摘要
研究目的本研究比较了大龄儿童中游泳运动员(A-S)和非运动员(N-A-S)的姿势控制和神经肌肉激活情况。方法:在睁眼(EO)和闭眼(EC)条件下,对 10 名 A-S 和 10 名 N-A-S 在静态和动态表面两个方向(动态内外侧(DML)和动态前胸(DAP))下的压力中心(CoP)参数以及在 EO 和 EC 条件下 DAP 和 DML 方向的肌电图(EMG)参数进行评估。结果显示结果显示,A-S 的姿势控制能力明显优于 N-A-S(P < 0.05),CoP 面积更小,CoP 平均速度更低,尤其是在静态与 EC、DAP 与 EO 和 EC 以及 DML 与 EO 条件下。A-S 的神经肌肉激活幅度明显更大(p < 0.05),尤其是在 AP 方向。结论这些研究结果表明,运动游泳训练可增强 11-13 岁儿童的姿势控制能力和神经肌肉活化能力,强调了在这些儿童中开展游泳训练的潜在益处。
Postural Control and Neuromuscular Activation in 11–13-Year-Old Athletic Boy Swimmers
Objective: This study compared postural control and neuromuscular activation in athletic swimmers (A-S) and non-athletic swimmers (N-A-S) in older children. Methods: Ten A-S and ten N-A-S underwent assessments of center of pressure (CoP) parameters under static and dynamic surfaces in two directions (dynamic mediolateral (DML) and dynamic anteroposterior (DAP)) in eyes-open (EO) and eyes-closed (EC) conditions, and electromyography (EMG) parameters under DAP and DML directions in EO and EC conditions. Results: Results showed that A-S demonstrated significantly superior postural control (p < 0.05), with smaller CoP area and lower CoP mean velocity compared with N-A-S, particularly in static with EC, DAP with EO and EC, and DML with EO conditions. A-S exhibited significantly larger neuromuscular activation amplitudes (p < 0.05), especially in the AP direction. Conclusions: These findings suggested that athletic swimming training may enhance postural control and neuromuscular activation in 11–13-year-old children, emphasizing the potential benefits of incorporating swimming exercises in these children.
