目的:本研究探討增強式訓練對高年級籃球隊男童爆發力、速度及敏捷性之影響。方法:以16名籃球隊男童為研究對象,隨機分為訓練組(11.77±0.26歲)及控制組(11.77±0.15歲)各8名,所有受試者都接受1週3次的籃球訓練,但訓練組外加每週2次的增強式訓練,為期12週,訓練過程採漸進式原則,技巧由簡單變複雜,但總訓練量(組數×重複次數)也逐漸減少,以維持受試者的學習動機及避免運動傷害。所有受試者在訓練前後均進行爆發力(立定跳遠和垂直跳)、速度(30公尺衝刺跑)及敏捷性(10公尺×4折返跑)測驗。所得資料以相依樣本t考驗檢定訓練組及控制組前後測差異,再以獨立樣本單因子共變數分析,比較兩組訓練效果,統計顯著水準定為α=.05。結果:前後測差異比較,控制組在爆發力測驗項目達顯著水準,而速度與敏捷性測驗則未達顯著水準;訓練組在爆發力、速度及敏捷性測驗皆達顯著差異水準。經共變數分析,訓練組在立定跳遠、垂直跳、30公尺衝刺跑及10公尺×4折返跑的表現,均優於控制組,且達到顯著水準(p<.05)。結論:訓練籃球隊男童,採用增強式訓練,可以提升爆發力、速度及敏捷性。
Purpose: This research was to explore the effects of plyometric training on power, speed and agility in 6th grade male basketball players. Methods: Sixteen male players were assigned randomly to training group (11.77±0.26 yrs) or control group (11.77±0.15 yrs). All subjects underwent regular basketball training 3 times a week while training group practiced extra plyometric training 2 times a week for 12-week. Training intensity and techniques were progressively changed from first week to last week. In order to avoid injury and maintain subjects' motivation, the total amount of training (set × repetition) was progressively reduced. All the subjects performed standing long jump, vertical jump, 30 m sprint and 10 m × 4 shuttle-run tests before and after training. The pair-sample t-test was used to analyze each group between pretest and post-test. One Way ANCOVA (analysis of covariance) was conducted to compare the effects between the groups. The statistical significance is set at α=.05. Results: The training and control group both showed significant improvements on standing long jump and vertical jump tests, but only the training group showed significant improvements on 30 m sprint and 10 m × 4 shuttle-run tests after training. After training, the training group performed better than the control group on the standing long jump, vertical jump, 30m sprint and 10 m × 4 shuttle-run significantly (p<.05). Conclusion: 12-week plyometric training could be applied in 6th grade male basketball players to improve power, speed and agility.
