Algorithm for initial exercise prescription

Outcome of BCBT	Initial target heart rate
Contraindicated because pre-test symptom VAS is 8 or higher	60% maxHR
BCBT is terminated because of symptom exacerbation	85% of the participants heart rate measured at BCBT termination.
Participants reach voluntary exhaustion (RPE of >17) or 90% maxHR without symptom exacerbation	85% of the participants heart rate measured at BCBT termination.

BCBT, Buffalo Concussion Bike Test; maxHR, maximum heart rate=208−(0.7×age); RPE, Rated Perceived Exertion Scale; VAS, Visual Analogue Scale for symptoms.
