This study was designed to determine whether differences in physiological cost index (PCI) exist between elderly individuals operationally defined as fit and nonfit. Twenty-six elderly people were studied and divided into either a nonfit or fit group. The nonfit people did not participate in any formal exercise program. whereas the people in the fit group walked for 20 minutes a minimum of three times a week. The results of this study indicate that endurance was enhanced in the fit group as demonstrated by a statistically significant reduction in PCI. In addition, the PCI provides effective documentation for endurance changes that occur as a result of involvement in a submaximal walking program. This study suggests that submaximal walking programs for elderly people should
