Ankle to brachial index after heavy load exercise is the most accurate way of diagnosing minor arterial lesions in athletes, such as endofibrosis. The reliability and practical aspects of ankle to brachial index measurements after heavy-load exercise have not been studied. The purpose of this study was to analyze the interest of oscillometric automatic vs. manual Doppler measurements, for the calculation of ankle to brachial index, after heavy-load exercise in athletes.
Prospective single-center study.
Fifteen healthy trained athletes performed an incremental test twice. Ankle to brachial index measurements were performed at Rest, as soon as possible after exercise (Rec-0), and then started at the 3rd minute of recovery (Rec-3), by two operators using each one of the two ankle to brachial index measurement methods.
Mean times for automatic vs. manual ankle to brachial availability were 99 ± 18 s vs. 113 ± 25 s (p = 0.005) and 44 ± 25 s vs. 53 ± 12 s (p = 0.001) respectively at Rec-0 and Rec-3. Ankle to brachial index values from the two methods were highly correlated (r = 0.89). Mean absolute differences of automatic vs. manual ankle to brachial values from test-retest were 0.04 ± 0.05 vs. 0.08 ± 0.08 (p > 0.05) and 0.07 ± 0.05 vs. 0.09 ± 0.10 (p > 0.05) at Rest and Rec-0.
Automatic method allows obtaining faster and simultaneously post-exercise ankle to brachial index measurement compare to the manual Doppler. This time issue does not result in a significant change in absolute ankle to brachial index values, nor in the absolute differences of these in test-retest. Nevertheless, the test-retest variability of post-exercise ankle to brachial index results seems smaller with the automatic than the manual method.
负重运动后踝臂指数是诊断运动员轻微动脉病变（如纤维组织内膜炎）最准确的方法。负重运动后踝臂指数测量的可靠性和实际应用方面尚未得到研究。本研究的目的是分析在运动员负重运动后，采用示波自动测量与手动多普勒测量来计算踝臂指数的价值。
前瞻性单中心研究。
15名健康的受过训练的运动员进行了两次递增测试。由两名操作人员分别使用两种踝臂指数测量方法，在静息状态、运动后尽快（恢复0分钟）以及恢复第3分钟时进行踝臂指数测量。
在恢复0分钟和恢复3分钟时，自动测量与手动测量获得踝臂指数的平均时间分别为99±18秒对113±25秒（p = 0.005）和44±25秒对53±12秒（p = 0.001）。两种方法测得的踝臂指数值高度相关（r = 0.89）。重测时自动测量与手动测量的踝臂指数值的平均绝对差值在静息状态和恢复0分钟时分别为0.04±0.05对0.08±0.08（p>0.05）和0.07±0.05对0.09±0.10（p>0.05）。
与手动多普勒测量相比，自动测量方法能更快地同时获得运动后的踝臂指数测量结果。这个时间问题不会导致踝臂指数绝对值的显著变化，也不会导致重测时这些值的绝对差值出现显著变化。然而，运动后踝臂指数结果的重测变异性似乎自动测量方法比手动测量方法更小。
