The aims of this study were to examine the effect of SARS-CoV-2 infection on cardiorespiratory fitness (CRF) and time-trial performance in vaccinated well-trained young kayak athletes. This is a longitudinal observational study. Sixteen (7 male, 9 female) vaccinated kayakers underwent body composition assessment, maximal graded exercise test, and 1000-m time-trial tests 21. 9 +/- 1. 7 days before and 66. 0 +/- 2. 2 days after the SARS-CoV-2 infection. The perception of training load was quantified with Borg’s CR-10 scale before and after the infection return to sport period. There were significant decreases in peak oxygen uptake (-9. 7 %; effect size [ES] = 1. 38), peak oxygen pulse (-5. 7 %; ES = 0. 96), and peak heart rate (-1. 9 %; ES = 0. 61). Peak minute ventilation, and minute ventilation/carbon dioxide production slope were unchanged after infection compared to the pre-infection values. In the entire 1000-m, the impaired tendencies were found in completion time, mean power, and mean speed (-2. 4 to 1. 2 %; small ESs = -0. 40 to 0. 47) as well as significant changes in stroke rate and stroke length (-4. 5 to 3. 7 %; ESs = -0. 60 to 0. 73). SARS-CoV-2 infection decreased CRF and time-trial performance even two months after return to regular training in vaccinated athletes.
