Abstract

Purpose Rowing engages large muscle groups, and EMG analysis is used to assess athletes' condition and refine sports technique. The aim of the experiment was to evaluate the muscle activation level during different phases of the rowing cycle on an ergometer. Methods In a study involving one professional and five amateurs, the mean EMG amplitudes from the quadriceps, gastrocnemius, biceps, and triceps brachii were analyzed during different phases of rowing. A comparison was made between the degree of muscle engagement during the exercise between the professional and inexperienced individuals, as well as among the different individuals during recordings obtained at different rowing speeds. The correlation coefficient between the values recorded using a strain gauge and the EMG amplitude recorded from the surface of the biceps and triceps brachii muscles was evaluated. Results The muscle activation pattern during rowing has a predictable character. A difference in the muscle activation pattern during rowing between the professional and amateurs was observed. The EMG signal is correlated with the force recorded by the resistive strain gauge only in the experienced rower at a pace of 20 and 25 cycles per minute. Conclusions Electromyographic analysis can be useful for assessing the correctness of rowing techniques. The activation pattern of muscles during rowing has a predictable nature. The force generated by the participants increases with an increase in rowing frequency.
划船阶段的肌肉活动分析
赛艇运动涉及大肌肉群,肌电图分析用于评估运动员的状态和改进运动技术。实验的目的是评估在划船周期的不同阶段肌肉的激活水平。方法对一名专业运动员和五名业余运动员进行研究,分析他们在划船不同阶段的股四头肌、腓肠肌、肱二头肌和肱三头肌的平均肌电波幅。我们比较了专业运动员和没有经验的运动员在运动过程中的肌肉参与程度,以及在不同划船速度下记录的不同运动员之间的肌肉参与程度。利用应变计记录的值与肱二头肌和肱三头肌表面记录的肌电振幅之间的相关系数进行评估。结果划船运动中肌肉的激活模式具有可预测性。在划船过程中,专业选手和业余选手的肌肉激活模式有所不同。肌电图信号与电阻应变计记录的力仅在经验丰富的划船者中以每分钟20和25个周期的速度相关。结论肌电图分析可用于评估划船技术的正确性。划船时肌肉的激活模式具有可预测性。参与者产生的力随着划船频率的增加而增加。
