Recent studies have shown that the extramuscular connective tissue (ECT) is thickened and stiffened in delayed onset muscle soreness (DOMS). However, contrarily to the normal population, severe DOMS is rare in athletes or highly trained individuals. The present randomized, controlled trial therefore aimed to investigate pain as well as microcirculation and stiffness of the ECT and the erector spinae muscle following submaximal eccentric trunk extension exercise not causing DOMS. The effect of manual treatment by a therapist (myofascial release; MFR) on these parameters was to be studied. Trained healthy participants (n = 21; 31.3 ± 9.6 years; > 4 h exercise per week) performed submaximal eccentric exercise of the trunk extensors. One group was manually treated (n = 11), while the other group (n = 10) received placebo treatment with sham laser therapy. Stiffness of the ECT and the erector spinae muscle (shear wave elastography), microcirculation (white light and laser Doppler spectroscopy), palpation pain (100 mm visual analogue scale, VAS) and pressure pain threshold (indentometry, PPT) were assessed before (t), 24 h (t) and 48 h (t) after conditions. Erector spinae muscle stiffness increased after eccentric exercise from t to t (0.875 m/s) and from t to t (0.869 m/s). After MFR, erector spinae muscle stiffness decreased in contrast to placebo treatment at t (-0.66 m/s), while ECT stiffness remained unchanged. Oxygen saturation increased (17-20.93%) and relative haemoglobin decreased (-9.1 - -12.76 AU) after eccentric exercise and MFR differed from placebo treatment at t (-3.71 AU). PPT differed after MFR from placebo treatment at t (20.69 N/mm), while VAS remained unchanged. Multiple linear regression showed that ECT stiffness and group membership predicted erector spinae muscle stiffness. MFR could have a positive effect on pain, microcirculation and muscle stiffness after submaximal eccentric exercise, suggesting better recovery, which needs to be confirmed by future work.
最近的研究表明，延迟性肌肉酸痛（DOMS）患者的肌肉外结缔组织（ECT）增厚和变硬。然而，与正常人群相反，运动员或高训练量人群中很少出现严重的 DOMS。因此，本随机对照试验旨在研究亚极量离心性躯干伸展运动后，ECT 和竖脊肌的疼痛、微循环和僵硬情况，这种运动不会引起 DOMS。研究人员还研究了治疗师（肌筋膜松解术；MFR）手法治疗对这些参数的影响。21 名（31.3±9.6 岁；每周运动时间＞4 小时）受过训练的健康参与者进行亚极量离心性躯干伸展运动。一组接受手法治疗（n=11），另一组（n=10）接受假激光治疗的安慰剂治疗。治疗前（t）、24 小时（t）和 48 小时（t）时，采用剪切波弹性成像评估 ECT 和竖脊肌僵硬度、白光和激光多普勒光谱评估微循环、100mm 视觉模拟量表（VAS）评估触诊疼痛、压痕仪评估压力疼痛阈值（PPT）。离心运动后，竖脊肌僵硬度从 t 时增加至 t 时（0.875 m/s）和 t 时（0.869 m/s）。与安慰剂治疗相比，MFR 后竖脊肌僵硬度在 t 时下降（-0.66 m/s），而 ECT 僵硬度保持不变。与安慰剂治疗相比，离心运动和 MFR 后氧饱和度增加（17-20.93%），相对血红蛋白减少（-9.1--12.76 AU），t 时差异明显（-3.71 AU）。MFR 后与安慰剂治疗相比，PPT 在 t 时差异明显（20.69 N/mm），而 VAS 保持不变。多元线性回归显示，ECT 僵硬度和组群是竖脊肌僵硬度的预测因素。MFR 可能对亚极量离心性躯干伸展运动后疼痛、微循环和肌肉僵硬有积极影响，表明恢复更好，但需要进一步研究证实。
