中文摘要 | 本研究目的,旨在比較一步及三步助跑對足球守們員自拋迎空踢球動作之影響,探討之變數如下:助跑步幅、踢球腳之足直線位移和速度、踢球腳之小腿角位移及速度、踢球腳之大腿角位移和角速度、軀幹角位移及角速度、支撐腳蹬地力量、球離手拋出之高度、球與踢球腳接觸之高度及水平距離、球踢出之角度、球速。 本研究以我國社會甲組球隊守門員一名及國家代表隊守門員二名為受試者。所有受試者的踢球動作為持球直線助跑一步及三步,再將球拋出,並以足背迎空盡全力踢球。以一部佳能脾(Canon)十六度米攝影機,拍攝速度定為每秒六十四張影片,從踢球動作方向之側面拍攝。使用先鋒牌動作分析器(Vangard Motion Analyzer)測量每張影片中身體關節及球中心點座標數值,並輸入電腦運算有動學變數資料。應用竹井牌測力板(TKK Varied Force Mcasuring Board) 及高得(Gould)多用途記錄器,求得支撐腳蹬地力量資料。將所有變數資料,應用相依樣本t-test公式,考驗兩種助跑踢球動作變數之間的差異性。有關資料結果,經分析討論後,待到結論如下: 在兩種助跑之間 (一)助跑步幅,無顯著差異存在(p>O.O1)。 (二)踢球腳之足直線位移及速度、小腿角位移及角速度、大腿角位移及角速度,皆無顯著差異存在(p>O.O1)。 (三)軀幹角位移及角速度,無顯著差異存在(p>O.O1)。 (四)支撐腳蹬地力量,無顯著差異存在(p>O.Ol)。 (五)球離手拋出高度、球與踢球腳接觸之高度及水平距離、球踢出之角度和球速,無顯著差異存在(p>O.O1)。 |
英文摘要 | The purpose of this study was to investigate the effects of different steps of approach on soccer goalkeeper of punt. The selected variables under investigation were: final approach stride, linear displacement and velocity of the kicking foot, angular displacement and velocity of the kicking shank and thigh, angular displacement and velocity of the trunk, force of the supporting foot versus ground, height of ball at drop, height and horizontal distance of the ball at contact, launch angle of the ball, and initial velocity of the ball. The subjects in this study were two goalkeepers from R. O. C. Men's National Soccer Team and one goalkeeper from R. O. C. Men's Open A Soccer Team. All subjects were requested to approach straight ahead with one and three steps and to punt the ball with instep when ball was dropped. A Canon Scopic 16MS Camera with 64 frames per second was used to take film on the side of kicking direction. Vangard Motion Analyzer was employed to digitize spatial coordinates of joint and ball center on each frame. Computer was utilized in computation of kinematic variables data. TKK Varied Force Measuring Board and Gould Varied Recorder were used to calculate the force of the supporting foot versus ground. A dependent t-test was employed to determine if there was a significant difference in any of the variables as a result of the two approach methods. The results of this investigation appear to warrant the following conclusions: (1) The final approach stride was not significant difference between two approach methods (p>O.O1). (2) The linear displacement and velocity of the kicking foot; the angular displacement and velocity of the shank and thigh were not significant difference between two approach methods (p>O.O1). (3)The angular displacement and velocity of the trunk were not significant difference between two approach methods (p>O.O1). (4) The force of the supporting foot versus ground was not significant |
