Background & Study Aim: Reliability is one of the key adequacy criteria for evaluating motor ability tests and their relevance for physical fitness evaluations and also a verified "training trend". The aim of this study was the reliability of the 3-Minute Burpee Test (3MBT) as criterion of verification of "training trend" young women.
Material & Methods: The study involved 72 female students of the University of Warmia and Mazury in Olsztyn (Poland), aged 19-21 years (mean 20.6 ±0.66 years). The reliability of 3MBT was determined based on the calculated values of correlation coefficients between the average number of cycles completed by the participants in 11 repetitions of the test. The "training trend" hypothesis was verified by the Friedman test and post-hoc tests. Heart rate (HR) was measured in the first and eleven repetition (immediately before and after the test, and 30-, 60- and 90 seconds after the test), and the differences between the measured values, including an increase in HR after the test and a decrease in HR 90 s after the test, were determined by the Wilcoxon signed-rank test.
Results: The values of correlation coefficients between successive repetitions of the 3MBT are within the range of very low reliability (0.70 to 0.79) to perfect reliability (0.95 to 0.99). Statistically significant differences between the number of completed cycles in successive trials of the 3MBT point to the presence of a "training trend". These differences are observed up to the fifth repetition of the 3MBT.
Conclusions: The 3MBT can be reliably used to assess endurance and strength abilities among young women. The "training trend" has to be eliminated before the test is used in evaluations of endurance-strength abilities. A minimum of 5 repetitions should be performed for the final test to deliver reliable results.
