Ulaszewska K. Gasior, J. S. Lewandowski, M. Kasiak P. S. Mamcarz, A. 14days. Speed, power, heart rate (HR), oxygen uptake (VO2), pulmonary ventilation, blood lactate concentration (at the anaerobic threshold (AT)), respiratory compensation point (RCP), and maximum exertion were measured before and after COVID-19 infection. Pearson`s and Spearman`s r correlation coefficients and Student t-test were applied to assess relationship between physiologic or exercise variables and time. Results: The anthropometric measurements did not differ significantly before and after COVID-19. There was a significant reduction in VO2 at the AT and RCP (both p < 0.001). Pre-COVID-19 VO2 was 34.97 ± 6.43mlkg·min-1, 43.88 ± 7.31mlkg·min-1 and 47.81 ± 7.81mlkg·min-1 respectively for AT, RCP and maximal and post-COVID-19 VO2 was 32.35 ± 5.93mlkg·min-1, 40.49 ± 6.63mlkg·min-1 and 44.97 ± 7.00mlkg·min-1 respectively for AT, RCP and maximal. Differences of HR at AT (p < 0.001) and RCP (p < 0.001) was observed. The HR before infection was 145.08 ± 10.82bpm for AT and 168.78 ± 9.01bpm for RCP and HR after infection was 141.12 ± 9.99bpm for AT and 165.14 ± 9.74bpm for RCP. Time-adjusted measures showed significance for body fat (r = 0.46, p < 0.001), fat mass (r = 0.33, p = 0.020), cycling power at the AT (r = -0.29, p = 0.045), and HR at RCP (r = -0.30, p = 0.036). Conclusion: A mild COVID-19 infection resulted in a decrease in EA`s CPET performance. The most significant changes were observed for VO2 and HR. Medical Professionals and Training Specialists should be aware of the consequences of a mild COVID-19 infection in order to recommend optimal therapeutic methods and properly adjust the intensity of training.]]> 0 Sat, 01 Jan 2022 22:03:41 +0100 https://sponet.de/sponet/Record/4078663 https://sponet.de/sponet/Record/4078663 Sliz, D.
