目的：本研究主在探討我國大專優秀男子排球隊教練在不同替補球員類型與不同替補時機之應用情形，並針對常用之替補時機加以探析其不同替補類型之應用情形。方法：本研究以98學年度大專排球運動聯賽男子組公開一級1-6名複決賽，前6名隊伍於比賽中各項球員替補類型與替補時機之應用情形作爲本研究之對象，將記錄資料以敘述性統計及單因子變異數分析法進行檢定。結果：替補發球與替補防守等類型的應用顯著多於替補攻擊與舉球；在小幅落後（落後5分內）與小幅領先（領先5分內）時，應用替補之情形明顯多於其他替補時機；在小幅領先時，替補發球類型的應用情形明顯多於替補攻擊與替補舉球，在小幅落後時，替補發球與替補防守等類型的應用情形明顯多於替補攻擊與替補舉球。結論：大專優秀男子排球隊教練於比賽中，以替補發球與替補防守作爲較常應用之替補類型考量，其中當球隊處於小幅落後及小幅領先時，亦是較常運用的替補時機考量。當球隊處於小幅落後之時，可考量運用接發球或防守較佳之球員替補上場，搭配場上之自由球員，共同補強隊中之防守，藉以將比分拉近甚至超前。
