摘要

运动专用口罩(ESFM)对有氧运动者的生理、知觉、呼吸和表现反应的影响仍不清楚。此外,ESFM 如何减轻运动诱发的支气管收缩(EIB)也尚不清楚。因此,本研究旨在确定 ESFM 如何改变分级跑步机运动的运动内生理、知觉、呼吸和运动表现反应。24 人(11 名女性)在两种条件下(ESFM 和无掩蔽)在跑步机上完成了不连续的分级运动测试。对生理、呼吸功能和知觉测量进行了评估。测试成绩根据力竭时间确定。统计分析包括线性混合效应模型、重复测量方差分析和配对比较(α值为 0.05)。使用 ESFM 会严重影响运动表现(中位数 = -150.5 秒),并降低最大强度时的动脉血氧饱和度(平均值 = -3.7%)。空气饥饿感和呼吸功在次最大强度和最大强度时都有所升高。在亚极限强度下,感知到的体力消耗和呼吸不适明显增加,但在最大强度下没有增加。肺活量测量结果在运动结束时没有明显差异,但在亚极限强度时,有和没有 EIB 的参与者的肺活量测量结果有明显改善。身体健康的人使用 ESFM 会增加感官不适,影响运动表现,并增加动脉饱和度。呼吸功能有所改善,但伴随着不良的知觉感受。尽管如此,运动员的表现受损可能会限制 ESFM 在现实世界中的应用。

Influence of an Exercise-Specific Face Mask on Physiological and Perceptual Responses to Graded Exercise.

The impact of exercise-specific face masks (ESFMs) in aerobically fit individuals on physiological, perceptual, respiratory, and performance responses remains unclear. How ESFMs mitigate exercise-induced bronchoconstriction (EIB) is also unknown. Thus, this study aimed to determine how an ESFM altered within-exercise physiological, perceptual, respiratory, and performance responses to graded treadmill exercise. Twenty-four individuals (11 females) completed a discontinuous graded exercise test on a treadmill under two conditions (ESFM and unmasked). Physiological, respiratory function, and perceptual measures were assessed. Performance was determined by time to exhaustion. Statistical analyses included linear mixed-effects modeling, repeated measures analysis of variance, and pairwise comparisons using an alpha value of 0.05. ESFM use significantly impaired performance (median = -150.5 s) and decreased arterial oxygen saturation at maximal intensity (mean = -3.7%). Perceptions of air hunger and work of breathing were elevated across submaximal and maximal intensities. Perceived exertion and breathing discomfort were significantly elevated submaximally but not maximally. Spirometry measures were not significantly different at termination but were significantly improved at submaximal intensities in participants with and without EIB. ESFM use in fit individuals increased perceptual discomfort, impaired performance, and augmented arterial desaturation. Respiratory function improvements were observed but were accompanied by adverse perceptual sensations. Despite this, performance impairments may limit the real-world utility of ESFMs for athletes.
