This study aimed to clarify whether the add-on placebo effect can augment the psychological and physiological benefits of exercise. The inclusion criteria were met by 18 studies with 1,221 participants. The add-on placebo effects promoted a more positive affect (g = 0.430), greater self-esteem (g = 0.454), improved cardiorespiratory fitness (g = 0.273), and decreased perceived exertion (g = 0.476) and blood pressure (g = 0.268). Improved affect benefits were moderated by placebo type (elaboration > external medium), self-selected exercise intensity (no > yes), and exercise type (running > nonspecific). The results support the proposal that the add-on placebo effect can provide significant positive benefits for exercisers, particularly in terms of psychological responses.
本研究旨在阐明附加安慰剂效应是否能增强运动对心理和生理的益处。18项研究共1221名参与者符合纳入标准。附加安慰剂效应促进了更积极的情绪（g = 0.430）、更强的自尊（g = 0.454）、改善了心肺功能（g = 0.273），并降低了主观用力感觉（g = 0.476）和血压（g = 0.268）。安慰剂类型（阐述性>外部媒介）、自我选择的运动强度（否>是）和运动类型（跑步>非特定运动）对情绪改善有调节作用。结果支持了附加安慰剂效应能为运动者带来显著积极益处的观点，特别是在心理反应方面。
