热红外成像来检测迟发性肌肉酸痛
Summary
本次调查的目的是评估是否使用红外热成像摄像机是一个有效的检测和定量运动后肌肉酸痛工具。
Abstract
迟发性肌肉酸痛（DOMS），又称运动引起的肌肉损伤（EIMD），通常是曾长时间的身体活动，并开始练习1-4意外回合的个人经历，但也可以发生在运动员超出正常范围内行使他们的培训5。痛苦的现象与此相关的症状范围从轻微的肌肉压痛，严重衰弱疼痛 1,3,5 。这些症状和相关的不适，增加第一个24小时内终止行使，及24至72小时后练习1,3之间的峰的强度。出于这个原因，DOMS的是经常运动损伤最常见的形式，可以影响一个人的表现，并成为许多1,4恐吓之一。
在过去的三十年，DOMS的现象已经获得了相当数量的其中包括研究人员和专家，在运动生理学，体育，和康复领域 6的兴趣。已有各种调查这种痛苦发生在其潜在的机制，治疗干预，并1-5,7-12预防战略方面的研究发表。然而，这是显而易见的，从文学，DOMS不是一件容易的的病理量化，因为有一个变异之间的测量工具和方法，用来量化这种情况下6。这是显而易见的，一个最好的评价措施DOMS的，这使得它难以核实是否在一个特定的干预确实有助于减少这种类型的疼痛或不相关的症状一直没有达成协议。因此，可以看出DOMS的有点含糊，因为许多研究取决于测量疼痛采用视觉模拟评分（VAS）10,13-15，这是一种主观的，而不是一个客观的衡量。即使针肌肉活检，myofibre蛋白质的血药浓度可能会考虑一些大的变化，在这些血蛋白 6金标准已记录在 6,16，除了有时与微创技术相关的高风险。
因此，在目前的调查中，我们测试了皮肤的热红外（IR）成像行使肌肉以上技术检测相关的肌肉酸痛。红外热成像已被使用，被发现在自1950年的17个不同类型的疾病和感染检测成功。但令人惊讶的是，附近没有完成DOMS和皮肤温度的变化。本次调查的主要目的是使用这种安全和非侵入性技术研究在DOMS的变化。
Protocol
1。演习本实验的兴趣肌肘屈肌（肱二头肌）。 肌力测定每个参与者能够给每一个人一个合适的电阻。这是由测试其电阻最大（RM）的每个参与者。 为了测试的RM，我们用应变仪与计算机通过一个BIOPAC（DA – 100C）生物电放大器模块（BIOPAC系统，Goleta，CA）来衡量肌肉力量接口设备。该模块连接到MP – 100的模拟数字转换器的采样频率为1000赫兹每秒，分辨率24位（图10）。 应…
Discussion
本次调查的主要目的是评估的热红外成像检测和测量，剧烈运动后肌肉酸痛的实用性，而且，我们的结果表明，红外成像可以为检测DOMS的有效技术，特别是在第一次24小时行使，。这并不奇怪，Pennes 18提供了一个非常详细的模型热流从肌肉四肢皮肤。该模型预测，在深层组织如肌肉的热量可以通过导电的热交换进入血液和皮肤进入消退。当肌肉运动，显然，巨大的热量是在肌肉中的肌纤?…
