本研究的主要目的在探討不同網球發球方向(相容性)及不同發球前期對接
發球者整體反應時間、反應時間與動作時間的影響。本研究的受試者為國
立臺灣師範大學體育系修習過網球課之慣用右手者男生50名，分別觀看由
一位甲組球員發網球的錄影帶，此影片係經專業人士處理後使畫面形成五
種不同的發球前期畫面及兩種不同的發球方向，每種發球方向及發球前期
各出現5 次的發球動作，因此所有的受試者共觀看50個發球畫面。受試者
在觀看每個發球畫面後，需先判斷發球方向後再往發球方向移動並按鍵，
以測試受試者的RT與MT。將所得資料分別以二因子重複量數變異數分析及
杜凱氏HSD 法事後比較進行統計分析，以驗證假設。經研究結果討論後，
得到如下的結論：一、在整體反應時間 (TRT)上，不同的網球發球方向與
不同的發球前期間有交互作用的關係存在。在不同的發球方向上，受試者
面對發向右邊時的 TRT比發向左邊時的 TRT快；在不同的前期上，受試者
在較適中的前期長度(2.5～5秒) 能產生較快的 TRT，但在較短的前
期(1.5秒)和較長的前期(8秒) 則產生較慢的 TRT。二、在反應時間(RT)
上，不同的網球發球方向與不同的發球前期間無交互作用的關係存在，且
受試者面對不同發球方向時的RT亦沒有顯著不同；但在不同的發球前期上
，受試者在較適中的前期長度(2.5～5秒)能產生較快的RT，但在較短的前
期(1.5秒)和較長的前期(8秒)則產生較慢的RT。三、在動作時間(MT)上，
不同的網球發球方向與不同的發球前期間有交互作用的關係存在。在不同
的發球方向上，受試者面對發向右邊時的MT比發向左邊時的MT快；在不同
的前期上，MT受前期的影響較小，僅在發球方向是左邊時，於前期1.5秒
與2秒時的MT比前期8秒時的MT快。

The purpose of this study was to investigate the effects of
variable foreperiods and compatibility of tennis serve on total
response time(TRT),reaction time(RT) and movement time(MT).Forty
right-handed males of National Taiwan Normal University in the
Department of Physical Education were studied.Each subject
separately watched the film in which one senior-level tennis
player was serving a ball.This film had been processed by a
professional person into tennis services of 5 variable
foreperiods,2 different orientations and had totally 50 pictures
for serving a ball.After watching a designated picture for
serving a ball,the subject had to decide whether the ball would
be served to the left or right side.Upon deciging,the subject
would press a button indicating which side the ball would be
served to.By doing this,we could measure theirRT and MT which
should be analyzed separately by the two-way ANOVA and Tukey
methtod.As the result of this study the following conclusions
were reached: 1.In the TRT circumstance there were
mutual functions in tennis service between different
orientations and variable foreperiods.In the different
orientations,the right side was significantly faster than the
left on TRT.In variable foreperiods,the foreperiods of 2.5-5sec.
was a significantly faster than 1.5 sec. and 8 sec. on TRT. 2.In
the RT circumstance there were not mutual functions in tennis
service between different orientations and variable foreperiods.
Furthermore there was not significant different orientations of
both the right and left sides.In variable foreperiods,the
foreperiods of 2.5-5sec. was a significantly faster than 1.5
sec. and 8 sec. on RT. 3.In the MT circumstance there were
mutual functions in tennis service between
differentorientations and variable foreperiods.In the different
orientations,the right side was significantly faster than the
left on MT.In variable foreperiods,the effects had no
significant difference on MT,only serving a ball in the
direction of the left,the foreperiods of 1.5sec. and 2 sec. was
a significantly faster than 8 sec. on MT.
