RESUMO:
Introduction: The determinants of physical performance are largely explained in terms of biomechanical or metabolic capacity. In the last decade a range of studies has showed that brain and cognitive mechanisms may be related to better performance in endurance athletes. However, questions remain about how much cognitive factors may be related to the performance of athletes in exercises that seem to represent a test situation. Objective: to evaluate the correlation between inhibitory control and endurance performance of recreational cyclists in the time-trial. Methods: 15 male recreational cyclists (274.7 ± 49.5, peak power output, 29.80 ± 5.3, 75.27 ± 8.4 kg, 1.75 ± 0.1 m, 24.50 ± 2.2, kg.m², 23.21 ± 4.8% fat) participated in the study. The subjects attended two sessions, the first one was aimed at screening, familiarization with the perceptual scales, stroop test for inhibitory control evaluation and maximal incremental test on cycle ergometer, starting at 100W and increasing 30W until voluntary exhaustion. In the second session the volunteers performed the 10 km time-trial, in which they were free to regulate the march and were directed to finish in the best time. In both efforts the subjective perception of effort, affection, associative or dissociative thinking and heart rate were computed, being in intervals of 2 min for the incremental test and every 2 km for the time-trial. The Shapiro-Wilk test was used to verify the normality. Pearson's correlation coefficients were used to analyze the degree of correlation between performance in the stroop test and endurance performance in the incremental and time-trial test. Level of statistical significance adopted was p <0.05. Results: Pearson’s correlations revealed a negative association (r = -0.78; p = 0.001) between peak power (Wpeak) and time in the time-trial test. In addition, the subjects with the shortest reaction time (TR) had greater Wpeak in the incremental test (r = -0.59; p = 0.02) and a better time-trial performance (r = 0.56; p = 0.02). Conclusion: The best inhibitory control, verified through the TR in the stroop test, seems to be associated with a better performance of recreational cyclists in the 10 km time-trial.
