The 1-mile Rockport walking test is a submaximal test used to estimate cardiorespiratory fitness (VO2 max) through a brisk, 1-mile walk. The time taken to complete the walk and post-walk heart rate are entered into a formula to calculate VO2 max. This indirect test requires minimal equipment and is suitable for varied fitness levels. Results are compared to normative data tables to assess fitness classification from poor to superior. The reliability and validity of results depend on strict test administration and individual motivation during the walk.
3. Cardio-respiratory Fitness
Cardiorespiratory fitness is important because it provides a measure of
how efficient the cardiovascular and the respiratory system must work
in order to take in and deliver oxygen to every cell in the body.
During exercise, the demand for oxygen increases and so the
cardiorespiratory system must increase its workload in order to match
this demand.
There is a positive correlation between oxygen demand and
workload/exercise intensity.
4. The maximal oxygen uptake or aerobic
capacity or VO2 max
The maximal oxygen uptake (aerobic capacity, or VO2 max) is widely
accepted as the criterion measure of cardiorespiratory fitness.
VO2 max is the maximum amount of oxygen that an individual can
consume, deliver and use in a minute to fuel intense physical activity or
exercise.
Aerobic capacity is usually expressed as milliliters of oxygen used in
one minute per kilogram of body weight (ml/kg/min-1.0).
5. The maximal oxygen uptake or aerobic
capacity or VO2 max
Most direct tests of VO2 max uses a gas analyzer and require that
the participant works to exhaustion.
There is a positive and somewhat linear relationship between heart
rate and oxygen consumption
Therefore, it is possible to estimate VO2 max using indirect tests like
Harvard Step Test and the 1-mile walking test without having to
subject participants to the physical stress and discomfort of a
maximal test.
6. THE ONE-MILE ROCKPORT
WALKING TEST
The one-mile walking test is an evaluation of cardiovascular fitness,
that seeks to predict an individual’s aerobic capacity (VO2 max)
The Rockport walking test was developed in 1986 by physiologists and
cardiologists at the Department of Exercise Science at the University of
Massachusetts at Amherst.
The test is both indirect and sub-maximal in nature, making it
considerably easier to implement in field-based scenarios
7. THE ONE-MILE ROCKPORT
WALKING TEST
The study found that there were no significant differences in
the number of points scored during the Rockport Test when
compared to the points scored in the 1.5-mile run.
Furthermore, there were also no significant differences
between the average and predicted VO2 max.
8. THE ONE-MILE ROCKPORT WALKING TEST-
Target Group
The one-mile walking test is designed for
both men and women aged 20-69 years of
varying levels of fitness.
As the test only requires a participant to
perform a brisk walk, it is also suitable for
deconditioned participants, older adults, or
those that are overweight.
9. THE ONE-MILE ROCKPORT WALKING TEST-
MATERIAL REQUIRED
To conduct this test, you will require:
400-metre track
Stopwatch
Weighing Scale
Assistant
Heart Rate Monitor (Optional)
10. THE ONE-MILE ROCKPORT WALKING TEST-
PROCEDURE
Ask the assistant to weigh and records the subject’s Body Weight
Mark the Starting and finish points in the track
Instruct the athlete to warms up for 10 minutes
Ask the assistant to give the command “GO”, starts the stopwatch
Instruct the subject to walk and complete 1 mile (1609 meters) distance as fast as
possible
The subject should make every effort to push himself/herself, but should avoid jogging.
Record the time taken for the subject to complete the test
Measure the heart rate of the subject immediately on finishing
Alternatively You can attach the heart rate monitor before the start of the test and
ensure that it is correctly measuring heart rate. (Optional)
11. THE ONE-MILE ROCKPORT WALKING TEST-
ASSESSMENT
The formula (Kilne 1987) used to calculate VO2 max is:
132.853 – (0.0769 × Weight) – (0.3877 × Age) + (6.315 × Gender) –
(3.2649 × Time) – (0.1565 × Heart rate)
Where:
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
14. THE ONE-MILE ROCKPORT WALKING TEST-
ASSESSMENT
For example,
A 30-year-old man weighing 180lbs completed the one-mile walk test in
12 minutes and 15 seconds and his post-test heart rate was 165bpm, VO2
max would be calculated as follows:
VO2 max = 47.88 ml/kg/min
15. THE ONE-MILE ROCKPORT WALKING TEST-
ASSESSMENT
Advantages
Minimal equipment required
Simple to set up and conduct
More than one subject can perform the test at the same time
Disadvantages
Specific facilities required
Assistant required to administer the test
16. THE ONE-MILE ROCKPORT WALKING TEST-
NORMATIVE DATA
Once a VO2 max value has been calculated, refer to the
normative tables to determine an appropriate classification
Analysis of the result is by comparing it with previous tests'
results. It is expected that, with appropriate training between
each test, the analysis would indicate an improvement.

Reliability
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 various factors that may influence the results and therefore,
the test reliability.
Validity
Test validity refers to how the test measures what it claims to measure and the
extent to which inferences, conclusions, and decisions made based on test scores
are appropriate and meaningful. This test provides a means to monitor training on
the athlete's physical development. For assessing your VO2 max see the VO2 max
normative data tables.
