A new assessment tool of cardiorespiratory endurance has been developed for non-athletes from the viewpoint of the advantages of prediction and simplicity of measurement while using a cost-effective approach. The simple index used in this assessment tool is the slope of the modified relative heart rate (%HR) on work rate (WR) during 1 min. incremental exercise on a cycle ergometer (Δ%HR/ΔWR). The same slope corrected for body mass (Δ%HR/ΔWR・BM) has also been developed. These indices have already been validated. The Δ%HR/ΔWR is based on 1 min. incremental loading not including steady-state values of heart rate (HR)-WR response. The Δ%HR/ΔWR based on 1 min. incremental loading does not express an optimal incremental rate of the modified %HR versus WR. In this study, the Δ%HR/ΔWR based on 5 min. incremental loading including the optimal steady-state values of HR-WR response (5 minΔ%HR/ΔWR) and the 5 minΔ%HR/ΔWR corrected for body mass (5 minΔ%HR/ΔWR・BM) were validated by examining the correlations between the 5 minΔ%HR/ΔWR and maximum oxygen uptake (VO_2max) and between the 5 minΔ%HR/ΔWR・BM and the VO_2max corrected for body mass (VO_2max/BM), respectively, in 14 healthy female students. Consequently, both the 5 min Δ%HR/ΔWR and the 5 minΔ%HR/ΔWR・BM showed highly significant negative correlations with the VO_2max (r=-0.92 ; p<0.001) and the VO_2max/BM (r=-0.90 ; p<0.001), respectively.
