Abstract

OBJECTIVE

The objective of this study was to analyze the effect of graduated compression stockings (GCS) on venous lower limb hemodynamics in healthy amateur runners.

METHODS

Ten runners were evaluated during rest and after a 10-km run without and with knee-high GCS of 20 to 30 mm Hg. Air plethysmography evaluated venous filling index (VFI), ejection fraction, and residual volume fraction (RVF) in both limbs. Capillary lactate level and heart rate were also measured.

RESULTS

Right VFI was 1.38 mL/s during rest, 1.98 mL/s without compression, and 1.32 mL/s with compression (P = .006). Left VFI was 1.35 mL/s during rest, 1.64 mL/s without compression, and 1.21 mL/s with compression (P = .006). In both limbs, ejection fraction was not different in the three situations. Right RVF was 22.35% during rest, 19.40% without compression, and 10.50% with compression (P = .006). Left RVF was similar in all situations. Capillary lactate level increased in runners without compression (P = .004) but kept stable in those wearing compression. The difference between after-run and before-run capillary lactate levels was similar in runners with and without compression. Rest, peak, and after-run heart rates were similar in runners with and without compression.

CONCLUSIONS

Healthy amateur runners had associated hemodynamic improvements when wearing knee-high GCS of 20 to 30 mm Hg during a 10-km treadmill run. VFI dropped in both limbs and RVF dropped at least in the right limb. There was no positive effect on calf muscle pump; capillary lactate variation; or rest, peak, and after-run heart rates.

摘要

目的

本研究旨在分析梯度压力弹力袜（GCS）对健康业余跑步者下肢静脉血流动力学的影响。

方法

在休息时和 10 公里跑步后，10 名跑步者分别评估了不穿和穿膝高 20-30mmHg GCS 的情况。空气体积描记法评估了双侧的静脉充盈指数（VFI）、射血分数和残余容积分数（RVF）。还测量了毛细血管乳酸水平和心率。

结果

右 VFI 在休息时为 1.38mL/s，不穿压缩袜时为 1.98mL/s，穿压缩袜时为 1.32mL/s（P=0.006）。左 VFI 在休息时为 1.35mL/s，不穿压缩袜时为 1.64mL/s，穿压缩袜时为 1.21mL/s（P=0.006）。在两条腿中，三种情况下的射血分数没有差异。右 RVF 在休息时为 22.35%，不穿压缩袜时为 19.40%，穿压缩袜时为 10.50%（P=0.006）。左 RVF 在所有情况下均相似。不穿压缩袜的跑步者毛细血管乳酸水平升高（P=0.004），但穿压缩袜的跑步者保持稳定。不穿压缩袜的跑步者跑步后的毛细血管乳酸水平与跑步前相比的差异与穿压缩袜的跑步者相似。不穿和穿压缩袜的跑步者休息时、峰值时和跑步后的心率相似。
