Abstract
CONTEXT : SARS-CoV-2 infection can affect the exercise response in athletes. Factors associated with the exercise response have not been reported.
OBJECTIVE : To (1) describe heart rate (HR), systolic blood pressure (SBP), and rating of perceived exertion (RPE) responses to exercise in athletes with a recent SARS-CoV-2 infection and (2) identify factors affecting exercise Responses.
DESIGN : Cross-sectional, experimental study.
PATIENTS OR OTHER PARTCIPANTS : Male and female athletes (age ¼ 24.2 6 6.3 years) with a recent (,28 days) SARS-CoV-2 infection (n ¼ 72).
SETTING : A COVID-19 Recovery Clinic for athletes.
MAIN OUTCOME MEASURE(S) : Heart rate, SBP, and RPE were measured during submaximal exercise (modified Bruce protocol) at 10 to 28 days after SARS-CoV-2 symptom onset. Selected factors (demographics, sport, comorbidities,
pre-infection training variables, and symptoms during the acute phase of the infection) affecting the exercise response were analyzed using random coefficient (linear mixed) models.
RESULTS : Heart rate, SBP, and RPE increased progressively from rest to stage 5 of the exercise test (P ¼ .0001). At stage 5 (10.1 metabolic equivalents), a higher HR and a higher SBP during exercise were associated with younger age (P ¼ .0007) and increased body mass index (BMI; P ¼ .009), respectively. Higher
RPE during exercise was significantly associated with a greater number of whole-body (P ¼ .006) and total number (P ¼ .004) of symptoms during the acute phase of infection.
CONCLUSIONS : A greater number of symptoms during the acute infection was associated with a higher RPE during exercise in athletes at 10 to 28 days after SARS-CoV-2 infection. We recommend measuring RPE during the first exercise challenge after infection, as this may indicate disease severity and be valuable for tracking progress, recovery, and return to sport.
