Effects of carbs intake on glycemic response in street runners in the distance of 5 Km
Abstract
Introduction: The aimof the study was to analyze the glycemic responses from twenty subjects through the ingestion of high glycemic index carbohydrates, divided in groups as the following: before the run, fasting, and control. Materials and Method: the first three groups have not eaten for at least 8 hoursbefore the exam. The data was collected by the glucose measurer ACCU-CHEK®Performa, through which individual glycemic values were measured from groups receiving cereal bars and isotonic in six moments (before the test, 15 minutes after ingestion, at 1.5km, 3km and 5km spots and 10 minutes after the test). For the control and fasting groups collections were made at five moments (before the test, at 1.5km, 3km and 5km spots and 10 minutes after the test). Results and Discussion: In groups II and III, in spite of a significant increase after the carbohydrate ingestion, the glycaemia returned to levels similar to those at the beginning maintaining until the end of the session and showing no sharp decrease, which would characterize the hypoglycemic rebound phenomenon. Group I did not show any relevant variation on glycemic levels due to the stock the human body naturally has. Group IV showed a slight decrease on initial parameters. Conclusion: It is possible to conclude, by these results, that inside all the groups, in spite of the long fasting period, none of the subjects studied reached the hypoglycemic state.
