Abstract Purpose The main aim of the present study was to verify which variable, between peak running velocity (Vpeak) and the velocity at lactate threshold (vLT), better correlates with 10-km running performance. The second aim was to demonstrate the association between these two variables (Vpeak and vLT). Methods Seventeen male, recreational, endurance-trained runners perfomed three tests: incremental exercise test to determine Vpeak and other for vLT determination by maximal deviation method (Dmax), and 10-km running performance. Incremental tests were performed on the treadmill and the 10-km running test on the outdoor track. Incremental tests started with a velocity of 8 km·h−1, which increased by 1 km·h−1 between each successive 3-min stage until exhaustion. For vLT determination it was required pauses for blood samples collection. Results It was found that both Vpeak and vLT were highly correlated with 10-km mean velocity (MV10-km) (r = 0.92 and 0.81, respectively). It was found a high association between Vpeak and vLT (r = 0.91). Conclusion Both Vpeak and vLT were highly associated with M V10-km, in which V peak better correlates with performance. In addition, V peak and vLT were highly related to each other. In practical application, coaches and runners should use both Vpeak and vLT as parameters to prescribe and monitor running training to provide valuable information on the progress of training and its control.

Introduction During endurance running performance (e.g., 5-km, 10-km, 42-km) the main responsible for energy production is the oxidative system [1]. Among the variables determined during incremental running tests and that influence the endurance performance, the peak running velocity (Vpeak) and velocity at lactate threshold (vLT) are important indexes used for training prescription [2–4]. The V peak is defined as the highest velocity attained during a maximal incremental * Cecília Segabinazi Peserico [email protected] 1

test without the use of metabolic equipment or invasive techniques [5, 6], while vLT is a submaximal intensity that represents the individual aerobic capacity and is determined with incremental protocols with pauses between stages for blood samples collection [7]. Both Vpeak [5, 6, 8–10] and vLT [2, 4, 11] are associated predictors of endu
