The use of graduated compression stockings (GCS) in sport has been increasing in the last years due to their potential positive effects for athletes. However, there is little evidence to support whether these types of garments actually improve cardiorespiratory performance. The aim of this study was to examine the cardiorespiratory responses of GCS during running after three weeks of regular use. Twenty recreational runners performed three tests on different days: test 1) - a 5-min maximal effort run in order to determine the participants' maximal aerobic speed; and tests 2) and 3) - a fatigue running test of 30 minutes at 80% of their maximal aerobic speed with either GCS or PLACEBO stockings at random. Cardiorespiratory parameters (minute ventilation, heart rate, relative oxygen consumption, relative carbon dioxide production, ventilatory equivalents for oxygen and carbon dioxide, and oxygen pulse) were measured. Before each test in the laboratory, the participants trained with the randomly assigned stockings (GCS or PLACEBO) for three weeks. No significant differences between GCS and PLACEBO were found in any of the cardiorespiratory parameters. In conclusion, the present study provides evidence that running with GCS for three weeks does not influence cardiorespiratory parameters in recreational runners.
近年来，由于渐进式压力袜（GCS）对运动员可能具有积极影响，其在运动中的使用不断增加。然而，几乎没有证据支持这类服装是否真的能改善心肺功能。本研究的目的是在定期使用三周后，检查跑步过程中GCS对心肺的反应。20名休闲跑步者在不同日期进行了三项测试：测试1）——进行5分钟的全力跑以确定参与者的最大有氧速度；测试2）和测试3）——以最大有氧速度的80%进行30分钟的疲劳跑步测试，随机穿着GCS或安慰剂袜子。测量了心肺参数（分钟通气量、心率、相对耗氧量、相对二氧化碳产生量、氧和二氧化碳的通气当量以及氧脉搏）。在实验室的每次测试前，参与者穿着随机分配的袜子（GCS或安慰剂）训练三周。在任何心肺参数方面，GCS和安慰剂之间均未发现显著差异。总之，本研究提供的证据表明，休闲跑步者穿着GCS跑步三周不会影响心肺参数。
