运动想象持续时间与实际运动动作持续时间密切相关。在2个实验中，作者研究了在3周的训练期间改变心肌梗死速度对实际运动持续时间的影响。实验一涉及两个系列的身体动作，24名参与者在心理上比他们的实际执行速度快或慢。快速MI组的实际时间在随后的表现中有所减少。实验2的参与者是21名熟练的运动员，他们在慢（快）速心肌训练后增加（减少）了他们精心排练的实际动作时间。然而，这种影响与任务相关：心肌梗死只影响自我发起的运动。MI对实际速度执行的影响支持意念运动理论，因为对动作的感觉结果的预期是心理表征的。
Researchers realize that motor imagery (MI) duration is closely linked to actual motor action duration. In 2 experiments, the authors investigated the effect of changing MI speed on actual movement duration over a 3-week training period. Experiment I involved 2 series of body movements that 24 participants mentally performed faster or slower than their actual execution speeds. The fast MI group's actual times decreased on subsequent performance. Participants in Experiment 2 were 21 skilled athletes who increased (decreased) their well-rehearsed actual movement times after MI training at a slow (fast) speed. The effect was task-related, however: MI affected only self-initiated movement. The effect of MI on actual speed execution supports the ideomotor theory because anticipation of sensory consequences of actions is mentally represented.
