TL;DR: In this paper, the timing of mentally executed movements was measured in ten patients with hemiplegia, tetraplegia, and paraplegia and they reported a sensation of subjective effort accompanying the execution of the mental tasks.
Abstract: The timing of mentally executed movements was measured in ten patients with hemiplegia, tetraplegia and paraplegia. In hemiplegic patients a significant difference in mental duration times was found between the paralysed and the normal “represented limb”. The paralysed limb was mentally much slower than the healthy one. In contrast, movement times in tetraplegic and paraplegic patients did not differ from those in normal subjects. All patients reported a sensation of subjective effort accompanying the execution of the mental tasks. These observations are compatible with an outflow processing underlying motor imagery.

TL;DR: In this paper, the authors trace the development of the field of imagery, synthesize theories explaining how it affects performance, and then relate how it may best be used today in applied sport psychology.
Abstract: The subject of imagery is receiving a great deal of attention in applied sport psychology. The purpose of this overview is to trace the development of the field of imagery, synthesize theories explaining how it affects performance, and then relate how it may best be used today. In the first section imagery is defined and the history of its use discussed, followed by explanations for how imagery affects physical and psychological skills. The use of imagery in sport is then described, and the scientific literature pertaining to the effectiveness of imagery in developing physical and psychological skills is examined.
