Recent COVID-19 vaccination has minimal effects on the physiological responses to graded exercise in physically active healthy people.

ABSTRACT: Athletes are advised to receive the COVID-19 vaccination to protect themselves from SARS-CoV-2 infection during major competitions. Despite this, many athletes are reluctant to get the COVID-19 vaccine due to concerns that symptoms of vaccinosis may impair athletic performance. This study aimed to determine the effects of COVID-19 vaccination on the physiological responses to graded exercise. Healthy physically active participants completed a 20-min bout of graded cycling exercise at intensities corresponding to 50%, 60%, 70%, and 80% of the predetermined V̇O_2max before and ∼21 days after receiving the COVID-19 vaccine (2-dose Pfizer mRNA or 1-dose Johnson & Johnson). Vaccination had no effect on a large number of physiological responses to exercise measured in blood (e.g., lact
