The aim of this study was to compare the acute effects of compression contrast therapy (CT) and dry needling therapy (DN) on muscle tension (MT), muscle strength (Fmax), pressure pain threshold (PPT), and perfusion (PU) following fatigue of forearm muscles (e.g., flexor carpi radialis) in combat sports athletes. A single-blind randomized controlled trial was employed. Participants first underwent muscle fatigue induction, which involved sustaining an isometric handgrip at 60% of their maximum voluntary contraction in 5-second cycles. This was followed by exposure to one of the regenerative therapies. Forty-five participants were randomly assigned to one of three groups: CT/DN (n = 15), CT/ShDN (n = 15), and ShCT/DN (n = 15). The sham condition (Sh) involved a simulated version of the technique. Measurements were taken at four time points: (i) at rest; (ii) immediately after exercise that led to a state of fatigue; (iii) 5 minutes after therapy (PostTh5min); and (iv) 24 hours after therapy (PostTh24h). Each participant was exposed to one experimental condition and one control condition, thereby undergoing evaluation in two sessions. Significant differences between groups were found in MT during the PostTh5min ( = 0.005), as well as in PU during the PostTh5min ( < 0.001) and PU during the PostTh24h ( < 0.001). All groups showed significant improvements at 5 minutes post-therapy compared to immediately post-muscle fatigue. As conclusions, CT/DN seems to be significantly better for enhancing MT and PU after 5 minutes of muscle fatigue induction. Using either CT, DN, or both combined is recommended to enhance the recovery of muscle functionality and properties, favoring recovery and potentially speeding up performance enhancement.
本研究旨在比较压缩对比疗法（CT）和干针疗法（DN）对格斗运动运动员前臂肌肉（如桡侧腕屈肌）疲劳后肌肉张力（MT）、肌肉力量（Fmax）、压力疼痛阈值（PPT）和灌注（PU）的急性影响。采用单盲随机对照试验。参与者首先进行肌肉疲劳诱导，即在 5 秒周期内以 60%的最大自主收缩力进行等长握力。随后进行再生治疗之一。45 名参与者被随机分配到三个组之一：CT/DN（n = 15）、CT/ShDN（n = 15）和 ShCT/DN（n = 15）。Sh 条件（Sh）涉及技术的模拟版本。在四个时间点进行测量：（i）在休息时；（ii）在导致疲劳的运动后立即；（iii）治疗后 5 分钟（PostTh5min）；和（iv）治疗后 24 小时（PostTh24h）。每个参与者都暴露于一种实验条件和一种对照条件，从而在两次会议中进行评估。在 PostTh5min 时，MT 之间存在显著差异（ = 0.005），在 PostTh5min 时和 PostTh24h 时，PU 之间存在显著差异（ < 0.001）。与肌肉疲劳后立即相比，所有组在治疗后 5 分钟时均显示出显著改善。因此，CT/DN 似乎在肌肉疲劳诱导后 5 分钟时对增强 MT 和 PU 非常有效。建议使用 CT、DN 或两者结合来增强肌肉功能和特性的恢复，有利于恢复并可能加速性能提升。
