该研究旨在评估干针(DN)治疗对生物力学特性的直接影响,肌肉力量,灌注,和具有潜在触发点的腓肠肌的压力疼痛阈值。20名混合武术运动员(MMA)随机分为两组:实验(eDN,n=10)和假(qDN,n=10)用真针或qazi针进行一次DN。测量是在休息时进行的,DN后1-5分钟(Post1-5min)和DN后24h(Post24h)。DN显著增加肌肉灌注(后1-5min和后24h,p<0.001),降低了它的音调(Post1-5min和Post24h,p<0.001)和刚度(后1-5分钟,p<0.05;24小时后,p<0.001),并提高了其弹性(Post1-5min和Post24h,p<0.001)。DN还导致压力痛阈值显着增加(Post1-5min,p<0.001;24h后,p<0.05)和肌肉力量(24h后,p<0.01)。DN会话增加了血液灌注,改善了腓肠肌的生物力学特性,从而提高了肌肉力量。DN还具有镇痛作用。这些效果保持在24小时,这表明DN可以促进MMA运动员运动后的肌肉恢复。
The study aimed to evaluate the immediate effects of a dry needling (DN) therapy session on biomechanical properties, muscle power, perfusion, and pressure pain threshold of the gastrocnemius muscle with latent trigger points. Twenty mixed martial arts athletes (MMA) were randomly divided into two groups: experimental (eDN, n = 10) and sham (qDN, n = 10) to undergo one session of DN either with a real or a qazi needle. The measurements were taken at rest, 1-5 minutes after the DN (Post1-5min) and 24h after the DN (Post24h). DN significantly increased the muscle perfusion (Post1-5min and Post24h, p < 0.001), reduced its tone (Post1-5min and Post24h, p < 0.001) and stiffness (Post1-5min, p < 0.05; Post24 h, p < 0.001), and improved its elasticity (Post1-5min and Post24h, p < 0.001). DN also caused a significant increase in pressure pain threshold (Post1-5min, p < 0.001; Post24h, p < 0.05) and in muscle power (Post24h, p < 0.01). The DN session increased the blood perfusion and improved the biomechanical properties of the gastrocnemius muscle, which led to improved muscle power. The DN also had an analgesic effect. These effects were maintained at 24 h, which suggests that DN could facilitate muscle recovery in a post-exercise period of MMA athletes.
