The 6- and 12-minute walking tests are widely used field tests that have been developed from the Cooper's test to allow testing of a patient population. When performed with maximal effort by fit subjects the distance covered in the 12-minute run has been shown to correlate with maximum oxygen uptake. The appropriate walking speed can be selected based on the patient’s performance in the incremental shuttle walking test, or by estimating the correct speed for the individual.Ĭooper’s 12-minute running test is an example of an internally paced test in which the subject is asked to cover the greatest distance possible in the set time of 12 minutes. There are a range of set walking speeds provided in the test, from 1.8 to 6 km/h.

The test has a series of recorded bleeps the same distance apart to allow a set pace to be maintained in between the cones. The Endurance Shuttle Walking test had been developed to allow sub-maximal steady-state exercise testing. The ISWT was developed for exercise testing in patients with chronic obstructive pulmonary disease (COPD), but has been validated in other patient groups such as those with cardiac failure and low back pain. A relationship between the number of shuttles completed and maximum oxygen uptake has been demonstrated therefore it is possible to estimate maximal oxygen uptake from the distance covered during the ISWT and the Multistage Fitness Test. The outcome of these shuttle tests is the number of completed shuttles, i.e. The Modified Shuttle Walking test contains additional increments to allow testing of fitter patients. The person being tested is required to walk a distance of 10 m between the timed bleeps. The pace of the test is initially very slow, which allows testing of severely compromised subjects. The Incremental Shuttle Walking Test (ISWT) was developed from the Multistage Fitness Test to provide a standardized, externally paced exercise test suitable for a more limited population. The end points of the test are the second time the person fails to reach the marker before the bleep sounds, the person terminating the test voluntarily or the tester halting the test due to safety factors, e.g. Every minute a triple signal indicates that the bleeps are getting closer together therefore the person under testing must increase their speed in order to reach the marker before the next timed bleep sounds. The signals indicate the time allowed to run a 20 m course between two markers. It is based on a series of recorded timed signals (bleeps). The Multistage Fitness Test, commonly known as the ‘bleep test’, is a standardized, externally paced, incremental field running test. The use of pace setting also allows an incremental test to be carried out, as pacing can produce a gradual increase in speed up to maximal exercise. These tests most often use walking, running or step-ups, but may be made up of more functional tasks such as sit to stand.įield-based exercise tests may be internally paced, that is the patient determines how fast they walk or step, or they may be externally paced, that is when the patient is required to pace their activity in time with a signal, such as the bleep test or a metronome.Įxternally paced tests allow a standardized protocol, and may be less influenced by encouragement. In The Physiotherapist's Pocket Guide to Exercise, 2009 Field-based exercise testingįield-based exercise tests are widely used in clinical practice as they require little equipment and use simple activities that are familiar to patients.
