Test-Retest Reliability of Running Economy and Other Physiological Parameters During 90 min of Running in Well-Trained Male Endurance Runners.

ABSTRACT: Running economy (RE) is highly reliable when measured in an unfatigued state; however, its reproducibility during prolonged exercise has not been investigated. RE is known to worsen during prolonged exercise (referred to as RE "durability"), and quantifying the reliability of RE durability measurements will determine our sensitivity to detect subtle differences between groups or conditions. This study aimed to assess the reliability of RE and other physiological parameters throughout a 90-min run in the heavy-intensity domain among well-trained runners. Fourteen male marathon runners (maximal oxygen uptake (V̇O_2max): 63.1 ± 5.8 mL·kg^-1·min^-1; marathon time: 02:47 ± 00:10 h:min) completed two 90 min treadmill runs at a speed of 10% Δ between lactate threshol
