This article through to the man rowing athletes of hubei province for ergometry test of full 2 000m , understand the rowing athletes in ergometry test of full 2 000m muscle power sequence and the main muscle groups strength distribution ratio, fatigue and strength characteristics. The results showed that in ergometry test of full 2 000m, rowing athletes muscle power in the motion of a complete order: tibialis anterior>medial muscle> erector spinae> latissimus dorsi >deltoid muscle after the beam >biceps, Instantaneous higher iEMG values at the start of the game , as the game progressed iEMG value began to drop , to 1 500 m down to a minimum, and in the final sprint phase iEMG value maximum, the left side of the iEMG value is greater than the right; from the start to the end of the game, MF and MPF’s overall performance is increased with the increase of sports load and sports fatigue appeared a downward trend , but in the final sprint stage of MF and MPF are increased, but overall the drop is larger, increase amplitude is smaller.%目的：通过对湖北省男子赛艇运动员进行测功仪2000m全力划测试，了解赛艇运动员在测功仪2000m全力划中肌肉的发力顺序、各主要肌群力量分布比例情况、疲劳以及用力特点。研究方法：12名男子赛艇运动员测功仪2000m全力划，测主要用力肌群的表面肌电图。结果：在测功仪2000m全力划测试中，赛艇运动员一个完整的动作中肌肉的发力顺序为胫骨前肌＞股四头肌内侧头＞竖脊肌＞背阔肌＞三角肌后束＞肱二头肌；iEMG值在比赛一开始就瞬时升高，随着比赛的进行iEMG值开始下降，到1500m处下降到最低值，而在最后冲刺阶段iEMG值达到最大值，左侧iEMG值大于右侧；从比赛开始到比赛结束，MF和MPF整体表现为随着运动负荷的增加和运动疲劳的出现呈下降的趋势，在最后冲刺阶段MF和MPF都有所增加，总的来说其下降幅度较大，增加幅度较小。
