| 摘要: | 背景與動機：足球賽中因進攻難度高，再加上防守方的幹擾，以致進攻得分的成功率更低。當進攻球隊陷入僵局之際，踢定位球即成為一項較易得分的方式之一。足球員踢定位球的優劣判斷主要以落點精確為原則。過去足球力量與技術訓練大多僅著眼於強化雙腳力量，即雙邊訓練 (bilateral training) ，但卻忽略單腳，即單邊訓練 (unilateral training）。目的：本研究旨在探討6週單邊肌力訓練對青少年足球選手踢任意球之精準度與專項能力指標之影響。方法：招募20名青少年男性足球運動員（年齡：16.7 ± 0.66歲)。每週進行3次單邊肌力訓練，同時進行5次常規足球訓練。主要評估檢測項目為精準度能力 (足球打靶測試)、敏捷 (505 agility test)、速度 (30公尺衝刺)、平衡測驗 (Y-Balance Test)－左腳站立 (LYBT)，右腳站立 (RYBT) 等。統計方法是利用相依樣本t檢定比較單邊訓練組之前測、後測所有參數，並以α =0.05 為顯著性考驗水準。結果：精準度（t= 2.29；p= .034<0.05）、30公尺短跑成績 (t= -10.735；p= 0.002< 0.05)、敏捷能力 (t= -10. 735；p= 0.000 <0.05)、平衡 (LYBT：t= 14. 64, p= 0.000<0.05、RYBT：t= 11.66，p=0.000<0.05)；皆具統計顯著意義。結論：青少年運動員在進行6週單邊訓練後，對於踢球精準度、敏捷、速度以及平衡能力方面皆獲得顯著有效改善。
Background and Motivation: Due to the complexity of offensive skills and the interference of the defensive players, it decreased the successful rate of scoring in the soccer game. When the offensive team met a standoff, Lace-Kick may be one of the optimal choices to score. Moreover, how to judge the level of soccer players in lack-kick performance focused mainly on the accuracy of kicking. In the past, the strength and technique training method in soccer always strengthened both two-legs strength (bilateral training) but neglected one foot (unilateral training). Purpose: This study aimed to investigate the effects of 6-week unilateral resistance training on the accuracy in Lace-kick and soccer-specific abilities in the young soccer players. Methods: 20 male soccer athletes were recruited as the experimental subjects (age = 16.7 ± 0.66 years old). The experimental intervention included three sessions of unilateral strength training per week with 5-day regular soccer training. The assessment was as below: Accuracy ability (lace-kick test), Agility (505 agility test), Speed (30 m sprint), and as well as Balance (Y-Balance Test: left foot standing, LYBT; and right foot standing, RYBT). The statistical method utilized the dependent sample t-test to compare all parameters before and after the unilateral training. The statistical significance was set as α= 0.05. Results: The results showed that all parameters appeared statistical significance in Accuracy of Lace-keck performance (t = 2.29, p = 0.034 <0.05), 30-Meter Sprint (t = -10.735, p = 0.002 < 0.05), Agility (t = -10.735, p = 0.000 < 0.05), Balance (LYBT: t = 14.64, p = 0.000 < 0.05; RYBT: t = 11.66, p = 0.000 < 0.05). Conclusion: After six-week unilateral training, young soccer athletes improved significantly in the accuracy of kicking, agility, speed, and balance. |
