Regular endurance training does not influence the glycemic index determination in women.

Objective: This study investigated the influence of regular endurance training on the glycemic index (GI) of a breakfast cereal in women as previous results from men indicate that endurance training may influence the GI.

Methods: Subjects were 17 sedentary (SE) and 19 endurance trained (ET) healthy, young, adult women of normal body mass index. All subjects performed two tests with the reference food glucose and two tests with a breakfast cereal in a randomized order.
