身體是用來辨識運動員與一般人的特徵，即使在運動員身上，因為運動項目的不同對於身體能力的需求亦有所差異。在網球的領域裏，身體能力代表了個人的技術風格與層級。運動員技術學習過程中是經由身體感官來體會，進而建立起技術的認知體系。本研究透過參與觀察與訪談解析網球員的身體感，並究明網球員身體感與技術階序的關係，以身體感（bodily senses）的研究概念，來涵括身體、球、球拍的遭逢過程。研究發現網球員的養成是思考與身體主體性互為建構的歷程，透過時間的積累逐漸將打網球的知識內化於身體中。網球員打球常迴盪於鬆與緊、流暢與不流暢、安全與不安全、熟悉與陌生的身體感中。此外，球感包含著對球的時間感、空間感與接觸感，它在球員的階序性高低扮演關鍵性角色。

Body is a characteristic which differentiates athletes and normal people. Even on athletes, the needs of body abilities are different because of different sports items. In tennis, body abilities stand for personal technique styles and levels. During the process of learning tennis techniques, tennis techniques are formed by not only thinking which leads body to learn techniques but also body's initiatives which produce body experiences. The purpose of this study is using participant observation and interview to explore tennis players' bodily senses in the process of their learning techniques. Besides, the study tries to analyze how bodies join techniques learning initiatively and build tennis players' bodily senses system. Research discovered that the cultivation of a tennis player is a process of mutual construction between mind and the subjectivity of the body. Tennis players had bodily senses of loose and tight, smooth and not smooth, safe and unsafe, familiar and unfamiliar, when playing tennis. In addition, ball senses include feeling of time, space, contact. Beside the basic vertical relation between age and grade, the subjectivity of the body: ball senses is the major factor of the status in teams.
