摘要
目的：立式划槳Stand up paddle (SUP)是台灣這一、兩年來流行的水上休閒運動，站在SUP時因水上的不穩定性，需要維持身體的平衡與核心的穩定，且為了在水上保持平衡，需要更多的專注力。在國外已有許多教練將瑜珈與SUP做結合，稱為水上瑜珈(SUP YOGA)，就是倚靠SUP平面在上面執行瑜伽動作，但目前尚未有特別針對水上瑜珈的肌肉活化研究，也較少有在不穩定平面執行完整瑜珈動作的肌肉活化文獻，因此本實驗將利用常見的瑜珈動作搭配水上的不穩定性，調查與陸地上執行瑜珈動作的肌肉活化差異性。 方法：共有26位受試者參與實驗，採用Delsys Trigno (Trigno TM Wireless system, Delsys Inc., USA)，測量肌肉位置分別是：腹直肌、腹外斜肌、股直肌、豎脊肌與多裂肌。在陸地和SUP平面時執行的瑜珈動作皆一致，分別是：山式、前彎式、鴕鳥式、高弓箭步、高棒式、低棒式、上犬式及下犬式。測量後的肌肉活化數值會使用Wilcoxon Signed-Rank Test比較兩種平面下的差異。 結果：根據研究結果顯示，腹直肌在執行山式、前彎式以及高棒式時的肌肉活化與腹外斜肌執行低棒式、上犬式時的肌肉活化皆為陸地顯著高於SUP；豎脊肌執行前彎式、上犬式與下犬式和多裂肌執行山式、前彎式、鴕鳥式、上犬式以及下犬式時也皆為陸地顯著高於SUP。 結論：本研究在SUP上進行常見瑜珈的肌電圖測量，在結果部分，肌肉活化數據是陸地高於SUP，但在執行整套瑜珈動作的全程都是不穩定平面的情況下，可能會為了維持平衡而活化其他未測量到的肌群，例如：上肢肌群及下肢臀肌、股二頭肌與小腿肌群。

Purpose: Stand up paddle (SUP) is a popular water sport in Taiwan for recent years. When standing on SUP, it is necessary to maintain balance and core stability due to water instability, and need to more focus to maintain balance on the water. Many foreign coaches have combined the yoga with SUP, called SUP YOGA, which depend on SUP board to perform yoga pose. However, there is a bit less research on muscle activation specifically for SUP yoga or muscle activation for performing complete yoga movements on unstable planes. Therefore, this study performed SUP yoga on the water that provide the instability, and compared the muscle activation of performing SUP yoga with on the land. Method: 26 people with SUP Yoga experience were recruited into this study. The equipment included Stand Up Paddle and Delsys Trigno (Trigno TM Wireless system, Delsys Inc., USA). The dominant side muscles: Rectus abdominis (RA), External oblique (EO), Rectus femoris (RF), Erector spinae (ES), and Multifidus (MF) were measured. Each subject was instructed to perform the same Yoga pose: Mountain pose, Forward fold, Halfway lift, High plank, Low plank, Upward facing dog, Downward facing dog in land and SUP conditions. The Wilcoxon Signed-Rank Test was used to compare the iEMG, mean value, and peak value of muscle activation, among the two conditions. Results: The results show that the RA muscle expressed significantly higher muscle activation on land than the SUP in Mountain, Forward fold, and High plank poses. For the EO muscle, there were significantly higher muscle activation on land than the SUP in the Low plank, and Upward facing dog poses. Besides, the Forward fold, Upward facing dog, Downward facing dog poses for the ES muscle and the Mountain, forward fold, Halfway lift, Upward facing dog, Downward facing dog poses for MF muscle also expressed significantly higher muscle activation on land than the SUP condition. Conclusion: In this study, we used the EMG analysis to compare the difference between common yoga poses performed on land and SUP. Although the muscle activation on land was higher than SUP, but the other muscle groups may also activate to maintain balance on the SUP. Future study are required to measure other muscles (i.e. upper- or lower limbs muscle), which would offer insights as to the muscle activation pattern of SUP yoga.
