小球體接發球訓練對大專男子排球選手接發球成效影響之研究

Influence of small ball training on the serve reception performance of male university volleyball players

目的：本研究目的為探討大專男子排球選手使用不同尺寸的排球練習後，對接發球技能的影響。方法：本研究以中華民國大專男子排球公開一級 20名選手為受試對象，以分層隨機取樣法 (Stratified Sampling) 區分成小球體接發球訓練組 10名 (small ball training group, SBTG) 及一般接發球訓練組10名 (normal ball training group, NBTG)，進行六周的訓練計畫。以排球發球機進行接發球訓練，球速設定為 16.98m/s，每球間隔時間為八秒。在訓練前 (week 0)、第3週 (week 3) 及第6週 (week 6) 進行接發球技巧測驗。統計方法採用二因子變異數分析 (group x weeks)，若二因子作用達顯著水準，則進行單純效果考驗，若交互作用未達顯著水準，則以主要效果考驗。結果：經由分析後的結果顯示，兩組別都隨著周數的增加而逐步改善接發球的技巧，而SBTG在week-6時更是顯著的優於NBTG。兩組在經過 6周的訓練後分別提升了 20.40% (SBG)與6.01% (NBTG)，這顯示出隨著時間的推進的確產生了學習效應。結論：主要發現為，SBTG和NBTG都能夠對接發球測驗有正面的影響，且SBTG的成效顯著的較佳。

 

Purpose：The purpose of this study was to investigate the volleyball players’ ability and efficacy in serve reception, and whether it can be effectively improved after serve receive training with a small ball. Methods：In this study, twenty male volleyball players in Level 1 from Taiwan’s University Volleyball League were recruited as research participants. The participants were divided into two groups by stratified sampling to undergo a six-week training program: 10 in the small ball training group (SBTG), and 10 in the normal ball training group (NBTG). The volleyball machine was used in the experiment and the ball speed (from the volleyball machine) was 38 mph (= 61.16 km/h, = 16.98 m/s). The time interval was set at 8 seconds for each reception. The serve reception performance of both groups was evaluated before the training (Week 0), at third week (Week 3) and at the sixth week (Week 6) of the training. A two-way analysis of variance (group x weeks) was applied to analyze the data. If a significant interaction between the factors was found, the simple main effect would be assessed. If the interaction was not significant, the main effects would be assessed. Results：The results revealed a significant difference between two groups (p < .001). The results of the analysis also showed that the serve reception efficacy of participants in both groups gradually improved as the number of weeks increased, while SBTG achieved significantly greater results than NBTG at Week 6. After six weeks of training, the scores of the two groups increased by 20.40% (SBTG) and 6.01% (NBTG), showing that the training were effective indeed. Conclusion：The main finding was that both small ball and normal ball training had a positive effect on serve reception, while the influence of small ball training was more significant.
