This work examined whether prediction models based on a 2‐km walking test are valid for predicting the Vo 2max of middle‐aged, healthy, moderately to highly physically active adults. Sixty‐seven 35‐ to 45‐year‐old moderately active men and women and 44 35‐ to 55‐year‐old healthy men who participated regularly in marathon‐long sports competitions were studied. Vo 2max was determined in an uphill walk‐run on a treadmill. The 2‐km walking test was conducted on a flat outdoor course. The subjects walked the distance as fast as they could. Walking time, heart rate at the end of the walk, age and body mass index were entered in the prediction formulas as established in the original study. The total errors of prediction and the correlation coefficients between the measured and predicted Vo 2max (ml‐kg −1 min −1 ) for the moderately active women and men and for the competitors were 5.2, 5.7 and 7.7 ml kg −1 min −1 and 0.55, 0.79 and 0.60, respectively. The measured relative Vo 2max was slightly underpredicted in all groups. The results suggest that the 2‐km walk test is a reasonably valid test of maximal aerobic power for moderately fit men and women, but less valid for very fit individuals.
