近年,心疾患や腎疾患等の患者を対象とした運動療法分野において,最適な運動負荷強度の指標としてAnaerobic Threshold(AT:無酸素性作業閾値)が用いられている.ATの決定については,侵襲的検査(血液分析)または高度かつ高価な計測が必要になることに加え,医師等の経験則に頼らざるを得ないなどその値を定量的に同定できる方法が存在していない.こうした背景から本研究は呼吸パラメータを対象とし,strucchangeによるATの客観的同定を試みることを目的とする.実験方法としては,自転車エルゴメータを用いた負荷漸増運動を実施する.被験者には呼吸代謝測定装置を装着し,各呼吸パラメータを計測,一連のアルゴリズムによるstrucchangeを行い,ATを同定できるように工学的手法を確立する. |

Recently, various exercise has been performed including the participation in citizens' marathon meet in various scenes by a health-oriented surge. Aging rate goes ahead through our country most now in developed countries, it is inevitable that the senior citizens who deteriorated of the ADL (activity of daily living ) increase. In late years, a certain exercise strength index AT(Anaerobic Threshold) comes to be used widely in the field of the exercise physiology. There is a method to measure blood lactic acid value by the drawing blood at the hospital as a method to measure the AT. It is the present conditions that the method is invasive for the human body and measurement technique using an expensive apparatus is necessary and to depend on the law learned by experience of the doctor for AT decision. A purpose of this study is to identify the AT by using the objective technique that does not depend on the laws learned by experience such as doctors. This study showed that the extraction of the confidence interval by each ventilation index was confirmed. In addition, significance of the AT identification was confirmed in the ventilation index item of VE,VCO2 in this study. As descried above, this study suggested that AT identification by strucchange was constant significance . |
