Many adults worldwide do not meet current physical activity (PA) guidelines. Mental fatigue decreases the likelihood of choosing to engage in PA. Message framing may enhance PA motivation when fatigued. We examined the effects of mental fatigue and message framing on PA motivation with additional focus on the messaging "congruency effect." Three hundred and twenty undergraduates completed measures of dispositional motivational orientation and were exposed to either gain-framed or loss-framed messages before completing an effort discounting questionnaire. Results showed lower motivation to engage in PA of higher intensities and longer durations. Direct effects of message framing on PA motivation were not significant. Interaction effects revealed that participants receiving messages congruent with their dominant motivational orientation showed increased motivation for light-intensity PA and decreased motivation for vigorous-intensity PA as mental fatigue increased. Findings suggest that providing messages congruent with one's dominant motivational orientation may increase motivation for engaging in light-intensity PA when fatigued.

消息中有什么？精神疲劳和信息框架对体育活动动机的影响。


全世界许多成年人不符合当前的体育活动 （PA） 指南。精神疲劳会降低选择参与 PA 的可能性。疲劳时，信息框架可能会增强 PA 的积极性。我们检查了精神疲劳和信息框架对 PA 动机的影响，并特别关注信息传递“一致性效应”。320 名本科生完成了性格动机取向的测量，并在完成努力折扣问卷之前接触到了收益框架或损失框架的信息。结果显示，参与更高强度和更长持续时间的 PA 的动机较低。信息框架对 PA 动机的直接影响不显著。交互效应显示，随着精神疲劳的增加，接收与其主要动机取向一致的信息的参与者表现出对光强度 PA 的动机增加，而对强度 PA 的动机降低。研究结果表明，提供与一个人的主要动机取向一致的信息可能会增加疲劳时进行光强度 PA 的动力。
