OBJECTIVE
In view of the current COVID-19 pandemic, the objective of this study was to determine, through a systematic review and meta-analysis, whether the use of N95/FFP2 masks during aerobic exercise has a significant impact on HR, RR, SpO2, and blood pressure (BP) in healthy individuals.
METHODS
We searched the MEDLINE database for studies published in English between 2005 and 2021. To reduce bias and increase reliability, only randomized controlled trials and randomized crossover clinical trials were considered for inclusion. The selected outcomes included HR, RR, SpO2, and BP, with perceived exertion being evaluated by means of the Borg scale.
RESULTS
Eight controlled trials were included in the meta-analysis. Seven evaluated HR (p > 0.05), five evaluated RR (p > 0.05), five evaluated SpO2 and BP (p > 0.05 for both), and six evaluated perceived exertion, presenting controversial results such as risk ratios that were grouped for each variable.
CONCLUSIONS
This study suggests that N95 and FFP2 masks do not have significant effects on HR, RR, SpO2, and BP during aerobic exercise in healthy individuals.
目的
鉴于当前的 COVID-19 大流行，本研究旨在通过系统评价和荟萃分析确定，在健康个体进行有氧运动时使用 N95/FFP2 口罩是否会对心率（HR）、呼吸频率（RR）、血氧饱和度（SpO2）和血压（BP）产生显著影响。
方法
我们检索了 MEDLINE 数据库中 2005 年至 2021 年间发表的英文研究。为了降低偏倚并提高可靠性，仅考虑纳入随机对照试验和随机交叉临床试验。选择的结果包括 HR、RR、SpO2 和 BP，通过 Borg 量表评估感知用力。
结果
荟萃分析纳入了八项对照试验。其中七项评估了 HR（p＞0.05），五项评估了 RR（p＞0.05），五项评估了 SpO2 和 BP（两者均为 p＞0.05），六项评估了感知用力，呈现出有争议的结果，例如按每个变量分组的风险比。
结论
本研究表明，在健康个体进行有氧运动时，N95 和 FFP2 口罩对 HR、RR、SpO2 和 BP 没有显著影响。
