abstract = {To test the hypothesis that cognitive load (low vs. high load) during a 20 min self-paced
cycling exercise affects physical performance. Bayes analyses revealed extreme evidence for the 2-back task being more demanding than
the 1-back task, both in terms of accuracy (BF10 = 4490) and reaction time (BF = 1316). The
data only showed anecdotal evidence for the alternative hypothesis for the power output
(BF10 = 1.52), moderate evidence for the null hypothesis for the heart rate (BF10 = 0.172),
anecdotal evidence for RPE (BF10 = 0.72) and anecdotal evidence for mental fatigue (BF10 =
0.588). Our data seem to challenge the idea that self-paced exercise is regulated by top-down processing,
given that we did not show clear evidence of exercise impairment (at the physical,
physiological and subjective levels) in the high cognitive load condition task with respect to
the low working memory load condition. The involvement of top-down processing in selfpacing
the physical effort, however, cannot be totally discarded. Factors like the duration of
the physical and cognitive tasks, the potential influence of dual-tasking, and the participants’
level of expertise, should be taken into account in future attempts to investigate the role of
top-down processing in self-paced exercise.},
