Abstract
We examined the reproducibility of performance in running events of 5 and 10 km in running track. Thirty-one recreational, male, runners performed two tests of 5 and two tests of 10 km in an official running track. There was no significant difference in time between the test-retest for both tests using the paired t test (P > 0.05). The intraclass coefficient of correlation and the coefficient of variation were 0.94/3.44% (5 km) and 0.97/2.43% (10 km), respectively. The reproducibility of both running events in running track was similar to that reported in the literature for laboratory tests. In addition, the 10 km test was more reproducible than the 5 km test for this studied sample, requiring approximately half the sample needed to detect significant increases during test-retest in running events of 5 km.
