There are multiple postexercise recovery technologies available in the market based on the assumption of blood-flow enhancement. Lower-limb intermittent pneumatic compression (IPC) has been widely used, but the available scientific evidence supporting its effectiveness remains scarce, requiring a deeper investigation into its underlying mechanisms. The aim of this study was to assess the hemodynamic effects caused by the use of IPC at rest.
Twenty-two soccer and track and field athletes underwent two 15-minute IPC protocols (moderate- [80 mm Hg] and high-pressure [200 mm Hg]) in a randomized order. Systolic peak velocity, end-diastolic peak velocity, arterial diameter, and heart rate were measured before, during (at the eighth minute), and 2 minutes after each IPC protocol.
Significant effects were observed between before and during (eighth minute) the IPC protocol for measures of systolic (P < .001) and end-diastolic peak velocities (P < .001), with the greater effects observed during the high-pressure protocol. Moreover, 2 minutes after each IPC protocol, hemodynamic variables returned to values close to baseline. Arterial diameter presented significant differences between pressures during the IPC protocols (P < .05), while heart rate remained unaltered.
IPC effectively enhances transitory blood flow of athletes, particularly when applying high-pressure protocols.
市场上有多种基于血流增强假设的运动后恢复技术。下肢间歇性气动压缩（IPC）已被广泛应用，但支持其有效性的现有科学证据仍然很少，需要更深入地研究其潜在机制。本研究旨在评估在休息时使用 IPC 引起的血液动力学效应。
22 名足球和田径运动员以随机顺序先后进行了两次 15 分钟的 IPC 方案（中压[80mmHg]和高压[200mmHg]）。在每个 IPC 方案之前、期间（第 8 分钟）和之后 2 分钟测量收缩期峰值速度、舒张末期峰值速度、动脉直径和心率。
IPC 方案期间（第 8 分钟）与之前的收缩期（P<.001）和舒张末期峰值速度（P<.001）测量值之间存在显著差异，高压方案的影响更大。此外，在每个 IPC 方案结束后 2 分钟，血流动力学变量恢复到接近基线的值。IPC 方案期间动脉直径在压力之间存在显著差异（P<.05），而心率保持不变。
IPC 有效地增强了运动员的短暂血流，特别是在应用高压方案时。
