Due to the SARS-CoV-2 pandemic that affected the world in a short time, face masks were recommended by all authorities and started to be used widely. Few studies have reported the effects of face masks on cardiopulmonary capacity. In this critical period, there is a need to contribute to the literature to clarify the effects of face masks. The aim of the study was to examine the effect of face masks on cardiopulmonary capacity.
In this prospective cross-over study, the effect of wearing nomask (nm), surgical mask (cm) and FFP2/N95 (ffpm) mask was examined in 16 healthy individuals (age: 23.12±1.4, BMI: 22.91±12.8, 8 women). Forty-eight tests were performed randomly with the standard cycle ergometer. Time to exhaustion, maximum power, heart rate, dyspnea, respiratory frequency and oxygen saturation were evaluated. Ten domains of the comfort/discomfort levels of wearing mask were evaluated by questionnaire.
Time to exhaustion were 383±118, 348.25±106 and 338.62±97 seconds (nm, cm and ffpm, respectively; P<0.001). The maximum power was 125±31.62 Watt in all measurements. There was no significant differences in physiological parameters except dyspnea (P=0.004). A significant difference was found between the masks in terms of tightness and breathing resistance in terms of mask comfort/discomfort (P=0.001, P=0.02, respectively).
Cardiopulmonary exercise capacity was reduced in healthy young individuals due to surgical mask and ffpm/N95. In addition to this effect, breathing resistance and tightness should be considered in face masks recommendations during exercise.
由于 SARS-CoV-2 疫情在短时间内席卷全球,所有权威机构都建议佩戴口罩,并开始广泛使用。很少有研究报告口罩对面部心肺功能的影响。在这个关键时期,有必要为文献做出贡献,以阐明口罩的影响。本研究旨在研究口罩对面部心肺功能的影响。
在这项前瞻性交叉研究中,我们研究了不戴口罩(nm)、外科口罩(cm)和 FFP2/N95(ffpm)口罩对 16 名健康个体(年龄:23.12±1.4 岁,BMI:22.91±12.8kg/m²,8 名女性)心肺功能的影响。使用标准的测功计随机进行了 48 次测试。评估了疲劳时间、最大功率、心率、呼吸困难、呼吸频率和血氧饱和度。通过问卷评估了佩戴口罩的 10 个舒适度/不舒适度领域。
疲劳时间分别为 383±118、348.25±106 和 338.62±97 秒(nm、cm 和 ffpm,分别;P<0.001)。最大功率在所有测量中均为 125±31.62 瓦。除呼吸困难外(P=0.004),生理参数无显著差异。在口罩的舒适度/不舒适度方面,口罩的紧密度和呼吸阻力方面存在显著差异(P=0.001,P=0.02,分别)。
外科口罩和 ffpm/N95 会降低健康年轻个体的心肺运动能力。除了这种影响外,在运动时佩戴口罩的建议中,还应考虑呼吸阻力和紧密度。
