The purpose of this study was to compare the effects of dry needling (DN) intervention on the responses of muscle tone, stiffness, and elasticity, as well as power, pressure pain thresholds, and blood perfusion of the flexor carpi radialis muscle in mixed martial arts (MMA) athletes. Thirty-two trained/developmental men MMA fighters (25.5±4.5 years; 24.5±3 body mass index) participated in a randomized crossover study. Participants underwent a single intervention, receiving both DN and placebo. Laser Doppler flowmetry measured blood perfusion, while a myotonometer assessed the mechanical characteristics of muscle tone, stiffness, and elasticity of the flexor carpi radialis muscle. Pressure pain thresholds (PPT) were measured using an algometer, and maximal forearm muscle force was measured using a hand dynamometer. Outcomes were assessed at baseline, immediately after, and 24 hours and 48 hours post-intervention. A two-way repeated-measures ANOVA revealed significant interaction for all outcomes: perfusion unit (p<0.001), muscle tone (<0.001), stiffness (<0.001), elasticity (<0.001), PPT (<0.001) and maximal forearm muscle force (<0.001). The current study suggests that a single session of DN enhances muscle recovery, increases muscle strength, and improved PPT in MMA athletes. These positive adaptations appear to last up to 48 hours in some variables.
本研究的目的是比较干针疗法（DN）干预对综合格斗（MMA）运动员桡侧腕屈肌的肌张力、僵硬度、弹性以及力量、压力疼痛阈值和血液灌注反应的影响。32名训练有素/处于发展阶段的男性MMA格斗选手（25.5±4.5岁；体重指数24.5±3）参与了一项随机交叉研究。参与者接受了单次干预，包括接受DN和安慰剂治疗。激光多普勒血流仪测量血液灌注，而肌动计评估桡侧腕屈肌的肌张力、僵硬度和弹性的力学特性。使用压力痛觉计测量压力疼痛阈值（PPT），并使用握力计测量前臂肌肉最大力量。在基线、干预后即刻、干预后24小时和48小时评估结果。双向重复测量方差分析显示所有结果均存在显著交互作用：灌注单位（p<0.001）、肌张力（<0.001）、僵硬度（<0.001）、弹性（<0.001）、PPT（<0.001）和前臂肌肉最大力量（<0.001）。当前研究表明，单次DN治疗可促进MMA运动员的肌肉恢复、增加肌肉力量并改善PPT。这些积极的适应性变化在某些变量中似乎可持续长达48小时。
