Oxygen consumption, heart rate and blood pressure during bicycle ergometer exercises were measured in order to determine the pertinent indices for the risk control in physical therapy. Subjects were 26 healthy young adults (in the age groups of 20's and 30's), 20 healthy middle aged persons (40's and 50's), 17 healthy elderly persons and 20 disabled elderly persons. The workload consists of bicycle ergometer exercises at load of 20, 40 and 60 watts for the healthy young adult, healthy mjddle aged and healthy elderly group. The same task was given to the disabled elderly group choosing the loads from 10, 20, 30 and 40 watts considering the individual difference in ability. The results were showed as follows. 1) The comparison between men and women yield higher the amount of heart rate, systolic blood pressure and oxygen consumption normalized to body weight for women as against the same external load. The change of systolic blood pressure in men and women and the change of heart rate in women increased remarkably with one's years. 2) The correlation coefficients were calculated between the METs and the proposed indices. Relatively high correlations were found between METs and the increased rate of heart rate (%HR), the changed rate of heart rate reserve (%HRR), the increased rate of pressure rate product (%PRP) and the increased rate of Katz's index (%Katz). 3) The change of heart rate increased predominantly in women and/or elderly as against the same energy cost.
