Effects of pacing strategy on metabolic responses to 2-min intense exercise in Thoroughbred horses.

ABSTRACT: Evidence suggests that positive pacing strategy improves exercise performance and fatigue tolerance in athletic events lasting 1-5 min. This study investigated muscle metabolic responses to positive and negative pacing strategies in Thoroughbred horses. Eight Thoroughbred horses performed 2 min treadmill running using positive (1 min at 110% maximal O₂ uptake [V̇O₂max], followed by 1 min at 90% V̇O₂max) and negative (1 min at 90% V̇O₂max, followed by 1 min at 110% V̇O₂max) pacing strategies. The arterial-mixed venous O₂ difference did not significantly differ between the two strategies. Plasma lactate levels increased toward 2 min, with significantly higher concentrations during positive pacing than during negative pacing. M
