Bruce Treadmill TestTesting and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made. In the analysis, we need to consider the factors influencing the results. ObjectiveThe objective of the Bruce Treadmill Test (Bruce 1972)^{[1]} is to monitor the development of the athlete's general endurance (VO_{2 }max).
How to conduct the test
Converting from Percent Grade to DegreesAssessmentActive and sedentary men  (Foster et al. 1984)^{[2]}From the total walk/run time, an estimate of the athlete's VO_{2} max can be calculated as follows:
"T" is the total time of the test expressed in minutes and fractions of a minute, e.g. 13 minutes 15 seconds=13.25 minutes Active and sedentary women  (Pollock et al. 1982)^{[3]}From the total walk/run time, an estimate of the athlete's VO_{2 }max can be calculated as follows:
"T" is the total time of the test expressed in minutes and fractions of a minute. For an analysis of your VO_{2 }max score, see the VO_{2 }max page.
AnalysisThe test result is analysed by comparing it with the athlete's previous results for this test. With appropriate training between each test, the analysis is expected to indicate an improvement in the athlete's VO2 max. Target GroupThis test is suitable for active and sedentary individuals but not for those where the test would be contraindicated. ReliabilityTest reliability refers to how a test is consistent and stable in measuring its intended 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 influencing the results and the test reliability. ValidityTest validity refers to the degree to which the test measures what it claims to measure and the extent to which inferences, conclusions, and decisions based on test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development. There are published VO_{2 }max tables, and the correlation to actual VO_{2 }max is high. For an assessment of your VO_{2 }max, see the VO_{2 }max normative data tables. Advantages
