To investigate the recovery of male water polo athletes applying full body photobiomodulation therapy (PBMT) regarding inflammation and muscle damage markers, testosterone and cortisol hormonal responses, heart rate variability (HRV), maximal voluntary contraction, and squat jump (SJ) after official water polo matches. PBMT has been applied locally on specific muscle groups to induce faster recovery and improve the performance of athletes and nonathletes. However, many sports modalities require movement of the whole body, and a full body PBMT could be more adequate to irradiate large muscle areas homogeneously and faster. In a randomized, parallel, and double-blinded design, 13 athletes (whole team) aged 18 years attended the study and were allocated into two groups: PBMT (dose of 6.9 J/cm, irradiance of 46.17 mW/cm, 5 min irradiation) and placebo treatment. The study was conducted during the 2019 Brazilian under 20 water polo championship. All athletes were assessed by blood samples and neuromuscular evaluation. Immediately after each match, all athletes received PBMT (effective or placebo). No significant interactions (raw values and percentage related to baseline) were observed for testosterone and cortisol, tumor necrosis factor-alpha, interleukin-6, creatine kinase concentration, maximal isometric voluntary contraction, SJ test, and HRV. Only an isolated interaction (decrease) was found for lactate dehydrogenase (LDH) response after the first match ( = 0.004, post-hoc = 0.038). The parameters of the full body PBMT of this study did not induce faster recovery of inflammatory, muscle damage (excepting LDH), testosterone, cortisol, HRV, and neuromuscular responses during repeated days of water polo matches.
为了研究男性水球运动员在正式水球比赛后应用全身光生物调节疗法（PBMT）对炎症和肌肉损伤标志物、睾酮和皮质醇激素反应、心率变异性（HRV）、最大自主收缩以及深蹲跳（SJ）恢复情况的影响。PBMT已被局部应用于特定肌肉群，以促进运动员和非运动员更快恢复并提高其表现。然而，许多运动方式需要全身运动，全身PBMT可能更适合均匀且快速地照射大面积肌肉。在一项随机、平行、双盲设计中，13名18岁的运动员（整个团队）参与了该研究，并被分为两组：PBMT组（剂量为6.9 J/cm，辐照度为46.17 mW/cm，照射5分钟）和安慰剂治疗组。该研究在2019年巴西20岁以下水球锦标赛期间进行。所有运动员均通过血液样本和神经肌肉评估进行评估。每场比赛结束后，所有运动员立即接受PBMT（有效或安慰剂）。在睾酮和皮质醇、肿瘤坏死因子-α、白细胞介素-6、肌酸激酶浓度、最大等长自主收缩、SJ测试和HRV方面，未观察到显著的相互作用（原始值和与基线相关的百分比）。仅在第一场比赛后发现乳酸脱氢酶（LDH）反应存在孤立的相互作用（降低）（P = 0.004，事后检验P = 0.038）。本研究中全身PBMT的参数在水球比赛的连续几天中并未诱导炎症、肌肉损伤（LDH除外）、睾酮、皮质醇、HRV和神经肌肉反应更快恢复。
