Carbohydrate Management in Athletes with Type 1 Diabetes in a 10 km Run Competition

Abstract The aim of this study was to identify the real consumption of CHO during a 10 km competitive run, to compare data with the recommended quantities according to current guidelines, and to analyse the clinical events associated with these different amounts. Protocol 1: observational study including 31 athletes with T1D and 127 athletes without diabetes, comparing data taken from dietary records of CHO intake on the competition day. Protocol 2: single-blind randomized trial in 18 athletes with T1D, testing a pre-exercise CHO supplement of 0.7 g CHO·kg − 1 (n=10) or 0.35 g CHO·kg − 1 (n=8). The results showed that T1D athletes consumed a lower quantity of CHO than athletes without diabetes at their usual breakfast and during the meal taken
