摘要：Avila BJ, Brown LE, Coburn JW, Statler TA. Effects of Imagery on Force Production and Jump Performance. JEPonline 2015;18 (4):42- 48. The purpose of this study was to examine the effects of functionally equivalent imagery on absolute and explosive force production. Twenty five male subjects were asked to make three visits to the lab. The first visit consisted of familiarization with the equipment and procedures. During the following two visits, the subjects completed a countermovement jump (CMJ) and a mid-thigh isometricpull under control or experimental conditions. For the experimental condition, the subjects listened to a 30-sec specific imagery script immediately preceding the tasks. For the control condition, the subjects read a passage on the sliding filament theory for 30 sec immediately preceding the tasks. Results demonstrated that ground reaction force in the isometric-pull was significantly greater than the control, but there was no significant difference in the CMJ performance. The isometric-pull was a novel task for most subjects. Therefore, imagery may have allowed subjects to rehearse and become familiar with the new movement as well as increased motivation and confidence.
