Wagenmakers, A. J., Jeukendrup, A. E., & Saris, W. H. (1996). Carbohydrate feedings improve 1 h time trial cycling performance. Medicine and Science in Exercise and Sports, 28(5), Supplement abstract 221.

Carbohydrate (CHO) feedings have been shown to improve endurance performance at moderate intensities (60-70% VO2max) and of more than two hours duration. This study found that ingesting CHO at a rate of 1 gm/min during exercise, improved performance in a cycling task of approximately one hour duration.

Implication. CHO feeding during exercise improves performance when the task duration is of one hour or longer.
