Abstract:

Individuals’ emotional experiences during or after exercise directly affect the likelihood of future exercise repetition. The placebo effect can enhance the emotional benefits of exercise through the psychological mechanism of outcome expectation. Outcome expectation can be divided into induced expectation and habitual expectation. This study recruited 70 university students to participate in an outcome expectation intervention and examined the effects of eight weeks of induced expectation on exercise-related emotional benefits. The results showed that: 1) Outcome expectation produced a placebo effect on the emotional benefits of exercise. 2) Habitual expectation moderated the effect of induced expectation on exercise-related emotional benefits. This study demonstrates the effectiveness of induced expectation as a placebo intervention strategy and provides theoretical support for promoting sustained public participation in physical exercise and for enhancing the emotional “added value” gained through exercise.

Key words: outcome expectation, induced expectation, habitual expectation, placebo effect, emotional benefits of exercise

摘要：

个体在运动中或运动后的情绪体验直接影响到未来重复运动的可能性，安慰剂效应可以增加参与者的运动情绪效益，其心理机制是结果预期，可分为诱发预期和习惯性预期。研究选取70名大学生进行结果预期干预，探讨8周诱发预期对运动情绪效益的影响。结果发现：(1)结果预期对运动情绪效益产生安慰剂效应；(2)习惯性预期在诱发预期影响运动情绪效益中存在调节效应。研究揭示了以诱发预期作为安慰剂干预手段的有效性，为推动大众参与并坚持锻炼，促进其在运动中获得“好上加好”的情绪效益提供了实证支持。
