運動負荷漸増に伴う酸素摂取量と心拍数の関係 : AT(無酸素性作業閾値)との関連から

Is it well-known that the relationship between oxygen-uptake(VO2) and heart rate (HR) is correlative (positive) in the middle level of exercise load. But it is not understood how is the middle level of exercise load for the relationship between VO2 and HR being in order. In this paper we reported the relationship between VO2 and HR with an exercise from points of AT (Anaerobic threshold). To find out the AT of each subjects, VO2, VE(Ventilation expier), VCO2(Ventilation CO2), O2rate(VO2/VE), determinated at the point when there was a rapid increase in VE and when FECO2 started to decrease. The results of the experiment led us to decide: 1) The middle level of exercise load is equal to the level to AnT(Anaerobic threshold). 2) The threshold being equal to AnT is point of transition from aerobic metabolism to anaerobic metabolism.departmental bulletin pape
