Speed dependence of the Rockport fitness walking test

Introduction: The Rockport Fitness Walking Test is a submaximal test that predicts V02ma" to be used in fitness assessment and exercise prescription. This test requires subjects to walk at a brisk pace. However the ability to predict V02max is unknown when walking at paces slower than a brisk walk. Methods: Healthy adults (N = 35) performed a GXT following a modified Balke protocol to obtain V02max and VT. All subjects also completed two 1-mile walk tests. The first walk test followed the Rockport Fitness Walking Test protocol, completing the test at a brisk pace. Other than walking at a comfortable pace, the second walk test also followed the Rockport Fitness Walking Test protocol. V02max from the GXT was compared to the prediction ofV02max from the brisk and comfortable walk tests. Results: Total walk time, lap time, and HR were all higher for the brisk pace in comparison to the comfortably paced walk, while RPE was lowest for the comfortable pace walk. The brisk walk was better able to predict V02max and VT. Conclusion: The Rockport Fitness Walking Test must be performed at a brisk pace or higher to accurately predict V02max
