TI  - Influence of low versus moderate glycemic index of diet on substrate oxidation 
      and energy expenditure during incremental exercise in endurance athletes: a 
      randomized counterbalanced cross-over trial.

AB  - The study was aimed at assessing the influence of 3-week low glycemic index (LGI) 
      versus moderate glycemic index (MGI) diet on substrate oxidation during 
      incremental exercise. 17 runners completed two 3-week trials of either LGI or MGI 
      diet in a randomised counterbalanced manner. Before and after each trial the 
      incremental cycling test was performed. Metabolic alternations were observed only 
      within tested diets and no significant differences in fat and carbohydrate (CHO) 
      oxidation were found between MGI and LGI diets. Following MGI diet CHO oxidation 
      rate increased. The AUC of fat oxidation decreased after both diets. Percent 
      contribution of fat to energy yield declined, whereas contribution of CHO was 
      augmented following MGI diet. This study indicates that the 3-week MGI diet 
      increased the rate of carbohydrate oxidation during incremental cycling test and 
      improved performance in acute intense exercise test, while both high-carbohydrate 
      diets downregulated fat oxidation rate.
