Comportamento glicêmico durante o exercício de resistência: uma revisão sistemática

Abstract

Food consumption of endurance sports practitioners has revealed that many are susceptible to maintaining negative energy intake during training sessions. Consuming adequate amounts of carbohydrates, proteins and fats is important for athletes to optimize their training and performance. In particular, with regard to exercise performance, the need for optimal carbohydrates before, during and after intense sessions with high volume of training and in competitions is evident. The present study aimed to analyze the glycemic impact of different carbohydrate sources in endurance exercises and, consequently, their influence on the athletes' sport performance. Through a systematic review carried out during the months of May and June 2021. The databases Pubmed, Scielo, Lilacs and the Medline portal were used. In the results, 85% of the articles analyzed showed positive effects on the glycemia of athletes with the intake of carbohydrate sources during training and only one of them (15%) showed an insignificant result of the use of carbohydrate for a better performance. It is concluded that carbohydrate is an important macronutrient for the performance of athletes and that its chemical composition and glycemic index are determining factors that influence blood glucose during resistance exercise.
