Abstract

type:Article

本研究は、ヘルスプロモーションにおける体力指標として、相対心拍数/仕事率係数が利用できることを明らかにしたものである。一人の被験者の相対心拍数/仕事率係数および最大酸素摂取量を1年半の間に38回測定し、個人内変動を明らかにするとともに、相対心拍数/仕事率係数と最大酸素摂取量との間に有意な相関関係があることを認めた。

It has shown that the slope of relative heart rate on work rate (Δ%HR/ΔWR) is useful for evaluating a capacity of cardiorespiratory endurance. We measured individual changes of the Δ%HR/ΔWR and the maximum oxygen intake (VO2max) thirty eight times for one and a half years using only one subject who took proper exercise regularly. The Δ%HR/ΔWR were varied from 0.413 to 0.531%W^(-1)kg and the mean value was 0.459±0.026. There was a significant correlation between the Δ%HR/ΔWR and VO〓max(ml/kg)(r=-0.848; p<0.05). This result suggests that the Δ%HR/ΔWR is an optimal fitness sign correspond to individual changes and is useful for assessing a level of physical fitness in Health Promotion.
