摘要

控制体力活动可能有助于预防和治疗血管病理的工具。在这项研究中,我们旨在了解下肢运动如何影响健康队列的灌注。本研究的方便样本包括18名事先选择的男女健康个体(n=9),平均年龄32.8±12.7岁。程序遵循良好临床规范的所有原则。采用激光多普勒血流仪(LDF)和偏振光谱学(PSp)同时评估双脚背区血液灌注变化。在基线、稳定后(第一阶段)、两足等距跖屈1分钟后(第二阶段)和恢复期间(第三阶段)进行测量。进行描述性统计和比较统计。足底屈曲引起了两足明显的灌注改变,但方向相反——随LDF增加而减少,随PSp减少。这些变化表明,这种方法促进了血液从浅神经丛向深神经丛的适应性动员。动脉血压和心脏频率没有明显变化。这种操作不需要专门的监督,能够促进下肢显著的灌注改变,在未来的研究中显示出在预防/恢复背景下的前瞻性设计的潜力。关键词:足底屈曲;脚灌注;激光多普勒血流测量;分化的光谱学;PAHR -提示适应性血流动力学反应;身体活动;家庭健康

Short duration – low intensity isometric plantar flexion increases distal perfusion: observations from a healthy cohort
Controlled physical activity might help as a preventive and therapeutic tool in vascular pathology. In this study we aimed to understand how lower limb exercise impacts perfusion in a healthy cohort. The study involved a convenience sample of eighteen previously selected healthy individuals of both sexes (n=9 each), mean age 32.8 ± 12.7 years. Procedures respected all principles of good clinical practice. Blood perfusion changes were simultaneously assessed in the dorsal region of both feet by laser Doppler flowmetry (LDF) and polarised spectroscopy (PSp). Measurements were taken at baseline, after stabilization (phase I), following 1 minute of bipedal isometric plantar flexion (phase II), and during recovery (phase III). Descriptive and comparative statistics were performed. Plantar flexion evoked significant perfusion changes in both feet, but in opposite directions – increasing with LDF and decreasing with PSp. These changes indicate that this approach promotes an adaptive mobilisation of blood from superficial to the deeper plexus. No significant changes in arterial blood pressure or cardiac frequency were detected. This manoeuvre, needing no specialised supervision, is capable of promoting significant perfusion changes in the lower limb, showing potential to be further explored in future studies with a prospective design in a preventive/recovery context. Keywords: plantar flexion; foot perfusion; laser Doppler flowmetry; polarised spectroscopy; PAHR - prompt adaptive hemodynamical response; physical activity; home-health
