Resumen
The determinants of physical performance are widely studied in terms of peripheral
energy production capacity. In the past decade, many studies have suggested the
effect of cognitive mechanisms on performance regulation. However, questions about
the role of cognitive function in different forms of athletic performance still remain
open in the literature, particularly in test simulation. The aim of this study was to
verify the relationship between inhibitory cognitive control and cyclist’s performance
in the 10km time trial test (TT). Seventeen male recreational cyclists (278.85 ± 48.9,
peak power; 30.35 ± 5.6, years; 76.28 ± 8.6 kg; 1.76 ± 0.1 m; 22.60 ± 6.8% fat)
participated in the study. Participants held two sessions. The first was intended to
perform the cognitive inhibitory control (IC) (stroop task) and maximum incremental
test on a cycle ergometer. In the second session, the volunteers performed the 10
km TT test. The subjective perception exertion, attentional focus (associative or
dissociative thinking) and heart rate were reported during exercise sessions.
Pearson's correlation coefficients were adopted to analyze the degree of correlation
between the IC, peak power (WPEAK) and time in the TT. Level of statistical
significance adopted was p <0.05. There was a significant correlation between the
reaction time (RT) in the stroop task and performance in the TT (r = 0.54; p = 0.02).
WPEAK was inversely correlated (r = - 0.78; p = 0.001) with time in the TT test.
Additionally, there was positive correlation (r = 0.52) between the time in the TT and
the mean value of the attentional focus (p <0.05). Our study demonstrated that better
IC contributed to improve performance in the incremental and time trial test, in
addition, greater dissociative attentional focus to exercise contributed to better
performance in the time trial test.
