本研究旨在探討高運動技能者社會體型焦慮與運動參與之關係。受試對象共計365人，其中包括有運動訓練經驗者191人及無運動訓練經驗者174人。所有受試者均填寫社會體型焦慮量表及運動自我效能量表。運動參與的測量則是透過受試者自陳的方式，以自覺的運動強度、運動時間及運動頻率三者的乘積來表示。研究結果：在控制性別變項後，無運動訓練經驗者的運動自我效能及社會體型焦慮均與運動參與呈現顯著負相關；但對於有運動訓練經驗者而言，此關係並未達到統計的顯著水準。本研究結論：高運動技能者的社會體型焦慮與運動參與無顯著線性關係，可能是表現高運動技能的優勢抵消了個體所知覺的社會體型焦慮。

We determined the relationship between physical self-perception and sport participation in a cohort with good sport skill. 365 participants, including 191 subjects with>4 years training experiences on various types of sport and 174 subjects without sport training experience, completed Social Physique Anxiety (SPA) Scale and Self-Efficacy for Physical Activity Scale. Sport participation outside office hour, indicated by the product of perceived intensity, duration, and frequency, was self-reported by all subjects. Both self-efficacy levels in participating sport activity and SPA levels were negatively correlated with sport participation for the subjects without sport training experience after controlled for gender. However, this relationship vanished when the subjects confined to the subjects with sport training experience. The novel finding of the study is that linear relationship between SPA and sport participation diminished in cohort with good sport skill, suggesting a value of sport skill acquisition for counterbalancing SPA.
