本研究考察了竞技跑步者在跑步机上跑步期间和跑步后穿着不同等级的分级压力袜 (GCS) 对生理和感知测量的影响。九名男性和一名女性进行了 3 次 40 分钟跑步机跑步（80 +/- 5% 最大摄氧量），按照双盲平衡顺序佩戴对照（0 mmHg；CON）、低（12-15 mmHg；LO-GCS）或高（23-32 mmHg；HI-GCS）级 GCS。测量摄氧量、心率和血乳酸。在跑步前和跑步后使用感知量表来评估舒适度、紧张度以及与佩戴 GCS 相关的任何疼痛。通过测量肌酸激酶和肌红蛋白、反向运动跳跃高度、感知酸痛图和压力敏感性，在跑前、跑后立即以及跑后 24 和 48 小时确定肌肉功能、酸痛和损伤的变化。运动期间的摄氧量、心率或血乳酸试验之间没有显着差异。 HI-GCS 被认为比其他干预措施更严格（P < 0.05）并且更容易引起疼痛（P < 0.05）； CON 和 LO-GCS 被评为比 HI-GCS 更舒适 (P < 0.05)。跑步后肌酸激酶（P < 0.05）、肌红蛋白（P < 0.05）和跳跃高度（P < 0.05）较高，压力敏感性更明显（P < 0.05），但在24和48小时后则不再如此。只有四名参与者报告在跑步恢复过程中出现肌肉酸痛，并且试验之间的肌肉功能没有差异。总之，佩戴 GCS 的健康跑步者在跑步机跑步期间或之后没有体验到任何生理益处。然而，运动员在跑步时佩戴低档 GCS 感觉更舒服。
This study examined the effect of wearing different grades of graduated compression stockings (GCS) on physiological and perceptual measures during and following treadmill running in competitive runners. Nine males and one female performed three 40-min treadmill runs (80 +/- 5% maximal oxygen uptake) wearing either control (0 mmHg; CON), low (12-15 mmHg; LO-GCS), or high (23-32 mmHg; HI-GCS) grade GCS in a double-blind counterbalanced order. Oxygen uptake, heart rate and blood lactate were measured. Perceptual scales were used pre- and post-run to assess comfort, tightness and any pain associated with wearing GCS. Changes in muscle function, soreness and damage were determined pre-run, immediately after running and 24 and 48 h post-run by measuring creatine kinase and myoglobin, counter-movement jump height, perceived soreness diagrams, and pressure sensitivity. There were no significant differences between trials for oxygen uptake, heart rate or blood lactate during exercise. HI-GCS was perceived as tighter (P < 0.05) and more pain-inducing (P < 0.05) than the other interventions; CON and LO-GCS were rated more comfortable than HI-GCS (P < 0.05). Creatine kinase (P < 0.05), myoglobin (P < 0.05) and jump height (P < 0.05) were higher and pressure sensitivity was more pronounced (P < 0.05) immediately after running but not after 24 and 48 h. Only four participants reported muscle soreness during recovery from running and there were no differences in muscle function between trials. In conclusion, healthy runners wearing GCS did not experience any physiological benefits during or following treadmill running. However, athletes felt more comfortable wearing low-grade GCS whilst running.
