摘要：

文题释义：
加压训练：指使用专业的加压绑带，对身体上肢或下肢的根部施加一定的压力，使血液循环受到适度控制，并在这种状态下进行低负荷运动的方法。
均方根值(root mean square，RMS)：表面肌电是一种使用表面电极，相对安全、无创和操作简单的肌电图，能记录肌肉收缩时产生的电位变化，从而产生肌电图和反映相关肌肉活动特征的参数。均方根振幅(RMS)是表面肌电数据中用来反映肌电信号的幅值大小变化的指标，可以表示信号的集中趋势，与运动单位的募集和兴奋节律的同步化有紧密联系，研究表明通过RMS值可以显示肌肉的激活程度，应用于运动功能测试及康复的评价。

背景：加压四肢低强度训练能对四肢产生肌肉肥大的作用，但是加压四肢低负荷训练能否对核心肌群产生积极影响，研究较少。
目的：探讨加压四肢低负荷训练对核心肌群的表面肌电、等速屈伸肌力的影响，旨为各类需要提高核心肌群力量人群的运动康复训练提供理论依据。
方法：将16名在校大学生按随机数字表法分为加压组(n=8)和对照组(n=8)。加压组进行加压四肢低负荷训练，在四肢加压条件下进行3组25%1RM的5个训练动作；对照组进行低负荷训练，7周后比较表面肌电、等速肌力的变化。研究方案的实施符合《赫尔辛基宣言》和成都体育学院对研究的相关伦理要求，受试者为自愿参加，对试验过程完全知情同意。
结果与结论：①躯干屈曲动作训练后，加压组腹直肌、腹外斜肌的肌电信号均方根值显著大于训练前和对照组训练后(P < 0.05)；②躯干伸展动作训练后，加压组的竖脊肌、多裂肌的肌电信号均方根值显著大于训练前和对照组训练后(P < 0.05)；③站姿腿伸展动作训练后，加压组的竖脊肌、多裂肌的肌电信号均方根值大于训练前和对照组训练后(P < 0.05)；④卧推和坐姿伸膝动作训练后，核心肌群的肌电信号均方根值差异均无显著性意义(P > 0.05)；⑤加压组在测试角度为30，90和120 (°)/s时躯干屈肌峰力矩显著小于训练前，伸肌峰力矩显著大于训练前(P < 0.05)；⑥7周规律的加压四肢低负荷训练能对核心肌群达到肌肉锻炼效果。

Abstract: BACKGROUND: Low-load compression training of the extremities can produce muscle hypertrophy in the extremities, but whether the training can exert a positive effect on the core muscles is rarely reported.
OBJECTIVE: To explore the effects of low-load compression training of the extremities on the surface electromyography and isokinetic flexor and extensor strength of core muscles, aiming to provide theoretical basis for sports rehabilitation training for people who need to improve core muscle strength.
METHODS: Sixteen college students were divided into a compression group (n=8) and a control group (n=8) according to a random number table. In the compression group, three sessions of five training actions with 25% 1RM were performed under the condition of extremity compression. Low-load training was performed in the control group. After 7 weeks, the changes in surface electromyography and isokinetic muscle strength were compared between two groups. The study protocol complied with the Declaration of Helsinki and the relevant ethical requirements of Chengdu Sport University. Each subject was voluntary to participate in the trial and fully informed of the trial process.
RESULTS AND CONCLUSION: After trunk flexion training, the root mean square of surface electromyography signal of the rectus abdominis and external oblique muscles in the compression group was significantly different from those before training as well as those in the control group after training (P < 0.05). After trunk stretching training, the root mean square of surface electromyography signal of the erector spinae and multifidus muscles in the compression group was significantly different from those before training and those in the control group after training (P < 0.05). After standing leg stretching training, the root mean square of surface electromyography signal of the erector spinae and multifidus in the compression group was significantly different from those before training and those in the control group after training (P < 0.05). After bench press and sitting knee extension training, there was no significant difference in the root mean square of surface electromyography signal of core muscle groups (P > 0.05). In the compression group, the trunk flexor and extensor peak torque tests at the test angles of 30, 90 and 120 (°)/s were significantly different from those before training (P < 0.05). To conclude, the 7-week regular low-load compression training of the extremities can build the core muscles.
