Abstract
The present randomized study investigated the effect of acute supplementation of 800 mg/kg of ketone monoester ingestion (KE) or placebo (PL) and 210 mg/kg of NaHCO3 co-ingestion on cycling performance of WorldTour cyclists during a road cycling stage simulation. Twenty-eight cyclists participated in the study (27.46±4.32 years; 1.80±0.06 m; 69.74±6.36 kg). Performance, physiological, biochemical, and metabolism outcomes, gut discomfort, and effort perceived were assessed during a road cycling simulation composed of an 8-min time-trial (TT) performance + 30-s TT + 4.5 hr of outdoor cycling + a second 8-min TT + a second 30-s TT. Greater absolute and relative mean power during the first 8-min TT (F = 5.067, p = .033,ηp2=.163, F = 5.339, p = .029,ηp2=.170, respectively) was observed after KE than after PL (KE: 389±34, PL: 378±44 W, p = .002, d = 0.294 and KE: 5.60±0.42, PL: 5.41±0.44 W/kg, p = .001, d = 0.442). Additionally, greater concentration ofβ-hydroxybutyrate blood concentration (F = 42.195, p
