Photobiomodulation therapy (PBMT) has recently been indicated as a potential therapeutic strategy in diverse health and sports contexts. However, its efficacy on muscle performance in female futsal players remains unknown. The purpose of this study was to investigate the dose-response effect of PBMT on muscle performance in female futsal players.
In a crossover design, fifteen female futsal athletes (age: 18-30 years) were randomized to receive 1 of 4 PBMT conditions (placebo, 300, 900, and 1260 J [J]) on four occasions, separated by a 2-wk washout period. PBMT treatments were applied on the quadriceps muscle of both legs using a device containing 200 light-emitting diodes (LEDs), immediately before the following tests: countermovement jump (CMJ) (i.e., flight time as indicator of muscle power), maximum voluntary isometric contraction (MVIC) for the leg extension exercise (i.e., muscle strength), and 3 sets of repetitions-to-failure (i.e., local muscular endurance) for the 45° leg press exercise, with recording of rating of perceived exertion (RPE) after each set. The fatigue index was determined by the number of repetitions between sets 1 and 3.
No significant differences were found between the PBMT conditions for the maximum number of repetitions (p = 0.899), RPE (time p < 0.0001; interaction p = 0.653), fatigue index (p = 0.835), muscle power (p = 0.789), and isometric peak and mean torque (p = 0.776 and 0.537, respectively).
Different doses of acute PBMT with LEDs do not improve muscle performance (endurance, power, and strength) and RPE in female futsal players.
光生物调节疗法（PBMT）最近已被视为在各种健康和运动情境中的一种潜在治疗策略。然而，其对女子五人制足球运动员肌肉性能的功效仍不明确。本研究的目的是调查PBMT对女子五人制足球运动员肌肉性能的剂量反应效应。
采用交叉设计，15名女子五人制足球运动员（年龄：18 - 30岁）被随机分为四组，分别接受4种PBMT条件（安慰剂、300、900和1260焦耳[J]）中的一种，共进行四次，每次之间间隔2周的洗脱期。使用包含200个发光二极管（LED）的设备对双腿的股四头肌进行PBMT治疗，在以下测试前即刻进行：反向移动跳跃（CMJ）（即飞行时间作为肌肉力量指标）、腿部伸展运动的最大自主等长收缩（MVIC）（即肌肉力量）以及45°腿举运动的3组重复至力竭（即局部肌肉耐力），每组后记录主观用力程度（RPE）。疲劳指数由第1组和第3组之间的重复次数确定。
在PBMT各条件之间，重复次数最大值（p = 0.899）、RPE（时间p < 0.0001；交互作用p = 0.653）、疲劳指数（p = 0.835）、肌肉力量（p = 0.789）以及等长峰值和平均扭矩（分别为p = 0.776和0.537）均未发现显著差异。
不同剂量的急性LED - PBMT并不能改善女子五人制足球运动员的肌肉性能（耐力、力量和强度）以及RPE。
