摘要本研究的目的是探讨在长时间的试跑过程中，穿着压缩袜子(CS)对运动指标和生理反应的影响。11名训练有素的跑步者在佩戴或不佩戴CS的情况下，以比赛强度完成了15.6公里的试跑。采用近红外光谱仪(NIRS)测定运动前后股外侧肌的反跳跃、最大自主收缩和氧合情况。在CS和非CS期间评估跑步时间、心率(HR)、血乳酸浓度和感觉到的劳累程度。在运行过程中，没有观察到任何因变量的显著差异。在非CS和CS条件下，运行时间分别为5681.1±503.5和5696.7±530.7 S。CS和非CS运行时的相对强度对应于90.5-91.5%HRmax的范围。尽管运动后肌肉摄氧量和肌肉血流量等NIRS指标显著增加(CS组和非CS组分别为+57.7%和+42.6%，+59.2%和+32.4%，P<；0.05)，但两种跑步条件之间没有差异。研究结果表明，竞技跑步者在长时间的越野跑步中佩戴CS并不会获得任何实际或生理上的好处。
Abstract The objective of this study was to investigate the effects of wearing compression socks (CS) on performance indicators and physiological responses during prolonged trail running. Eleven trained runners completed a 15.6 km trail run at a competition intensity whilst wearing or not wearing CS. Counter movement jump, maximal voluntary contraction and the oxygenation profile of vastus lateralis muscle using near-infrared spectroscopy (NIRS) method were measured before and following exercise. Run time, heart rate (HR), blood lactate concentration and ratings of perceived exertion were evaluated during the CS and non-CS sessions. No significant difference in any dependent variables was observed during the run sessions. Run times were 5681.1±503.5 and 5696.7±530.7 s for the non-CS and CS conditions, respectively. The relative intensity during CS and non-CS runs corresponded to a range of 90.5–91.5% HRmax. Although NIRS measurements such as muscle oxygen uptake and muscle blood flow significantly increased following exercise (+57.7% and + 42.6%,+59.2% and + 32.4%, respectively for the CS and non-CS sessions, P<0.05), there was no difference between the run conditions. The findings suggest that competitive runners do not gain any practical or physiological benefits from wearing CS during prolonged off-road running.
