Novel track field test to determine V(peak), relationship with treadmill test and 10-km running performance in trained endurance runners

OBJECTIVES: The aim of this study was to determine the peak running velocity on the track field (V(peak_TF)) based on the laboratory treadmill test (V(peak_T)), and relate the V(peak) values as well as their correlation with the 10-km running performance in trained endurance runners. METHOD: Twenty male trained endurance runners (age: 29.5 ± 5.3 years; V̇O(2max): 67.5±17.6 ml · kg(-1)·min(-1)) performed three maximum incremental tests to determine the V(peak): one for V(peak_T) determination and two to obtain V(peak_TF) on the official track field (400 m), and a 10-km running performance. During the incremental tests, maximum heart rate (HR(max)), maximal rating of perceived exertion (RPE(max)), and peak lactate concentration (LA(peak)) were determined. RESULTS: The results showed significant difference between the V(peak_TF) and V(peak_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 RPE(max) determined during the tests. A high correlation was observed between the V(peak) values (r = 0.94), and between V(peak_TF) and V(peak_T) with 10-km running performance (r = -0.95 vs. r = -0.89, respectively). CONCLUSIONS: The good agreement and association with V(peak_T) and high correlation with 10-km running performance demonstrate that the novel track field test is efficient for V(peak_TF) determination.
