在过去的几个月里，我一直在写作novel therapies marketed to athletes改善受伤的恢复。在本文中，我们将考虑相对于我在最近写的东西，低级激光治疗（LLLT）的待遇，这些升级更像是恢复工具的兴起而不是伤害。
As you may recall, LLLT leverages photobiomodulation to affect the body’s tissues. The theory behind this is that when the light of specific wavelengths penetrates the tissues, it causes changes within the cells to produce a result. In the case of LLLT, research demonstrated those results were at best modest, with evidence only to support its use for chronic Achilles tendinopathy.
While LLLT utilizes light of a short wavelength, red light therapy uses visible light with a much longer wavelength and is suggested to have very different effects. Several LED red light panels manufacturers claim that their use can impact everything from sleep quality to skin appearance to sexual function to athletic performance and more.
These panels are quite costly, ranging anywhere from hundreds to thousands of dollars, so the discerning athlete would be wise to wonder whether this is an investment that can be expected to pay off with any of the promised benefits.
红灯疗法基础知识
基于红光疗法如何与LLLT类似的理论。用红光疗法，将较长的波长可见和近红外光施加到皮肤上。在穿透细胞后，线粒体吸收并具有它们的功能，以改变以产生更多的ATP，能量分子用于细胞的功能。这是假设，以提高锻炼后的性能和耐久性而不是它。
支持红光疗法制造商制造商制造商制造的大部分索赔的证据非常稀缺或弱。但是，有关使用此种方式的运动表现，有一个相当强劲的证据。2016年的一篇评论文章总结了大部分证据。[一世]
第一组研究评估了红光疗法，以改善在施加到上肢时努力后的性能或恢复。研究评估了肌肉损伤的性能和生化标志物的客观标志性和肌肉疼痛的主观报告。虽然该组的一些研究报告了红光疗法细胞损伤的生化标志物的改善，但这种发现与改善性能的任何客观措施没有任何相关的措施，也没有任何报告的延迟发病肌肉酸痛（DOM）的改进。这组10中的一项研究报告了略有的性能改善。
另一组研究评估红光therapy applied to the lower extremities, the results were very inconsistent, with some studies finding improvements in performance and others not. Similarly, there was varying reporting of improvements in subjective reports of discomfort associated with DOMS and no findings to suggest any changes in biochemical markers of cellular damage in these athletes.
最终的研究组寻求确定红光疗法是否对蜂窝功能产生更长持久的影响。在这些论文中，研究人员报告了旨在评估红光疗法可以随时间改变蜂窝功能的实验，以便通过导致肌肉组织建筑的改善和处理氧化应激的能力来改变运动员。
该理论是，长期暴露于红光疗法可能上调特定遗传途径的表达改变了两种特征。再一次，结果非常不一致。一些研究表明，随着时间的推移报告了肌肉架构的变化，但这些变化与任何绩效福利无关。没有研究发现组织处理氧化应激的能力的任何改进。
目前的红灯疗法结论
似乎基于对PhotobioModulation和特异性红光疗法所知的，它仍然是一个有趣但非常多的未经证实的技术。虽然显然可以批量生产和市场的能力，但这些设备的证据仍然缺乏。
This is another example of a technology with significant theoretical benefits but no proven clinical benefits to date. That may change as additional studies are done, new applications are developed, or the technology is modified somehow. Still, red light therapy remains a novelty for now and is not worth the significant investment.
Train hard, train healthy.
