Why the study?
Does recent COVID-19 vaccination alter physiological responses to graded exercise in physically active healthy people?
Does recent COVID-19 vaccination alter physiological responses to graded exercise in physically active healthy people?
Recent COVID-19 vaccination does not impair overall exercise capacity but causes small elevations in heart rate and norepinephrine during vigorous exercise.
Recent COVID-19 vaccination unlikely to impair exercise capacity in healthy adults; leaves open whether minor HR and norepinephrine rises affect performance.
Recent COVID-19 vaccination does not affect a large number of physiological responses to graded exercise, indicating that vaccination is unlikely to impair exercise capacity in normal healthy people. Heart rate and norepinephrine levels were elevated in response to exercise after the two-dose Pfizer mRNA vaccination compared to controls. Small elevations in cardiovascular and neuroendocrine responses to exercise after recent COVID-19 vaccination could have implications for exercise performance in elite athletes and warrants investigation.
