摘要:

文题释义:

肌肉伸展性:是指肌肉放松状态下的机械张力,描述肌肉处在动作和放松状态之间的恢复反复状况。伸展性高于正常值将会扰乱肌肉中的血流状况,因为肌肉中的血管越是收缩血液就越少回流到达肌肉,肌肉伸展性升高将导致疼痛、运动能力下降、过载和其他现象,但较低的伸展性又显示较低的运动能力和肌肉疲软无力,故此维持正常的肌肉伸展性意义重大。

肌肉弹性:是指肌肉工作后产生收缩形变回复到初始状态的能力,表现肌肉血流在运动中供给状况及所能提高运动速度的能力。运动中骨骼肌的血流供给是否充分表现在其外形在2次收缩的间隙能否迅速恢复到原来的初始状态,即骨骼肌必须具备良好的弹性才能保证良好的血流供给,弹性下降会明显加速肌肉疲劳,并且如果骨骼肌弹性有问题其运动速度必定也会受到制约。

背景:远红外光波治疗可促进血液快速流动、强化各组织间物质能量交换和促进骨骼肌微损伤快速恢复等能力,其中远红外陶瓷微珠为近年来运动理疗、康复领域一种崭新的功能康复材料。

目的:以远红外陶瓷微珠为干预手段,验证其对骨骼肌损伤后肌肉伸展性、肌肉硬度和肌肉弹性物理3特性指标的影响。

方法:选择年龄18-21岁各体育专业确诊为股后肌群损伤的男性在校学生为试验对象,通过筛选最终纳入20名受试者,随机数字表法分为2组,分别进行普通远红外治疗仪(对照组)与远红外陶瓷微珠干预治疗(试验组),每组10名受试者,连续干预2周。利用无创肌肉检测系统采集治疗前与治疗后第3,7,14天的股后肌肉伸展性、肌肉硬度和肌肉弹性数据。

结果与结论:①试验组治疗后3,7,14 d的肌肉伸展性大于治疗前(P < 0.05,P < 0.01),且治疗后14 d已恢复至健侧水平(P > 0.05);对照组仅治疗后14 d的肌肉伸展性大于治疗前(P < 0.05),但仍低于健侧(P < 0.05);试验组治疗后不同时间点的肌肉伸展性大于对照组(P < 0.05,P < 0.01);②试验组治疗后3,7,14 d的肌肉硬度大于治疗前(P < 0.05,P < 0.01),且治疗后14 d已恢复至健侧水平(P > 0.05);对照组仅治疗后14 d的肌肉硬度大于治疗前(P < 0.05),但仍低于健侧(P < 0.05);试验组治疗后不同时间点的肌肉硬度大于对照组(P < 0.05,P < 0.01);③试验组治疗后3,7,14 d的肌肉弹性大于治疗前(P < 0.05,P < 0.01),且治疗后14 d已恢复至健侧水平(P > 0.05);对照组仅治疗后14 d的肌肉弹性大于治疗前(P < 0.05),但仍低于健侧(P < 0.05);试验组治疗后不同时间点的肌肉弹性大于对照组(P < 0.05,P < 0.01);④结果表明,远红外陶瓷微珠干预可提高肌肉的伸展性、弹性,降低肌肉硬度,促进损伤肌肉的恢复。

Abstract:

BACKGROUND: Far-infrared wave therapy can accelerate blood flow rapidly, strengthen the exchange of substance and energy among tissues, and promote the rapid recovery of musculoskeletal micro-injury. The far-infrared ceramic microsphere is a new functional rehabilitation material in the field of physical therapy and rehabilitation in recent years.

OBJECTIVE: To verify the therapeutic effectiveness of far-infrared ceramic microsphere intervention on muscle extensibility, stiffness, and elasticity after musculoskeletal injury.

METHODS: Male students aged 18-21 years who were diagnosed with posterior femoral muscle injury in each sports specialty were selected as test subjects. Twenty subjects were selected and randomly divided into two groups (n=10/group), and then underwent far-infrared therapeutic apparatus (control group) and far-infrared ceramic microsphere intervention treatment (trial group) for 2 consecutive weeks. A non-invasive muscle detection system was used to collect muscle extensibility, muscle stiffness, and muscle elasticity data before and 3, 7, and 14 days after treatment.

RESULTS AND CONCLUSION: (1) The muscle extensibility in the trial group at 3, 7, and 14 days after treatment was higher than that before treatment (P < 0.05, P < 0.01), and it had returned to the level of the healthy side at 14 days after treatment (P > 0.05). In the control group, the muscle extensibility at 14 days after treatment was higher than that before treatment (P < 0.05), but it was still lower than that of the healthy side (P < 0.05). The muscle extensibility at different time points in the trial group was higher than that in the control group (P < 0.05, P < 0.01). (2) The muscle stiffness in the trial group at 3, 7, and 14 days after treatment was higher than that before treatment (P < 0.05, P < 0.01), and at 14 days after treatment, it had returned to the level of the healthy side (P > 0.05). In the control group, the muscle stiffness at 14 days after treatment was higher than that before treatment (P < 0.05), but it was still lower than that of the healthy side (P < 0.05). The muscle stiffness at different time points in the trial group was higher than that in the control group (P < 0.05, P < 0.01). (3) The muscle elasticity in the trial group at 3, 7, and 14 days after treatment was higher than that before treatment (P < 0.05, P < 0.01), and at 14 days after treatment it had returned to the level of the healthy side (P > 0.05). In the control group, the muscle elasticity at 14 days after treatment was higher than that before treatment (P < 0.05), but it was still lower than that of the healthy side (P < 0.05). The muscle elasticity at different time points in the trial group was higher than that in the control group (P < 0.05, P < 0.01). (4) In summary, far-infrared ceramic microspheres can improve muscle extensibility and elasticity, reduce muscle stiffness and promote the recovery of muscle damage.
