3 ± 18.85 mg/dl
PRE SETS and 95.5 ± 9.51 mg/dl POST SETS p = 0.04), caused by the uptake by the CNS and muscle. There was a significant Bafilomycin A1 mw decrease (only to FG) on lactate concentration comparing PRE SETS to POST SETS (5.2 ± 1.5 mmol/L PRE and 3.7 ± 1.2 mmol/L POST p = 0.03), suggesting again a different glucose sharing between the nervous and muscular systems. Glucose data can be observed on Figure 2. Figure 2 Glucose data (mg/dl) for GSK872 supplier CG and FG for both days. * p < 0.05 comparing FATIGUE to REST within the group on both days. @ p < 0.05 comparing PRE SETS to REST within the group for all groups on both days. # p < 0.05 comparing POST SETS to PRE SETS within the group for all groups on both days. All the metabolic results above can be corroborated by the number of falls observed during the execution of the experimental sets on the balance beam. On WATER DAY the number of falls was statistically higher to FG than CG (5.4 ± 1.14 FG and 3.33 ± 1.37 CG p = 0.02) demonstrating the effect of the fatigue protocol on the concentration status
of the athletes. On CARBOHYDRATE DAY there was no difference in the number of falls between FG and CG (FG 2.29 ± 1.25 and CG 1.88 ± 1.13 p = 0.51). This lack of difference on the number of falls, might be result from the carbohydrate supplementation, which promoted a decrease in the number of falls of the Thymidylate synthase FG even after the athletes did find more the fatigue protocol. We believe that an extra glucose supply is a fast, simple and efficient way to make a difference on muscle and mental performance [25, 26]. Finally, when we compare the two different days, WATER DAY and CARBOHYDRATE DAY, we observed significant differences between the number of falls (WATER DAY CG 3.33 ± 1.37 and CARBOHYDRATE DAY CG 1.88 ± 1.13 p = 0.04) and (WATER DAY FG 5.4 ± 1.14 and CARBOHYDRATE DAY FG 2.29 ± 1.25 p = 0.01)
corroborating once again the idea that the carbohydrate supplementation had a higher effect fueling the central nervous system and maintaining the glucose concentration than only as a fuel for the working muscles, although this demand has also been answered [1, 22, 27]. Number of falls data can be observed on Figure 3. Figure 3 Number of falls for CG and FG on both days. *p < 0.05 compared to CG on WATER DAY. # p < 0.05 compared to FG on WATER DAY. Conclusion We can conclude that fatigue impairs performance in artistic gymnastic athletes due to mental fatigue and consequent loss of concentration that leads to mistakes in the exercise execution. We could also conclude that carbohydrate supplementation was able to restore the concentration levels of the athletes as well as to supply energy to the muscles, reducing mistakes or the number of falls on the balance beam, even after an exhaustive training session.
