To study the recovery periods of blood flow parameters in muscles after anaerobic exercise, instantaneous and mean blood flow velocity curves were recorded in the femoral artery in 22 sportsmen at rest and during the first 4 min of recovery after exercise (Ruffier-Dickson test). A flat ultrasonic probe connected to a Doppler system (Flow-Tester) was fixed on the skin at the level of the common femoral artery. From Doppler recordings, we calculated periods of recovery (return to baseline) of femoral blood flow velocity (FBFV RP), heart rate (HR RP) and femoral stroke distance (FSD RP). Also, Ruffier-Dickson index (RDI), VO(2)max in mL/kg(-1)/min(-1) and number of training hours were determined. We observed a high correlation between FBFV RP and VO(2)max (p = 0. 0002), and significant correlation between FSD RP and VO(2)max (p = 0.0238) and RDI (p = 0.0451). In conclusion, there is a excellent correlation between blood flow velocity recovery period in femoral artery after moderate exercise and VO(2)max in high-level sportsmen. The method of testing is simple and based on conventional Doppler technique. It can be used for the follow-up of training levels in sportsmen.
为研究无氧运动后肌肉血流参数的恢复时间，在22名运动员休息时及运动后恢复的前4分钟（鲁菲耶 - 迪克森试验）记录股动脉的瞬时和平均血流速度曲线。将连接到多普勒系统（血流测试仪）的扁平超声探头固定在股总动脉水平的皮肤上。根据多普勒记录，我们计算了股血流速度（FBFV RP）、心率（HR RP）和股搏出距离（FSD RP）的恢复时间（恢复到基线）。此外，还测定了鲁菲耶 - 迪克森指数（RDI）、以毫升/千克⁻¹/分钟⁻¹为单位的最大摄氧量（VO₂max）和训练小时数。我们观察到FBFV RP与VO₂max之间存在高度相关性（p = 0.0002），FSD RP与VO₂max之间存在显著相关性（p = 0.0238）以及FSD RP与RDI之间存在显著相关性（p = 0.0451）。总之，高水平运动员中等强度运动后股动脉血流速度恢复时间与VO₂max之间存在极好的相关性。该测试方法简单，基于传统多普勒技术。它可用于运动员训练水平的跟踪监测。
