羽球運動不論是單打或雙打，專項體能是影響選手成績表現的因素之一，而體脂肪百分比的高低，是否亦會影響專項體能的表現，身為教練者有瞭解之必要性。本研究的目的旨在探討大專男子羽球選手體脂肪百分比與專項體能的相互關係，且就單打與雙打之不同項目間比較體脂肪百分比及專項體能的差異。以國立體育學院男子羽球選手為對象，依參與組別分別測得男子單打八名與雙打九名，以計十七名。本研究採用我國優秀運動員體脂肪百分比測量方法及七項專項體能測驗，經統計分析獲得以下結論：男子單打與男子雙打兩組之間，除了立定跳遠測量變項鞏有顯著差異存在，顯示單打選手在立定跳遠能力稍高於雙打選手，其餘各項無明顯差異。單打組方面體脂肪百分比對各專項體能並無關係存在，在雙打組方面體脂肪百分比與十二分鐘跑有顯著相關存在（r=.754）。而在全體組方面，體脂肪百分比與立定跳遠變有顯著相關存在（r=.607）。

Specific physical fitness is an important factor affecting the performance in badminton. And it is critical for coaches to know whether body fat determines the specific physical fitness. The purpose of the study was to investigate the relationship between body fat and specific physical fitness in badminton, and to compare the differences of body fat and specific physical fitness in badminton, and to compare the differences of body fat and specific physical fitness between single and double plays. 17 male badminton athletes from National College of Physical Education and Sports were served as subjects, and divided into single group (8 persons) or double group (9 persons). Body fat percentage measurement and seven specific physical fitness testing were involved in the study. Collected data were analyzed through SPSS 10.0 for windows statistic software. In conclusion, the study indicated that except standing long jump(p<.05), there was no significant difference between single group and double group. It implied that the single group, the correlation of body fat and specific physical fitness was not significant. Third, in the double group, the correlation of body fat and twelve minutes running were significant (r=.754). Last, the correlation between body fat and standing long jump was significant for each subject.
