聳肩 Shrug
研究排名 Research Rankings
背 Back
聳肩主要練斜方肌上束，動作簡單好上手，但刺激範圍比較單一。研究顯示斜方肌不同部位需要不同角度來充分激活，單純聳肩可能無法全面發展整個斜方肌。 Shrugs primarily target the upper trapezius with a simple movement pattern, but provide limited stimulus range. Research indicates different trapezius regions require varied angles for optimal activation, so basic shrugs may not comprehensively develop the entire trapezius muscle.
聳肩的動作幅度很小，主要是等長收縮，對整體功能性力量幫助有限。研究發現斜方肌不同區域需要不同的測試動作來產生最大收縮，單純聳肩無法全面提升肩膀力量。 Shrugs have a very limited range of motion and primarily involve isometric contractions, offering minimal benefit for overall functional strength. Research shows different trapezius regions require different movement patterns for maximal contraction, so basic shrugs don't comprehensively improve shoulder strength.
借力風險 Compensation Risk
容易用手臂或背部其他肌肉借力，會看到肩膀往前捲或手肘彎曲。如果感覺不到斜方肌上束（脖子兩側）在用力就是借力了。 Common to use arms or other back muscles for assistance, visible as forward shoulder rolling or elbow bending. If you can't feel the upper traps (sides of neck) working, you're likely compensating.
新手建議 Beginner Tips
想像把肩膀往耳朵方向抬，保持手臂自然垂下，專注感受脖子兩側的肌肉收縮。 Imagine lifting your shoulders toward your ears while keeping arms naturally hanging, focus on feeling the muscle contraction on both sides of your neck.
