Endurance physical exercise is accompanied by subjective perceptions of exertion (reported perceived exertion, RPE), emotional valence, and arousal. These constructs have been hypothesized to serve as the basis for the exerciser to make decisions regarding when to stop, how to regulate pace, and whether or not to exercise again. In dual physical-cognitive tasks, the mental (executive) workload generated by the cognitive task has been shown to influence these perceptions, in ways that could also influence exercise-related decisions. In the present work, we intend to replicate and extend previous findings that manipulating the amount of executive load imposed by a mental task, performed concomitantly with a submaximal cycling session, influenced emotional states but not perceived exertion. Participants (experienced triathletes) were asked to perform a submaximal cycling task in two conditions with different executive demands (a two-back version of the n-back task vs. oddball) but equated in external physical load. Results showed that the higher executive load condition elicited more arousal and less positive valence than the lower load condition. However, both conditions did not differ in RPE. This experimental dissociation suggests that perceived exertion and its emotional correlates are not interchangeable, which opens the possibility that they could play different roles in exercise-related decision-making.

次最大循环过程中执行负荷对感知的运动和情绪价的可分解影响。

耐力体育锻炼伴随着对运动的主观感知（报告的感知运动，RPE），情绪价和唤醒。假设这些构造可作为锻炼者做出决定的基础，包括何时停止，如何调节步伐以及是否再次锻炼。在双重身体认知任务中，认知任务产生的精神（执行）工作量已显示出可以影响这些感知的方式，也可能影响与运动有关的决策。在目前的工作中，我们打算复制和扩展以前的发现，这些发现操纵精神任务施加的执行负荷，伴随次最大循环的运动而执行，影响情绪状态但不感知劳累。参与者（有经验的铁人三项运动员）被要求在两种具有不同执行要求的条件下执行次最大骑自行车任务（n背任务与奇球的两个后背版本），但在外部身体负荷上相等。结果表明，较高的执行负荷条件比较低的负荷条件引起更多的唤醒和较小的正价。但是，这两个条件在RPE中没有区别。这种实验性的解离表明，感知的运动及其情感联系是不可互换的，这打开了它们在与运动有关的决策中可能扮演不同角色的可能性。结果表明，较高的执行负荷条件比较低的负荷条件引起更多的唤醒和较少的正价。但是，这两个条件在RPE中没有区别。这种实验性的解离表明，感知的运动及其情感联系是不可互换的，这打开了它们在与运动有关的决策中可能扮演不同角色的可能性。结果表明，较高的执行负荷条件比较低的负荷条件引起更多的唤醒和较少的正价。但是，这两个条件在RPE中没有区别。这种实验性的解离表明，感知的运动及其情感联系是不可互换的，这打开了它们在与运动有关的决策中可能扮演不同角色的可能性。
