文题释义:
运动压缩服:运动压缩服是指给予人体身体一个外在的压力,并利用压力差压缩身体组织以及其下的血管,用以改善静脉的回流、加速血流速度、提升氧气输送至肌肉的能力,并减少周边水肿。随着全民健身运动的兴起,各种压缩装备也随之兴起,如压缩腿套、压缩袜、压缩衣、压缩裤、压缩护臂等。以最常用的压缩腿套为例,其本质就是口径较小的高弹性编织面料,这样就可以将其充分包裹束缚住小腿,从而发挥作用。
延迟性肌肉酸痛(DOMS):是指机体从事大运动量,特别是开始一项新运动、运动项目改变或运动强度突然增加后一段时间内出现的肌肉酸痛现象,它是一种特殊类型的运动性肌肉疲劳,可能是产生超量恢复的基础条件。延迟性肌肉酸痛一般出现在运动后12-24 h,24-48 h达高峰,3-7 d可自行缓解并消失。延迟性肌肉酸痛的疼痛不同于肌肉拉伤扭伤等急剧性疼痛,其开始于肌肉远端后扩散至整块肌肉,其在安静状态时不产生自发的慢性疼痛,只有当肌肉进行收缩、被牵张或触诊等机械刺激时,才会诱发产生疼痛的感觉,因此延迟性肌肉酸痛又称为触压疼。
摘要
背景
:离心运动会诱发延迟性肌肉酸痛,促使血液中的肌酸激酶上升,而肌酸激酶的上升是用来评估肌肉损伤情形的重要指标;穿压缩裤可减少跑步时的能量消耗,但穿压缩裤对减缓延迟性肌肉酸痛有无效益至今无定论。
目的:分析穿压缩腿套进行下坡跑运动对运动后诱发肌肉损伤及动脉硬化指标——踝臂脉波传导速率的影响,从而确认穿压缩裤是否能起到降低肌肉损伤程度的功效。
方法:选取15位无健身习惯的男性大学生,采取随机方式于运动中单脚穿压缩腿套,通过接受一次70%保留心跳率强度,坡度为-10°的30 min跑步机上的下坡跑运动,并在下坡跑运动前及运动后24 h分别进行肌酸激酶、踝臂脉波传导率、酸痛指数、主动关节活动度、肌肉肿胀围、最大自主等长收缩肌力及超声波股直肌肌肉厚度等指标测试。
结果与结论:①不论是试验脚还是控制脚,下坡跑24 h血液中肌酸激酶及踝臂脉波传导率皆显著高于前测,但两脚之间的踝臂脉波传导率无差异;②无论是试验脚还是控制脚,运动后24 h运动自觉努力程度量表值、50%最大自主等长收缩力酸痛指数(目测类比评分)及酸痛指数值皆显著高于前测,但同一时间点比较,试验脚及控制脚3个指标值无显著差异;③肌肉肿胀围、主动关节活动度、最大自主等长收缩力及股直肌厚度皆不受组别因素(试验脚与控制脚)及运动前后时间因素交互作用影响,但股直肌厚度及肌肉肿胀围在运动后24 h显著高于运动前,而主动关节活动度及最大自主等长收缩力在运动后24 h显著低于运动前;④结果说明,穿压缩腿套无法减缓下坡跑运动所引起的肌肉损伤及随后的延迟性肌肉酸痛与暂时性的踝臂脉波传导率上升现象。

Abstract:

BACKGROUND: Centrifugal exercise can induce delayed onset of muscle soreness and increase the level of creatine kinase in the blood. Increased creatine kinase level is an important indicator for evaluating muscle injury. Wearing compression leg cuffs can reduce energy consumption during running. However, whether it can delay the onset of muscle soreness remains controversial.
OBJECTIVE: To investigate the effect of downhill running with compression leg cuffs on muscle injury and arteriosclerosis index-ankle-brachial pulse wave conduction velocity and provide evidence to validate whether compression leg cuffs can reduce the degree of muscle injury.
METHODS: Fifteen male college students without fitness habits were randomly selected to wear compression leg cuffs on one foot during exercise. They were subjected to a 30-minute downhill running on a treadmill with a 70% heart rate intensity and a slope of -10°. Creatine kinase, ankle-brachial pulse wave, soreness index, active joint activity, muscle swelling, maximum isometric contraction muscle strength and ultrasonic rectus femoris muscle thickness were measured before and 24 hours after downhill running.
RESULTS AND CONCLUSION: Creatine kinase in blood and ankle-brachial pulse wave conduction velocity after 24 hours of downhill running were significantly higher than those of the pre-test, but there were no differences in these two indices between two feet. Rating of Perceived Exertion, 50% maximal autonomous isometric contraction force pain index (Visual Analogue Scale) and soreness index at 24 hours after exercise were significantly higher than those of the pre-test at both feet. There were no significant differences in the three indexes between two feet at the same time points. Muscle swelling circumference, active joint mobility, maximal autonomous isometric contraction force and rectus femoris thickness were not affected by the interaction of group factors (test foot and control foot) and time factors (pretest and 24 hours posttest). However, rectus femoris thickness and muscle swelling circumference at 24 hours after exercise were significantly higher than those before exercise. The active joint activity and maximal autonomous isometric contraction force at 24 hours after exercise were significantly lower than those before exercise. In summary, wearing compression leg cuffs cannot reduce the muscle injury caused by downhill running and the subsequent delayed muscle soreness and temporary increase in ankle-brachial pulse wave conduction velocity.
