Background: The glycemic index (GI) is a system for the classification of carbohydrate-containing foods that is based on their blood-glucose-raising potential. In addition, Carbohydrate ingestion following prolonged strenuous exercise attenuates the suppression of immune system by maintaining plasma glucose concentration and minimizing stress hormone and inflammatory cytokines responses that is the most important factor in reduction of inflammation in paralyzed athletes.
Purpose: The purpose of this study was to determine the effect of pre-exercise high carbohydrate meals with high or low glycemic index on glucose profile pre, immediately post and 1 hour after subsequent endurance exercise.
Method: in a semi-empirical double-blind trial, 12 male athletes was purposefully selected to be titled triable and then divided in 2 groups of high (HGI=94) and low glycemic index (LGI=40), in amount of 1 gram per kilogram of body weight. Afterwards, they performed two 90-min running on a treadmill at 70% VO2max for 2 hours Within 7 days. Blood samples were collected before, immediately after and 1 hour after run for measure of blood glucose concentrations.
