Abstract

Understanding muscle activation during exercises is crucial for devising effective training programs. We examined correlations between self-reported and electromyographic (EMG) muscle activity during upper-body exercises performed at loads corresponding to 4-6 repetition maximums (RMs). Thirteen male sub-elite soccer players who had previously engaged in resistance training participated in two testing sessions. In the initial session, the loads corresponding to 4-6 repetitions were determined for six exercises: Lat Pull Down (LPD), Barbell Bent Over Row (BBOR), Dumbbell Row (DR), Barbell Pull Over (BPO), Dumbbell Reverse Fly (DRF), and Dumbbell Concentration Curl (DCC). At post-exercise, participants rated their perceived muscle activation for three targeted muscles in each exercise on a 1-10 point Likert scale (LS). In the subsequent session, we used EMG to measure the activity of eight agonist and synergist muscles during these exercises. We found that one of two synergist muscles consistently demonstrated higher activity levels. Interestingly, we observed no difference in activity between primary and secondary (or synergist) muscles across all exercises. Most importantly, we found no significant correlation between the perceived muscle activation rate and the EMG measured activation level for any exercise. In conclusion, our findings suggest that, despite differential muscle activity during specific exercises, self-reported muscle activation may not accurately correspond to actual muscle activation, as measured via EMG, due to the participants' poor interoceptive awareness of muscles. These data highlight the potential limitations of relying on perceived muscle activation as a sole gauge of training intensity.

足球运动员感知到的肌肉激活与实际肌电图测量到的肌肉激活之间的脱节。
了解锻炼过程中的肌肉激活情况对于制定有效的训练计划至关重要。我们研究了自我报告的肌肉活动与肌电图(EMG)肌肉活动之间的相关性,这些肌肉活动是在上半身运动时以相当于 4-6 次最大负重(RMs)的负荷进行的。13 名曾参加过阻力训练的男性亚精英足球运动员参加了两次测试。在首次测试中,确定了六项练习的 4-6 次重复相应负荷:下拉 (LPD)、杠铃弯举 (BBOR)、哑铃划船 (DR)、杠铃上拉 (BPO)、哑铃反向飞举 (DRF) 和哑铃集中卷曲 (DCC)。运动后,参与者用 1-10 分的李克特量表(LS)对每次运动中三块目标肌肉的感知肌肉激活度进行评分。在随后的训练中,我们使用肌电图测量了这些练习中八块激动肌和协同肌的活动情况。我们发现,两块协同肌中的一块始终表现出较高的活动水平。有趣的是,在所有练习中,我们观察到主要肌肉和次要肌肉(或协同肌)的活动没有差异。最重要的是,我们发现在任何练习中,感知的肌肉激活率与 EMG 测量的激活水平之间都没有明显的相关性。总之,我们的研究结果表明,尽管在特定练习中肌肉活动存在差异,但由于参与者对肌肉的感知能力较差,自我报告的肌肉激活率可能与通过肌电图测量的实际肌肉激活率不一致。这些数据凸显了将感知到的肌肉激活作为衡量训练强度唯一标准的潜在局限性。
