1 Mile Walk Test Reliability Essay

The purpose of this study was to verify the reliability and concurrent validity of the One-Mile Walk Test (OMWT) (The Rockport Fitness Walk Test, Kline et al., 1987), as a preditor of the maximal oxygen consumption (VO2max) among women aged 70 to 79 years. The study used a convenient sample, composed by 30 healthy seniors from Florianópolis, SC. Data collection was structured in three phases: 1) answering questionnaires on sociodemographics, on readiness for physical activity (PAR-Q) and on physical activity level (IPAQ). Anthropometric variables were measured and the participant performed the first evaluation of the RFWT. Afterwards, the subject visited the laboratory for a treadmill walk and for a trial of the equipments (K4 b2 - COSMED) to be used during the stress test (ST) for directly measuring the VO2max; 2) the seniors performed the ST following an incremental test protocol, from 2.4 km.h-1 to 5.6 km.h-1 with grades varying from 0% to 15%; 3) the second RFWT. The statistical analyses included the criteria suggested by Lohman (1992) for validity and the procedures were performed using the SPSS (v. 7.5) and MedCalc (v. 9.1). The level of significance was established at 5%. For reliability, the generalized (GE) and sex-specific equations (SSE) presented high intraclass correlation coefficients (ICC=0.942 and 0.948, p < 0,001) for predicted VO2max and low standard error of the estimate (1.14 and 1.48 ml For validity, the predicted VO2max was underestimated by both equations (GE=17.11±5.97 ml; SSE=17.15±4.99 ml vs measured VO2max=26.67±3.53 ml (p < 0.001), and low correlation coeficients (r=0.488 and 0.471) between predicted and measured VO2max were observed. The equations presented high constant error (-9.56 and –9.53 ml, with only 16.7% of agreement between the methods. Therefore, the RFWT was reliable, however, not valid for predicting VO2max among active elderly women aged 70 to 79 years.

Rockport Fitness Walking Test

Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made but in the analysis we need to bear in mind the factors that may influence the results.


The objective of this Rockport Fitness Walking Test (Kilne 1987)[1] is to monitor the development of the athlete's VO2 max.

Required Resources

To undertake this test you will require:

  • 400 metre track
  • Stopwatch
  • Weighing scales
  • Assistant

How to conduct the test

This test requires the athlete to walk one mile (1609 metres) as fast as possible.

  • The assistant weighs and records the athlete's weight
  • The athlete warms up for 10 minutes
  • The assistant gives the command “GO”, starts the stopwatch and the athlete commences the test  
  • The assistant records the time taken for the athlete to complete the test and the athlete's heart rate immediately on finishing


I have been unable to locate any normative data for this test.

The formula (Kilne 1987)[1] used to calculate VO2 max is:

  • 132.853 - (0.0769 × Weight) - (0.3877 × Age) + (6.315 × Gender) - (3.2649 × Time) - (0.1565 × Heart rate)


  • Weight is in pounds (lbs)
  • Gender Male = 1 and Female = 0
  • Time is expressed in minutes and 100ths of minutes
  • Heart rate is in beats/minute
  • Age is in years

For an analysis of your VO2 max score see the VO2 max page.


Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.

Target Group

This test is suitable for sedentary individuals but not for individuals where the test would be contraindicated.


Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strict the test is conducted and the individual's level of motivation to perform the test. The following link provides a variety of factors that may influence the results and therefore the test reliability.


Test validity refers to the degree to which the test actually measures what it claims to measure and the extent to which inferences, conclusions, and decisions made on the basis of test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development. For an assessment of your VO2 max see the VO2 max normative data tables.


  • Minimal equipment required
  • Simple to set up and conduct
  • More than one athlete can conduct the test at the same time
  • The test can be administered by the athlete


  • Specific facilities required
  • Assistant required to administer the test
