本研究的主要目是探討高中女子籃球隊使用6號比賽球，是否會影響球隊的進攻表現。以參加92至94學年度高中女子籃球聯賽隊伍為研究對象，其中92學年度使用七號球，93及94學年度使用六號球。以獨立樣本單因子變異數分析進行92、93及94學年度球隊進攻技術表現的差異，若各年度間球隊的技術表現有差異者，則以薛費氏法進行事後比較。結果顯示：三分球總投籃次數、三分球投籃不中的次數，93學年度明顯多於92學年度和94學年度(M:93>94>92)，二分球的投籃命中數、二分球總投籃次數和助攻次數92學年度和94學年度多於93學年度(M:94>92>93)，94學年度的失誤次數和進攻次數顯著多於92學年度(M:94>93>92)。結論：高中女子球隊使用六號球後在整個比賽節奏（進攻次數增多）顯著加快，在三分區域內的投籃及失誤次數顯著多於使用7號球，而兩分區域內的投籃和助攻次數則從93學年度到94學年度由減少轉為增加。顯示高中女子球隊在使用六號球後，由於進攻技術的改變，將會影響球隊的訓練方式。

The purpose of this study was to research the effects of offensive performances after using number 6 official basketball in high school female basketball teams. Samples consist of female teams that attended the High School Basketball League from 92 to 94 year. The research used One-way ANOVA to explain the differences that occurred in the offensive performances. If there was any significant difference that results, then multiple comparison analytic method (Scheffe's multiple comparison) should be applied. The result indicated that: The 93 year was significantly higher in 3 point attempts and 3 point loses than the 92 and 94 year (M:93>94>92). The 92 and 94 year were significantly higher in 2 point made, 2 point attempts and assists than the 93 year (M:94>92>93). The 94 year was significantly higher in turnovers and offensive times than the 92 year (M:94>93>92). In conclusion, after using number 6 official basketball, the high school female teams obviously increased in competitive speed (offensive times), turnovers, and 3 point attempts than using the number 7 official basketball. However, assists and 2 point attempts increased from 93 year to 94 year. This study indicated that the high school female basketball teams had more difference in skill performances after using the number 6 official basketball, and this difference affected the teams' training methods.
