標を含む、生体調節機能要素の状態の変動を示す複数の指標を、それぞれ予め設定された所定の判定時間毎に算出し、その時系列変化を求める。基礎的体調推定手段３００により、各時系列変化を優先順位に従って分析する。これにより、各生体調節機能要素の判定時間よりも長く設定される基礎的体調推定時間に対応した人の調節システムの基本となるゆらぎ性能から体調を求めることができる。【選択図】図２
