摘要
本研究的目的在於探討固定式與平衡式測功儀之划槳動作力量與肌電表現之研究，實驗受試者為台北市立體育學院水上系輕艇專長運動員共9名，運動員平均年齡、身高、體重分別為：21.44（±1.67）歲、172.68（±6.46）公分、68.42（±8.79）公斤，每位運動員分別接受30sec固定式與平衡式測功儀划槳動作力量與肌電表現的測驗，其中過程以輕艇專項測功儀、張力計、電極片，經由同步訊號處理器、BioPac MP-150，取得划槳動作力量與肌電表現相關運動學資料。
並透過SSPS10.0分析軟體中的相依樣本t考驗、皮爾遜積差相關處理運算資料，及利用Excel繪圖製作表格，研究的結果顯示：
(一) 在划槳動作力方面，固定式比平衡式測功儀之划槳衝量無異。
(二) 在划槳作用肌群方面，固定式和平衡式測功儀之划槳表現上，
肱三頭肌、肱二頭肌、肩三角肌皆有差異。
(三) 肱二頭肌的iEMG與衝量顯現正相關。
(四) 平衡式測功儀較適合在考驗運動員的專項技術層面上，而固定式測功儀較適合評估運動員專項體能訓練上，此兩種測功儀亦可作為此專項運動科學選材之評估依據。

The study of EMG and strength performance in different ergometers 2005.7.15 Sheng-wei Dai Advisor: Su-Yun Shue Abstract The main purpose of this study was to investigate if EMG and strength performance were significantly different when using two different ergometers: the Constant model(C) and Self-Balance model (SB). Nine Canoe athletes from Taipei Physical Education College had been chosen in this study and the subjects’ average age, height and weight were 21.44（±1.67）yrs, 172.68（±6.46）cm, 68.42（±8.79）Kg respectively. All subjects were assigned to paddle in C and SB ergometer for 30 seconds each and their EMG for relative muscle contraction were recorded by using tensiometer, electropad, information synchronizer and Bio-Pac MP-150. The dependent T-test was calculated by using SPSS (10 Ed.) and Microsoft Excel was used to produced figures and tables of the results. The study has shown: (a) The momentum of paddling in C and SB were not significantly different. (b) The relative contracting muscle groups (triceps brachii, biceps brachii and deltoids) when using C and SB were different. (c) iEMG of biceps brachii was positively correlative with the momentum. (d) SB ergometer was more suitable when examining specific canoe techniques. However C ergometer is more appropriate when evaluate canoe athletic ability. Both SB and C can be use when selecting canoe talent. Keywords: K-1, canoe ergometer, EMG, muscle efficiency
