Muscle glycogen concentration following the 16 day dietary intervention and exercise trial day, which consisted of a resting (rest) muscle biopsy, another following 60 min cycling at 70% VO
time to fatigue at 90% VO
(90%) and at the end of 6 h recovery (6 h recovery). Carbohydrate (CHO) and carbohydrate and whey protein isolates (CHO + WPI) trial were similar at rest. All time points following exercise were lower than rest in both trials (# P < 0.05). CHO + WPI trial was increased from 90% VO2 max to end of 6 h recovery (* P < 0.05). Values are means ± SEM (n = 6).
