The aim of this study was to examine the effect of breathing a hyperoxic gas mixture on recovery kinetics after a simulated soccer match protocol. In a double-blind, randomized design, twenty-eight semi-professional soccer players completed the Loughborough Intermittent Shuttle Test (LIST) followed by the administration of either a hyperoxic (FIO = 99.5%: HYP) or a normoxic gas mixture (FIO = 21%: NORM). HYP and NORM were administered immediately after LIST and daily for the next 3 days for 15 minutes. Physical performance (squat jump: SJ, countermovement jump: CMJ, maximal voluntary contraction: MVC, and 20 m sprint: SP), blood concentrations of muscle damage markers (creatine kinase: CK, lactate dehydrogenase: LDH), marker of inflammation (C-reactive protein: CRP) and Hooper index (HI) were assessed at baseline, 15 minutes and 24 h, 48 h and 72 h following the LIST. SJ, CMJ, MVC, and SP were lower at 15 min, 24 h, and 48 h in both conditions compared to the prior LIST (p < 0.05). However, the decrease in MVC was significantly attenuated at 15 min, 24 h and 48 h in HYP compared to the NORM condition (p < 0.01). Likewise, HI, muscle soreness and fatigue scores were significantly lower in HYP compared to the NORM condition up to 48 h following the LIST (p < 0.01). The present study suggests that the application of HYP immediately after a simulated soccer match and for the next 3 days promoted a lower fatigue-induced decrement in MVC and restored perceptual parameters of fatigue in semi-professional players.
本研究的目的是检验在模拟足球比赛方案后呼吸高氧混合气体对恢复动力学的影响。在一项双盲、随机设计中，28名半职业足球运动员完成了拉夫堡间歇性穿梭测试（LIST），随后给予高氧（FIO = 99.5%：HYP）或常氧混合气体（FIO = 21%：NORM）。HYP和NORM在LIST后立即给予，接下来3天每天给予15分钟。在基线、LIST后15分钟、24小时、48小时和72小时评估身体性能（深蹲跳：SJ、反向移动跳：CMJ、最大自主收缩：MVC和20米冲刺：SP）、肌肉损伤标志物（肌酸激酶：CK、乳酸脱氢酶：LDH）的血液浓度、炎症标志物（C反应蛋白：CRP）和胡珀指数（HI）。与LIST前相比，两种情况下15分钟、24小时和48小时时的SJ、CMJ、MVC和SP均较低（p < 0.05）。然而，与NORM组相比，HYP组在15分钟、24小时和48小时时MVC的下降明显减弱（p < 0.01）。同样，与NORM组相比，LIST后48小时内HYP组的HI、肌肉酸痛和疲劳评分显著更低（p < 0.01）。本研究表明，在模拟足球比赛后立即及接下来3天应用HYP可使半职业球员中由疲劳引起的MVC下降更低，并恢复疲劳的感知参数。
