Distracting Attentional Focus from Fatigues Does Task Complexity Make a Difference

Abstract

This study examined how exercise endurance was influenced by varying the task complexity of dissociative coping. In Trial 1, 60 subjects were randomly assigned to one of three conditions: a simple cognitive task (SCT), a complex cognitive task (CCT), or a control group (CG). All subjects were instructed to maintain an isometric contraction of 40% maximum on a handgrip dynamometer for as long as possible. Results revealed that subjects in the SCT and CCT conditions had greater endurance than those in the CG; however, varying the complexity of the task made no difference. Trial 2, a within-subjects design, was implemented to examine the potential mediating effects of task preference on cognitive coping. The protocol was identical to Trial 1 except that subjects previously assigned to the SCT condition were given the CCT and vice versa. Upon completion of Trial 2, subjects were asked which coping style they had preferred. A two-way mixed ANO-VA resulted in a significant coping style X preference interaction ...
