—(a) Power output, (b) heart rate, and (c) glucose determined from continuous glucose monitoring during the 20-min time trial after ingestion of 0.35 g/kg KE (gray circles) or a ketone-free PL (open circles). Data are presented as mean ± SD (n = 23 for power output and heart rate and n = 19 for glucose). *p < .05 main effect condition (KE vs. PL) from exploratory two-way repeated-measures analysis of variance. KE = ketone monoester; PL = placebo.
