An Evaluation of the Canadian Forces Two-Mile Walk as a Test of Aerobic Fitness in Males over 45 Years of Age
Abstract
The Canadian Forces (CF) two-mile walk was evaluated as a test of aerobic fitness for males over 45 years of age. Twelve male subjects aged 46-61 years were first classified into one of four categories of fitness based on predicted values of minimum oxygen uptake (VO2 max) determined by a submaximal bicycle ergometer test. Subsequently the same individuals performed the CF two-mile walk test and their performances were categorized according to the times listed as standards in the Canadian Forces Administrative Order (CFAO) 50-1. Since VO2 max is accepted criterion of aerobic fitness, it was possible to evaluate the two-mile walk by comparison. The results indicate that the two- mile walk test considerably overestimates fitness and, from theoretical considerations, it is suggested that the walking times in CFAO 50-1 should be reduced by approximately four minutes. This study also examined the two-mile walk as a means of improving aerobic fitness in males over 45 years of age. Heart rates recorded by telemetry during the walk reached a training level (60% or more of cardiac reserve) in ten of the subjects for at least ten minutes. By this criterion, walking at 4-5 mph for two miles three times a week should improve aerobic fitness in sedentary males over 45 years of age. (Author)
