Table 5: Performance in the cycling sector. Figure 3: Evolution of blood glucose during tests 1 and 2. The glucose concentrations after supplementation appear in shading. PG: placebo group; SG: supplemented group. Figure 4 shows the weight of the athletes at the baseline assessment (familiarisation) before starting the carbohydrate loading for test 1, as well as in both tests. Although there is a positive trend in the weights, no significant differences were observed. \begin{table}
