To determine the effects of wearing graduated compression stockings (GCS) on the exercise response, twelve high fit males served as subjects in a series of two experiments. The first experiment consisted of six subjects performing two tests of maximal oxygen consumption (VO2 max) on a treadmill with and without GCS. The second experiment consisted of six subjects performing three separate three minute tests on a bicycle ergometer at 110% of their VO2 max. The experimental conditions for the three tests were: GCS worn during the test and recovery (GCS), GCS worn only during the test (GCS-O/O) and no stockings worn during either the test or recovery (NO-GCS). Oxygen consumption (VO2) was measured at rest, throughout the duration of all tests and during recovery in both experiments. Blood samples were obtained at rest and at 5, 15, 30, 45 and 60 minutes post exercise in the first experiment and at rest and at 5, 15 and 30 minutes post exercise in the second experiment for the determination of lactate and hematocrit. The use of GCS in the first experiment resulted in no significant difference in VO2 max, recovery VO2 or plasma volume shifts. Lactate values were lower throughout the duration of the recovery period with the 15 minute values being significantly different with the use of GCS. Significant differences in post exercise blood lactate values were found in the second experiment. The GCS trial resulted in significantly less lactate when compared to the GCS-O/O and the NO-GCS trials. There was no significant difference in post exercise lactate values between the NO-GCS and the GCS-O/O trials. Plasma volume changes were not significantly different among trials. Results of both experiments showed recovery lactate values to be lower with the use of GCS. These lower values are not ascribable to plasma volume shifts but rather appear to be due to an inverse gradient created by the GCS resulting in the lactate being retained in the muscular bed.
为了确定穿着分级压力袜（GCS）对运动反应的影响，12名健康状况良好的男性在一系列两项实验中作为受试者。第一个实验包括6名受试者在跑步机上进行两次最大耗氧量（VO2 max）测试，一次穿着GCS，一次不穿。第二个实验包括6名受试者在自行车测力计上以其VO2 max的110%进行三次单独的三分钟测试。三项测试的实验条件分别为：测试和恢复期间都穿着GCS（GCS）、仅在测试期间穿着GCS（GCS-O/O）以及测试和恢复期间都不穿袜子（NO-GCS）。在两项实验中，均在休息时、所有测试期间以及恢复期间测量耗氧量（VO2）。在第一个实验中，于休息时以及运动后5、15、30、45和60分钟采集血样；在第二个实验中，于休息时以及运动后5、15和30分钟采集血样，以测定乳酸和血细胞比容。在第一个实验中，使用GCS对VO2 max、恢复VO2或血浆容量变化没有显著影响。在恢复期间，使用GCS时，整个恢复期间的乳酸值较低，15分钟时的值有显著差异。在第二个实验中，运动后血乳酸值存在显著差异。与GCS-O/O和NO-GCS试验相比，GCS试验的乳酸显著减少。NO-GCS和GCS-O/O试验之间运动后乳酸值没有显著差异。各试验之间血浆容量变化没有显著差异。两项实验的结果均显示，使用GCS时恢复乳酸值较低。这些较低的值并非归因于血浆容量变化，而是似乎由于GCS产生的反向梯度导致乳酸保留在肌肉床中。
