本研究目的在探討不同訓練法對國中生網球選手基本及專項體能效果之影響。本研究將15名國中男子網球選手（平均年齡為14.27±0.88歲，平均身高為166.2±9.38公分，平均體重為57.4±10.88公斤），分成常規訓練組、常規訓練配合循環訓練組、常規訓練配合速度、敏捷訓練組，除了實施網球的常規訓練外，並配合八週每週三次的不同訓練內容，透過訓練前後的評量，藉以做為訓練成效之檢討與改進之依據。本研究測驗結果資料，經統計分析獲得以下的結論：ㄧ、常規訓練對基本及專項體能效果之影響（一）常規訓練對基本體能效果之影響在基本體能的伏地挺身、仰臥起坐、屈身轉體、12分鐘跑、折返跑、50公尺跑的六個變項中有明顯的差異（p<.05）；而引體向上、垂直跳二個變項則無明顯改變。（二）常規訓練對專項體能效果之影響專項體能上的米字型折返跑、800公尺跑、立定跳遠、體前彎的四個變项中有明顯的差異（p<.05）；而30公尺跑、側併步這個二個變項則無明顯改變。二、常規訓練配合循環訓練對基本及專項體能效果之影響（一）常規訓練配合循環訓練在基本體能上之伏地挺身、仰臥起坐、屈身轉體、垂直跳、12分鐘跑、折返跑、50公尺跑的七個變項中有明顯的差異（p<.05）；而引體向上這個變項則無明顯改變。（二）專項體能上的米字型折返跑、30公尺跑、立定跳遠、側併步、體前彎的五個變项中有明顯的差異（p<.05）；而800公尺跑這個變項則無明顯改變。三、常規訓練配合速度敏捷性訓練對基本及專項體能效果之影響（一）常規訓練配合速度敏捷性訓練在基本體能上之伏地挺身、仰臥起坐、引體向上、屈身轉體、垂直跳、12分鐘跑、折返跑、50公尺跑的八個變項中有皆有明顯的差異改變（p<.05）。（二）在專項體能的米字型折返跑、30公尺跑、立定跳遠、側併步、體前彎、800公尺跑的六個變项中皆有明顯的差異改變（p<.05）。四、不同訓練內容對基本及專項體能效果之差異比較（一）不同訓練內容對基本體能效果之差異比較對伏地挺身、引體向上、折返跑、12分鐘跑而言，不同訓練法沒有差異存在。而仰臥起坐、屈身轉體、垂直跳、50公尺跑達非常顯著的效果，且常規訓練配合速度、敏捷性訓練效果均優於常規配合循環訓練及常規訓練的訓練效果。（二）不同訓練內容對專項體能效果之差異比較在30公尺跑、米字型跑、800公尺跑、立定跳遠、側併步、體前彎等，在訓練後皆有顯著的增進。且常規訓練配合速度、敏捷性訓練組的進步幅度均優於常規配合循環訓練組及常規訓練組。

　　The purpose of this research is to investigate the effects of various training program on general and specific fitness in Li Ming junior high school tennis players. Fifteen junior high school male tennis players (appendix A) are randomly assigned into three different groups: “the control group”, “the circuit training group” and “the speed and agility training group”. In addition to the regular tennis training, each group is treated additional training projects three a week for eight weeks long. Through the evaluations of before and after training, the result could be as a proposition for next movement.According to the statistic, the result of this research are as follows:1. Effects of general and specific physical fitness through general training:a. Effects of general fitness through regular training:There are apparent improvements on six variates: push-ups, sit-ups, wall-slaps,12mins run, shuttle run, and 50m dash (p<0.05). There are no apparentimprovements on pull-up and vertical jumps.b. Effects of specific physical fitness through regular training:There are remarkable improvements (p<0.05) on radiative shuttle run, 800mdash, standing long jump, sit-and-reach tests. There are no apparent improvements on 30m dash and side-step.2. Effects of general and specific physical fitness through regular and circuit training:a. There are eminent improvements (p<0.05) on push-ups, sit-ups, wall-slaps, vertical jumps. 12mins run, shuttle run, and 50m dash in general fitness, but there is no apparent improvement on pull-up.b. There are conspicuous improvements (p<0.05) on radiate shuttle run, 30m dash, standing long jump, sit-and-reach test in specific physical fitness, however, there is no obvious improvement on 800m run.3. Effects of general and specific physical fitness through regular, speed and agility training:a. There are obvious Improvements among the 8 varites (p<0.05) ： push-ups,sit-ups, wall-slaps, vertical jumps, 12mins run, shuttle run, 50m dash in general fitness.b. There are distinct improvement (p<0.05) on radiate shuttle run, 30m dash, standing long jump, side-steps, sit-and-reach tests and 800m run. 4. The comparison of various training programs in general and specific physical fitness: a. There is no dissimilarity among various training programs on push-ups, pull-ups, shuttle run, 12mins run in general fitness. Yet, there are remarkable improvements on sit-ups, wall-slaps, vertical jumps, and 50m dash through regular, speed and agility training among these three programs.b. There only pull-up variate has no obvious improvement in specific physical fitness after the training program. Nevertheless, through the regular, speed and agility program, 30m dash, radiate shuttle run, 800m run, standing long jump,side-steps, sit-and-reach tests have significant contribution.
