Repeated cardiopulmonary performance measurements in young competitive handball players with and without SARS-CoV-2 infection
(Wiederholte kardiopulmonale Leistungsmessungen bei jungen Leistungshandballern mit und ohne SARS-CoV-2-Infektion)
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.
