This study aimed to analyze PBMT effects on futsal player's performance and recovery in a non-controlled field environment. It is a randomized, triple-blinded, placebo-controlled, crossover clinical trial. The research included six professional athletes and in each match phototherapy treatments were performed before matches (40 minutes), blood samples were collected before treatments, and samples immediately after the end of the matches and 48 h after. Furthermore, videos were analyzed to quantify the time athletes spent on the pitch and the distance they covered. PBMT was performed at 17 sites of each lower limb (40 mins before matches), employing a cluster with 12 diodes (4 laser diodes of 905 nm, 4 LEDs of 875 nm, and 4 LEDs of 640 nm, 30 J per site). The performance of the athlete could be quantified considering the time on the pitch and the distance covered; the biochemical markers evaluated were creatine kinase, lactate dehydrogenase, blood lactate, and oxidative damage to lipids and proteins. PBMT significantly increased the time of staying in the pitch and a significant improvement in all the biochemical markers evaluated. No statistically significant difference was found for the distance covered. Pre-exercise PBMT can enhance performance and accelerate recovery of high-level futsal players.
本研究旨在分析非受控场地环境下,低强度脉冲式激光疗法(PBMT)对五人制足球运动员表现和恢复情况的影响。这是一项随机、三盲、安慰剂对照的交叉临床试验。该研究纳入了六名职业运动员,在每场比赛前(40分钟)进行光疗治疗,在治疗前、比赛结束后即刻以及48小时后采集血样。此外,还对视频进行分析,以量化运动员在球场上的时间和跑动距离。PBMT在每个下肢的17个部位进行(比赛前40分钟),使用一个包含12个二极管的集群(4个905纳米的激光二极管、4个875纳米的发光二极管和4个640纳米的发光二极管,每个部位30焦耳)。可以通过考虑运动员在球场上的时间和跑动距离来量化其表现;评估的生化指标包括肌酸激酶、乳酸脱氢酶、血乳酸以及脂质和蛋白质的氧化损伤。PBMT显著增加了运动员在球场上的停留时间,并且所有评估的生化指标都有显著改善。在跑动距离方面未发现统计学上的显著差异。运动前进行PBMT可以提高高水平五人制足球运动员的表现并加速其恢复。
