Zusammenfassung

本研究旨在探討羽球殺球動作手臂肌群的肌肉活化程度的現象以及其共同收縮情形的不同，以作為訓練的根據。本研究以國立新竹師範學院五名羽球隊選手及五名非羽球選手為研究對象，使用肌電訊號擷取系統記錄殺球動作六條相關肌肉的肌電訊號，同時以加速規及高速攝影機來判斷羽球殺球動作之分期，計分為引拍期、揮拍期、擊球期。本研究所記錄之數據採用獨立樣本t 考驗進行統計考驗，顯著水準訂為α=.05，並輔以文獻之探討，獲致結果如下： (一)羽球殺球動作過程之引拍期與揮拍期，選手組肱二頭肌活化程度均優於非選手 組，且擊球期的前三角肌、肱三頭肌、屈腕肌及伸腕肌均有顯著的活化現象。 (二)引拍期階段選手組上臂肱二頭肌與肱三頭肌比值大於非選手組且達顯著水準，顯示選手組在引拍期階段上臂肌間協調能力優於非選手組；同時選手組在擊球時手腕關節穩定性優於非選手組。 本研究認為在訓練上應加強選手的前三角肌、肱三頭肌、肱二頭肌、伸腕肌及屈腕肌的快速收縮能力，並建議爾後的研究應朝向殺球時全身肌群肌電之分析。 The purpose of this research was to study both the phenomenon of the active level in arm muscle groups of smashing shuttle action, and the difference of co-contract, in order to be the base of the training. Five players and five non-players in National Hsin-chu Teachers’ college were studied. We used electromyogram signal to measure systematic records of six relative muscles. Also, we used acelerate gauge and high-speed camera to judge the different stages: pulling, waving, and hitting stages. We used individual sample t-test to compile statistics; conspicuous standard was set α=.05; the result was as below: 1. In the stage of pulling and waving, the active level of biceps brachii of players was better than non-players. In the stage of hitting, deltoid anterior, triceps, flexor carpi and extensor carpi were obviously activated. 2. In waving stage, the ratio of biceps brachii and triceps of players were bigger than non-players’ obviously, that was to say, players’ upper arm muscle coordination was better than non-players. In addition, players’ wrist joint stability was better than non-players’ while hitting the ball. We concluded in the training program that we should reinforce the speed contraction ability of deltoid anterior, triceps, biceps brachii, extensor carpi and flexor carpi. Also, we suggested the future research should emphasize on the analysis of arm muscle groups and electromyography of whole bodies during badminton smashing movement.
