Volleyball and handball have typical overhead throwing motion that can generate adaptations in the athlete's kinetic chain predisposing to injuries and pain. Considering the importance of the trunk and shoulder in overhead throwing motion and the particularities of these action in different sports, this study aimed to compare the trunk and shoulder muscle strength and mobility in young female volleyball and handball athletes.
Cross-sectional study with 70 female volleyball and handball athletes between 13 and 18 years old.
Shoulder rotators, trunk extension and flexion with rotation strength was measured with a handheld dynamometer (MicroFET 2, Hoogan Health Industries, West Jordan, UT, USA). Shoulder and trunk range of motion was measured with a digital inclinometer (Acummar - model ACU001). Total range of motion deficit (TROM deficit), glenohumeral internal and external rotation of dominant (DOM) and non-dominant (NDOM) shoulder were also calculated.
Handball athletes presented greater muscle strength of trunk flexors/rotators (DOM: 24.96%, effect size: 0.687; NDOM, 31.83%, effect size: 0.798) and dominant shoulder internal rotators (16.65%, effect size: 0.619). The groups showed no difference for trunk and shoulder range of motion and external rotators strength. A TROM (volleyball: 48%, handball: 35%) and a glenohumeral internal rotation deficit (volleyball: 28%, handball: 29%) was found in both groups.
Young female handball athletes have greater strength of trunk flexors/rotators and dominant shoulder internal rotators compared to volleyball athletes. These differences may be related to the different demands required in the movement of these sports.
排球和手球都有典型的头顶投掷动作，这可能会使运动员的运动链产生适应性变化，从而导致受伤和疼痛。考虑到躯干和肩部在头顶投掷动作中的重要性，以及这些动作在不同运动中的特殊性，本研究旨在比较年轻女性排球和手球运动员的躯干和肩部肌肉力量和灵活性。
横断面研究，共有 70 名年龄在 13 至 18 岁的女性排球和手球运动员参与。
使用手持测力计（MicroFET 2，Hoogan Health Industries，West Jordan，UT，USA）测量肩部旋转肌、躯干伸展和旋转力量。使用数字测斜仪（Acummar - model ACU001）测量肩部和躯干的活动范围。还计算了总活动范围缺陷（TROM 缺陷）、优势（DOM）和非优势（NDOM）肩部的盂肱关节内、外旋转。
手球运动员的躯干屈肌/旋转肌（DOM：24.96%，效应量：0.687；NDOM：31.83%，效应量：0.798）和优势肩内旋肌（16.65%，效应量：0.619）的肌肉力量更强。两组在躯干和肩部活动范围以及外旋肌力量方面没有差异。两组均存在总活动范围缺陷（排球：48%，手球：35%）和盂肱关节内旋转缺陷（排球：28%，手球：29%）。
与排球运动员相比，年轻女性手球运动员的躯干屈肌/旋转肌和优势肩内旋肌力量更强。这些差异可能与这些运动中不同的运动需求有关。
