中文摘要 | 本研究主要目的在於以分段速度測驗的方式,探討體育系學生之助跑速度曲線變化及助跑速度利用率對跳遠成績之影響。受試對象為二十名體育系一年級男生,平均年齡為18.90±1.12 歲,平均身高為175.30±5.07 公分,平均體重為 65.60±7.42 公斤。以LDM300C 高頻測速槍(100Hz)記錄所有受試者50 公尺快跑及跳遠全程助跑運動學參數,所得資料以相依樣本t-test 和皮爾森積差相關進行統計分析。本研究所得結果如下: 一、50 公尺快跑平均分段速度在30~35 公尺達到分段最高速度。二、十三步和十七步助跑距離的跳遠成績均優於九步助跑距離(P<.05);其助跑距離介於22.70±1.06~30.61±1.48 公尺之間。三、全程助跑最後25 公尺速度曲線顯示,助跑速度隨著距離增加而增加,在起跳前(踩板前5 公尺)達到分段最高速度(8.93±0.43 公尺/秒)。四、全程助跑最後25 公尺分段速度均與跳遠成績達顯著相關(P<.05),其相關係數分別為r=.58, .64, .76, .75, .67(25 公尺至踩板)。五、助跑速度利用率平均值為94.80±4.2% ,與跳遠成績無顯著相關(P>.05)。本研究結論為:跳遠助跑過程之分段速度與跳遠成績均有相關趨勢,因此助跑練習的重點應著重在整個助跑過程加速能力之養成,受試者的助跑速度曲線和助跑速度利用率與預期的跳遠助跑觀念有落差,是否因實驗設計所造成,有待進一步研究。 |
英文摘要 | The purpose of this study was to investigate the impact of variation of run-up velocity curve and utilization rate of run-up speed on long jump. Twenty males studying in the Department of Physical Education served as participants, and their mean age, height and weight were 18.90±1.12years, 175.30±5.07 cm and 65.60±7.42 kg respectively. The Laster Distance Measurement 300 C system (100Hz) was used to record and analyze the full process of 50 meters and long jump kinematics data. Repeated measures t-test and the Pearson’s product-moment correlation were conducted. The summary of results was listed as follows: The participants reached the fastest velocity at the section of 30-35 meters during 50-meter sprint. The performances of long jump by 13-step and 17-step run-up were better than that by 9-step run-up (p < .05). The distance of 13-step and 17-step run-up is 22.70±1.06 – 30.61±1.48 meters. The curve of the run-up speed during the last 25 meters of whole run-up process indicated that the speed became faster associated with the increasing of running distance. The sectional velocity just before taking off (0– 5 meters) was the fastest (8.93± 0.43 m/s). Each sectional velocity of the last 25 meters of whole run-up process was significantly correlated with the performance of long jump (p < .05). The coefficients were .58, .64, .76, .75, and .67 respectively (from 25 meters to touch-abroad). The average utilization rate of the run-up speed is 94.80±4.2% which did not show significant relation with the performance of long jump (p > .05). The conclusion of this study is as follows: The velocity of each section of the run-up process is related to the performance of long jump; therefore, the focal point of run-up training should be emphasized on the accelerative skills. The participants’ curve of run-up velocity and utilization rate of the run-up speed are inconsistent with researcher’s expectation, which needs to be further explored if those findings resulted from experimental design. |
