Abstract:
Individualized aerobic exercise treatment prescribed within 10 days of injury facilitates recovery in adolescents after sport-related concussion (SRC) and reduces incidence of persisting post-concussive symptoms (PPCSs) beyond 4 weeks. The effect of aerobic exercise treatment on quality of life symptoms is, however, unknown. This planned secondary aim of a published randomized controlled trial found that while adolescents prescribed aerobic exercise recovered faster, there was no difference on the Pediatric Quality of Life (PedsQL) questionnaire scores during the 4-week intervention period. Nevertheless, adolescents who experienced PPCS reported significantly worse initial visit (within 10 days of injury) symptoms on the PedsQL than those who recovered within 4 weeks. Higher scores on the PedsQL correlated with greater initial visit concussion symptom burden and more abnormalities on a concussion-relevant visio-vestibular examination. Thus, the PedsQL captures the clinical severity of concussion and is prognostic of risk for delayed recovery when administered early after SRC in adolescents.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
