In recent years, it has been demonstrated that photobiomodulation therapy (PBMT) using low-level laser therapy and/or light-emitting diode therapy combined to static magnetic field (sMF) has ergogenic effects, improving muscular performance and accelerating postexercise recovery. However, many aspects related to these effects and its clinical applicability remain unknown. Therefore, the aim of this project is to evaluate the ergogenic effects of PBMT/sMF in detraining after a strength-training protocol.
The study will be a randomised, triple-blind, placebo-controlled clinical trial. Healthy male volunteers will be randomly distributed into four experimental groups: PBMT/sMF before training sessions + PBMT/sMF during detraining, PBMT/sMF before training sessions + placebo during detraining, placebo before training sessions + PBMT/sMF during detraining and placebo before training sessions + placebo during detraining. Strength-training sessions will be carried out over 12 weeks, and the detraining period will occur during the 4 weeks after. The muscular strength and the structural properties of quadriceps will be analysed.
This study was approved by the Research Ethics Committee of Nove de Julho University. The results from this study will be disseminated through scientific publications in international peer-reviewed journals and presented at national and international scientific meetings.

近年来，已经证明，低水平激光疗法和/或发光二极管疗法联合静磁场（sMF）的光生物调节疗法（PBMT）具有运动表现增强作用，可提高肌肉性能并加速运动后的恢复。然而，与这些效果及其临床适用性相关的许多方面仍不清楚。因此，本项目的目的是评估在力量训练方案后的减训期内，PBMT/sMF 的运动表现增强作用。
这项研究将是一项随机、三盲、安慰剂对照的临床试验。健康的男性志愿者将被随机分为四组实验组：训练前 PBMT/sMF + 减训期 PBMT/sMF、训练前 PBMT/sMF + 减训期安慰剂、训练前安慰剂+减训期 PBMT/sMF 和训练前安慰剂+减训期安慰剂。力量训练课程将持续 12 周，减训期将在 4 周后进行。将分析股四头肌的肌肉力量和结构特性。
这项研究得到了诺瓦德朱尼奥大学研究伦理委员会的批准。本研究的结果将通过国际同行评议期刊上的科学出版物传播，并在国内和国际科学会议上展示。
