We investigated the endurance of elderly people using the "120 pitch step method". The purpose of this study was to clarify the transition of oxygen uptake (Vo
2), heart rate (HR) and systolic blood pressure (SBP) using the "120 pitch step method", and to investigate the relationship between the Vo
2 of Anaerobic Threshold (AT) and HR, SBP of the "120 pitch step method". Five healthy women with an average age of 64.8±2.4 performed the "120 pitch step method" for six minutes. Their endurance was tested with a cycle ergometer. Steady states of HR and SBP appeared by the 5 minute point in the "120 pitch step method". Steady states of Vo
2 appeared in only 2 people (Subjects B and C). Their Vo
2 at the steady states were 13.8 ml/kg/min and 15.1 ml/kg/min. The average of Vo
2 at AT was 13.2±3.9ml/kg/min. There were correlations between the Vo
22 at AT and HR, SBP in the "120 pitch step method" (HR: r=-0.85, SBP: r=-0.50). Endurance was so high that HR and SBP were low. Those results show that the "120 pitch step method" over 5 minutes may be able to measure the endurance capacity of elderly people. But further examinations are required for applying this to elderly people who are living in the community.
