Abstract
ObjectivesThe aim of this study was to determine the peak running velocity on the track field (Vpeak_TF) based on the laboratory treadmill test (Vpeak_T), and relate the Vpeak values as well as their correlation with the 10-km running performance in trained endurance runners.MethodTwenty male trained endurance runners (age: 29.5 ± 5.3 years; V̇O2max: 67.5±17.6 ml · kg-1·min-1) performed three maximum incremental tests to determine the Vpeak: one for Vpeak_T determination and two to obtain Vpeak_TF on the official track field (400 m), and a 10-km running performance. During the incremental tests, maximum heart rate (HRmax), maximal rating of perceived exertion (RPEmax), and peak lactate concentration (LApeak) were determined.ResultsThe results showed significant difference between the Vpeak_TF and Vpeak_T (18.1 ± 1.2 vs. 19.2 ± 1.5 km·h-1, respectively), as well as the total time of the tests, the distance traveled and the RPEmax determined during the tests. A high correlation was observed between the Vpeak values (r = 0.94), and between Vpeak_TF and Vpeak_T with 10-km running performance (r = -0.95 vs. r = -0.89, respectively).ConclusionsThe good agreement and association with Vpeak_T and high correlation with 10-km running performance demonstrate that the novel track field test is efficient for Vpeak_TF determination.
Highlights
The assessment of aerobic variables for the prescription of endurance running is important when considering the training process [1, 2], to determine possible adaptations and prescriptions of training intensities

Summary
The assessment of aerobic variables for the prescription of endurance running is important when considering the training process [1, 2], to determine possible adaptations and prescriptions of training intensities. These variables are generally determined in laboratories under controlled conditions [3, 4], the applicability of the results in daily practice conditions is still questionable [5]. Some studies have not compared Vpeak_T with the Vpeak obtained on the track field (Vpeak_TF) test based on this wellestablished laboratory treadmill test [8, 9]
