應用馬克操高抬腿技術進行八週訓練對國中田徑選手速度、爆發力之影響 摘要 本研究主要是以運動生物力學研究方式來確認與掌握馬克操高抬腿技術的特性,並且應用該技術針對國中田徑選手進行八週訓練,進而了解此動作技術訓練對於國中田徑選手速度與爆發力的影響。實驗以7名具有多年訓練經驗的田徑選手(男性3名、女性4名)進行下肢關節角度及推蹬參數分析;之後則以14名台南市金城國中田徑隊選手(男、女各7名)進行為期八週的馬克操高抬腿技術訓練並且進行速度與爆發力的前後測比較,研究結果顯示:(一)和馬克操一般抬腿動作比較起來,高抬腿動作在技術上,可讓抬腿腳之抬腿垂直高度提升,另外下肢也會產生較大的推蹬力,能充分發展跑步下肢動作技術,符合國中田徑選手訓練的需求。(二)馬克操高抬腿動作足部最大負荷率較一般抬腿動作大,在訓練時應注意訓練量,以免發生運動傷害。(三)馬克操高抬腿技術訓練對於選手下肢爆發力與短跑速度皆有助益,特別在速度表現上有較大之提升。(四)在接受馬克操高抬腿技術訓練後,男、女性選手成績進步的幅度並無差異的,顯示性別並不會對於國中男、女性選手的進步幅度造成影響。(五)在後續研究中,可針對馬克操高抬腿技術進行更多的運動生物力學與運動訓練研究,進而對於該技術能有更為廣泛之了解與運用。
The effect of 8 weeks training applying high lifting leg technique Mach Drills on speed and power of junior high school students Abstract In this study, the characteristics of high lifting leg technique of Mach Drills were certified and grasped by the researching method of sports biomechanics. Then, high lifting leg technique was applied in one 8 weeks training focused on junior high school students. Furthermore, the effect of the training of high lifting leg technique on junior high school students’ speed and power performance could be comprehended. In experiment, 7 track and field athletes accepted training for many years were served as subjects (3 males and 4 females) in the analyzing of lower extremity parameters including joint angles and push off data. Afterward, 14 track and field athletes from Jincheng junior high school in Tainan City (including 7 males and 7 females) were recruited to accept the training of high lifting leg technique of Mach Drills for 8 weeks; meanwhile, pre-test and post-test of speed and power were executed and compared. The results showed: 1. Comparing with normal lifting leg technique of Mach Drills, high lifting leg technique let lifting leg to rise to the higher vertical height and to produce bigger pushing force. This result meant high lifting leg technique was beneficial to develop the lower extremity technique of running and fit with the requirement of junior high school athletes’ training. 2. The maximum loading rate of foot IV in high lifting leg technique of Mach Drills was bigger than the rate in normal lifting leg technique. It meant the amount of high lifting leg technique training should be took care to avoid the sports injury. 3. The training of high lifting leg technique of Mach Drills was helpful for the power of lower extremity and the speed of sprint, especially for the speed of sprint. 4. After the undergoing of high lifting leg technique training, the progressive scopes of testing performance between male and female athletes weren’t different significantly. So sex wouldn’t affect the advance ranges of male and female subjects. 5. More sports biomechanics and training studies aimed at high lifting leg technique of Mach Drills could be carried out in the future to understand and apply more relating this technique.
