“…This modification was required because it takes longer to reach a physiological steady state on a cycle ergometer versus a treadmill. 8,9 We reduced the absolute workload for each bike stage by 10% from the treadmill because pilot participants reached leg muscle exhaustion well before their age-predicted maximal HR, which has been reported in another study of stationary cycling versus treadmill running in 300 healthy males. 6 Graded exercise tests performed on a cycle ergometer typically elicit maximum VO 2 values that are lower than those achieved on a treadmill yet elicit similar HR at maximal exercise.…”

Background: The Buffalo Concussion Treadmill Test (BCTT) is a graded exertion test for assessing exercise tolerance after concussion, but its utility is limited for certain populations. Hypothesis: We developed the Buffalo Concussion Bike Test (BCBT) and tested its comparability with the BCTT. We hypothesize that heart rate (HR) at symptom exacerbation on the BCBT will be equivalent to the BCTT. Study Design: Case-control study. Level of Evidence: Level 3. Methods: Adolescents with acute concussion (AC) (n = 20; mean age, 15.9 ± 1.1 years; 60% male) presenting to a concussion clinic within 10 days of injury and age- and sex-matched healthy controls (n = 20; mean age, 15.9 ± 1.1 years; 60% male) performed the BCTT at first visit and returned within 3 days to perform the BCBT. Test duration, HR, symptom severity (measured using a visual analog scale), and exertion (measured using the Borg Rating of Perceived Exertion) were collected during each test. Results: Adolescents with AC who were exercise intolerant on the BCTT were also intolerant on the BCBT, with symptom exacerbation occurring at a mean 8.1 ± 2.8 minutes on the BCTT versus 14.6 ± 6.0 minutes on the BCBT ( P < 0.01). Two 1-sided t tests showed that the HR at symptom exacerbation in AC patients (137 ± 28 bpm on BCTT vs 135 ± 25 bpm on BCBT; 95% CI, <0.01-0.03) and at voluntary exhaustion for controls (175 ± 13 bpm on BCTT vs 175 ± 13 bpm on BCBT; 95% CI, 0.03-0.03) on each test were statistically equivalent. Conclusion: The HR at symptom exacerbation on BCBT is equivalent to the BCTT for the assessment of exercise tolerance after concussion in adolescents. Clinical Relevance: The BCBT can be used in patients with limited mobility or for research interventions that require limited participant motion.
