The aim of the present study was to investigate the effectiveness of photobiomodulation therapy (PBMT) on muscle recovery based on inflammation (interleukin-10 [IL-10]; tumor necrosis factor-α [TNFα]), muscle damage markers (creatine kinase [CK]; lactate dehydrogenase [LDH]), delay onset muscle soreness (DOMS), and countermovement jump performance (CMJ) after two sprint interval training (SIT) sessions compared with a placebo condition (part-I), as well as to compare the effectiveness of PBMT with active recovery (AR) and cold-water immersion (CWI) (part-II). Part-I was conducted as a double-blind, randomized and placebo-controlled study and part-II as a parallel-group study. Thirty-six men participated in the studies (12 participants in part-I and 36 participants in part-II). Volunteers performed two SITs interspaced by 24-h (SIT and SIT) to mimic the effect of accumulating 2 consecutive days of SIT. In part-I, only after SIT, PBMT [Total energy: 600J (300J per leg in 5 spots); wavelength: 660-850 nm] or placebo interventions were performed, while in part-II PBMT (part-I data), AR (15-min; 50% of the maximal aerobic power), or CWI (10-min; 10°C) were carried out, also after SIT. Blood samples were collected before (i.e., baseline), and 0.5, 1, 24, 48, and 72-h after SIT, while CMJ and DOMS were measured before, 24, 48, and 72-h after SIT. In part-I, there were no interactions between PBMT and placebo conditions for any blood markers ( ≥ 0.313), DOMS ( = 0.052), and CMJ ( = 0.295). However, an effect of time was found with increases in LDH, CK, and IL-10 ( ≤ 0.043) as well as a decrease in DOMS at 72-h compared with 24-h ( = 0.012). In part-II, there were no interactions between the PBMT, AR, and CWI groups for any markers at the same moments ( ≥ 0.189) and for the peak and integral values ( ≥ 0.193), for DOMS ( = 0.314) and CMJ ( = 0.264). However, an effect of time was found with an increase in CK and IL-10 ( = 0.003), while DOMS decreased at 48 and 72-h compared with 24-h ( = 0.001). In summary, PBMT had no effect on inflammation, muscle damage, CMJ performance, or DOMS after two consecutive sprint interval training sessions compared to placebo, CWI, and AR strategies.
本研究的目的是调查光生物调节疗法（PBMT）对基于炎症（白细胞介素-10 [IL-10]；肿瘤坏死因子-α [TNFα]）、肌肉损伤标志物（肌酸激酶 [CK]；乳酸脱氢酶 [LDH]）、延迟性肌肉酸痛（DOMS）以及与安慰剂对照条件相比，两次冲刺间歇训练（SIT）后反向运动跳跃表现（CMJ）的肌肉恢复的有效性（第一部分），并比较PBMT与主动恢复（AR）和冷水浸泡（CWI）的有效性（第二部分）。第一部分作为双盲、随机和安慰剂对照研究进行，第二部分作为平行组研究进行。三十六名男性参与了研究（第一部分12名参与者，第二部分36名参与者）。志愿者进行了两次间隔24小时的SIT（SIT和SIT），以模拟连续两天进行SIT的累积效果。在第一部分中，仅在SIT后进行PBMT [总能量：600焦耳（每条腿在5个部位各300焦耳）；波长：660 - 850纳米] 或安慰剂干预，而在第二部分中，同样在SIT后进行PBMT（第一部分数据）、AR（15分钟；最大有氧功率的50%）或CWI（10分钟；10°C）。在SIT前（即基线）以及SIT后0.5、1、24、48和72小时采集血样，同时在SIT前、SIT后24、48和72小时测量CMJ和DOMS。在第一部分中，对于任何血液标志物（≥0.313）、DOMS（=0.052）和CMJ（=0.295），PBMT与安慰剂对照条件之间均无相互作用。然而，发现了时间效应，与24小时相比，LDH、CK和IL-10升高（≤0.001），且72小时时DOMS降低（=0.012）。在第二部分中，在相同时间点（≥0.189）以及峰值和积分值（≥0.193）、DOMS（=0.314）和CMJ（=0.264）方面，PBMT、AR和CWI组之间对于任何标志物均无相互作用。然而，发现了时间效应，CK和IL-10升高（=0.003），而与24小时相比，48和72小时时DOMS降低（=0.001）。总之，与安慰剂、CWI和AR策略相比，连续两次冲刺间歇训练后，PBMT对炎症、肌肉损伤、CMJ表现或DOMS没有影响。
