Abstract：The effectiveness of motor imagery practice as an important training technique for the acquisition of sports skills and the enhancement of sports performance has been validated and supported in numerous studies. However, physical education (P.E.) instruction in Taiwan has focused almost exclusively on purely physical exercise; very few P.E. teachers in Taiwan incorporate imagery practice into their pedagogy. The effectiveness of yoga in improving physical and psychological health, in relieving stress, and in other areas is also well-established in relevant literature. The purpose of this study is to foster the use of motor imagery practice in yoga instruction by describing the relevant the theoretical development, offering key theoretical viewpoints and teaching objectives, and illustrating benefits derived from the application of motor imagery practice. This article further describes various elements of the PETTLEP (physical, environment, task, time, learning, emotion, perspective) model, which enables learners to cultivate capabilities such as motion recognition and self-awareness during yoga exercise. Suggestions for future research into the practical applications of the PETTLEP model are also provided. (Full text)
