This study aimed to investigate the influence of endurance running training associated with PBM on endurance performance variables and muscle soreness in untrained men. Thirty untrained men were distributed randomly into a placebo (PLA) group and photobiomodulation group (PBMG) and they performed 8 weeks of running training. The PBMG had the PBM performed before all training sessions. The PBM was applied using LED equipment with 56 diodes of red light (660 nm) and 48 diodes of infrared light (850 nm). The application was performed in 5 points per leg, with a dose of 60 J at each point and a total energy delivered per leg of 300 J. Peak running velocity, time limit tests and 5-km performance were assessed pre and post-training; muscle soreness was evaluated before all training sessions. The V increased and 5-km running time (t) decreased ( < 0.001) in both groups. In addition, the magnitude based-inference analysis showed a effect on V and t and for PBMG compared to PLA group. Furthermore, there was a moderate ES of 0.82 on attenuation in muscle soreness in the third week of endurance running training. Therefore, although the magnitude-based inference analysis demonstrated a effect on V and t and for PBMG compared to PLA group and a moderate ES on attenuation in muscle soreness in the last weeks of endurance running training, no significant difference were found between PBMG and PLA interventions.
本研究旨在调查与光生物调节（PBM）相关的耐力跑训练对未经训练男性的耐力表现变量和肌肉酸痛的影响。30名未经训练的男性被随机分为安慰剂（PLA）组和光生物调节组（PBMG），他们进行了8周的跑步训练。PBMG在所有训练课程之前进行PBM。使用具有56个红光二极管（660纳米）和48个红外光二极管（850纳米）的LED设备进行PBM。每条腿在5个点进行照射，每个点的剂量为60焦耳，每条腿传递的总能量为300焦耳。在训练前后评估峰值跑步速度、限时测试和5公里表现；在所有训练课程之前评估肌肉酸痛。两组的V均增加，5公里跑步时间（t）减少（<0.001）。此外，基于幅度的推断分析显示，与PLA组相比，PBMG对V和t有影响。此外，在耐力跑训练的第三周，肌肉酸痛减轻的效应量为中等的0.82。因此，尽管基于幅度的推断分析表明，与PLA组相比，PBMG对V和t有影响，并且在耐力跑训练的最后几周肌肉酸痛减轻的效应量为中等，但在PBMG和PLA干预之间未发现显著差异。
