The aim of this study was to determine the muscle activations of the dominant arm during the forehand stroke of wheelchair tennis. Five players participated in the present study (age: 32.6 ± 9.9 years; body mass: 63.8 ± 3.12 kg; height: 164.4 ± 1.7 cm). The electrical muscle activity of six dominant arm muscles was recorded using an sEMG system. A significant effect of the muscle's activity was observed, and it was shown that the muscle activation was significantly higher in the execution phase compared to the preparation phase in the anterior deltoid and biceps brachii (34.98 ± 10.23% and 29.13 ± 8.27%, < 0.001); the posterior deltoid, triceps brachii, flexor carpi radialis, and extensor carpi radialis were higher in the follow-through phase than in the execution phase (16.43 ± 11.72%, 16.96 ± 12.19%, 36.23 ± 21.47% and 19.13 ± 12.55%, < 0.01). In conclusion, it was determined that the muscle activations of the dominant arm muscles demonstrate variances throughout the phases of the forehand stroke. Furthermore, the application of electromyographic analysis to the primary arm muscles has been beneficial in understanding the muscular activity of the shoulder, elbow, and wrist throughout the various phases of the forehand stroke in wheelchair tennis.
本研究旨在确定轮椅网球正手击球时优势手臂的肌肉活动。本研究共有 5 名运动员参与（年龄：32.6±9.9 岁；体重：63.8±3.12kg；身高：164.4±1.7cm）。使用肌电图系统记录了 6 块优势手臂肌肉的电肌活动。观察到肌肉活动有显著影响，结果表明，三角肌前束和肱二头肌在执行阶段的肌肉激活显著高于准备阶段（34.98±10.23%和 29.13±8.27%，<0.001）；三角肌后束、肱三头肌、桡侧腕屈肌和桡侧腕伸肌在随挥阶段的肌肉激活高于执行阶段（16.43±11.72%、16.96±12.19%、36.23±21.47%和 19.13±12.55%，<0.01）。总之，确定了优势手臂肌肉在正手击球的各个阶段的肌肉激活存在差异。此外，对主手臂肌肉进行肌电图分析有助于了解轮椅网球正手击球各阶段肩部、肘部和手腕的肌肉活动。
