Cardiovascular and Respiratory Responses During Graded Exercise in Adolescents After Sport-Related Concussion.

ABSTRACT:

Background

Symptom-limited exercise intolerance is a physiological sign of sport-related concussion. Possible etiologies include rest-induced aerobic deconditioning and/or impaired cardiopulmonary function.

Objective

This study examined cardiovascular and respiratory function at rest and during progressive cycle ergometer exercise in adolescents within 10 days of sport-related concussion compared with non-concussed athletes.

Methods

Concussed participants (n = 26, 15.4 ± 1.1 years, 54% male, 7.3 ± 1.8 days from injury) and control participants (n = 24, 15.8 ± 1.6 years, 58% male) performed the Buffalo Concussion Bike Test.
