Reliability of Peak Running Velocity Obtained on the Track Field in Runners of Different Performance Levels.

The aim of this study was to verify the reliability of peak running velocity obtained on the track field (V) in runners of different performance levels. 39 male endurance runners were divided into two groups: trained runners (TR; = 22; 10-km time running performance of 35.2 ± 1.

Does Previous Application of Photobiomodulation Using Light-Emitting Diodes at Different Energy Doses Modify the Peak Running Velocity and Physiological Parameters? A Randomized, Crossover, Double-Blind, and Placebo-Controlled Study.

This study aimed to verify the acute effects of photobiomodulation (PBM) using different doses of LED on peak running velocity (V) and physiological parameters. The study had a randomized, crossover, double-blind, and placebo-controlled format, in which 15 physically active males were submitted, besides the control (CON), to four conditions performed 5 min before the maximal incremental treadmill tests for the determination of V: placebo (PLA) and three conditions of PBM application at different doses: PBM applied with 30 J per area (PBM), PBM applied with 120 J per area (PBM), and PBM applied with 180 J per area (PBM). The LED was applied using an equipment with 56 diodes of red light (660 nm; 50 mW/cm and 1.

Effects of Endurance Running Training Associated With Photobiomodulation on 5-Km Performance and Muscle Soreness: A Randomized Placebo-Controlled Trial.

This study aimed to investigate the influence of endurance running training associated with PBM on endurance performance variables and muscle soreness in untrained men. Thirty untrained men were distributed randomly into a placebo (PLA) group and photobiomodulation group (PBMG) and they performed 8 weeks of running training. The PBMG had the PBM performed before all training sessions.

The influence of the regression model and final speed criteria on the reliability of lactate threshold determined by the Dmax method in endurance-trained runners.

Few studies verified the reliability of the lactate threshold determined by Dmax method (LT) in runners and it remains unclear the effect of the regression model and the final speed on the reliability of LT. This study aimed to examine the test-retest reliability of the speed at LT in runners, considering the effects of the regression models (exponential-plus-constant vs third-order polynomial) and final speed criteria (complete vs proportional). Seventeen male, recreational runners performed 2 identical incremental exercise tests, with increments of 1 km·h each for 3 min on treadmill to determine peak treadmill speed (V) and lactate threshold.

Reliability of peak running speeds obtained from different incremental treadmill protocols.

This study compared the values and reliability of peak running speeds from incremental treadmill protocols with different speed increments. Thirty-one men, recreational, endurance-trained runners performed, in an alternate order, three continuous tests with different speed increments (0.5, 1 and 2 km · h(-1)).
