- Consumption of cocoa-enriched dark chocolate (DC) has been shown to alter glucose and insulin concentration during rest and exercise compared with cocoa-depleted control (CON). However, the impact of DC consumption on exercise metabolism and performance is uncertain. Therefore, we investigated carbohydrate metabolism via stable isotope tracer techniques during exercise after subjects ingested either DC or CON. Sixteen overnight-fasted male cyclists performed a single-blinded, randomized, crossover design trial, after consuming either DC or CON at 2 h prior to 2.5 h of steady-state (SS) exercise (similar to 45% peak oxygen uptake). This was followed by an similar to 15-min time-trial (TT) and 60 min of recovery. [6,6-H-2(2)] Glucose and [U-C-13]glucose were infused during SS to assess glucose rate of appearance (R-a) and disappearance (R-d). After DC consumption, plasma (-)-glucose and insulin concentrations were significantly (p
