Abstract

Background: The SARS-CoV-2 virus and its long-term consequences in adolescents have a global impact on upcoming medical issues. The aim of this study was to investigate the effects of a SARS-CoV-2 infection on cardiorespiratory parameters in young athletes.

Methods: In a cohort study involving repeated measurements during a six-month period, cardiorespiratory parameters were assessed in infected (SCoV) and non-infected (noSCoV) athletes. We evaluated handball players (17.2 ± 1.0 years) via performance diagnostics and a specific examination after a SARS-CoV-2 infection or without.

Results: We observed no significant differences between the two groups at the first visit. But between the first and second visit, the SCoV group's maximum power output was significantly lower than the noSCoV group's (- 48.3 ± 12.5; p ≤ 0.01 vs. - 15.0 ± 26.0 W; p = 0.09). At the second visit, lung diffusion capacity (DLCO/VA, %predicted) did not differ between groups (111.6 ± 11.5 vs. 116.1 ± 11.8%; p = 0.45). HR during comparative stress showed no group differences. The SCoV group's mean oxygen uptake during incremental exercise was lower (Two-way-ANOVA: 1912 vs. 2106 ml; p ≤ 0.01; mean difference: - 194 ml; 95% CI - 317 to - 71); we also noted a significantly lower stroke volume course during exercise (Two-way-ANAOVA: 147.5 vs. 169.5 ml; mean difference: - 22 ml; p ≤ 0.01; 95% CI - 34.2 to - 9.9). The probability of premature ventricular complexes after a SARS-CoV-2 infection yielded an odds ratio of 1.6 (95% CI 0.24-10.81).

Conclusions: The physical performance of young athletes infected with SARS-CoV-2 was impaired. This decreased performance is probably due to cardiac and/or peripheral deconditioning. Studies with larger cohorts are needed to make more profound conclusions.

有和没有SARS-CoV-2感染的年轻竞技手球运动员的重复心肺性能测量
背景:SARS-CoV-2病毒及其在青少年中的长期后果对即将到来的医疗问题具有全球性影响。本研究的目的是调查SARS-CoV-2感染对年轻运动员心肺参数的影响。方法:在一项为期六个月的重复测量的队列研究中,对感染(SCoV)和未感染(noSCoV)运动员的心肺参数进行了评估。我们对手球运动员(17.2±1.0岁)在感染SARS-CoV-2或未感染后进行了表现诊断和特异性检查。结果:两组患者首次访视无明显差异。但在第一次和第二次访问之间,SCoV组的最大功率输出显著低于noSCoV组(- 48.3±12.5;p≤0.01 vs. - 15.0±26.0 W;p = 0.09)。第二次访视时,两组间肺弥散能力(DLCO/VA,预测百分比)无差异(111.6±11.5 vs 116.1±11.8%;p = 0.45)。比较应激时的HR无组间差异。SCoV组在增量运动期间的平均摄氧量较低(双向方差分析:1912 vs. 2106 ml;p≤0.01;平均差值:- 194毫升;95% CI - 317至- 71);我们还注意到运动期间卒中容量过程显著降低(双向anaova: 147.5 vs 169.5 ml;平均差值:- 22毫升;p≤0.01;95% CI - 34.2至- 9.9)。SARS-CoV-2感染后发生过早心室复合体的几率为1.6 (95% CI 0.24-10.81)。结论:青少年运动员感染SARS-CoV-2后身体机能受到影响。这种下降的性能可能是由于心脏和/或外周的条件反射。需要更大规模的研究才能得出更深刻的结论。
