The aim of this study was to examine the effects of ionized and nonionized compression tights on sprint and endurance cycling performance. Using a randomized, blind, crossover design, 10 well-trained male athletes (age: 34.6 ± 6.8 years, height: 1.80 ± 0.05 m, body mass: 82.2 ± 10.4 kg, VO2max: 50.86 ± 6.81 ml·kg(-1)·min(-1)) performed 3 sprint trials (30-second sprint at 150% of the power output required to elicit VO2max [pVO2max] + 3 minutes recovery at 40% pVO2max + 30-second Wingate test + 3 minutes recovery at 40% pVO2max) and 3 endurance trials (30 minutes at 60% pVO2max + 5 minutes stationary recovery + 10-km time trial) wearing nonionized compression tights, ionized compression tights, or standard running tights (control). There was no significant effect of garment type on key Wingate measures of peak power (grand mean: 1,164 ± 219 W, p = 0.812), mean power (grand mean: 716 ± 68 W, p = 0.800), or fatigue (grand mean: 66.5 ± 6.9%, p = 0.106). There was an effect of garment type on blood lactate in the sprint and the endurance trials (p < 0.05), although post hoc tests only detected a significant difference between the control and the nonionized conditions in the endurance trial (mean difference: 0.55 mmol·L(-1), 95% likely range: 0.1-1.1 mmol·L(-1)). Relative to control, oxygen uptake (p = 0.703), heart rate (p = 0.774), and time trial performance (grand mean: 14.77 ± 0.74 minutes, p = 0.790) were unaffected by either type of compression garment during endurance cycling. Despite widespread use in sport, neither ionized nor nonionized compression tights had any significant effect on sprint or endurance cycling performance.
本研究旨在探讨离子化和非离子化压缩裤对短跑和耐力自行车运动表现的影响。采用随机、盲法、交叉设计，10 名训练有素的男性运动员（年龄：34.6±6.8 岁，身高：1.80±0.05 m，体重：82.2±10.4 kg，最大摄氧量：50.86±6.81 ml·kg(-1)·min(-1)）进行了 3 次短跑试验（30 秒冲刺，强度为最大摄氧量的 150%[pVO2max]，恢复 3 分钟，强度为 40%pVO2max，然后进行 30 秒的瓦格纳测试，恢复 3 分钟，强度为 40%pVO2max）和 3 次耐力试验（30 分钟，强度为 60%pVO2max，恢复 5 分钟，然后进行 10 公里计时赛），分别穿着非离子化压缩裤、离子化压缩裤或标准跑步裤（对照）。服装类型对关键的瓦格纳指标峰值功率（总平均值：1164±219 W，p=0.812）、平均功率（总平均值：716±68 W，p=0.800）或疲劳（总平均值：66.5±6.9%，p=0.106）没有显著影响。服装类型对短跑和耐力试验中的血乳酸有影响（p<0.05），尽管事后检验仅在耐力试验中检测到对照和非离子化条件之间存在显著差异（平均差异：0.55 mmol·L(-1)，95%置信区间：0.1-1.1 mmol·L(-1)）。与对照相比，两种压缩服装在耐力自行车运动中对耗氧量（p=0.703）、心率（p=0.774）和计时赛成绩（总平均值：14.77±0.74 分钟，p=0.790）均无影响。尽管在运动中广泛使用，但离子化和非离子化压缩裤对短跑和耐力自行车运动表现均无显著影响。
